The 4k Samsung KU6300 Series UHD LED TV doesn't have a stellar picture quality but is good enough for most content. It supports an HDR input, but it doesn't have the capabilities to display a more colorful picture. It also suffers from bad reflections and constant judder on movies. When watched from the side, its picture quality also diminishes.

The Samsung KU6300 delivers the same look and design as last year's Samsung J5000, J5200 and J5500, keeping it simple for a standard budget television. The borders are still average, and the stand, while still stable, has a wide footprint.

The Samsung KU6300 has a good picture quality overall. High quality content like Blu-rays appears richly detailed and lower quality content like DVDs and cable TV doesn't look bad at all. Even with the lights out, dark scenes appears deep, thanks to its high contrast ration and good black uniformity. The KU6300 does have some down sides though. The viewing angle is limited due to the VA panel it's using and its gray uniformity is also not so great.

Good value:
Full-array/direct lighting is better for local dimming. As for the uniformity of the screen, it depends on the implementation. Some edge-lit TVs have more uniform blacks than some full-array TVs.
There is no local dimming option on this TV, so the blacks cannot get darker.

The Samsung KU6300 can display our gradient test image fairly well. On our test picture, the gradation is smooth overall in the light shades with some small anomalies in the darker shades, especially in the green color. But it should not be an issue in regular content.
Update 10/26/2016: Our original test was showing 8 bit gradations due to incorrect drivers on our system. After some correction to our test apparatus, we have retested the color depth and found that it is able to display a 10 bit gradient smoothly.

Sound on the Samsung KU6300 isn't that bad when it isn't at its maximum volume. Still, even a budget sound bar would be way better than the TV speakers and would be recommended for anyone that care about sound.

Smart OS: Tizen (2016)
Just like the Samsung KS Series, it includes the new Tizen 2016 platform, with some minor differences. In terms of the applications, the KU6300 has less pre-loaded application than the KS Series, this shouldn’t be a problem though since you can download them from the menu either way. The performance slacks, as menus would freeze often for a lengthy duration, and the remote would flash and disconnect because of it.
The remote is very similar to the Samsung KS series with some differences. The back of the remote has a reflective plastic that will easily track finger prints, unlike the Samsung KS Series gray reflective plastic, the buttons protrude out rather than being inwards and the volume up and down, as well as the channel up and down buttons are black rather than chrome. The remote also weighs less than the KS Series remote and lacks the microphone option.
Differences between Sizes and Variants
We tested the 55" (UN55KU6300) version FA01. For the most part, we expect our review to be valid for the other sizes of this model.
For Black Friday, Best Buy has an exclusive 55-inch variant, the UN55KU6270 (UN55KU6270FXZA). We expect it to have the same picture quality as the KU6300 reviewed, but like the other cheaper variant, the KU6290, to only have a standard remote and no Bluetooth connectivity.
If someone comes across a different type of panel or if their Samsung KU6300 doesn't correspond to our review, let us know and we will update the review.

Compared to other TVs
Top left:: LG UH7700 (55UH7700). Bottom left: Samsung KS8000 (UN55KS8000). Middle: Samsung KU6300 (UN55KU63000). Top right: Vizio D 4k 2016 (D50u-D1). Bottom right: TCL US5800 (55US5800). Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.
The Samsung KU6300 has fierce competition in the budget range. It is a good choice if you want an affordable versatile TV.
Vizio D Series 4k 2016
40" 50" 55" 58" 65"
The Vizio D Series 4k 2016 is similar to the Samsung KU6300 but with a few key differences. It doesn't support HDR, has somewhat worse upscaling but offers local dimming and better motion. For high quality content, its picture quality is slightly better. Since it is sold for cheaper, most people should buy the Vizio D 4k 2016 except for those who watch a lot of low quality content like DVDs and cable TV.
Samsung JU6500
40" 48" 50" 55" 60" 65" 75"
Last year Samsung JU6500 shares lot of similarities with the KU6300. It doesn't support HDR and isn't as good for watching movies but it has slightly less blur which makes it a better option for sports.
Samsung KS8000
49" 55" 60" 65"
The Samsung KS8000 is definitely not in the same price range of the KU6300 and it shows. Its picture quality is way better no matter the content. It can get extra bright too so a better fit for the living room. If you have the money, don't hesitate to get the KS8000.
LG UH7700
55" 60" 65"
The LG UH7700 is also more expensive than the Samsung KU6300 but not always better. It is when the TV is viewed from the side but not from directly in front in a dark room. It is better suited for a wide living room with seating on the sides than for watching late night movies.

