The Samsung JS7000 SUHD TV's picture quality is a mixed bag. It has a great viewing angle and low motion blur. However, it has poor blacks and bad uniformity.
- Great color accuracy at an angle
- Low input lag and motion blur
- Wider color gamut
- No 24p support, which means judder is present while movies are playing.
- Poor contrast ratio
- Poor uniformity
The Samsung JS7000 looks like a mid-range TV. The TV is fairly thin, and the bezel is small.
It wobbles quite a bit, and is made out of plastic.
Dimensions of 55" TV stand: 33" x 13".
1.77" (4.5 cm)
This isn't a good TV for movies. The blacks aren't deep, and there are lots of with the uniformity. If you watch TV in a dark room, this TV won't look very good.
This TV also has judder when playing 24 fps movies, so this isn't the TV to get if you love watching Blu-rays, DVDs, streaming movies, or other 24 fps movies.
The contrast ratio is really poor on this TV. It has an IPS panel, and produces gray blacks. Note that the 50" and 60" models don't have IPS panels and would have better contrast.
Due to the poor blacks, the uniformity in dark scenes is not good. The corners are brighter than the center of the screen.
It is advertised as a full array backlight, but the 'Smart LED' feature is not even in the menu, so it is a probably an error on Samsung's website.
SDR Peak 2% Window
SDR Peak 50% Window
While it doesn't have a lot of DSE, the overall uniformity of solid colors is quite poor. The edges and corners are significantly darker, and you can see a few vertical bands.
IPS (only 55")
The advantage of LCD TVs with a poor contrast ratio like this one is the color accuracy at an angle, which is great. The 50" and 60" models use VA panels and have narrower viewing angle.
Update 01/06/2017: We have changed the methodology of testing. Since this is an old TV which we don't have anymore, we extrapolated the results from 2016 TVs.
The picture quality on lower-resolution content like DVDs or SD channels is not bad.
720p content looks good once upscaled. So cable TV should looks great on this TV.
This TV's 1080p upscaling is as good as it gets.
Native 4k is displayed well without any issues.
When you set 'Colorspace' to 'Native', the coverage of the Rec.2020 increases.
Its semi-gloss screen finish doesn't reflect a lot of light.
The JS7000 can get bright enough for any type of room.
This is quite a good TV for sports. There's barely any blur, so even the fastest movement is going to look great.
There is a lot of patchiness to the look of playing surfaces, though. If that's something that bothers you, another TV would be a better choice.
The motion blur of the JS7000 is great. It has a little bit of overshoot, but overall, it is one of the best LED TVs in terms of minimal motion blur.
PWM Dimming Frequency
Judder-free 24p via 60p
Judder-free 24p via 60i
It doesn't support 24p, so it has the 3:2 pulldown judder in movies. This is a small and consistent judder, so most people don't see it.
Motion Interpolation (30 fps)
Motion Interpolation (60 fps)
For those gamers who want a TV that doesn't lose too much color saturation at a wide angle, this is a great TV to buy. The minimal amount of blur is also really good for gaming, and there's no noticeable delay between making an action in a game and seeing the reaction onscreen. If you play anything that gets competitive, this is a good buy.
1080p With Interpolation
1080p @ 60Hz Outside Game Mode
1080p @ 60Hz @ 4:4:4
The input lag is low when turning on 'Game Mode' under 'System' - 'General'. In conjunction with the low motion blur, it is a great gaming TV.
1080p @ 60Hz @ 4:4:4
For 4k @ 60Hz @ 4:4:4, turn on PC mode as well as UHD Color.

This TV's bass is pretty good, and it's also able to get pretty loud. It's able to produce reasonably accurate sound, for a TV, but only at normal volumes. Louder volumes are less accurate.
There's hardly any distortion at lower volumes, which is great. There's a bit more when it gets louder.

The low-end cut off and loudness are decent for a TV. The frequency response is OK, but gets worse under load. Pumping may be present at higher volumes.
Total Harmonic Distortion
Very good distortion levels under low volumes. Slight increase under maximum load.
Overall, the smart features on the JS7000 are good.
Only a basic remote is included, which isn't great for using the smart features on this TV, especially the built-in web browser.
