The Samsung Q90T is an excellent 4k QLED TV. It's feature-rich, and it delivers stunning picture quality in nearly every type of content. Its simple and elegant design should fit easily into any room, and it performs well in both dark or bright environments. Motion handling is superb thanks to its incredibly fast response time and Black Frame Insertion feature, and gamers should be pleased with its exceptionally low input lag and FreeSync support. HDR content is delivered with vibrant colors and bright highlights, as it has an impressive color gamut and high peak brightness. Its Tizen OS interface is easy to navigate, and there are tons of apps available. There are some minor uniformity issues that may disappoint sports fans, but as a whole, it's a TV that should satisfy most people.

Differences Between Sizes And Variants

We tested the 55" (QN55Q90T) variant, and for the most part, we expect our review to be valid for the 65" (QN65Q90T), the 75" (QN75Q90T), and the 85" variant (QN85Q90T). There's a Q95T model that's only available in Europe. It has mostly the same features, except that it has the One Connect Box that was featured on the Samsung Q90/Q90R QLED.

If someone comes across a different type of panel or if their Samsung Q90T doesn't correspond to our review, let us know and we will update the review.

Compared To Other TVs

Comparison picture

Top left: LG CX (CX OLED). Bottom left: Sony X950G (XBR55X950G). Middle: Samsung Q90T (QN55Q90T). Top right: Samsung Q90R (QN55Q90R). Bottom right: Vizio P Series Quantum X 2019 (PX65-G1).

The Samsung Q90T is an excellent TV suitable for every type of content. Compared to 2019's Samsung Q90/Q90R QLED, it performs almost identically, but it loses some features like the One Connect Box, and it no longer supports Samsung's no-gap wall mount. However, it's one of the best LED TVs on the market in 2020, and most people should be happy with it. For other options, check out our recommendations for the best TVs, the best 4k HDR TVs, and the best 4k gaming TVs.

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

The Samsung Q90/Q90T QLED and the Samsung Q80/Q80T QLED are very much alike, as they offer identical features. The biggest difference is in terms of performance, where the Q90T performs slightly better than the Q80T. The Q90T has a higher contrast ratio and peak brightness, and it has much better gradient performance, resulting in less banding. However, the Q80T has better color accuracy and black uniformity, although these could be due to panel variance.

LG CX OLED
48" 55" 65" 77"

The LG CX OLED is a better TV for most uses than the Samsung Q90T QLED, though the Q90Tstill performs excellent overall. The LG has perfect blacks thanks to its OLED panel and has excellent viewing angles and better motion handling. It also has much better gray uniformity and has a wider color gamut with more accurate colors out-of-the-box. On the other hand, the Samsung can get quite a bit brighter and has lower input lag. The Samsung also doesn't run the risk of permanent image retention or burn-in, like the OLED panel on the LG does. This likely won't be an issue for most OLED owners who watch normal, varied content, but can be a concern if you watch a ton of static images.

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

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.

Samsung Q80/Q80R QLED
55" 65" 75" 82"

The Samsung Q90T QLED and the Samsung Q80/Q80R QLED are nearly identical in terms of feature set and overall performance, as the Q90T is a replacement of the Q80R. Other than the added eARC support, the Q90T has a higher HDR peak brightness and a significantly faster response time, resulting in less motion blur. Input lag is also lower on the Q90T, but the Q80R has better black uniformity and out-of-the-box color accuracy.

Samsung QN90B QLED
43" 50" 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 X900H
55" 65" 75" 85"

The Samsung Q90/Q90T QLED and the Sony X900H are two great TVs, although the Samsung is better for most uses. The Samsung gets much brighter, especially in HDR, and combined with its better local dimming feature, it offers a superior HDR viewing experience. It also has wider viewing angles thanks to Samsung's 'Ultra Viewing Angle', but that also means the Sony has a better native contrast ratio.

Samsung QN85A QLED
55" 65" 75" 85"

The Samsung Q90/Q90T QLED is better than the Samsung QN85A QLED. The Q90T looks better in a dark room thanks to its much higher native contrast and better local dimming system. The Q90T also has better black uniformity, with less blooming around bright objects and less clouding in dark scenes.