I don't understand your ratings system. Every single review and customer rating I've been reading has been overwhelmingly positive, but your rating almost treats it like it's a piece of garbage. I was so excited when this new affordable Samsung 4K television came out I was almost headed out the door to purchase it, but upon reading your review, I am now back to my search again; I'm wondering who's correct. Amazon's customer reviews are almost all 5 stars, with most raving about the great picture and features, yet you give it a 6.9. What gives?
On Amazon, products that have great value for the money gets a lot of positive feedbacks and the KU6300 is one of those product. Also, usually people who spend less on a product have lower expectations. We don't factor in the price in our reviews so our score is only representative of the TV performance. This way, the score can be compared to higher end TVs.

Best Buy has the Samsung UN55KU6290FXZA on sale for $699 thy also have the UN55KU6300 for $200 more what is the difference and which would be the better TV to buy?
They appear to be very similar. The KU6290 is a Best Buy exclusive model, which is missing bluetooth and has a standard remote instead of the smart remote. Save the money and go with the KU6290.

Overall, the Sony X900C is better, mainly because it is a higher end TV with more features (like wide color gamut, 120Hz, better viewing angle, etc). But directly in front and in the dark, the Samsung has a better picture quality.

Greetings, I'm curious as to the input lag on this display when set to PC mode instead of Game mode as I'd plan to use this for both general PC usage and PC gaming.
When set to PC mode, the input lag is 36.7ms. This should not be an issue for most people but serious gamers should change the input to 'Game Console', even when playing PC games. The advantage of PC mode is the chroma 4:4:4 support, so if this is not necessary for you then you can use 'Game Console' all the time.

Your Samsung KU6300 review was just what I've been waiting for. Looks like in choosing between last year's Samsung 40" J6300 and the new KU6300 - last year's model might be better. Although it's not 4k - when sitting further than 6' away - does that make ANY difference at all? At what distance will 4K begin to positively impact colours or picture sharpness? TV is mainly for "living room" use (in a bedroom), movies streaming, no gaming but unfortunately - viewed from a slight angle.
For a 40" TV you may just be able to see the benefits of 4K from a distance of 6'. For that size, it is generally noticeable from a distance of about 5'. The viewing angles of both TVs are similar, go with the J6300.

I bought UN55KU6300FXZA from Bestbuy on prime day price match guarantee. We watched couple of movies we did like the picture quality. But having difficulty to watch sports. Whenever we try to watch sports we feel sports picture quality is not good. It's so blurry when we try to watch sports. We have X1 box from Comcast Xfinity. I heard Comcast is coming up with 4k picture quality in couple of months. Since we watch lot of sports channels, we are still debating whether we should return this TV or keep it . Any recommendation for nice TV to watch sports and movies? Okay with LG, Samsung and Vizio.
First you could try our settings here. Try with 'Auto Motions Plus' set at Off. If still not good, you can try to set it at custom and set low value like 3 or 4 for and 'Judder Reduction' and leaving 'LED Clear Motion' off.
If you are still not satisfied and want to change for another TV, the Vizio M series 2016 as an edge for sport and image quality for movie is also very good. It is a little bit less good at handling lower resolution content, but if you upgrade for an 4k cable box, you should be good.

So I just bought the KU6300 50inch Samsung. It has HDR PRO. I hook it up to my PS4 on HDMI port 1 and then I switch into GAME mode. After switching, I try to enable HDR and it states that this function is not available. Was wondering if I'm doing something wrong and how you got those settings for the input lag tests.
First you have to set 'HDMI UHD Color' 'on' for the HDMI port 1, from the picture 'Expert Settings' page. Once this is done, with this TV you don't need to turn on any special mode to get HDR to work, since when the TV detect and HDR signal, a popup is going to appear telling you that an HDR video is playing. It must not be confuse with 'HDR+ Mode' from the 'Special Viewing Mode', which is a 'Fake HDR' that will transform normal content to make it look like HDR.

