This TV was replaced by the Samsung QN90B QLED

The Samsung QN90A QLED is a flagship 4k LED TV. It's part of Samsung's 2021 Neo QLED lineup, which combines Mini LED backlighting with a quantum dot layer to display a wide range of colors at various luminance levels. The Mini LED backlighting helps the TV display deeper blacks as it has greater control over its local dimming feature, and it also gets very bright, enough to combat glare or bring out highlights. It comes with the Tizen smart platform, which is easy-to-use and has a ton of apps available to download, and the new remote has a solar panel in the back, so it uses sunlight to charge. It comes with a bunch of gaming features like variable refresh rate (VRR) support and HDMI 2.1 bandwidth, but only on one port, which is disappointing as you can't take full advantage of two next-gen gaming consoles at the same time.

Our Verdict

Differences Between Sizes And Variants

We tested the 55 inch Samsung QN90A, and for the most part, the review is valid for the 65 inch, 75 inch, 85 inch, and 98 inch variants available in North America. There's a 43 inch variant, but it has a lower refresh rate and doesn't support HDMI 2.1 bandwidth, so it performs differently than the other models. Also, the 50 inch model has the same features but doesn't use the 'Ultra Viewing Angle' technology.

You'll also see it as the Samsung QN9, QN9D, or QN9DA at warehouse retailers like Costco or Sam's Club. Samsung's lineup is different in Europe, so this review isn't valid for the European QN90A, as the European equivalent is the QN94A, while the QN95A in Europe is similar but uses the One Connect Box. Below you can see the full model codes of each model, but keep in mind that the last six letters vary between countries and even different retailers.

Size US Model Short Model Code Refresh Rate Variable Refresh Rate Ultra Viewing Angle
43" QN43QN90AAFXZA QN43QN90A 60Hz No No
50" QN50QN90AAFXZA QN50QN90A 120Hz Yes No
55" QN55QN90AAFXZA QN55QN90A 120Hz Yes Yes
65" QN65QN90AAFXZA QN65QN90A 120Hz Yes Yes
75" QN75QN90AAFXZA QN75QN90A 120Hz Yes Yes
85" QN85QN90AAFXZA QN85QN90A 120Hz Yes Yes
98" QN98QN90AAFXZA QN98QN90A 120Hz Yes Yes

If someone comes across a different type of panel or if their Samsung QN90A doesn't correspond to the review, let us know and we'll update the review. Note that some tests, like gray uniformity, may vary between units.

Our unit of the QN90A was manufactured in February 2021; you can see the label here. You can also see a picture of our service menu here.

Compared To Other TVs

The Samsung QN90A is an excellent all-around TV with exceptional picture quality. It's an improvement over its predecessor, the Samsung Q90/Q90T QLED, mainly because the Mini LED backlighting provides brighter highlights. It's one of the best TVs we tested in 2021, but keep in mind that it's on the costly side, so only get this if you want the best picture quality possible, regardless of the price.

Also see our recommendations for the best Samsung TVs, the best QLED TVs, and the best 4k TVs.

Sony X90J
50" 55" 65" 75"

Overall, the Samsung QN90A QLED is better than the Sony X90J. The Samsung has a much wider color gamut, and it gets a lot brighter, more than enough to deliver a true cinematic HDR experience. It has better viewing angles because it has Samsung's 'Ultra Viewing Angle' layer, but this layer also causes a drop in the contrast ratio. That said, the Samsung's local dimming is significantly more effective at improving the black level. The Samsung has better response times, and unlike the Sony, its Black Frame Insertion feature can flicker at 60Hz in 60 fps content. It has FreeSync VRR support to reduce screen tearing when gaming, and it supports 1440p @ 120Hz on the Xbox Series X, while the Sony can't.

Samsung QN90C/QN90CD QLED
43" 50" 55" 65" 75" 85"

The Samsung QN90A QLED performs better than the Samsung QN90C/QN90CD QLED on a few tests, but overall, the QN90C looks a bit better, especially with HDR content. The QN90C has better tone mapping and tracks the PQ EOTF better, so HDR content looks better and is more accurate. The QN90C also uses a different panel type that natively has a wide viewing angle without neding additional filters, so there's no Ultra Wide Viewing Angle layer. It results in a slightly smaller viewing angle on the QN90C, but there's no distracting rainbow smearing from overhead lights.