Samsung Q90/Q90R QLED
65" 75" 82"

The Samsung Q90T QLED and the Samsung Q90/Q90R QLED have similar performance overall. The Q90T is the Q90R's replacement in name only, as it doesn't have the One Connect Box and its feature set is closer to the Q80R. The Q90T has better viewing angles due to the new implementation of the 'Ultra Viewing Angle' layer, and it has a lower input lag. The Q90T gains eARC support, but its black uniformity is noticeably worse compared to the Q90R.

Sony X95J
65" 75" 85"

The Samsung Q90/Q90T QLED is better than the Sony X95J. The Samsung has better contrast, better reflection handling, and better viewing angles. The Samsung is better for gaming as it has lower input lag for a more responsive feel. The Sony has a better local dimming feature, and many people prefer Sony's picture processing system.

Samsung Q800T 8k QLED
65" 75" 82"

The Samsung Q90T QLED is better than the Samsung Q800T 8k QLED. The Q90T is a 4k TV that has a better contrast ratio, slightly better uniformity, much better reflection handling, better out-of-the-box color accuracy, and a quicker response time. Both TVs have one HDMI 2.1 input, so they're both future-proof, but the Q800T can display 8k content.

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

The Samsung Q90/Q90T QLED is significantly better overall than the Samsung Q80/Q80A QLED. The Q90T has a much higher contrast ratio and delivers better HDR performance because it has a better local dimming feature and gets brighter in HDR to make highlights pop. They each have many of the same gaming features and performance, but the Q90T is G-SYNC compatible, which the Q80A isn't.

Sony X90J
50" 55" 65" 75"

For the most part, the Samsung Q90/Q90T QLED is better than the Sony X90J. The Samsung has a lower native contrast ratio due to its 'Ultra Viewing Angle' layer, but its local dimming improves the contrast significantly. It also gets a lot brighter in both SDR and HDR, reaching well above 1000 cd/m² for a much better HDR experience. The Samsung has a wider color gamut, lower input lag, and supports FreeSync VRR. Also, it can display a 1440p @ 120Hz signal on the Xbox Series X, which the Sony can't.

Samsung Q70/Q70T QLED
55" 65" 75" 82" 85"

The Samsung Q90/Q90T QLED is higher in the Samsung lineup than the Samsung Q70/Q70T QLED, so it has much better performance. The Q90T has a local dimming feature, which the Q70T doesn't, allowing it to display deeper blacks. The Q90T gets brighter and has wider viewing angles thanks to Samsung's 'Ultra Viewing Angle' layer as well. In terms of gaming, they each have a 120Hz panel and VRR support, but the Q90T has a much quicker response time.

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

The Samsung Q90/Q90T QLED and the LG C1 OLED are excellent TVs, but they use different panel types. The LG has an OLED panel with a near-infinite contrast because it can turn off individual pixels, and there's no blooming around bright objects. It also has wider viewing angles and a quicker response time than the Samsung. On the other side, the Samsung gets much brighter because it has an LED panel, making it a better choice for well-lit rooms. Also, LED TVs appear to be immune to burn-in, unlike OLEDs.

LG C9 OLED
55" 65" 77"

Overall, the LG C9 OLED is better than the Samsung Q90T QLED. Due to OLED's emissive technology, the LG can produce perfect blacks. The LG also has better uniformity, faster response time, and it supports NVIDIA's G-SYNC to reduce screen tearing when gaming. However, the Samsung can get much brighter, it has lower input lag, and there's no risk of permanent burn-in.

Samsung QN900A 8k QLED
65" 75" 85"

The Samsung Q90/Q90T QLED and the Samsung QN900A 8k QLED are great TVs with similar features. While the Q90T can't display 8k like the QN900A, there still isn't enough 8k content to make it worth the upgrade. The Q90T has a better contrast ratio and better local dimming, so it can deliver deeper blacks. The QN900A does offer a bit more gaming features, though, with more ports that support HDMI 2.1 bandwidth.

Samsung QN800A 8k QLED
65" 75" 85"

The Samsung Q90/Q90T QLED is better overall than the Samsung QN800A 8k QLED. The main difference between the two is that the Q90T has a much better native contrast ratio and full-array local dimming feature, so it displays deeper blacks. The QN800A uses Mini LED backlighting, but there's too much blooming. The Q90T also has a quicker response time for smoother motion. The QN800A supports 8k signals, which the Q90T doesn't, but there's not much native 8k content available in 2021 anyways.

