The Samsung KS9000 4k UHD LED TV has a lot to offer. The picture quality is excellent and it handles most content nicely. With the fact it can get very bright and doesn't have much reflections, it is also a good fit for even the brightest living room. Unfortunately, it isn't perfect. Its picture quality diminishes when viewed from the side.

Samsung KS9000 Design Picture
Curved : No

The Samsung KS9000 pleases the eyes with its high end look and thinness. The materials it's made of all seems to be of high quality. From its chrome stand to its thin metal borders and even its textured back, this TV is sure to look great in any room. It has the same overall look as the Samsung KS9500 minus the curved screen.

Stand
Samsung KS9000 Stand Picture

The stand of the TV has a nice chrome finish. It has a fairly large footprint and goes a long way toward the back of the TV. It could not be ideal if you want the TV to lay against a wall.

Footprint of the 55" TV stand: 33.9" x 15"

Back

Wall Mount : Vesa 400x400

Even the back of the TV is both sleek and attractive with its textured finish. A cover that is included with the TV hides the back inputs that won't be in the way to wall mount the TV.

Borders

Borders : 0.39" (1 cm)

The borders of the TV are thin and have a nice metal polish to them.

It is reported that the 75" variant of this TV has thicker borders.

Thickness

Max Thickness : 1" (2.6 cm)

Very thin from a 90 degree angle. The bottom part of the TV is thicker. The maximum thickness measurement include the horizontal metal looking plastic border that goes across the back of the TV.

Picture Quality

The Samsung KS9000 provides excellent picture quality. Colors really pop, details are plentiful and highlights are very bright. This stay true whatever the sources, even for low quality content like cable TV and DVDs. It gets even better on high quality content like blu-rays and 4k materials. The KS9000 is able to produce beautiful scenery even on very dark content. It gets very bright and handles reflections well.

The local dimming feature on the KS9000 doesn't work very well. It does darken the blacks but some small highlights too like the dot in our test video. Although it isn't that much apparent in the video, local dimming sometimes creates big vertical blooming areas on big highlights depending on the scenes. It is more noticeable in person. For this test, we set local dimming ('Smart LED') to 'High'. A TV with a full array backlight can produce much better results.

Very impressive and similar results to the Samsung KS9500. Highlights can get extremely bright and as a whole the screen can also maintain a high level of brightness. As the KS9500, brightness vary on a static screen but is not a problem on regular content. On the downside, very bright highlights can create big blooming areas. We used local dimming ('Smart LED') set to 'High' to get as high peak brightness.
Update: Updated with sustained brightness.

Very low 1080p input lag which is great. The responsiveness you get from controller inputs nearly can't be felt. Players that like first person shooter, racing or combat games will like gaming on the KS9000. Unfortunately, motion interpolation ('Auto Motion Plus') bring the input lag too high to consider using that option. When sending and HDR signal at 1080p resolution under game mode, the input lag is 22.6ms.

Smart OS : Tizen (2016)

Sporting the new Samsung 2016 smart platform, the Samsung KS9000 offer a good experience with most of the popular apps at the disposal. Menu navigation is straightforward although a remote with a pointer would have helped for text input. The KS9000 offers plenty of inputs, more than enough for most home setups.

When a new device is detected (such as when a computer is woken from sleep while plugged into an HDMI port) the TV automatically switches to this device. This may be an annoyance if you are watching other content at the time.

Bottom right: Samsung KS8000 (UN55KS8000). Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The KS9000 is definitely the best overall LED TV we tested so far for a mixed usage. However, it is priced very high, so we don't really recommend it.

Samsung KS8000
49" 55" 60" 65"

The Samsung KS8000 is a better buy. It is almost as good as the KS9000 on all aspect, it just doesn't get as bright. The price difference is not worth it, so buy the cheaper KS8000.

Samsung KS9500
55" 65"

The pricier Samsung KS9500 has the same picture quality as the KS9000, but with a curved screen. The curve is not worth it (see curved vs flat).

Vizio P Series 2016
50" 55" 65" 75"

The Vizio P has a lot more bang for the buck for a similar picture quality, as long as the content being played is of high quality. For exclusively watching movies in the dark or playing video games, the Vizio P is a smarter buy. For other usage, like sports, cable TV and DVDs, you better buy the Samsung KS9000. In the living room, the Samsung KS9000 is also better.

Sony X930D
55" 65"

The Sony X930D is worse for playing video games. For most other content, the Samsung KS9000 is also slightly better. Even more so when watched under a bright lighting environment or a very dark room. The Samsung KS9000 is a more versatile TV and a better buy.