Power Consumption (Max)
Feature-wise, the Samsung JS7000 is simply a JU6500 but with a wider color gamut. The picture quality is completely different, though. It has less motion blur and a better viewing angle, but worse contrast and uniformity.
Questions & Answers
41 ANSWERED QUESTIONS
Hello. Do you have a review of the Samsung JS7200? I'm interested in this model.
Unfortunately, since that model isn't available in the US, we won't be reviewing it.
Differences between sizes
We reviewed the 55" Samsung UN55JS7000 (panel version: EH01). It has a PLS LCD panel (a sub category of the IPS family), which is why it has poor contrast and good viewing angle. It is the second Samsung that we reviewed with such panel, the first one being the smaller UN32J4000.
The 50" and 60" models use VA panels and are expected to have better contrast ratios and worse viewing angles.
Based upon my research only the 55" model has an IPS panel. The 60" model has a AUO VA panel(MD01) and the 50" model has an Innolux VA panel. A lot of your responses to the questions posted would be in a different light for the other two sizes. If I'm right it sounds like the UN50JS7000
would be my Goldilocks TV!
Yes, it would appear it is the case. We are currently looking into this and will update our review and questions accordingly when we find out. Thank you for the information.
Update: Information have been confirmed. Review and answers have been updated.
I'm not sure if you all got a bad unit or the poor uniformity and judder is just inherent to the 55" model, because I got the 60" and the black levels look really deep (not OLED deep, but still dang good) and really good overall uniformity. The colors really pop! Also, the only "fast action" movie I've watched on it, so far, is Skyfall on Blu-ray, and I didn't notice any judder or motion blur in intense action scenes. Possibly a bad unit?
It's possible that only the 55" is a PLS TV, which would explain why your 60" version has deeper blacks than our TV. The judder should be present on the 60" version, though. You may just not be sensitive to it.
Thanks for writing in with your thoughts. If you want, can you send us a picture of a closeup of the pixels? This will help determine if the 60" is indeed VA or not.
On the review under HDR the web page is saying unavailable. I just want to confirm that this set is HDR compatible like the other Samsung SUHD models.
is compatible in the way that it will display a picture with an HDR signal but since it doesn't have a full array backlight, it won't be able to produce better contrast on different part of the screen. Because of this, it's implementation make our HDR test irrelevant.
Which TV would be a better purchase: the JS7000
or the JU7100
is a better overall TV, especially when sitting in front. The wider color gamut of the JS7000
is nice, but not enough to compensate for the loss of contrast or uniformity. If you sit at an angle though, you will prefer the JS7000 because the colors don't desaturate as much.
I just bought a 60" JS7000
based on the reviews here. This TV loses a TON of color saturation when viewed from any angle other than straight on. I can email a video if someone contacts me.
Coming from an older Panasonic plasma I am feeling underwhelmed with the performance of this unit. It doesn't seem to have constant upscaling, so things seem to pixelate slightly and then click back in so to speak. I watched NFL all afternoon and then TWD this evening. Using your calibration settings the picture was worse than with it on standard movie mode with motion smoothing deactivated. The settings caused the colors to be very washed-out even by my standards, and I don't like vivid mode a bit.
I didn't want to have to spend $2,500 on a TV but that might be what has to happen. Am I wrong?
The 55" we have reviewed has an IPS panel and has a good viewing angle. The 50" and 60" sizes are different and have VA panels that don't offer the same viewing angle performance (but has better contrast).
Upscaling is constant, so the pixelation is more likely because of the quality of the signal. Try enabling 'Digital Clean View' to remove those artifacts.
As for the washed-out colors, we recommend trying out those settings for a couple of days and seeing if you adjust. If not, stick with the standard movie mode you like the look of.
Unfortunately, no LED TV is close to the picture quality of Plasma TVs. If you want something closer, you would need to get an OLED TV.
Do you think the poor uniformity is common to all units, or you just got unlucky with yours?
Most likely common to all of them. IPS panels usually have poor uniformity, like you can see in our past reviews (especially LG TVs).
Is there a noticeable difference between the JS7000
and the JS8500
? I am trying to decide between the two in a 55" size. The JS8500 has amazing black levels (saw at Best Buy), and I was wondering if they were similar in terms of color and blacks (contrast). Thank you!
