This TV was replaced by the Samsung QN90C/QN90CD QLED

The Samsung QN90B QLED is a premium 4k TV that replaces the Samsung QN90A QLED and is available in 43 to 85-inch sizes. This TV is part of Samsung's 2022 lineup, sitting between the Samsung QN85B QLED and the Samsung QN95B QLED. The QN95B is a similar TV with a One Connect box but a different processor. The QN90B features Samsung's Neo Quantum Processor 4k, and it uses Mini LED backlighting with over 900 dimming zones on larger sizes.

This TV comes with Samsung's proprietary Tizen OS smart interface, which offers a large selection of apps and games. The smart system has a few useful features, like the ability to control other smart devices and support for video calls with a compatible webcam. Besides that, it has gaming features you'd expect to find in a high-end TV, like variable refresh rate (VRR) support and HDMI 2.1 bandwidth, and the 43 and 50-inch sizes even have a 144Hz refresh rate.

Our Verdict

8.4 Mixed Usage

The Samsung QN90B is an impressive TV for most uses. It's great for watching TV shows or sports in a bright room thanks to its high peak brightness and superb reflection handling. It also upscales lower-resolution content well, which is important if your shows and sports aren't in 4k. It delivers an impactful HDR experience in a dark room thanks to its great contrast, impressive local dimming feature, and exceptional peak brightness in HDR, but it doesn't track the target PQ EOTF well. It also delivers an excellent gaming experience with low input lag, a fast pixel response time, and a slew of great gaming features. It's a fantastic choice for use as a PC monitor, as it supports most common resolutions, and chroma 4:4:4 is displayed properly, essential for clear text.

Pros
  • Bright enough to overcome glare in a bright room.
  • Image remains consistent at an angle.
  • Easy-to-use smart interface with a great selection of apps.
Cons
  • Some noticeable stutter in slow-panning shots.

Differences Between Sizes And Variants

We tested the 65-inch QN90B, and the results are also valid for the 55-inch (Samsung 55QN90B), 75-inch (Samsung 75QN90B), and 85-inch (Samsung 85QN90B). It's also available in 43-inch and 50-inch models, but they're a bit different as they support a higher refresh rate and have different screen coating; we tested the 43-inch model as a monitor. Note that with Samsung TVs, the six letters after the short model code (AAFXZA in this case) vary between specific retailers and regions and even between different retailers. The warehouse variant sold at Costco and other retailers is known as the Samsung QN90BD. There are no differences between the QN90BD and the QN90B, but the warehouse model comes with a five-year warranty.

Compared To Other TVs

The Samsung QN90B is an excellent TV overall, and it's one of the best 4k TVs with an LED backlight on the market. It's incredibly bright and versatile and fits well in almost any viewing environment. It also has an impressive selection of smart features and gaming features, so it's a great choice for pretty much anyone. While it's a fantastic high-end LED TV, it's still somewhat expensive, so if you're on a tighter budget and don't need the best performance, a mid-range TV like the Hisense U8/U8H is still a great alternative.

For more options, check out our recommendations for the best TVs, the best QLED TVs, and the best 4k gaming TVs.

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

The Samsung QN90C/QN90CD QLED is the replacement model for the Samsung QN90B QLED, and they each have their strengths and weaknesses. The QN90C has better tone mapping and tracks the PQ EOTF better, so HDR content looks much better, despite the QN90B's better measurements on some aspects of picture quality. The QN90C also uses a different panel type that natively has a wider viewing angle without needing 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.

Samsung QN90A QLED
43" 50" 55" 65" 75" 85" 98"

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.

Samsung QN85C/QN85CD QLED
55" 65" 75" 85"

The Samsung QN90B QLED is better than the Samsung QN85C QLED. The QN90B gets much brighter than the QN85C, but in practice, this isn't always noticeable as most content just isn't mastered to take advantage of such high brightness levels. The QN85C is the more accurate TV of the two; it respects the content creator's intent well. However, the QN90B is the more colorful TV, with a wider color gamut and better color volume, and it has much better reflection handling, although it does have some rainbow smearing.

Samsung QN95B QLED
55" 65" 75" 85"

The Samsung QN90B QLED and the Samsung QN95B QLED deliver nearly identical performance; the biggest difference between them 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 overall, 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 QN90B doesn't have this external input box, so your input cables have to be routed to the back of the TV instead.