The new 'Compared to other TVs' section is very helpful and a welcomed addition to your website. Thanks for helping us with these reviews and constantly keeping us updated.

Does the curved screen of the 9500 really have any viewing advantages over the 9000 reviewed here? I prefer flat to curved most of the time. Thanks!
Nothing significant.

I am looking to upgrade my Vizio M 2015 to either the KS8000 or KS9000. Were you guys able to differentiate 'Supreme UHD Dimming' and 'Supreme MR 240' vs regular 'UHD Dimming' and 'MR 240'? The KS8000 looks to be the better value purchase, but I need to make sure that watching fast action in movies and sports isn't going to be an issue which it is on the Vizio.
We made sure to verify that with both TVs connected through a splitter side by side running the same materials and we couldn't point the KS9000 as being better. Local dimming behaved the same on both TVs and motion interpolation had the same kind of artifacts on the same scenes. Motion interpolation did looked a little different on the KS9000 but not to say better. We were expecting to see some differences there but nothing really notable. You won't miss much with the KS8000.

The only major difference between the 2 is the design of the TV itself, the KS9000's construction look better and more high end. As for the picture quality, ours tests results are so close that we recommend the cheaper one, so that you can have more for your money.

Just got my Samsung 65KS9000, HDR mode doesn't seem to work. It's not increasing the backlight to 20. Using the KS8500 I see the HDR video is playing message on the tv but the backlight doesn't change. Ideas?
If the TV says it is receiving HDR, you are fine. You can manually increase the backlight to 20 if you want.

Hey—awesome review! Does this TV support HDR in Game Mode at the same latency? Thinking about HDR games on Xbox One S coming later this year. Thanks!
Yes it does. With the Xbox One S, enable the 'Game' mode and set the color space to 'Native'. The input lag is 22.6ms.

Hi, thanks for the great reviews as always. My question regarding the KS9000 is the overall local dimming settings. This review mentioned that there are large vertical blooming during bright highlights but I'm wondering if the "active LED" settings (low, high or off) did anything to minimize or get rid of the issue? And since the TV has a very good native contrast ratio as you mentioned, can I turn active LED low or even off and still maintain good black levels? Also, is the blooming apparent in HDR mode or just standard viewing? I will be watching mostly non HDR stuff anyways.
The KS9000 has very deep blacks and high native contrast ratio without the use of local dimming so don't worry about turning that feature off. Local dimming set to 'High' produce more blooming. 'Medium', less, and 'Low' even less. This stays true no matter if the content nature is HDR or not. For the TV to achieve very high brightness, local dimming has to be set to 'High'. Try to use 'Low' for non HDR content and 'Medium' or 'High' for when watching HDR. Local dimming set to off is just as good for most content though so it really comes to personal preferences.

First and most important,thanks for all the hard and honest work that goes into each and every review. I am always highly influenced by your reviews and informative articles. I would also like to ask,if there are any plans to review the Hisense 55H9B2 and 65H10B2, anytime soon? These TV sets were released late 2015 early 2016. This probably makes them 2016 contenders. They are also competitively priced for all they have to offer. They already have great customer reviews. I would just prefer an honest and unbiased detailed review that RTINGS provides. Thanks again.
We will start reviewing Hisense later this year, around fall.

I've read that Samsung moved the LED's this year to the top and bottom of the screen on their edge-lit TV's (KS9000) in order to get the 1000 nits required for the HDR standard. Does this cause all the lights to be seen when watching content with black bars at the top and bottom like a wide screen movie (2.35:1) format for example? Thanks.
Yes, the vertical blooming is visible in the black bars when local dimming is enabled, but it is usually not distracting.

Hello, I am looking to go with a 65 inch TV to replace my 2005 Pioneer Elite Plasma 50 inch. It has a very good picture and I am wondering how the 65KS9000 might compare? Thanks, Jeff
The KS9000 has excellent picture quality, including HDR. It will be an overall improvement, however as it uses a different technology (LED vs Plasma) you may notice slightly lower uniformity and viewing angle.

I thought I'd let your readers know: the One Connect cable that comes with the KS series is actually 6 feet, not 9 feet as specified in the Samsung literature. I called Samsung and mentioned the discrepancy and they sent me a 9 foot One Connect cable as a replacement.
Interesting. We just measured the One Connect cable we got with the KS9000 and it is just short of 6'4". Same length as the cable we got with the KS8000. Thank you for letting us know.