Sony X95J
65" 75" 85"

The Samsung QN90A QLED is better than the Sony X95J, but if you really care about an accurate movie experience, some people might prefer the Sony. The Samsung has much better black uniformity and better contrast, but the Sony has a better local dimming feature, despite the Mini LED backlight on the Samsung. On the other hand, some people might prefer the Sony for watching HDR movies, as it tracks the EOTF more accurately, and many people prefer the processing on Sony TVs.

Samsung QN90B QLED
43" 50" 55" 65" 75" 85"

The Samsung QN90B QLED is very similar to its predecessor, the Samsung QN90A QLED. The QN90B has a wider viewing angle but worse black uniformity and more noticeable blooming in dark scenes. Small highlights in HDR content in dark scenes are significantly brighter on the QN90B, so they pop more.

Sony X95K
65" 75" 85"

The Samsung QN90A QLED and the Sony X95K are both high-end Mini LED TVs. Although they have many of the same features, the Samsung is a bit more polished overall with less blooming, higher peak brightness, and lower input lag for gaming. If you want a better all-around option, the Samsung TV is the better choice. However, the Sony TV supports Dolby Vision, so this is the better choice if you often stream content in Dolby Vision.

LG C1 OLED
48" 55" 65" 77" 83"

The LG C1 OLED and the Samsung QN90A QLED are both excellent TVs, but they use different panels. The LG is an OLED with a near-infinite contrast ratio, nearly instant response time, and wide viewing angles. The Samsung has a VA panel, so it still has an excellent contrast ratio, but its viewing angles are only decent. OLEDs don't get as bright as LED TVs, and the Samsung uses Mini LED backlighting, allowing it to get exceptionally bright and making it better suited to very bright rooms.

Sony X90K/X90CK
55" 65" 75" 85"

The Samsung QN90A QLED is better overall than the Sony X90K/X90CK. The Samsung delivers better picture quality than the Sony, with deeper blacks, less blooming, higher peak brightness, and a wider viewing angle. It also has FreeSync VRR support if you're a PC gamer. However, if you tend to watch Dolby Vision content from streaming services, the Sony TV supports it, which the Samsung doesn't.

Hisense U8/U8H
55" 65" 75"

The Hisense U8/U8H and the Samsung QN90A QLED offer very similar picture quality overall, but the Samsung has better processing and a wider viewing angle, so it's slightly better overall. The Hisense has better native contrast, and it has better accuracy in HDR, as most content is displayed at the brightness level the content creator intended. On the other hand, the Samsung TV has much better processing overall, so upscaled content looks a bit better, and there's less banding in areas of similar color. Thanks to its wide-angle filter, the Samsung is a much better choice for a wide seating arrangement, as the image remains consistent when viewed from the sides.

Samsung QN95B QLED
55" 65" 75" 85"

The Samsung QN90A QLED and the Samsung QN95B QLED deliver nearly identical performance; the biggest difference is their design. The QN95B's inputs are all housed in an external One Connect box instead of on the back of the TV. It helps deliver a cleaner setup, with a single cable going from the One Connect box to the TV, so it's easier to hide if you're going for a clean setup with no visible wires. The QN90A doesn't have this external input box, meaning your input cables have to be routed to the back of the TV instead.

Samsung QN85B QLED
55" 65" 75" 85"

The Samsung QN90A QLED is much better than the Samsung QN85B QLED for most users. The QN90A has a much better native contrast, so there's less blooming around bright objects in dark scenes, and it has much better reflection handling, so it's better suited for a bright room. On the other hand, whereas the QN90A only supports HDMI 2.1 bandwidth on one port, the QN85B supports HDMI 2.1 bandwidth on all four HDMI ports, so it's a bit more versatile, especially if you have multiple game consoles or a recent PC.

Sony A80J OLED
55" 65" 77"

The Samsung QN90A QLED and the Sony A80J OLED use different panel types, but both offer amazing performance. The Sony is an OLED with a near-infinite contrast ratio, while the Samsung has a VA panel, so its native contrast is more limited. The Samsung uses Mini LED backlighting, and its local dimming feature allows it to produce exceptionally deep blacks. You may, however, notice a bit of blooming, especially when viewing off-angle, whereas the Sony has no visible blooming. The biggest advantage the Samsung has over the Sony is that it gets exceptionally bright, so it's better for bright rooms and can bring out more highlights in HDR.

