The Samsung Q70/Q70T QLED is a good all-around 4k TV from Samsung's 2020 QLED lineup. It delivers good performance for most uses and comes with some extra features like variable refresh rate (VRR) support to reduce screen tearing in games. The TV has a high 120Hz refresh rate and an okay response time. There's a Black Frame Insertion feature to help reduce motion blur. It also has an incredibly low input lag, making for a responsive gaming experience. The TV uses a VA panel with a fantastic contrast ratio and remarkable black uniformity, producing deep inky blacks even though it lacks a local dimming feature. Unfortunately, it has poor viewing angles, so the image looks washed out from the side, but this is typical of TVs with VA panels. While it gets bright enough to combat glare and has decent reflection handling for well-lit rooms, it can't get bright enough to deliver a truly satisfying HDR experience.
Our Verdict
The Samsung Q70T is a decent TV for a variety of uses. Its high contrast ratio and remarkable black uniformity deliver good dark room performance, whether using it to watch movies or play video games. It's not ideal for watch TV or sports with large groups because it has poor viewing angles, but it gets bright enough to overcome glare in well-lit rooms. Sadly, its HDR experience is a little underwhelming because it can't get bright enough to make highlights pop.

If someone comes across a different type of panel or if their Samsung Q70T doesn't correspond to our review, let us know and we will update the review. Note that some tests, like gray uniformity, can vary between individual units.
Our unit of the QN55Q70T was manufactured in February 2020; you can see the label here.
Compared To Other TVs
The Samsung Q70T is a good TV for most uses, but it doesn't perform as well as the Samsung Q70/Q70R QLED. It lacks a local dimming feature and has a lower peak brightness. Its response time is also slower, but on the upside, it comes with eARC support. For other options, check out our recommendations for the best TVs, the best HDR gaming TVs, and the best smart TVs.
The Samsung Q80/Q80T QLED is better than the Samsung Q70/Q70T QLED for most uses. The Q80T has a full-array local dimming feature, can get brighter in HDR, and has much wider viewing angles. The Q80T also has better color accuracy and a faster response time, but due to its 'Ultra Viewing Angle' layer, its contrast ratio is much lower than the Q70T, making blacks look a bit more grayish.
The Samsung Q70/Q70T QLED and The Samsung Q60/Q60T QLED are very similar TVs in many respects. The main difference is that the Q70T has a faster response time and a higher refresh rate, so motion looks smoother. Also, the Q60T can't remove judder from every source and it doesn't support VRR. Gradient handling on the Q60T isn't as good, but it has better color accuracy, which is great if you don't plan on calibrating your TV.
The Samsung Q70/Q70T QLED directly replaces the Samsung Q70/Q70R QLED from 2019. The Q70T is a bit of a step down, as it doesn't perform as well and lacks a local dimming feature, which the Q70R has. The Q70T also has a slower response time, leading to more motion blur, and it has a significantly lower peak brightness. The Q70T doesn't feel as well-built as the Q70R, but you get eARC support on the Q70T, and it has a lower input lag.
Overall, the Sony X900H performs better than the Samsung Q70/Q70T QLED. The Sony has full-array local dimming, and it has a much better response time, resulting in smoother motion. The Sony also feels better built. That said, the Samsung has a much better contrast ratio, which delivers deeper blacks.
The LG NANO90 2021 is slightly better overall than the Samsung Q70/Q70T QLED, but they have different panel types. The LG has an IPS panel with wider viewing angles, while the Samsung has a VA panel with better contrast for improved black levels. The Samsung is better for watching HDR content because it displays a wider color gamut, and despite not having a local dimming feature, it has improved dark room performance. On the other hand, the LG is a better choice for watching shows or sports because it has much better reflection handling, and it has a much quicker response time for smoother motion.
The Samsung Q70/Q70A QLED is the successor to the Samsung Q70/Q70T QLED, and while it offers a couple of improvements, it's not as big of a step up as you might expect. The biggest improvement is its response time. The Q70T has an okay response time but is likely not good enough for more competitive gamers, whereas the Q70A is significantly faster, resulting in less motion blur. The Q70A also gets a bit brighter in HDR, resulting in a better overall HDR experience, and its backlight flickers at a much higher frequency than the Q70T's, which is good news for those who are sensitive to flicker.
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.
The Samsung Q70/Q70T QLED and the Samsung Q60/Q60R QLED are very similar in terms of performance and features. The Q70T is marginally better, as it has much better gray uniformity and black uniformity, and it has a lower input lag. However, the Q60R has a faster response time and better color accuracy. Other than that, these two TVs perform very similarly, except that the 43" and 49" of the Q60R have a 60Hz panel and don't support any VRR technology.
The Samsung Q80/Q80R QLED outperforms the Samsung Q70/Q70T QLED in almost every category. The Q80R looks and feels better-built, has local dimming, can get much brighter, especially with HDR content, has much better viewing angles, handles reflections much better, has much better motion handling, and has a wider color gamut. Its biggest disadvantage is that its contrast ratio isn't quite as high as the Q70T.