I bought the 40" KU6300 today after finding this site yesterday. I love this as a monitor. When I try to enable UHD color for the HDMI to the PC it doesn't appear to see the PC input anymore. Works great with it turned off but I was wondering what's happening there and am I not getting the best picture as a monitor then?
It may be an issue with your HDMI cable. Due to the high bandwidth of a 4k 60Hz signal, you need a full speed cable for the UHD color information. Cables that are very long (>20') may also have an issue with the bandwidth requirements. UHD color can increase the definition of text.

After I sent my J6300 into geek squad to fix the backlight bleed, it came back to Best Buy with the screen cracked due to mishandling from transportation. As a result, Best Buy junked the old model and graciously swapped it for the KU6300 for the same price as the J6300. That being said, I was sceptical after reading your review and thought I was getting a weaker TV. However, I actually really like this model a lot. I know you've mentioned the judder issue in your review, but I'm not having that problem whatsoever (especially with blu rays). Plus, both the color and blacks are great, albeit the color could be slightly adjusted. Nonetheless, so far I've had great movie watching experiences with this TV and find it rather difficult to believe that this particular model received a less than stellar score in movie usage. Could it be your team received a crappier set?
We buy all of our TVs through retail channels. This means we expect the reviews to be representative of the typical TV you might buy in a store. There is always some variance in the quality of each TV, however this mostly affects the uniformity and white/color balance. The rating of the KU6300 is quite good, especially considering the price which does not affect the scoring. Most of what brought the KU6300 down was the lack of features available on more expensive TVs, such as local dimming. This does help to improve the movie watching experience and so affects the score. Judder does not depend on the individual TV but is not noticeable for most people and so only makes up <5% of the 'Movies & TV' score.

Amazon.com currently has deals for prime day on the Samsung UN55KU6300 and the UN55KU6600. Are they the same except for the curve?
Yes, the Samsung UN55KU6600 is a curved UN55KU6300. The picture quality should be in the same ballpark, and since the curve is not really worth it, get the cheaper UN55KU6300 instead.

What is the input lag when in 4:4:4 mode with 4k at 60hz, while in game mode (if possible)?
Game mode doesn't support 4:4:4, only PC mode does. The input lag at 4k @ 60Hz @ 4:4:4 is 36.7ms

I just got the KU6300. It looks great, and followed your recommended calibration settings. However, I cannot get rid of some type of auto-dimming. When the scene goes primarily dark, white text dims quite a bit too. It's pretty obvious if you have some video playing while the TV's menu (white text) is open. I've disabled energy settings, dynamic contrast, and other things, but it persists. I have read elsewhere on the internet that you can disable auto-dimming ONLY in the service menu. On your calibration page Q&A, you talk about entering a service menu.
So, I suppose I have 2 questions:
1. Is there indeed, a way to turn that off, via the service menu?
2. Since a normal samsung remote is required to get to it, what remote did you use? What should I buy so I can access the menu?
If I can fix this with a service menu tweak, great. If not, I might need to return this TV. It's really annoying to me. Thanks.
There are two ways to disable this. The first is with the picture mode. 'Movie' reduces the effect and 'PC' removes it completely (but reduces calibration options and disables some settings).
The other option is a bit more difficult. Increasing the brightness (to around 55) and then counteracting this increase with the 2 point offset will disable this dimming. This requires recalibrating the TV with the higher brightness and 2 point red, green and blue offset.
On the KU6300 the option is no longer in the service menu.

According to Samsungs website, this TV has local dimming, it is something they could of added with a firmware update?
No, local dimming is a hardware option, so it can't be added via software update.

I live in Mexico and there's a TV for sale in a mexican market website model UN40KU6000FXZX, is it the same model as the KU6300, I've read in a website that is the same model number in the UK, but the letters UE change to UN but the model number 6000 is the same in Mexico. Also, the specifications are the same. I'm interested in buying this model but I want to know if it's the same here in Mexico (KU6000) as in the US (KU6300).
The UN40KU6000FXZX in Mexico appears to be the same as the UN40KU6300 in the US.