Sony A8H OLED
55" 65"

The Sony A8H OLED is a bit better than the Samsung Q90/Q90T QLED. Since the Sony is an OLED, it has an infinite contrast ratio that the Samsung just can't match. Screen uniformity is much better on the Sony, and so are the viewing angles. Also, the Sony has a much faster response time. However, the Samsung gets brighter, it has a significantly lower input lag, and it supports variable refresh rate to reduce screen tearing when gaming.

Samsung Q900TS 8k QLED
65" 75" 85"

The Samsung Q900TS 8k QLED and the Samsung Q90/Q90T QLED are both high-end QLED TVs with a lot of great features and performance in the same ballpark. That said, the Q90T offers better value for the price. It has a higher native contrast ratio and much better viewing angles than the Q900TS. While both have fast response times and FreeSync VRR support, the Q90T is also compatible with G-SYNC. The biggest difference is that the Q90T is a 4k TV and the Q900TS is 8k, but since there's still very little 8k content, the value of 8k at this point is questionable.

Samsung The Terrace
55" 65" 75"

The Samsung Q90T QLED and the Samsung The Terrace score similarly overall, but they each have their pros and cons. The Q90T has much wider viewing angles, its local dimming performs better, and it has variable refresh rate support. The Terrace is an outdoor TV that can get significantly brighter in SDR and HDR, and it has a higher native contrast ratio since it doesn't have Samsung's 'Ultra Viewing Angle' layer.

LG GX OLED
55" 65" 77"

The Samsung Q90/Q90T QLED and the LG GX OLED are both excellent premium TVs with different panel types. The LG uses an OLED panel that has an infinite contrast ratio, resulting in perfect blacks. It also has wider viewing angles than the Samsung and the response time is much quicker, resulting in smooth motion. On the other hand, the Samsung is a better choice for use in well-lit rooms or HDR content because it gets much brighter in both SDR and HDR. Also, the Samsung doesn't have the risk of permanent burn-in like the LG.

Hisense U8G
55" 65"

The Samsung Q90/Q90T QLED is slightly better than the Hisense U8G for most uses. The Hisense has higher native contrast, but the local dimming feature on the Samsung is more effective at boosting contrast. The Samsung is a lot brighter in HDR, and it has better viewing angles.

Sony A8G OLED
55" 65"

Overall, the Samsung Q90T QLED performs about the same as the Sony A8G OLED. That said, these two TVs are wildly different, as the Sony is an OLED that can produce perfect blacks, while the Samsung is an LED TV that uses backlighting, causing blacks to appear a bit grayish in some scenes. The Samsung can get brighter to deliver a better HDR experience, and it has low input lag as well as FreeSync support. On the other hand, the Sony has much wider viewing angles, and its black and gray uniformity are significantly better.

The Samsung Q90T has an exceptional design. It's clean, modern, and simple. The bezels are thin on all sides, and the stand is center-mounted, similar to the Samsung Q90/Q90R QLED. The biggest change is the loss of the One Connect Box, as this TV is more of a replacement for the Samsung Q80/Q80R QLED. There's a Q95T model that still has the One Connect Box, but it seems to be available only in Europe at this time.

If you're in North America and you want a TV that has the One Connect Box and supports the no-gap wall-mount, check out the Samsung The Frame 2020.

Wall Mount VESA 200x200

The back of the TV is plastic, and it has a fine texture etched into it horizontally, giving it a brushed look. The inputs are side-facing, making it easy to access when wall-mounted, and some grooves guide all the cables towards the stand, where there are also grooves that serve as cable management.

Build Quality

The build quality is outstanding. The TV feels very well-built, and although there's a bit of wobble, it's mainly due to the stand being center-mounted. It's not as good as the Samsung Q90/Q90R QLED, as the right side of the back panel has some flex, and the plastic used for cable management feels cheap.

The Samsung Q90T has an excellent SDR peak brightness. It's good enough to overcome glare even in very bright rooms; however, brightness varies quite a bit when displaying different content, with the 100% window being the dimmest. If you want a TV that gets brighter for outdoor use, check out the Samsung The Terrace.

We measured the SDR peak brightness after calibration in the 'Movie' Picture Mode, with Backlight set to maximum, Color Temperature set to 'Warm 2', and Local Dimming set to 'High.'