I've noticed the 2016 LCD televisions are getting a 10 for black uniformity when there's obvious blotchiness in the photo. Shouldn't a 10 be reserved for OLED televisions like it use to be for plasmas?
Yes, this is a current flaw in our testing (basically, the way we currently calculate standard deviation picks up some noise on the OLED). We will fix it in a few weeks.

I don't like the legs the KS8000 has, is there a way to buy a separate V stand to use on it like the KS9000 has?
Yes, you could buy a third party table top TV stand compatible with the Vesa 400x400 standard. Something like this one could work.

Does the game mode with HDR on in the Samsung KS9000 make the picture darker or not as good as compared to the normal view? My plasma makes the picture quality not very good when in game mode.
Game mode does disable some processing in order to reduce input lag, but we don't find this difference noticeable and the picture quality is still excellent.

I noticed in your 'Compared to Other TVs' section that the photo of 5 televisions may be flawed. The Sony appears to be sitting in very bright light coming from the windows and that would affect how the TV appears to the naked eye. I would suggest trying to keep harsh light like this from hitting any of the TV's.
We agree the picture doesn't do justice to the Sony TV and can't be used to draw any conclusions (we made sure to add a warning about this under the picture). It only serve as an introduction to the comparison section.

Why is the KS8000 rated as a better gaming TV, when this one has a better response time, and less lag input?
The difference in response time and input lag are almost the same, and may be a result of slight variations between panels. The only significant differences are in design and the KS9000 has better speakers. For most people this doesn't justify the price difference between them.

I have read articles about a Back Panel Separation issue with the KS8000. Do you know about this problem and if so, does the KS9000 suffer from the same problem?
The back panel separation issue has been greatly exaggerated. It is present in our KS8000 unit, as shown in our video review. It's only a cosmetic issue, just a small gap visible at the corners. It doesn't affect picture quality. As far as we know the KS9000 does not suffer from the same issue.

Hi, Is there a way to get rid of the top and bottom bars when watching movies filmed in 2.35 aspect ratio on the KS9000? Thanks
To do that, you need to go in 'Picture Size', and then set 'Picture Size' to 'Custom'. After go in 'Zoom/Position' and zoom in until you don't see the black bar anymore. Be warn though, this is just going to stretch and distort the image.

I currently have a 1080p TV with all the surrounding AV gear. It's about 8 years old. To get the best performance out of the KS9000 with 4K UHD, should I also look into replacing the receiver and cables to be compatible with the HDMI2.0 inputs etc.? What other components should be considered to get the best performance out of the TV?
If you stream 4k directly on your TV via streaming app like Netflix, your AV gear should still work good without problem. But if you ever plan on buying a UHD Blu-ray player with UHD Blu-ray movies, you will need to have HDCP 2.2 compliant components throughout your set-up and some high speed HDMI 2.0 cables connecting them, if not the copy protection will unable you to watch 4k UHD Blu-rays.

I noticed you don't have any reviews/preferences for the new update on Samsung televisions (the HDR+ update on the 2016 SUHD). When activated I've noticed my colors change and it doesn't have the "pop" as natural mode. I'm not sure if my settings are correct on my 65KS9000, but could you do an review or hands on with the HDR+ update for the best settings/picture quality? From what Samsung states, it's supposed to make HDR content look better, as well as SDR. When activated on my TV I really don't see improvement.
We don't recommend enabling the HDR+ mode. When applied to HDR content it aims to bring out more details in the shadows, and to make highlights stand out more. We recommend disabling these features to retain the original image, as true to the source as possible.

Hello. First off, excellent website and review videos. You guys do make it easier for people and I like the time you put in explaining your tests and results. My question involves the durability between the Samsung KS9000 stand vs KS8000 stand. Which one is better preventing the TV from being "wobbly"/moving back and forth. I always have a concern in how the stands uphold the TV and both stands seem to have pros and cons. Overall if KS9000 has the better stand would it justify the price? Currently looking at the 49" ks8000 and the 55" KS9000.
Thanks you for the good words. The stand of the KS9000 does feel a bit more stable than the stand of the KS8000, but we don't think it justifies the price difference.

In your Input Lag section it states 4k @ 60Hz + HDR: 20.6 ms. Do I have to put it in Game Mode to reach 20.6ms? Playing with Xbox One S and I would really love to not lose quality by using Game Mode.
Yes. The change in image quality is not noticeable for most people. For 4k @ 60Hz @ HDR outside of game mode the input lag cycles between 65ms and 80ms.