There's a big difference. The JS7000
is IPS, so it has weaker blacks and a wider viewing angle. It also has judder when playing 24 fps content (Blu-rays, DVDs, streaming movies). For color, it's similar to the JS8500
This seems to be the best set in my budget for gaming; however, is there any additional input lag generated by the TV upscaling to 4k? Or, is 4k upscaling disabled in game mode?
4k TVs upscale everything to 4k. It just makes the image fit the larger resolution, and doesn't add any detail. Our input lag measuring device is 1080p, so the numbers you are getting are accurate for 1080p signals. 4k gaming signals may have a bit more lag.
Any chance of Rtings reviewing a 50" JS7000
or 60" JS7000, presumably with the VA panels as opposed to the low contrast 55" model with the PLS panel here ?
Unfortunately no. We've run into this same situation before with other models, and unfortunately we don't have the resources to do multiple reviews when different sizes have such significant differences - there are still a bunch of models we haven't reviewed at all so they are a higher priority.
I understand you don't have the resources to test multiple panel sizes within a model, but it would be appreciated if you would revise your recommendations for the 50" and 60" VA panel models. Some folks may miss your additional review notes right below it.
I'm thinking they will perform similarly to the JU6500
but with better color performance. The European equivalent is actually a 6 series television - JU6800.
Those sections are being updated today. Thanks for pointing that out.
I just purchased the JS7000
. I'm hearing a barely audible, rapid, and decelerating clicking sound when the TV is shut off. It starts out very fast and then eventually diminishes to nothing after about 30 seconds. Is this a known/normal behavior for this TV?
Yes, it's normal, so nothing to worry about. We checked and it happens with other Samsung TVs as well.
I have a PS4 and will be using if for both gaming and movies since I don't have (nor want to buy) a secondary player. Will I have to change the game mode to off every single time that I want to watch a movie so that I get the best picture, or is there anyway this can be done automatically?
Yes, there is no other way around it if you are using the same device for both usage. You could keep the TV in game mode though even for watching movies, the picture quality isn't really degraded, it is just that more advanced features are not available.
Hi, the review says to get full chroma 444 I have to put TV on pc mode. I have the un55js7000
. I see the UHD color option but no pc mode. Where is the pc mode option? Thanks in advance. BTW I'm running gtx 980 ti, Hdmi 2.0 4k at 60hz to the TV. Just not sure about pc mode setting.
Press 'Inputs', highlight your HDMI, press the down arrow, 'Edit Type' and then select 'PC' from the list.
We don't currently test our TVs for 10 bit capability.
: From what I've read here, both 50" models have VA panels, instead of the IPS type panel on the 55JS7000 reviewed here .
Would the WCG and other specs of the 50JS7000 be worth it over the arguably decent 50JU7100?
The 50JS7000 is actually $200 cheaper here in the US, and they both have VA panels in the 50" size.
I can't figure that pricing, since the 50JS7000 is an entry-level SUHD and the JU7100
is not, but I am wiling to pay $200 for a noticeably better picture - maybe even up to a Sony XBR55X850C
, but this is a small room, with a viewing distance of 7 -8 ft at most, so a 50" model should be fine, but I might get any one of these in a 55" also.
is the better buy. The JS7000
has a 60 hz panel, which means there will be judder on 24p video, and the wide color gamut isn't a benefit for normal content. The JU7100 is 120 hz (which explains the price difference), so you won't have that issue with judder on 24p.
Overall, the JU7100 is the best of the three options you listed, so you should get that.
I recently bought a JS7000
60". While I have been pleasantly surprised with the motion blur and blacks, I noticed one pesky vertical band on the right, about a third of the way toward the middle. I went days without noticing it, but once I watched a football game I saw it every time the camera panned the field, especially on deep passes. It isn't an extreme difference in brightness and it's far less evident from a straight-on angle. I originally observed it while standing off to the right. Is this more or less the norm with LED LCD's, or should I look at a different model?
also has a few vertical bands that can mostly be seen when watching sports. It isn't rare that LED TVs have uniformity issues. If it is really bothering you, you can try to exchange for a different TV but it isn't guaranty that you will have any better.
Just purchased the UN55JS700DFXZA. Would your review be any different for this model?