Hisense U8G
55" 65"

The Samsung QN90A QLED is a bit better than the Hisense U8G. The Samsung has better viewing angles, making it a better choice for a wide seating arrangement, and the local dimming feature is more effective at reducing black levels, improving contrast. The Samsung is also significantly brighter, but since the Hisense is also very bright, the difference is only noticeable with some content.

LG CX OLED
48" 55" 65" 77"

The LG GX OLED and the Samsung QN90A QLED are both excellent TVs, but they use different panel types. The LG uses an OLED panel that can turn individual pixels off, resulting in perfect black levels. It also has wider viewing angles and a near-instantaneous response time. However, the Samsung uses an LCD panel with Mini LED as backlighting, so it's much brighter, allowing it to make highlights pop in HDR. They both have a 120Hz panel with HDMI 2.1 support for gaming, but the Samsung has one HDMI 2.1 input, while the LG has four.

Samsung QN85A QLED
55" 65" 75" 85"

The Samsung QN90A QLED sits higher up in the lineup than the Samsung QN85A QLED, so it has better overall performance, but they use different panels. The QN90A uses a VA panel, providing a much higher contrast ratio to display deeper blacks. The QN90A also gets a bit brighter and has a slightly quicker response time, but neither should be too noticeable. On the other hand, the QN85A uses an ADS panel, so it has wider viewing angles, making it a better choice for wide seating arrangements.

LG C2 OLED
42" 48" 55" 65" 77" 83"

The LG C2 OLED and the Samsung QN90A QLED are impressive TVs, and the best depends on your viewing conditions. The LG is a better choice for a dim or dark room, as it has much better contrast and no blooming around bright objects in dark scenes. On the other hand, the Samsung TV is a better choice for a bright room, as it gets significantly brighter.

LG QNED90
65" 75" 86"

Although they use different panel technologies, each with strengths and weaknesses, the Samsung QN90A QLED is much better than the LG QNED90. The Samsung has much higher contrast, significantly better black uniformity, and a better local dimming feature, meaning that it looks better in a dark room. The Samsung also has higher peak brightness and much better reflection handling, so it's better in a bright room, too.

Samsung QN800A 8k QLED
65" 75" 85"

Despite having a lower resolution, the Samsung QN90A QLED is much better overall than the Samsung QN800A 8k QLED. The main difference is the improved dark room performance. The QN90A displays a wider color gamut, has a much better contrast ratio, and it has a far superior local dimming feature, as there's too much blooming around bright objects with the QN800A. The QN800A is an 8k TV, but since there isn't much 8k content available in 2021, it's worth getting the QN90A.

Samsung The Frame 2022 QLED
32" 43" 50" 55" 65" 75" 85"

The Samsung QN90A QLED and the Samsung The Frame 2022 QLED are different types of TVs from different lineups. The QN90A is the flagship QLED TV, and while they both use QLED technology, the QN90A uses Mini LED backlighting and has a local dimming feature to provide great black levels and make small highlights pop. The QN90A also gets much brighter in SDR, so it combats glare, but The Frame has a different screen finish with fewer mirror-like reflections. They both have the same gaming features, but the QN90A has four HDMI 2.1 inputs, while The Frame is limited to one.

Samsung Q90/Q90T QLED
55" 65" 75" 85"

The Samsung QN90A QLED is a slight improvement over its predecessor, the Samsung Q90/Q90T QLED, mainly because it uses Mini LED as its backlighting. This allows more control over its local dimming feature, causing deeper blacks and higher brightness. The QN90A also doesn't have issues with local dimming in 'Game' mode the way that the Q90T does. Overall, they're very similar TVs with many of the same features.

LG G2 OLED
55" 65" 77" 83" 97"

The LG G2 OLED is better than the Samsung QN90A QLED for most users. The LG has a near-infinite contrast ratio and perfect black uniformity, resulting in much better picture quality in a dark room, with no distracting blooming around bright objects. The Samsung gets significantly brighter, so it can better handle glare in a bright room, but it has worse picture quality and doesn't look as good as the LG in a dark room.