For 4k TVs that do not have the wide color gamut, if all else is very similar, is HDR even recommended as a consideration given the lower price of a non-HDR 4k or even a 1080 TV? For the same TVs, is there any way future firmware updates could improve the HDR picture quality of a low color gamut TV? I don't want to abandon the idea of HDR on a set that does not have a wide color gamut if this is something that can be improved upon sometime in the future. I also don't want to pay extra for HDR-capability on a low color gamut set if its not useful.
Unfortunately, wide color gamut cannot be upgraded via an firmware update, since it is related to the construction of the TV panel itself. For the moment, HDR is still in it infancy and "good HDR performance" is really a high end TV feature. For mid range and budget TVs, HDR is more marketing than a real upgrade in performance. You may have more for your money with a very good SDR TV than an bad HDR TV.

Wondering if the KU6300 65" will be an overall good TV for my apartment. Will be watching Blu-Rays and playing video games in the dark primarily, but sometimes during the day. There won't be any windows pointed directly at the TV either, only one from the side. Just looking for the best 65" TV for around $1500.
The KU6300 is a good pick, turn on Game Mode from the 'Special viewing modes' setting to reduce input lag. The video quality is good for movies, and the brightness level should have no issue with the side window.

I purchased this 40 inch version of this TV at a local store for a very reasonable price, and I am using it as a 4K PC monitor based your input lag data. I have noticed that this monitor produces some very powerful color levels/brightness when things like lens flare and ambient occlusion are switched on in some games. In fact, this monitor greatly outperforms my LG 34" Ultrawide (non 4K model) in this respect. Is this the result of some effect from the HDR support, or is it just a property of a VA panel? I know you stated that HDR support does nothing on this set, but it seems like brightness, contrast, and color intensity are stronger on this TV than other LCDs I have used.
Basically, this is not a result of the HDR support but due to good SDR support. The VA panel results in a contrast ratio which is quite a lot better than any IPS panel we have seen. Although the KU6300 is far off the HDR standard of 1000 nits, if you look at our comparison table of peak brightness here you can see it is better than the majority of TVs. This increased brightness helps to define highlights and makes the colors appear more intense even though it only supports a SDR color gamut.

After going back and forth between this review and the review of the Vizio 4K D series, I seem to be at a bit of quandary with the HDR aspect of both sets. As you stated in the introduction of your review, "It supports an HDR input, but it doesn't have the capabilities to display a more colorful picture." To me, this means it'll play HDR content and display bright whites and deep blacks fine but won't benefit from the color aspect like a good HDR TV would due to its lack of WCG and 8 bit panel. However, you state in the HDR format portion of the review that it supports HDR 10 but won't benefit from it. Now, if you were to juxtapose the KU6300 against the Vizio 4k D series, which TV would benefit more with HDR content?
For HDR content the TVs are very similar, but the KU6300 is a slightly better choice. Both TVs don't support a wide color gamut, but the KU6300 does get slightly more bright. The Vizio D 4k doesn't support any HDR formats, unlike the KU6300 which supports HDR10 content. The picture quality of both TVs are also similar, however the Vizio D 4k's picture quality degrades slightly more rapidly when viewed at an angle.

I suffer from what seems to me as a Hz problem. Often, irrespective of the content (1080p or 4k) when I set auto motion plus to maximum, I notice patches of frames or misplaced frames during fast moving content. During still camera or slow camera pans, I enjoy the continuous motion and is very life like. But as I mentioned earlier, during fast action sequences this thing struggles to put the frames together and the resulting picture is patchy. Specifically, when I try to play this 'judder test video' from Youtube, I notice patches everywhere. Is this because of the 60z panel and Samsung trying to upscale it to 120 or just my TV? I really enjoy the soap opera effect and I prefer watching content that way. But this TV is killing the experience for me introducing patches and misplaced frames.
Soap opera effect will always introduce some interpolation artifacts. Diminishing it will reduce the interpolation artifacts. In the end, try to find a setting that is best for you.