TCL QM8/QM850G QLED
65" 75" 85" 98"

The TCL QM8/QM850G QLED and the Samsung QN90B QLED are similar TVs, although the TCL is slightly better than the Samsung regarding contrast and brightness, making it the punchier TV overall. The Samsung does, however, have a much better viewing angle and better sharpness processing when upscaling low-resolution content, so it's the better TV to watch sports or TV shows with friends. It's also less buggy than the TCL, which is full of strange quirks.

Samsung QN85B QLED
55" 65" 75" 85"

The Samsung QN90B QLED is much better than the Samsung QN85B QLED. The QN90B has much better contrast, with deeper blacks and better uniformity in dark scenes. The QN90B also has much better reflection handling, so it's a better choice for a bright room, and it gets significantly brighter during most scenes in HDR.

Sony X95K
65" 75" 85"

The Samsung QN90B QLED and the Sony X95K are both Mini LED TVs, but the Samsung is just a bit better overall. The Samsung is better to use in dark rooms as it has less blooming around bright objects, and even in bright rooms, it gets brighter. If you're a gamer, it's better to go for the Samsung as it has lower input lag and supports FreeSync, which the Sony doesn't.

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

The LG C2 OLED is better overall than the Samsung QN90B QLED, but choosing one over the other also 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.

Samsung S95B OLED
55" 65"

The Samsung S95B OLED is a better TV than the Samsung QN90B QLED. The main strength of the S95B is that it uses a QD-OLED panel to display perfect blacks and much brighter and more vivid colors than the QN90B, which makes the S95B the better choice for watching content in dark rooms. On the other hand, the QN90B is better if you need something for a really bright room, as it gets much brighter.

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

The Samsung QN90B QLED is better overall than the Sony X90K/X90CK. The Samsung gets brighter and has a better local dimming feature, so it displays deeper blacks with real content, meaning it's a better choice for well-lit and dark rooms. If you're also a gamer, the Samsung TV has a few more features like FreeSync VRR support. Lastly, the Samsung is better to use in a wide seating area because it has a wider viewing angle that makes the image remain consistent from the sides.

Hisense U8/U8H
55" 65" 75"

The Hisense U8/U8H and the Samsung QN90B QLED deliver very similar picture quality overall, but the Samsung is a bit better overall. The Hisense has better native contrast, and it displays content closer to what 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 Q90/Q90T QLED
55" 65" 75" 85"

The Samsung QN90B QLED is a bit better than the Samsung Q90/Q90T QLED. The newer QN90B is a lot brighter, and it has better contrast with local dimming. The QN90B is also better for gaming, as all four of its HDMI ports support HDMI 2.1 bandwidth, meaning you can take full advantage of multiple consoles.

Sony X90J
50" 55" 65" 75"

The Samsung QN90B QLED is much better than the Sony X90J. The Samsung has much better reflection handling, and it's significantly brighter in SDR, meaning it can handle more glare in a brighter room. The Samsung also has better contrast with local dimming and much higher brightness in HDR, so bright highlights stand out better. Finally, the Samsung has a better viewing angle, so it's a better choice for a wide seating arrangement.

Sony X95J
65" 75" 85"

The Samsung QN90B QLED is better than the Sony X95J for most users. The Samsung has better contrast and a wider viewing angle, and it's significantly brighter, so small highlights stand out much better in dark scenes. On the other hand, the Sony TV has better processing, with better gradient handling and better tone mapping, so it's a slightly better choice for cinephiles. The Sony also has a slightly better local dimming feature, especially in 'Game' Mode.

Sony A95K OLED
55" 65"

The Sony A95K delivers a much better dark room viewing experience than the Samsung QN90B QLED. The Sony’s near-infinite contrast ratio delivers incredibly deep, uniform blacks and lets bright highlights stand out with no blooming. The A95K also delivers a more varied HDR experience because it can display a wider range of colors. On the other hand, the QN90B gets significantly brighter, so it's a better choice for a bright room with lots of natural light.

The Samsung QN90B has a modern, sleek design, with incredibly thin bezels and a slim stand. The heavy central stand looks great and takes up very little space, but it doesn't prevent all wobble.

Stand

The center-mounted stand is quite heavy but small, so it doesn't take up a lot of space on your table. Due to the relatively small size of the stand, the TV tends to wobble easily.

Footprint of the stand on the 65-inch model: 13.3" x 11.2". The stand lifts the TV about 2.5 inches above the table, so some thinner soundbars fit in front of it without blocking the screen.