Samsung Q80/Q80T QLED
49" 50" 55" 65" 75" 85"

The Samsung QN90A QLED is better overall than the Samsung Q80/Q80T QLED. The QN90A uses Mini LED as its backlighting, so it gets significantly brighter and has improved local dimming, especially in 'Game Mode'. Other than that, each TV has the same inputs with HDMI 2.1 support. The QN90A is better for HDR content since it gets significantly brighter and has a slightly wider color gamut.

Samsung QN900A 8k QLED
65" 75" 85"

The Samsung QN90A QLED and the Samsung QN900A 8k QLED are high-end TVs in Samsung's Neo QLED series, which use Mini LED backlighting. While the QN900A is an 8k TV with a price tag to match, the 4k QN90A performs better overall. The QN90A has a higher native contrast ratio and a better local dimming feature. It also gets even brighter in both SDR and HDR.

LG QNED99 8k
65" 75" 86"

The Samsung QN90A QLED is much better overall than the LG QNED99 8k, but they're different types of TVs. The Samsung is a 4k TV with a VA panel that has a much better native contrast. Its Mini LED local dimming feature is also much better, providing a superior dark room viewing experience. The Samsung gets brighter, so it makes highlights pop more in HDR, and it supports VRR. However, the LG can display 8k content and it has an IPS-like panel with wider viewing angles.

LG NANO90 2021
55" 65" 75" 86"

The Samsung QN90A QLED is significantly better than the LG NANO90 2021. The Samsung is a high-end TV that uses Mini LED backlighting, so it gets extremely bright and delivers a more satisfying HDR experience than the LG. Even though the Samsung has a VA panel with a higher contrast ratio, it also has wider viewing angles than the LG, thanks to the 'Ultra Viewing Angle' technology. Also, the Samsung has a quicker response time, but they each have the same gaming features with HDMI 2.1 and VRR support. However, the LG is G-SYNC compatible, which the Samsung isn't.

Samsung Q80/Q80A QLED
55" 65" 75" 85"

The Samsung QN90A QLED is much better than the Samsung Q80/Q80A QLED. They use different panel types, so the VA panel on the QN90A has a higher contrast, and the Q80A has wider viewing angles thanks to its IPS panel, but the viewing angles are still decent on the QN90A. The QN90A uses Mini LED backlighting, providing a better local dimming feature and allowing it to get brighter, especially in HDR, so highlights pop more.

Hisense U9DG
75"

The Samsung QN90A QLED is better than the Hisense U9DG for most people. The Hisense has much better native contrast and a better local dimming feature, so it's a bit better for a completely dark room. On the other hand, the Samsung is significantly brighter, and it has better motion handling, with a significantly faster response time.

Sony X91J
85"

The Samsung QN90A QLED is better overall than the Sony X91J. While the Samsung is available in a range of sizes, from 43 to 85 inches, the Sony is only available in 85 inches. The Samsung uses Mini LED backlighting that allows it to get much brighter and have a better local dimming feature, so it's a better choice for watching HDR content. The Samsung is also a better choice for wide seating arrangements because it uses viewing angle technology to improve the viewing angles.

LG G1 OLED
55" 65" 77"

The LG G1 OLED is better than the Samsung QN90A QLED for most users. The LG has a near-infinite contrast ratio and perfect black uniformity, resulting in much better picture quality in a dark room, with no distracting blooming around bright objects. The Samsung gets significantly brighter, so it can better handle glare in a bright room, but it has worse picture quality and doesn't look as good as the LG in a dark room.

TCL 6 Series/R646 2021 QLED
55" 65" 75"

The Samsung QN90A QLED is better overall than the TCL 6 Series/R646 2021 QLED. They each have Mini LED backlighting, but the full-array local dimming feature on the Samsung has more dimming zones, so it produces deeper blacks in real content and has less blooming. It also has wider viewing angles thanks to Samsung's 'Ultra Viewing Angle' technology, but that means the TCL has a better native contrast ratio. The Samsung gets much brighter, especially in HDR, so it makes highlights pop more. TCL has one more HDMI 2.1 input compared to the Samsung, and even though it also has VRR support, its refresh rate range is more narrow than the one on the Samsung.