Do you guys plan to review those Hisense 4K TVs? Specifically the Hisense 43H7C. Interested to how that compares to this Samsung KU6300. You guys are only ones that break down everything, so if it has good motion processing unlike the KU6300 for movies, I'd be interested to see your take on this on other aspects and how it handles.
Unfortunately we don't have plans to review that model at the moment, but may do so if there is sufficient demand. We do plan to review the H8C within the next month, which may give some idea of how the H7C may perform.

I'm stuck deciding between the Samsung KU6300 and LG Electronics 65UH6150. Which one has better features, app options, and better picture quality?
We haven't reviewed the UH6150, but expect it to be very similar to the UH6100. The KU6300 has better picture quality in a dark room, and from directly in front, however it degrades rapidly when viewed at an angle. The UH6150 has worse picture quality from in front but is retained better at an angle. Unless you have wide seating, go with the Samsung KU6300.

Great site. I am sure you have helped numerous people with TV purchases. You are helping me make up my mind for my next set. Anyways, I purchased a 4K Samsung 40" KU6300. When I am in Amazon instant video app, watching Interstellar (not 4K UHD), the picture seems to be stretched, up and down, about 10% give or take. Just enough to notice something is not correct, visually. Basically it is not to scale as it is on my 2 other Samsung TV's (not 4k). Yes, I have checked to make sure all the aspect ratios and picture size settings are correct. Have you ever run into this or heard of this? Can it be a faulty TV? I have noticed it on one other movie through Amazon Prime, but not all movies, which is weird. Thanks for the great reviews.
Any help or info is appreciated.
We have heard about this on various devices, and it seems to be a bug with the Amazon app. Unfortunately we don't know if or when this will be fixed. One workaround is to use an external streaming box, but this is obviously far from an ideal option.

I just purchased the KU6300 from Best Buy and game mode does not work in 1080p at 60 Hz. It is only available in 1080i at 30 Hz. Your review states that game mode is available at 1080p, but this does not seem to be the case. Could I be doing something wrong?
Game mode works in 1080p@60. If you are using a PC, make sure you tag the input on the TV to Blu-ray to disable PC mode. Otherwise, PC mode is automatically engaged on 60Hz signals.

I live in Brasil, and here there's a Tv 40KU6000, and 40KU6300. This KU6300 is curved. I wonder if this KU6000 is same as the TV you used for the review.

Your review of the KU6300 shows that it doesn’t handle judder well (“can't remove judder from any movie source”). In your “settings” for this set you seem to be saying judder can indeed be controlled through Auto Motion Plus (best set to low values). Furthermore, does this TV have a custom judder setting like other Samsung's?
There is a custom "Auto Motion Plus" setting which allows changing the "Judder Reduction" and "LED Clear Motion" values. Regardless of the values set, judder cannot be completely removed.

I purchased the Sony 810 and found out the hard way that Amazon video does not broadcast in 5.1. It only will do stereo. I'm very tempted to buy the Samsung 6300(2016) 55 inch. My question is, does Amazon video broadcast in 5.1 on it? Netflix was fine.

This answer is at odds with Samsung's website, that describes the KU6300 as have "UHD dimming". Or is this different than the local dimming you are discussing here?
UHD dimming is different to local dimming, and can be slightly misleading. UHD dimming adjusts the contrast of different areas of the picture to try to enhance highlights. As we aim for a true-to-source image, we try to disable this type of processing. Local dimming adjusts the backlight in different areas to produce an image closer to the source.

Hi there, I'm just a tad confused about HDR. Is this or is this not a good HDR TV for gaming consoles? You mention KU6300 lack wide color gamut but then say it's suitable. Thanks.
The KU6300 is suitable for HDR gaming because it has a good input lag under this specific condition, compare to other HDR TVs that have a much more important input lag with HDR. That said, you won't have all the benefit of the HDR compare to, let say the KS8000, that have a wide color gamut. You will still have some benefits, but not just the full range of colors.

You will get better color reproduction with the 43" Sony X800D since it has a wide color gamut, an option that the Samsung KU6300 don't have. Beside that, both TV are very close in term of other performance. If you can wait until you can afford it, You should not be disappointed.
It is important to note here that the 49" version of the Sony X800D is an IPS TV with a lower contrast ratio that the Samsung KU6300. If you were looking for the 49" X800D, then you should go with the Samsung KU6300, even if it does not have the Wide color gamut feature, since it has a VA panel with a much higher contrast ratio, it will have a much better picture quality in a dark environment like a bedroom.

