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.
The Samsung Q90T is an excellent TV for most uses. Nearly every type of content looks good on this TV, whether it's a low-resolution cable TV show or a 4k HDR movie. It has a fast response time and low input lag, and it also comes with FreeSync support to reduce screen tearing when gaming. However, there's a bit of dirty screen effect, which can be somewhat distracting when watching sports.
The Samsung Q90T is great for watching movies. It has a high contrast ratio due to its VA panel, and it has full-array local dimming to make it even better. Black uniformity is good too, making this TV a fantastic choice for dark room viewing. The TV can remove judder from all sources, but lower frame rate content can stutter a bit.
The Samsung Q90T is excellent for watching TV shows. It can upscale lower-resolution content from cable TV well without any obvious artifacts. The TV is well-suited for bright rooms, as it has exceptional reflection handling and gets extremely bright. Viewing angles are decent, so you should be able to walk around while watching without losing much image accuracy.
The Samsung Q90T is great for watching sports. The TV has a great response time and an optional Black Frame Insertion feature, so there's very little blur in fast-moving scenes. It can get very bright to combat glare, it has exceptional reflection handling, and its decent viewing angles are great for watching a game with friends and family. Unfortunately, there's some dirty screen effect, which is rather disappointing.
The Samsung Q90T is amazing for playing video games. It has a fast response time that results in clear images with minimal motion blur, and it has a low input lag and FreeSync support. There's also an 'Automatic Low Latency Mode', making it easier to jump right into the game without having to change picture mode each time, which can be rather tedious. The TV's VA panel can produce deep blacks, which is great for those who like to game in the dark.
The Samsung Q90T is a great TV for watching movies in HDR. The TV can produce vibrant and vivid colors, and its excellent HDR peak brightness makes highlights pop. Its VA panel has a high contrast ratio and is further enhanced by its full-array local dimming. Its response time is great and motion blur is minimal, but it can also cause lower frame rate content to stutter at times.
The Samsung Q90T is excellent for gaming in HDR. On top of having a fast response time and low input lag, this TV can deliver a great HDR experience with its wide color gamut and high peak brightness. It's a great choice for dark room gaming, as it has a high contrast ratio that's boosted by full-array local dimming, and its black uniformity is good too, albeit with some minor blooming here and there.
The Samsung Q90T is excellent for use as a PC monitor. It has an amazingly low input lag to provide a responsive desktop experience, and it has a fast response time. Chroma 4:4:4 is displayed properly, which is great for text clarity, and there's no risk of permanent burn-in with static content such as a desktop user interface.
The Samsung Q90T is Samsung's flagship TV for their 2020 lineup of 4k QLED TVs. Since Samsung has shifted their lineup, this is a replacement of the Samsung Q80/Q80R QLED and not the Samsung Q90/Q90R QLED. There's a Q95T that's closer to the Q90R, as it still has the One Connect Box, but it's only available in Europe. The Q90T's main competitors are the LG BX OLED, the Sony X950H, and the Vizio P Series Quantum X 2020.
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.
The stand is a heavy piece of metal that feels solid. There's a bit of wobble, mainly due to the stand being center-mounted.
Footprint of the 55 inch stand: 11.9" x 9.3"
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.
The bezels on the Samsung Q90T are very thin and shouldn't be distracting.
The TV has a slightly boxier profile than the Samsung Q90/Q90R QLED, but it's still very thin and shouldn't stick out much when wall-mounted. Sadly, it isn't compatible with Samsung's no-gap wall mount.
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.
Like most VA panels, the Samsung Q90T has an excellent native contrast ratio, and it improves significantly with local dimming enabled, allowing it to produce deep blacks. Note that the contrast ratio can vary between units.
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.
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.
Amazing 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.
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.
Black uniformity is good; however, this can vary between units. Without local dimming, there's a bit of clouding throughout the screen, as well as some blooming around the test cross. With local dimming enabled, the clouding is less visible, but blooming around the test cross is more intense.
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.
Outstanding reflection handling. It performs exactly like the Samsung Q80/Q80T QLED, and you shouldn't have any issues using this TV in a very bright room.
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.
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.
You can see our recommended settings here.
The Samsung Q90T upscales 720p content like cable TV well and it looks almost identical to its predecessor, the Samsung Q90/Q90R QLED.
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.
Good color volume. The TV can display dark and saturated colors well due to its high contrast ratio, but like most LED TVs, it can't reproduce bright blues all that well. This is slightly inferior to the Samsung Q90/Q90R QLED.
Excellent gradient performance. There's still some visible banding when displaying reds and greens, and a little bit in grays as well. If banding bothers you, enabling Noise Reduction can help, but it may cause the loss of fine details in some scenes.
As is the case with most VA panels, the Samsung Q90T doesn't show any signs of temporary image retention. However, image retention can vary between units.
We don't expect VA panels to experience burn-in, as the VA panel in our long-term test appears immune.
The Samsung Q90T's response time is great. There's very little blur trail in fast-moving scenes; however, there's also a significant amount of overshoot in the 0-20% transition, resulting in the appearance of some artifacts.
The backlight isn't flicker-free, but since it flickers at such a high frequency, it shouldn't be noticeable for most people. That said, the flickering drops to 120Hz when in 'Dynamic', 'Standard', 'Natural', or 'Game' mode. In addition, the flickering is also at 120Hz when Picture Clarity is enabled.
The Samsung Q90T has an optional Black Frame Insertion feature that can help improve motion clarity. To use it in 60fps content, enable LED Clear Motion in the Picture Clarity settings menu. For 120fps content, simply enable the Picture Clarity setting without adjusting any of the sliders.
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.
Due to the Samsung Q90T's fast response time, lower frame rate content can appear to stutter as each frame is held on for longer. If the stuttering bothers you, enabling Picture Clarity or LED Clear Motion can help.
The Samsung Q90T can remove judder from all sources. It plays most content without judder even when Picture Clarity is disabled, but it isn't always perfect. Enabling Picture Clarity removes any remaining judder that may occur.