The Sony X950H performs better overall than the Samsung Q70/Q70T QLED. While the Sony doesn't have a contrast ratio as high as the Samsung's, it has better viewing angles, gets much brighter, and can deliver a true HDR experience. The Sony also has a much faster response time for smoother motion handling.
The TCL 6 Series/R635 2020 QLED is better overall than the Samsung Q70/Q70T QLED. The TCL is a flagship model that gets much brighter than the Samsung, delivering a much better HDR experience. It also has a local dimming feature, which the Samsung doesn't have, but it doesn't perform very well on the TCL. They each have a 120Hz panel with VRR support, but with HDMI 2.1 support on the Samsung, it allows for 4k @ 120Hz gaming with both the PS5 and Xbox Series X.
The Sony X800H and the Samsung Q70/Q70T QLED are both decent TVs but use different panel types. The VA panel on the Samsung has a much better contrast ratio to display deeper blacks. It has an HDMI 2.1 input, so it supports 4k @ 120Hz content, and it also has VRR support. On the other hand, the IPS panel on the Sony has much wider viewing angles, and despite having a 60Hz panel, it has a quicker response time for smoother motion.
The Samsung The Frame 2020 and the Samsung Q70/Q70T QLED perform similarly overall. The biggest difference is that the Frame is designed to look like a framed piece of art, so if you're looking for a TV with a unique design, it may be the better option. However, if you're looking for a standard TV, and you can forgive the slower response time, the Q70T may be preferable.
For most uses, the Vizio P Series Quantum 2020 is better than the Samsung Q70/Q70T QLED. The Vizio has local dimming, which the Samsung doesn't have, and it gets a lot brighter in SDR and HDR. It also has a much better HDR color gamut and faster response time. However, the Samsung has a higher contrast ratio and a lower input lag.
The LG GX OLED is much better than the Samsung Q70/Q70T QLED, but each TV has a different panel type. The LG's OLED panel allows it to display perfect blacks and has much wider viewing angles as well. The LG also has a quicker response time and lower input lag for a better gaming experience. However, the Samsung gets brighter in SDR, so it can combat glare in well-lit rooms, and it doesn't have the risk of permanent burn-in.
The Samsung Q70/Q70T QLED and the LG NANO90 2020 are both good TVs with different panel types. The Samsung has a VA panel that allows it to display much deeper blacks than the LG, so it's better suited for watching movies in dark rooms. However, the LG's IPS panel has wider viewing angles, making it a better choice for wide seating areas.
The Samsung Q70/Q70T QLED is a bit better than the LG NANO85 2020, but they use different panel types. The Samsung uses a VA panel, so it has a much better contrast ratio, while the LG has wider viewing angles thanks to its IPS panel. The Samsung gets brighter, has a lower input lag, and supports FreeSync VRR, but the NANO85 has a quicker response time.
The Samsung Q70/Q70T QLED is better overall than the Samsung TU8000. The Q70T has more features such as VRR support for gaming, a 120Hz panel, and it displays a wider color gamut for HDR content. The Q70T also gets much brighter, allowing it to combat glare in well-lit rooms.
The Hisense H9F is better overall than the Samsung Q70/Q70T QLED. The Hisense can deliver a far better HDR experience due to its impressive peak brightness and wide color gamut. Also, the Hisense has a faster response time and much better reflection handling, but the Samsung has better out-of-the-box color accuracy and it supports FreeSync to reduce screen tearing when gaming.
The Sony X950G is a better TV than the Samsung Q70/Q70T QLED. The Sony has a much better build quality, a higher peak brightness, and is one of the most color-accurate TVs we've tested. Motion handling is significantly better on the Sony, and it has a local dimming feature. However, the Samsung has a higher native contrast ratio and it supports FreeSync, which may be important to some gamers. The Samsung has better gray uniformity, which is good if you watch a lot of sports.

Test Results
The Samsung Q70T has an excellent design that's very similar to the Samsung Q70/Q70R QLED, as well as its smaller sibling, the Samsung Q60/Q60T QLED. It's minimalist, with very thin bezels and wide-set feet, and it comes with clips for cable management.
The stand is simple and supports the TV well, but there's still a bit of wobble when nudged. The feet are wide-set and point outwards, so it requires a fairly large table to put it on if you don't plan on wall-mounting it. They no longer need to be screwed in, as you only need to slide them into place, making the setup process much easier. Unfortunately, they're not reversible.
Footprint of the 55 inch stand: 40.3" x 9.5".
The back of the TV is fully plastic and has a horizontal dotted pattern etched into it. All the inputs are side-facing, making them easy to access even when the TV is wall-mounted. There are clips to attach the cables to the back of the stand for cable management.
The TV is thin and shouldn't stick out much when wall-mounted.