I have the Samsung UN40KU6300FXZA try to enable HDMI UHD Color on all 3 HDMI port. I am use PC on HDMI 1, PS4 Pro on HDMI 2 and XBOX One S on HDMI 3. HDMI UHD Color is just enable in port 1. Why can i not enable the other 2 ports?
Only the HDMI port 1 is able to support the full HDMI 2.0 bandwidth on this TV unfortunately. The 2 other port are not full bandwidth compliant. Maybe this decision was made to be able to cut the price of the TV, since the more expensive KS Series support the full bandwidth on all HDMI port.

Can you go over the benefits of HDR when WCG, 10bit and Brightness is missing?
Basically, there will be no benefits to the picture quality over a SDR 4k signal as it will still display the image in the Rec 709 color space, in 8 bit, and with normal luminosity. The UHD Blu-ray player will convert the HDR gamma curve to a SDR gamma curve.

I'm torn between buying a newer "K" series set, and last years "J" series sets which are being heavily discounted everywhere right now. The price delta is HUGE, and I was wondering if HDR and few other picture refinements are really worth the $1500-$2000 difference in price. It's a tough call. I always want the latest and greatest technology available, but is there really that big a difference in overall picture quality between the two series?(JS9500 vs. KS9500)
The biggest differences between the JS9500 and the KS9500 are the maximum brightness which is higher on the KS and the different backlights. The JS9500 has a full array backlight, and the KS9500 is edge lit. This results in better local dimming for the JS9500. The other differences are very minor, and it probably isn't worth the big price difference for you.

I see Costco has the UN70KU630DFXZA on sale for $1650. How is this different from the one reviewed? The specs say the VESA connector is TBD. Does it have one, and can it be wall mounted with a standard kit?
The KU630D is likely to be very similar to the KU6300. It also likely has a VESA 400x400 mount but we can't find any reliable information on that at the moment.

We haven't reviewed the UH6350 and so can't comment on it. The UN70KU630DFXZA is the warehouse version of the KU6300 and should offer the same picture quality. The Vizio M Series is an overall improvement on the E Series 4k. For watching lower quality content such as cable, the upscaling of the KU6300 is better. Also if you use it as a PC monitor, the KU630D displays text more clearly. For other uses go with the Vizio M Series 2016 as it offers slightly better picture quality, especially in a dark room due to the local dimming feature.

I JUST purchased the UN55KU630 Samsung 55" TV. The price was affordable at about $875 which included an extended 3 year warranty at Costco. However, after reading so much on here, I'm wondering, did I make the best decision. I watch A lot of TV, and I'm wondering if this new TV will be better quality than the one I had previously which is a Samsung model LN46C63OK1FXZA. I'm just curious, will the new one, be a much better TV. This one, has finally seen the end of good quality. Also, I was told the new TV I just purchased has a refresh rate of 120. The info I read says no.
The Samsung KU6300 (or KU630D from Costco) is a good TV and one that is recommended in our $750 to $1,000 category. It will have many new features that were not available before, so it is a bit hard to compare with your older TV.
Often the refresh rate that is advertised is more a marketing gimmick than what it is really (see our article about it here. When we do our review, we test to determine the real refresh rate. That why in that case, Samsung advertise it as a 120Hz TV when in fact is a 60Hz TV. But you should not be worry about this, unless you really want to have the 'Soap Opera Effect'.

I notice in the 'In the box' picture there is "Audio Out Adapter" does that mean I use that to hook up to my wireless headphone transmitter??
Thank you for pointing this out, it is an error in the text and has been updated. Depending on how your wireless headphones work, it is possible to either connect them via Bluetooth (built into the TV), or with the optical out connection. The RCA adapter in the box is just for audio input into the TV, as the TV does not support analog audio output.

Hi, what are the differences between this model and EU KU6000? Will there be a difference in image quality?
There is no difference. The KU6000 is the European version of this TV and you can expect the same performance.