No. It may have some small variants but you can expect the same picture quality than the JS7000
I recently just purchased the 60" JS7000
during Black Friday week from Best Buy. Although the picture is amazing (coming from a 9 year old 720p Panasonic plasma), I've noticed a few things: black uniformity / flashlighting on only the left side of the screen, cloudiness and a 'dirty' screen (vertical bands) more noticeable on white backgrounds, juddering + roughness (like a poor buffering stream) when Auto Motion Plus is turned on and the sound is just terrible (when Auto Motion Plus is turned off, the judder goes away but the picture isn't as impressive).
So now I notice that the 55" JU7500
is on sale at Best Buy for the same price. You guys rated it better on the uniformity issues. Since the 7000 is only 60hz, is that why I get the judder? Will this be fixed on the 7500 with 120hz? Is it worth it to swap out the TV for the 7500? I'd be losing 5" but I'd like to not spend any more money on a TV but am willing to if it means getting what I want.
We primarily use the TV for broadcast cable, Apple TV, Xbox One and blu-ray movies.
Unfortunately, what you noticed on the JS7000
(judder, uniformity issues and artifacts on Auto Motion Plus) is somewhat common on LED TVs. What you would gain going with the JU7500
is even smoother 'Auto Motion Plus' (still with the occasional glitches), judder-free 24p movies (blu-rays) and probably a little better screen uniformity. If you don't mind the 5" difference, then the JU7500 will be better.
Watching soccer is terrible on this tv. When panning, the black columns that appear are unbearable. It's not as bad for football. Any idea why it's so bad for soccer? There is a sports mode for this tv and the description states it's for watching soccer but it looks horrible in a different way. What comparable TV can I get that's good for watching soccer. Viewing angle isn't a concern. Would a JU6500
The black columns you are referring to is called banding. This is a screen uniformity problem that is always present but is more apparent when watching sports while the camera is panning. It could be more apparent in soccer just because of the way soccer is filmed. Unfortunately, there is no fix for this. A different TV of the same model could be more or less the same. In our reviews, look at the 'Gray Uniformity' test to reveal this kind of problem. Higher end TVs tend to have better screen uniformity but no TVs are perfect. The Samsung JU6500
we tested had better screen uniformity than the JS7000
so you might get lucky by getting this one too.
What is the UHD color setting for on this TV? Is it only used for connecting a PC?
It's for getting 4k @ 60 hz @ chroma 4:4:4 when connecting a PC (use PC mode as well), and also for getting 10-bit color when watching HDR video.
Since the JS7000
is similar to the JU6500
, and given the $500 price difference for the 55" versions, would you recommend the JU6500 as the better value?
It depends. If you want a wide viewing angle and don't mind giving up the deeper blacks you get with the JU6500
, then the JS7000
is the better choice. If you prefer deeper blacks, the JU6500 is the one to buy.
I'm having a hard time picking the best value for a TV. The JS7000
is $1200 and the JU6500
is $950 for the 50" model. Based on your review, do you think it's worth spending $350 for a TV used primarily for streaming movies and light gaming?
Probably not. The main advantages are that the JS7000
has a wide color gamut and minimal blur. The JU6500
doesn't have a lot of blur either, though, and the color gamut difference isn't that important. We would stick with the JU6500.
Would you recommend the Samsung un55ju7100
vs the un55js7000
The 7100 appears to be a better TV for sports and movies.
What is a better tv for watching sports, the js8500
If you are watching alone, you will probably prefer the JS8500
, because it has less uniformity issues which are more apparent in sports. But the JS7000
has better color accuracy at an angle, so if you have a few guests when watching sports events, it is a better choice.
I see a model JS8000 in Best Buy. It seems to have a 120 hz panel, compared to the JS7000
's 60 hz panel. Do you think watching movies with the JS8000 might be better? Or should I stay away, as it looks like a newer model, and with fewer reviews.
The JS8000 does have a 120 hz panel, so it will be better for watching movies, since there won't be judder.
It's a special Black Friday model, which is why it appears newer, and why it has fewer reviews. It should still be a very good choice.
Did you ever find out if the 60 inch JS7000
actually uses VA panels and have a better rating than initially reviewed? I am interested in this model or the xbr850c. Issue is that tv is 600 dollars more. I'm looking for a 60 or 65 inch television 4k.