Design
Back
Wall Mount VESA 400x300

The back of the TV is mainly plastic, with fine horizontal etched lines that give off a brushed aluminum look. There are tracks along the back and the stand (see here), which help with cable management, but you won't be able to use those if you wall-mount the TV. Unlike the Samsung QN95B QLED, which uses an external input box known as the One Connect box, the inputs are in the back of the TV. This means they're difficult to access if you wall-mount the TV with a fixed bracket.

Build Quality

The build quality is fantastic. The base is metal and quite solid, and the materials used feel premium. The back panel is mainly plastic and flexes easily, but this isn't unusual and doesn't cause any issues. The stand is extremely heavy, but due to its small size, it doesn't support the TV very well, so the screen wobbles easily.

The Samsung QN90B has an excellent contrast ratio. With Local Dimming on 'High,' it displays deep and inky blacks next to bright highlights in dark rooms. You can only disable Local Dimming in PC mode through the service menu, which we did for this test, but considering it has a low contrast ratio without local dimming, there isn't a reason for you to do this. Check out the newer Samsung QN90D/QN90DD QLED if you want a similar TV with better contrast.

The transition between dimming zones is decent, but it isn't as good as you'd expect from a high-end TV. The local dimming algorithm can't keep up well with fast-moving objects transitioning between dimming zones. While this isn't noticeable with most content, it can get distracting with fast-moving objects on dark backgrounds, as the leading edge is darker and the trailing edge has a bit of a halo effect.

Contrast And Dark Details In Game Mode

Unfortunately, like most Samsung TVs, the local dimming feature in Game Mode seems to be spreading highlights out over a greater number of zones, so there's a bit more noticeable blooming compared to outside of Game Mode. The processing is also slightly slower, so zone transitions are more noticeable. However, it's mainly due to the increased blooming.

The Samsung QN90B is exceptionally bright in HDR. Small specular highlights are incredibly bright, so fine details stand out in any scene. Large, bright scenes are significantly dimmer because of the somewhat aggressive Automatic Brightness Limiter (ABL), but they're still bright enough for a good HDR experience. The display's brightness doesn't fade the longer highlights stay on the screen, which is great. These results are from after calibrating the HDR white point with the following settings:

  • Picture Mode: Movie
  • Brightness: Max
  • Contrast: Max
  • Local Dimming: High
  • Color Tone: Warm2

The 'Dynamic' Picture Mode is even brighter, reaching a peak brightness of 3,126 cd/m² with a 10% window, but it can't maintain those brightness levels, and the brightness decreases after a few seconds.

The HDR brightness in Game Mode is fantastic. While it doesn't get as bright as outside of it, it's still bright enough to make highlights pop in HDR for a satisfying HDR experience. These results are from after calibrating the HDR white point with these settings:

  • Picture Mode: Game
  • Brightness: Max
  • Contrast: Max
  • Local Dimming: High
  • Color Tone: Warm2
  • HDR10+ Gaming: Basic
  • Color Space: Auto

Unfortunately, the Samsung QN90B QLED doesn't track the PQ EOTF properly, and most scenes appear significantly brighter than the content creator intended. There's also a very sharp cutoff at the TV's peak brightness, which causes bright white highlights to clip, so fine details are lost. It also behaves differently with different content, as content mastered at 4,000 cd/m² starts to roll off at lower peak brightness, and the TV's tone mapping kicks in earlier than with 1,000 and 600 cd/m² content.

There's some concern that some Samsung TVs detect when they're being calibrated or tested for a review and adjust the output to be more accurate. We measured the PQ EOTF with different window sizes and found that although it tracks the PQ EOTF accurately with more standard window sizes, it doesn't track accurately with real content.

PQ EOTF charts with different window sizes:

The EOTF performs similarly in Game Mode, but it gets even brighter than the target EOTF. You can try enabling Game HDR to get better PQ EOTF tracking, but it's still too bright.

This TV has fantastic peak brightness in SDR. It's bright enough to overcome glare in any room, even if you have a lot of windows or lights. Like in HDR, large, bright areas are dimmer due to its ABL, which means that some content, like sports, is dimmer, but it's still incredibly bright.

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

This TV has an excellent color gamut. It has fantastic coverage of the DCI-P3 color space used by most current HDR content, so images look vivid and lifelike. It has decent coverage of the wider Rec. 2020 color space, and the tone mapping is good, ensuring fine details are preserved and easy to see in areas of vibrant, saturated color.