Hi, I plan to connect my PC to a TV and mostly use it for gaming. I have a radeon R9 Fury X graphics card, as its not enough to run say the witcher 3 at 4k with high settings, but it can run the game well at 1440p. Can I set my game to 1440p and will the TV upscale to 4k? If so, should I set my desktop resolution to 1440p as well, or is running the game at 1440p in fullscreen mode enough? I really curious about how exactly does the upscaling works. Also, if I play a 1080p video on VLC, will the TV upscaler help me or should I mess with the settings somewhere ? I'm looking for a TV with good upscaling and I dont want to spend more than 700 dollars. I really appreciate your great reviews and looking forward to that Hisense TV review you guys have planned! Keep up the amazing work!
1440p works on that TV, and yes it upscales to 4k (every input always get upscaled) but keep in mind upscaling doesn't improve the picture in general. Whether the TV upscales 1080p better than VLC is a bit of a personal preference, especially since with plugins VLC can be tweaked a lot.

My parents live in rural area and have 6 Meg Internet and DirecTV Genie receiver. They also have a Panasonic Blu-ray Player. They use this for Amazon and Netflix. Currently they have a Panasonic 58 inch plasma. Looking to buy them TV for retirement celebration. Want to get them a Samsung television from Costco as I think Vizio's Smartcast would be confusing and their internet speed isn't great. My question is: For such a simple setup... Would you recommend the KS8000 or the KU6300? Exactly how bad is the motion blur on the KU6300? I don't want to overspend if we don't have to. But I do want to get them something good. We plan to mount it on the wall. Thanks!

I looking for a TV around the $500 to $1000 range, I will mostly be interested in watching/streaming movies. Also would like to have a good sound system included.
Samsung KU6300 & Sony 55X700D are a few options in that list. Can you please recommend best option among these two or you can also recommend if any other model is good.
Also I would be keeping this in a living room and viewing at a distance of 10 to 12 feet. Would you recommend 50 inch or 55 inch?
Thanks in advance.
At a distance of 10-12' you generally want to go for the largest size you are comfortable with, to improve your field of view and the resulting picture quality. We don't recommend choosing a TV for the sound system, as they are generally all much worse than any external speakers or soundbar. If you care about sound, it is better to reduce your TV budget and spend the excess on a cheap soundbar. The 55" Sony X700D sounds like the best choice for your situation. The native contrast ratio isn't as good as the Samsung KU6300, but the whole screen gets bright to combat glare and reflections in a brighter living room. The picture quality also remains good when viewed at a wide angle.

I am looking for a decent HDTV as a Christmas gift and this one seems pretty good for price/performance ratio. I just don't understand why such a critical item like movies have judder? Does Samsung think it is not important or negligible? Does this HDTV have judder for all sources?
Most people don't notice it, so it may not be seen as a priority. On the KU6300 movies played from all sources have 3:2 pulldown judder.

Hi, I was just wondering if the KU6300 Could potentially receive a software update that would widen its color gamut and would that actually improve HDR10 functionality? How would I know? Also, how much better is the Sony X800D in regard to HDR quality. I'm wondering if I should keep my Samsung or return it and get the Sony. Thanks.
The wide color gamut feature can't be added via firmware update, since this is a hardware related feature. The only big difference that you will notice is the color that are going to be more saturated because of the wide color gamut and there should also be less banding since it has a better 10 bit panel.
Note that the 49" version of the Sony X800D is using an IPS panel that has a lower contrast ratio that the VA panel use in the 43" version. In that case, we would recommend the Samsung KU6300 over the 49" Sony X800D.

Hi, I have three flat screens in mind, which one is best for general viewing, my choices are: the Vizio D65U-D2, the Samsung UN65KU6300 and the SONY XBR65X750D.
Depending of your room set-up and lightning the best TV will not be the same. If you will sit most of the time in front of the TV and the room will be relatively dark during your TV viewing time, go with the Samsung KU6300. If you will not sit in front all the time and your room will be well lit, then go with the Sony X750D.