I know the Samsung KS9000 has the advantage in brightness over the Sony 940D but the Sony has full array local dimming instead of the edge lit. So, with HDR and overall picture quality in mind which would be better between the two?
Unfortunately we don't have the X940D to test, but expect it to be like the X930D with better local dimming. The full array backlight of the X940D is likely to give better dark scene performance with less blooming, and so a slightly better HDR and overall picture quality than the KS9000.

I currently have a JS8500 and I'm looking to buy another set and I am looking at the KS9000, 8500, 8000. Sports and video games are key uses of this set and I am wondering about the motion blur. How does the motion blur compare to the JS8500? Is there a noticeable difference between the JS8500 and the KS8500/9000 and the KS8000? I noticed the 8000 is the worst of the 4 so just trying to get an idea of how noticeable any of these differences are and if its worth me making it a major factor. Thanks for your thorough reviews and feedback!
The difference in response time between the JS8500 and the 3 other TVs is under the noticeable difference of 10ms (KS8000 is 6.1ms, KS8500 is 4.0ms and KS9000 is 4.2ms). So it is not worth make the motion blur a factor when it comes to choose between these 3 TVs. The biggest difference is the design and the price. If you really like the more high end look, then go with the KS9000. If you just want to have the best TV for the price, then go with the KS8000.

Okay I have just bought the UN65KS9000 I also bought a Sony STRDN1070 and a Samsung UBD-K8500 and I have dish network streaming 4k. I have all the proper cables coming from the dish and the bluray. My question is this. I have everything running into the Sony then using the ARC to the TV. But the cable running from the ARC is just a regular monster HDMI cable. So am I seeing a true 4k? And if not please tell me your recommended connections. Thank you.
The Sony receiver supports 4k passthrough, so this setup should work well. The quality of the HDMI cable does not matter as long as you are able to get the picture you want to display on the TV without obvious errors. So it sounds like that monster HDMI cable is adequate for your setup.

That said, some other HDMI cables cannot support the full bandwidth they are advertised to, so some High Speed rated cables may not be able to carry video at 4K; they'll show a blank screen or a picture with obvious errors. We have had best results with the Amazon Basics HDMI cables here.

I need your opinion. I bought a 65" OLED B series and it is very good. I have little kids who leave TV paused and watch cartoons a lot. I don't think I need to spend 3K on a family TV when BB has the KS9000 on sale for 2K roughly. I am a movie buff and love the black levels but with the brightness of the KS9000, will my movie experience "suffer" a lot, or will I still enjoy it? I know its hard to answer. I feel that I am spending so much money on my kids when the KS9000 will do the trick.
The KS9000 provides almost as good picture quality as the LG B6. The biggest difference is the much better viewing angle of the B6, which matters when people are sitting to the side of the TV and viewing it on an angle. This may happen when your kids are watching TV. Whether it's worth saving the $1000 is up to you. Also note that the KS8000 has almost identical picture quality as the KS9000 but is often cheaper.

Great review! Very helpful in making my buying decision. Now that I have it set up, I have two questions:

If I use my Xbox One (base model, not S) for both gaming and as my main Blu-ray player, is there any downside to just leaving that HDMI input in Game Mode? Some of your earlier answers indicate that it's an imperceptible difference, but I noticed that some of the picture options are disabled in Game Mode so I'm not sure if the TV is overriding them.

I also noticed that playing a 4K video on Netflix through the TV app made the brightness increase. In your Settings section it sounded like I would need to manually adjust brightness for HDR; was an auto-adjust patched into the TV? Or was changing brightness manually just for playing HDR games but the TV apps adjust themselves?

Leaving that HDMI input in game mode will disable some features, however most of those features are disabled anyway in our recommended settings. The big exception is motion interpolation; if you like using motion interpolation when watching Blu-rays then you cannot be in game mode. When a feature is disabled in game mode it is completely disabled to reduce the input lag that feature added.

When you play HDR content many settings change to what they were the last time you were playing HDR content, and the backlight for HDR content is max by default. Also settings you changed while HDR content was not playing may not be applied for HDR content, which is why we recommend playing HDR content before changing settings to our recommended HDR gaming settings. There is a bug though that when you are in game mode and playing HDR content over HDMI the backlight will not change to max automatically, it'll remain at what it was before; in that case you may need to change it manually.

We are not taking any more questions for this product because we no longer have it in our lab.