The Samsung QN90B has good accuracy before calibration. Colors have excellent accuracy overall, but some colors are still off. The color temperature is on the warm side, but it isn't bad enough to be noticeable. The white balance is okay, but brighter shades of gray are off. Gamma is close to the 2.2 target for a moderately lit room, but bright scenes are a bit too bright.

The Samsung QN90B has decent gray uniformity overall. There are a few patchy spots near the center, which is a bit distracting when watching sports. The sides of the screen are also a bit darker than the center, but this isn't very noticeable with normal content. Gray uniformity in near-black scenes is much better, with no noticeable issues.

This TV has amazing black uniformity with Local Dimming on 'High'. It displays deep blacks, but there's still some blooming around bright objects on dark backgrounds. Although you can only disable Local Dimming through the service menu, we still did so for testing, and black uniformity is worse with it off as blacks look blue and there's clouding throughout.

The Samsung QN90B has a good viewing angle. It's great if you have a wide seating arrangement or like to move around with the TV on, as the image remains consistent at an angle. The 43-inch and 50-inch models lack Samsung's Ultra Viewing Angle Layer, so they have a worse viewing angle. You can see the viewing angle of the 43-inch model here.

The Samsung QN90B Neo QLED TV has superb reflection handling. The glossy coating significantly reduces the intensity of direct reflections, so glare isn't as distracting. Sadly, like other TVs with the Ultra Viewing Angle layer, there's a rainbow-like effect that scatters across the screen, but the 43 and 50-inch models don't have this layer and don't have this rainbow-like issue, as you can see here. The replacement model in Samsung's 2023 lineup, the Samsung QN90C/QN90CD QLED, doesn't have the same rainbow smearing on it.

The Samsung QN90B has an excellent pixel response time. Most transitions are extremely quick, resulting in a short blur trail behind fast-moving objects. There's still some noticeable persistence blur, and there's overshoot in some dark transitions. This causes some inverse ghosting, but it isn't very noticeable.

PWM Dimming Frequency

This TV uses pulse width modulation (PWM) to dim its backlight, and the flicker frequency varies between picture modes and with certain settings. In 'Movie' mode, with the backlight set between '46' and the max of '50', the backlight flickers at 120Hz. However, it increases to 960Hz with a backlight setting below '46'. 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. This low flicker frequency can cause headaches if you're sensitive to flicker, and it also causes image duplications with 60Hz content.

The Samsung QN90B Neo QLED has an optional backlight strobing feature, commonly known as BFI. This feature reduces persistence blur caused by the TV's fast response time. It works at both 60Hz and 120Hz, but the timing is a bit off, causing a duplicated image.

This TV has a feature to increase the frame rate of low-frame-rate content up to 120Hz. It's okay overall on this TV, but it looks best in slow-paced scenes. In busy scenes with a lot of action, it doesn't look very good, and there are a lot of artifacts. Unlike some TVs, which stop interpolating when they can't keep up, this one keeps going, so there are more and more artifacts in busy scenes. Even the smaller sizes, like the 43-inch QN90B, support motion interpolation with 30 fps and 60 fps content and perform like the larger sizes.

Due to this TV's quick pixel response time, low frame rate content, like movies, appears to stutter. It's mainly noticeable in slow panning shots. If this bothers you, the optional motion interpolation or backlight strobing features can help, but those features create other issues, so there's no perfect solution.

The Samsung QN90B has very low input lag in Game Mode. This results in a very responsive gaming experience, ensuring your actions align with what you see on screen. If you're a fan of motion interpolation, Samsung's Game Motion Plus feature allows you to interpolate low frame rate games, improving motion clarity without adding much input lag. With the setting at its max, there's higher input lag than with it disabled, but it's still good for casual gamers.

This TV has a decent frequency response. The low-frequency extension, or LFE, is high, so it can't produce much thump or rumble, but this is normal for TVs. The frequency response above the LFE is well-balanced at moderate listening levels. However, there's a noticeable dip in the treble range at max volume, making dialogue harder to understand. It has an optional room correction feature, which was enabled for these measurements.

There are four quick-access buttons for the most popular streaming services; unfortunately, there's no way to remap these to your favorites. You can recharge the remote via a solar panel on the back or with a USB-C cable (sold separately).

The Samsung QN90B is compatible with multiple voice assistants, including Bixby, Google Assistant, and Alexa, but you have to use the remote as it doesn't have a hands-free mode. Voice controls work well and allow you to launch apps, change inputs, or adjust certain settings.