Hi, do you know if this set can display 2560x1440 QHD resolution from a PC? If so how well does it handle the scaling, and what is the input lag in this mode? Does it require setting up custom resolutions in the GPU driver? Ideally I would want to use 4k when on the desktop but drop down to QHD @ 60Hz when gaming so my GPU can keep up. I have a GTX 1070 which is fine for 1440p but too slow for native 4k. Thanks!
Yes you can (without custom resolution), but it is a bit fuzzy since the ratio doesn't convert as well as 1080p on a 4k screen. We aren't able to measure input lag in that resolution currently unfortunately.

I just bought a 6290 and it comes with a smart remote and appears to have a full browser (some sites report it has a reduced function version). However, while the Samsung web site says bluetooth is supported on the 6290, you are correct - it's not. I confirmed this with Samsung tech support yesterday and they'll be updating the site. Best Buy swapped the unit for a 6300 because of the spec error.
Thank you for this extra information.

What are your thoughts on build quality? There are user reviews on Amazon and Target that state the screen breaks easily (hand pressure)?
We haven't noticed any issues for build quality of the KU6300, and we move our TVs around a lot. For the average person who leaves their TV in one place there should be no issues.

I'm thinking of buying a Samsung 50KU6300 on Black Friday but noticed that it has a smart remote instead of a standard remote. What are the pro's and con's with the smart remote if I use the TV 95% of the time just for watching regular TV?
In general, the disadvantage of a smart remote is that it may not be as intuitive to use. This isn't the case of the KU6300 smart remote which is quite minimal and provides easy access to all of the functions. If you wish to enter channel numbers it is a bit more difficult as you need to use an on-screen keypad. If you wish to use a more traditional remote you can also use any universal remote. Overall the smart remote is an improvement, even for watching regular TV. It connects via Bluetooth for most functions so it doesn't always need to be pointed at the TV.

What's a better buy, the TCL 55US5800 or Samsung UN55KU6300? Does TCL 55US5800 use a VA panel, and if so do you know the contrast ratio?
The 55US5800 is currently being reviewed, and will be posted this week. It uses a VA panel and the contrast ratio is 3504:1. The KU6300 is a much better TV.

I just got the TV and love it. Is 4K upscaling ON by default?? I cannot find anywhere in the settings where to turn ON/OFF 4k upscaling.
There is no option to turn on or off upscaling. The TV has a 4k resolution, so any time there is a source with lower resolution it will be scaled to fit the KU6300's screen.

What was the reason for that big dip in gamma around 80-90 IRE in the precalibration measurment? Was an energy saving setting on by default in movie mode?
We disable all energy saving features before performing the pre calibration measurement. This is just due to the way the TV is calibrated initially. Other Samsung TVs have similar results, such as the KS8500 which has a very similar pre calibration white balance and gamma curve. It is also seen to a lesser extent in the KS8000 and KS9500 prior to calibration.

First off, I wanted to thank you for all the time and research you provide. I’ve turned everyone onto your reviews, as it’s super helpful! My 46” LG has left me and died right at 10yrs, so I’m looking for a replacement TV. My viewing isn’t crazy, I rely heavily on cable TV and the occasional Roku stick binge. My living room isn’t too bright and my TV is about 6 feet away from couch, no angle viewing and I like to have the lights on when viewing TV. Should I get a top model 1080 or a 4K? If 1080p, what model and size would you recommend? If 4k, would you recommend the Samsung KU6300 @ 50” or the Sony X800D at 49”. I do like a more realistic viewing, so is the Sony worth $250 more? Also, should I be aware of any panel lotteries on these two, as I’m a little nervous because some Amazon reviews were very mixed on the Samsung KU6300 & the price keeps dropping. Should I buy a certain “letter” version? Also, open to another 4k option under $850 between 48” – 55”, as Best Buy recommended the Insignia/Roku 4k model 50DR710NA17 @ $450, but your reviews aren’t the best for that model. Goal is a crisp view, viewed comfortably from my couch. Thank you for your time in advance.
Go with a 4k TV if you want the sharpest and crispest image quality. In the 4k TVs, for your use and price range, both the Sony X800D and Samsung KU6300 are good choice. If you want the superior TV (by just a bit) go with the Sony 49" X800D. If you want to save a bit of money go with the 50" Samsung KU6300 or if you want to spend the same amount but have a bigger TV, then go with the Samsung 55" KU6300.