The 60" version of the JS7000
has a VA panel so it would get a better 'Picture' score with better blacks and contrast. The Sony X850C
should still be better overall, but due to the price difference, if the small judder in movies doesn't bother you, the JS7000 is a good cheaper alternative.
I read on manufacturer's web site that the JS7000
has Bluetooth capability. Yet, the Samsung VG-KBD2500/ZA Bluetooth keyboard does not reflect the JS7000 model number as being compatible with the keyboard. Has anyone tried to use this or another keyboard with the JS7000 model? If so, what was Bluetooth or USB wireless model found to be compatible.
We haven't tried that keyboard, but our Logitech USB wireless keyboard (this one
) works great. Note that some apps, like Youtube, doesn't support a keyboard.
I have read about the Samsung panel lottery. Is there really that much difference between panel versions as a lot of people have stated online? My version is 1H01. Thanks.
There is a lot of discussions online about this but we don't expect the different panels used on a same TV model to be that much different. That said, we will test that in the future for different sizes of the Samsung J6300
. We will post the results under the J6300 review and will do an article on the subject. We should be able to do that sometime in February.
Are we seriously supposed to believe that this TV covers more of the REC.2020 spec than the Samsung JS9500
and the Sony TVs? Why would anyone pay more for those TVs then since that is their HUGE selling point. I think you have an issue with the REC.2020 coverage numbers for this TV. It can possibly be that high(68.637) vs. 68.5069 for the Samsung JS8500
These measurements are very accurate. We are using a 5nm spectrophotometer. Keep in mind that they are all in the same ballpark, and you can practically consider them the same. You won't see the difference between 68.6% and 68.5% coverage of Rec 2020.
I purchased the 55" JS7000
and I have been really disappointed with the black uniformity. It is really noticeable to me when watching movies, so I am planning on returning it. Do you think that I would be happy with the JU6700
? I use the TV mostly for just regular TV, watching sports, and gaming with the occasional Netflix and Redbox movie.
Yes, the JU6700
would be a better choice for what you're looking to do. The JS7000
's IPS panel makes the black uniformity look worse, and the JU6700 doesn't have that problem.
You are so spot on with this review. I wish I had found this before I bought the 55" js7000
. The sales guy sold me on the so called Nano Crystal technology. I will be taking this tv back to Best Buy. May step up to the 7100 however I am thinking of going back to 1080p. Not sure. I did have a question regarding my time warner cable box. It says 480p all of the time. Does that mean I need to upgrade it. This newer tv actually loses source all the time.
It sounds like there is a problem with the cable box. Make sure you are using an HDMI cable. Also try with a different cable and see if you still loses the signal. If all you get from the cable box is 480p, make sure to select an HD channel (your cable plan must include HD) and that the cable box is setup properly to output HD resolutions. If needed, your cable provider will be able to help with that. At that size, 4k is only worth it if you sit closer than about 8 feet from the TV. If you decide to go with a 1080p, the J6300
is one of the best.
Thanks for your replies here. I thought that might be a difficulty reviewing all the different sizes of a model series that may have different panels since you actually purchase sets reviewed in the field rather than accept submitted sets from the manufacturers that may be ringers and or specially prepared.
It looks like the Ju7100
vs the Js7000
gets down to the panel type and 60 vs 120 hz panel
and entry level SUHD WCG or no and of course most importantly contrast and black levels.
Would a 265.0 cd/m2 max brightness on the Sony X810C
vs ~ 320 cdm/2 on the JU 7100 be a significantly noticeable difference in moderate daylight and no direct reflections keeping in mind the average setting will likely be significantly less?
The Sony X810C high contrast level is compelling to me. I have a Sony 40R450a
with similar contrast it makes a good picture and decent black /shadow detail but could be brighter in daytime.
@ 285.1 cd/m2 was very close to the Sony X810C @ 265.0 cd/m2.
The JU6500 seems plenty bright to me in the store and much brighter than my Sony 40R450A that can only manage 170.5 cd/m2 but as I mentioned earlier the Sony X810C was high up on a wall so couldn't see it straight on and felt I couldn't see how it compared to the JU6500 straight at my viewing distance straight on.
FWIW I'm on my 3rd Sony and they've all been very good sets within their limitations so is the 60" Samsung plasma here.