LG B1 OLED
55" 65" 77"

The LG B1 OLED and the Samsung QN90A QLED are both excellent TVs with different panel types. The LG has an OLED panel with perfect black levels, near-instantaneous response time, and wider viewing angles, and there's no blooming around bright objects. On the other hand, the Samsung has an LED panel that gets significantly brighter, making highlights in HDR pop more, and it doesn't risk permanent burn-in like OLEDs. 

LG A1 OLED
48" 55" 65" 77"

The Samsung QN90A QLED and the LG A1 OLED are very different TVs, as they use different panel technologies, each with their own strengths and weaknesses. The LG is a better choice for watching movies in a dark room, as it displays perfect blacks with no blooming, and has better uniformity. The Samsung is a better choice for gaming or for watching TV in a bright room, though, as it has a faster refresh rate, it supports advanced gaming features like HDMI 2.1 and variable refresh rate technology (VRR), and it's significantly brighter.

LG GX OLED
55" 65" 77"

The LG GX OLED and the Samsung QN90A QLED are both excellent TVs with different panel types. The LG's OLED panel provides an infinite contrast ratio, perfect black uniformity, and wide viewing angles. On the other hand, the Samsung's LED panel gets significantly brighter, which is great for watching HDR content, and it doesn't suffer from burn-in like the LG. In terms of gaming, they each have HDMI 2.1 support; the LG has four HDMI 2.1 inputs, while the Samsung just has one.

Sony A90J OLED
55" 65" 83"

The Sony A90J OLED and the Samsung QN90A QLED are both excellent all-around TVs, but they use different panel types. The Sony is an OLED, so it has perfect blacks and an infinite contrast ratio. The Samsung, on the other hand, is an LED TV, and its use of Mini LED backlighting allows it to get exceptionally bright. The Sony may be a better option if you prioritize movies and picture quality, but the Samsung is a better option for gaming since it has lower input lag.

LG NANO99 8k 2021
65" 75" 86"

The Samsung QN90A QLED is much better overall than the LG NANO99 8k 2021, but they have a few different features. The Samsung is a 4k TV with a VA panel and Mini LED backlighting that makes it get brighter, display deeper blacks, and have a better local dimming feature. The LG has a higher 8k resolution, and even though it has an IPS panel, its viewing angles aren't much better than those on the Samsung because of Samsung's 'Ultra Viewing Angle' technology. They each support HDMI 2.1 bandwidth and have 120Hz panels, but the Samsung has VRR support. The Samsung is also better for HDR because it displays a wider color gamut and has higher HDR peak brightness.

TCL 6 Series/R648 2021 8k QLED
65" 75"

The Samsung QN90A QLED is better overall than the TCL 6 Series/R648 2021 8k QLED. They both have Mini LED backlighting, and the Samsung gets much brighter, especially in HDR, and it has a better local dimming feature because there's less blooming. the Samsung has better viewing angles because of the 'Ultra Viewing Angle' technology, so it's a better choice for watching shows or sports in a wide seating area, and it has better reflection handling. The TCL is an 8k TV, so it supports higher-resolution signals than the Hisense, but the Hisense also displays native 4k content better because it doesn't have to upscale it.

Sony X950H
49" 55" 65" 75" 85"

The Samsung QN90A QLED is better overall than the Sony X950H, mainly because it has more gaming features. The Samsung has HDMI 2.1 support, allowing you to play 4k @ 120Hz games. It also has lower input lag and supports VRR to reduce screen tearing. In terms of picture quality, the Samsung uses Mini LED as its backlighting, so it gets much brighter and has a better local dimming feature in SDR, but the Sony's local dimming is better in HDR. Each TV has viewing angle technology to improve the viewing angles, but Samsung's is better, so it's a better choice for use in wide seating arrangements.

Vizio P Series Quantum X 2020
65" 75" 85"

The Samsung QN90A QLED is a bit better overall than the Vizio P Series Quantum X 2020. The Samsung gets a bit brighter, and it has wider viewing angles thanks to its 'Ultra Viewing Angle' technology. The Samsung also has better gaming performance because there aren't any bugs with its VRR, it supports the PS5 with 4k @ 120Hz games, and it has a quicker response time. However, the Vizio has a better contrast ratio because it doesn't have any viewing angle technology.