If you don't mind losing a bit of image accuracy, you can get a brighter image by setting the Picture Mode to 'Dynamic' and Local Dimming to 'High'. These settings allow us to reach 1652 cd/m² in the 10% window.

Update 07/16/2021: We've added two new videos demonstrating the local dimming feature with real content.

The Samsung Q90T has a great local dimming feature. Samsung's new algorithm seems to activate the backlight in more zones around bright objects. This makes blooming less intense but has the side effect of making a larger section of the screen look a bit grayish. There's still blooming in some content, and highlights can appear dimmer; however, it's difficult to tell whether it's due to the implementation of the local dimming or the mastering of the content itself. Subtitles are handled well, as they're not as blinding in dark scenes and cause less blooming when compared to the Samsung Q90/Q90R QLED.

Update 07/16/2021: We retested the local dimming feature in Game Mode with the latest firmware. Local dimming performs better than it did before in Game Mode, with improved zone transitions and better subtitle handling. It doesn't raise the black level as much as before, but it's still a bit worse than out of Game Mode.

Update 09/17/2021: Multiple owners have reported a decrease in peak brightness and a strange local dimming bug since the firmware v1506 was released. We tested it on our unit with v2016, but there's no issue with our unit. Our unit has been modified a bit in the service menu, but we don't expect those changes to impact this issue.

Update 07/16/2021: We retested the peak brightness in HDR with the latest firmware and found that it's increased a bit across the board. Small highlights increased the most, with an ~100 cd/m² increase.

This TV has outstanding HDR peak brightness. The Samsung Q90T can get very bright, enough to deliver a fantastic HDR experience. However, just like in SDR, the brightness varies depending on the scene and gets dimmer as larger areas of the screen is lit.

We measured the HDR peak brightness before calibration in the 'Movie HDR' Picture Mode, with Local Dimming set to 'High', Contrast Enhancer disabled, and Brightness and Contrast set to max.

If you want a brighter image in HDR and don't mind losing image accuracy, set the Picture Mode to 'Dynamic HDR' and Local Dimming to 'High'. These settings allow us to reach 2173 cd/m² in the 10% window.

Update 07/16/2021: We retested the peak brightness in HDR in Game Mode with the latest firmware and found that the peak brightness behavior has changed significantly. Small highlights are significantly dimmer than before, as the local dimming feature seems to be dimming them unnecessarily. Larger window sizes are significantly brighter than before, though, with the 10% and 25% windows increasing by about 400 cd/m².

Gray uniformity is decent, but this can vary between individual units. The edges of the screen appear darker, and there's some dirty screen effect throughout the screen, which can be distracting when watching sports or large areas of uniform color. However, uniformity is much better in dark scenes.

For a VA panel, the Samsung Q90T's viewing angles are decent, suitable for a moderately large room. It has Samsung's 'Ultra Viewing Angle' layer, which greatly improves viewing angles at the expense of a lower contrast ratio.

Two separate runs were performed to take our measurements. The first run was done with local dimming disabled to measure gamma, black level, and lightness. The second was with local dimming set to 'Low', allowing us to measure color.

The TV's local dimming can't be disabled through the normal settings menu. To turn it off, you must first disable PC Mode Dimming within the TV's service menu, and then activate PC Mode.

Out of the box, the Samsung Q90T has decent color accuracy. Most colors are fairly accurate, but white balance is quite off, and the preset 'Warm 2' Color Temperature is much warmer than our target of 6500K, giving the image a reddish tint. Gamma doesn't follow the target all that well, with most scenes appearing darker than they should. Note that color accuracy can vary between individual units. The replacement of this TV, the Samsung QN90A QLED, has much better out-of-the-box color accuracy.

Update 09/29/2020: We've changed the status of the Auto-Calibration function from 'Untested' to 'Undetermined', as the Samsung Q90T still isn't listed as being compatible with CalMAN.

After calibration, color accuracy is exceptional. The remaining inaccuracies shouldn't be noticeable to the naked eye, and the color temperature is close to our 6500K target, although still a bit on the warm side. Gamma follows the target well, but bright scenes look slightly darker than they should.

The pixels are a little blurry due to the TV's 'Ultra Viewing Angle' filter. It's a different implementation of the technology than what we had observed on the Samsung Q90/Q90R QLED, allowing us to see the pixels much more clearly. You can also see the wide viewing angle filter in this photo.