I'm thinking if the Sony X810C can about match the brightness of the JU6500 in daylight light when calibrated to preference for day in one of the modes for reasonably vibrant colors without gross oversaturation and not wash out it might be fine. The Ju6500 only measured 20 cd/m2 higher at rtings.
Thanks again for your advice. I haven't seen the Ju7100 yet but I intend to.
I've seen the Sony 55x850C, Sony 55X810C and the Samsung JS8500
along with other models of both brands excluding the Ju7100.
FWIW The JS8500 looked better in the store than any of the others including the Sony 55 X850C
but that's a stretch budget wise for me otherwise that would be my choice.
For max luminosity, a difference more than 50 cd/m2 starts to be noticeable, even when the TVs are not side by side. So yes, the JU7100
can get noticeably brighter than the X810C
. But the main difference in a bright room for these two TVs isn't the luminosity, but the reflections. The JU7100 has a glossy screen, which is either good or bad depending on your room. For the X810C vs the JU6500
, they will perform about the same in a bright room.
I want to use a 4k TV for a PC Monitor. Are you sure this will run 4k @ 60Hz @ 4:4:4?
Yes, we're sure. We measured around 44.7 ms of lag in PC mode and with UHD color (necessary for 4k @ 60Hz @ 4:4:4) enabled.
Which is better picture for gaming only, Samsung 55inch JS7000
? Will the IPS panel make a difference with ps4/xbox one games? Which pic looks best in game mode?
will give you a better picture since the 55" JS7000
have an IPS panel that produce weaker blacks and contrast. The difference is visible in all contents including video games, under game mode or not.
I originally fell in love with the JU7100
, but the HDR feature on the 7000 intrigued me. Have you guys since reviewed a 50/60inch 7000?
Seperately, 60hz is way too low. I guess what I'm trying to say is I'm looking for a quality tv with HDR and 120Hz. Am I falling into a trap with marketers proclaiming HDR as the next big thing regardless of the lack of content? Sorry for all of the questions.
No unfortunately. Since there is no local dimming on this TV, HDR isn't expected to be great. HDR will be worth it down the road but as it is right now most of the TVs aren't technically optimized for it (full array backlight with local dimming, deep blacks AND very bright whites). In it's current state, a big part of HDR is marketing but it is expected to become better. Unless you really want to try the latest in technology (and can afford Samsung high end models like the JS9500
), HDR isn't quite there yet.
Do you guys have a good custom calibration for this tv?
Hey guys I just bought the 50 inch js7000
suhd tv. However I have encountered a problem when connecting my laptop via HDMI. I noticed the screen goes black for a few seconds and it does did very often when connected to the laptop. I also have it connected to PS4 and my Direct TV genie and no problems. Do you guys think it's a defective TV? Also why are the HDMI ports in the back have different labels are there any difference between them and if so in what order should I connect my cable box, console, and laptop?
Try to connect your laptop on a different HDMI input on the TV with a different HDMI cable. If the problem persist then the problem lies with the laptop and there is nothing wrong with the TV. If it fixes the problem, try to connect another device in that HDMI port to see if it may be the issue. Some HDMI ports on the TV has additional features like the one labeled 'ARC' that let the sound go through a receiver. For your usage and devices, any HDMI inputs will be fine.
Thank you, I calibrated to your specks for my un60js7000
, I love the picture, my question is: do the rest of the picture modes i.e.: natural, standard and Dynamic setting are calibrated automatically or do I have to do those separate?
You have to do those separately, but it doesn't really make sense to do it because if you copy our settings in another mode, it will make that mode look the same.
I recently purchased the 55 inch js7000
. There is a 2 second sound delay when using the optical out with my Bose sound system. There is no delay when using the TVs own speakers nor when using the Bose system through cable or my Xbox one. Seems to be a problem with the TVs processor as its only when using the smart hub through optical out. Is my TV defective or is the engine that weak that it can't process the sound quickly. The delay occurs over both WiFi and Ethernet. The audio delay is set to 0 all around. Any insight would be appreciated.
2 second is a huge delay for sound. Since the TV audio delay is already set to 0, try a different audio format. Depending on the source, you can select between PCM, Dolby Digital and DTS. Not all may prove problematic. Also, If your Bose system supports it, try to use the ARC connection (HDMI 3) instead of optical. You may have better luck with that.