The Samsung QN90A's build quality is fantastic. Although the entire TV, except for the stand, is made of plastic, it feels very solid and well-put-together. The textured plastic feels premium. There aren't any obvious issues or loose parts, which is what you'd expect from a high-end model. It's a bit wobbly on the stand, but that's because the panel is so thin and easy to move, and it won't be an issue unless you regularly move your TV around.

The Samsung 55QN90A has remarkable HDR brightness. Small highlights stand out the way they are expected to, but in SDR, large areas are less bright due to the aggressive ABL. Surprisingly, real content gets even brighter than the test slides, so this TV delivers an impactful HDR experience. Real scenes are brighter than the Samsung QN90B QLED, but small highlights in dark scenes aren't as bright.

The EOTF follows the target PQ curve fairly well, but the overall image looks brighter than intended. It has a slow roll-off at its peak brightness, meaning you won't lose details in bright objects. If you still find the image too dim, then set Contrast Enhancer to 'High' and ST.2084 to its max. This results in a noticeably brighter image, as you can see in this EOTF, but it doesn't change the peak luminosity.

These results are from the 'Movie HDR' Picture Mode with Local Dimming on 'High', and Brightness and Contrast at their max, with all other image processing disabled.

The HDR brightness in Game Mode is incredible. It's only slightly more dim than outside of Game Mode, and it's still bright enough to make highlights stand out in HDR games. There's no frame dimming with small highlights either, but you have to update the TV to its latest firmware to be like that.

The EOTF follows the target better than outside of Game Mode, but some bright scenes are still over-brightened. You can make it brighter by using the same settings as outside of Game Mode.

These results are with Game Mode enabled, Local Dimming on 'High', Brightness and Contrast at their max, Color Tone set to 'Warm2', Sharpness at '0', and Color Gamut on 'Auto'. There's a new Game HDR setting, and it's meant to optimize the brightness according to the content. It resulted in a less bright image than originally tested, but feel free to enable it if you find it looks better with your game.

The Samsung QN90A has outstanding SDR brightness, and it gets much brighter than the Sony X95J. It easily gets bright enough to combat glare in well-lit rooms. However, the Automatic Brightness Limiter (ABL) causes large areas of bright colors, like in a hockey or basketball broadcast, to be more dim.

These results are from after calibration in the 'Movie' Picture Mode with Color Tone set to 'Warm2', Brightness to its max, and Local Dimming on 'High'.

If you want the brightest image possible and don't mind losing some image accuracy, set the Picture Mode to 'Dynamic' with Color Tone on 'Standard'. It reaches 1,511 cd/m² in the 10% window using these settings.

The Samsung QN90A has fantastic reflection handling. It handles external light sources well, but light scatters across the screen, creating a rainbow-like effect. It can be distracting during dim or dark scenes, as even indirect and dim light sources can cause this rainbow-like effect. However, it gets bright enough to fight glare with bright scenes, meaning they won't be as much of an issue.

The Samsung QN90A uses pulse width modulation (PWM) to dim its backlight. It flickers at such a high frequency that you won't notice it. However, the flicker frequency drops to 120Hz in the 'Dynamic', 'Natural', 'Standard', and 'Filmmaker' Picture Modes, or if you enable the Game Mode or Picture Clarity settings, but it flickers again at 960Hz with VRR enabled. This low flicker frequency can cause headaches if you're sensitive to flicker, and it also causes image duplications with 60Hz content.

Remote App Samsung SmartThings

Samsung released a redesigned remote for the QLED TVs in 2021, with a similar design to 2020's Samsung The Terrace. It still has the same quick-access buttons as the previous model but with brushed plastic at the bottom. The remote doesn't use disposable batteries anymore, and there's a solar panel on the back so you can charge it that way or with a USB-C cable. The voice control with Samsung's Bixby does most common demands, like opening apps, changing inputs, and changing settings, but it can't search for specific content in apps.

There are buttons underneath the Samsung branding in the center to change volume, channels, source, turn the TV On/Off, and you can also navigate the menu a bit.