The Samsung Q90T uses a BGR sub-pixel structure. It doesn't affect picture quality, but it can affect text clarity when using the TV as a PC monitor. You can read more about it here.

Great HDR color gamut. Coverage of the commonly-used DCI P3 is excellent, and coverage of the wider Rec. 2020 is decent. In 'Movie' mode, the EOTF is a bit brighter than the input stimulus until the roll-off.

In 'Game' mode, there's a Black Equalizer feature that is set to '2' by default, causing the EOTF to be less accurate. With it set to '0', the 'Game' mode EOTF is much closer to the target, resulting in this EOTF.

If you find HDR content too dim, you can make it brighter by setting Contrast Enhancer to 'High' and set ST.2084 to maximum. These settings result in a much brighter image, as you can see in this EOTF.

The Samsung Q90T can interpolate lower frame rate content up to 120Hz, commonly known as the 'Soap Opera Effect'. Generally speaking, this feature does a fairly good job and the picture looks good. We did notice some artifacts when interpolating 60fps content up to 120fps; however, it seems to be an issue that only happens with our test pattern and is unlikely to be noticeable in real content.

To use motion interpolation, set Picture Clarity to 'Custom', and adjust the Judder Reduction slider to '10' for 30fps content, or adjust the Blur Reduction to '10' for 60fps content.

If you want to use motion interpolation when gaming, it's essentially the same steps, but within the Game Motion Plus settings menu. Start by enabling Game Motion Plus, then set the Judder Reduction slider to '10' for games that run at 30fps natively, or set the Blur Reduction slider to '10' for games that normally run at 60fps.

Update 11/17/2020: We've retested the TV with an HDMI 2.1 source and the latest firmware (version 1402). HDMI 2.1 is only supported on the HDMI 4 port. It can display 4k @ 120Hz with VRR enabled, and it also works with NVIDIA's G-SYNC.

Update 08/19/2020: We changed HDMI Forum VRR to 'Unknown' because we currently don't have an accurate way to test for HDMI Forum VRR compatibility. Once we do, we'll test for it and update the review.

The Samsung Q90T supports FreeSync to reduce screen tearing when gaming. Like other 2020 Samsung TVs that support VRR, there's no setting for it. It now turns on automatically when a game is launched from a device that has VRR enabled. Sadly, it doesn't support G-SYNC.

Update 11/17/2020: We've retested the TV with an NVIDIA RTX 3080 graphics card and the latest firmware (version 1402). We've added the input lag for 4k @ 120Hz and updated the results for the other resolutions.

Update 09/18/2020: We updated the firmware of the TV to 1301 and remeasured input lag outside of Game mode. The measurements were roughly the same as before the firmware update and within manufacturing tolerances. We got 72.7ms at 4k and 90.1ms at 1080p.

The input lag on the Samsung Q90T is outstanding. It's slightly higher when playing games at 4k with VRR, but it shouldn't be noticeable for most people. To get low latency, you must be in 'Game' mode. For PC use, 'Game' must be used with 'PC' mode to get the lowest input lag. Without 'Game' mode enabled in 'PC' mode, the input lag with a 4k, 60Hz signal is 19.3ms.

The Samsung Q90T supports most common resolutions, and it can display proper chroma 4:4:4 at all resolutions except 1440p @ 120Hz. To display chroma 4:4:4, the input in use must be labelled 'PC' and Input Signal Plus must be enabled. For full-bandwidth signals like 4k @ 60Hz + HDR, Input Signal Plus also needs to be enabled.

The TV is advertised as being able to display a 4k @ 120Hz signal; however, we couldn't do so, even when using the same computer and settings that we had used for the Samsung Q90/Q90R QLED.

If you're looking for a TV that displays 8k content, look into the Samsung Q800T QLED.

The Samsung Q90T's frequency response is okay. It's reasonably well-balanced, and there's a good amount of punch in the bass. However, there's not enough bass extension to produce any rumble or thump. It gets very loud, making it suitable for large rooms and noisy environments, but there's quite a bit of compression when playing at max volume.

There's a room correction feature that tunes the sound according to your room's acoustics, and it's performed automatically when the Adaptive Sound+ setting is enabled within the Intelligent Mode Settings menu.