The TV feels decently built. Despite its all-plastic construction, there are no obvious gaps, and you shouldn't have issues with it. However, the TV still wobbles a bit.
The Samsung Q70T has an outstanding contrast ratio, capable of producing deep blacks. Unfortunately, it doesn't have a local dimming feature to further improve it. Note that the contrast ratio can vary between individual units.
Update 07/13/2021: We retested the peak brightness with the latest firmware (2014.1). Some scenes are a bit brighter than before, but overall it's within the same ballpark.
Great SDR peak brightness. It can get bright enough to fight glare in most rooms and is fairly consistent when displaying different content. The 2% window is significantly darker due to the TV's CE (frame) dimming, which can't be disabled and may make dark scenes appear darker than they should.
We measured the SDR peak brightness after calibration in the 'Movie' Picture Mode, with Brightness set to maximum, Gamma set to '2.2', Contrast at its default value, and Contrast Enhancer set to 'Medium'.
If you don't mind losing image accuracy, you can get a brighter image by setting the Picture Mode to 'Vivid', with Brightness and Contrast set to max, and Contrast Enhancer set to 'Medium'. These settings allowed us to achieve 515 cd/m² in the 10% window.
Update 07/13/2021: We've added two new videos demonstrating the backlight behavior with real content.
The Samsung Q70T doesn't have a local dimming feature. The video above is provided for reference only.
Update 07/13/2021: We've added two new videos demonstrating the backlight behavior with real content.
The Samsung Q70T doesn't have a local dimming feature. The video above is provided for reference only.
Mediocre HDR peak brightness. Again, except for the darker 2% window caused by the TV's CE dimming, the brightness doesn't vary much when displaying different content. It can deliver an okay HDR experience in a dark room, but it doesn't look significantly different from SDR content in brighter environments.
We measured the HDR peak brightness in the 'Movie HDR' Picture Mode, with Brightness and Contrast set to maximum.
If you want a brighter image in HDR and don't mind losing a bit of accuracy, set the Picture Mode to 'Movie HDR', with Brightness and Contrast set to max, and Contrast Enhancer set to 'Medium'. These settings allowed us to achieve 524 cd/m² in the 10% window.
If you want a TV that can get brighter to deliver a better HDR experience, take a look at the Vizio P Series Quantum 2020.
Gray uniformity is good, but this can vary between individual units. It's slightly darker around the sides of the screen, but thankfully, there's very little dirty screen effect, and uniformity is much better in darker scenes.
Black uniformity is remarkable. There's a bit of backlight bleed around the top corners of the screen, as well as some minor clouding and blooming around the test cross, but the rest of the screen is very uniform. Note that black uniformity can vary between units.
Like most TVs with VA panels, the Samsung Q70T has poor viewing angles. Images look washed out from the side, making it less suited to large rooms and wide seating arrangements.
Update 03/01/2021: We remeasured the total reflections because there was a mistake with our original testing. The final scoring hasn't changed.
The Samsung Q70T has decent reflection handling. It's similar to the Samsung Q70/Q70R QLED, except that it's slightly better at reducing the intensity of reflected light. Visibility should be fine in most rooms, but it may be an issue in rooms with a lot of windows.
Out of the box, the Samsung Q70T has great color accuracy, but accuracy can vary between units. There are minor inaccuracies with several colors and with shades of gray, although they may be difficult to notice. Gamma doesn't follow the 2.2 target at all, resulting in most scenes appearing brighter than they should. The color temperature is on the warm side, giving the image a slight reddish tint.
Update 09/30/2020: We've changed the status of the Auto-Calibration function from 'Untested' to 'Undetermined', as the Q70T isn't yet listed as being compatible with CalMAN.
After calibration, color accuracy is outstanding. White balance and gamma are near perfect, and the color temperature is very close to our target of 6500K. However, there are still some inaccuracies with a few colors. This is because when we tried to change any color settings, it made it significantly worse and introduced clipping. That said, most of these inaccuracies are very difficult to notice without the aid of a colorimeter.
You can see our recommended settings here.
The Samsung Q70T uses a BGR sub-pixel structure. It doesn't affect image quality, but it can affect text clarity when using the TV as a PC monitor. You can read more about it here.
The Samsung Q70T has a good HDR color gamut. It has excellent coverage of the widely used DCI P3 color space, but its coverage of the wider Rec. 2020 is mediocre. The 'Movie' EOTF follows the target curve fairly well until the roll-off, although 'Game' mode appears darker in general, as you can see here.
If you find HDR too dim, you can make it brighter by setting Brightness and Contrast to maximum, set ST.2084 to maximum, and set Contrast Enhancer to medium.
You can also check out our recommended settings here.
The Samsung Q70T has okay color volume but not as good as the Samsung Q70/Q70R QLED. It can produce dark colors well due to its high contrast ratio, but like most LED TVs, it doesn't display very bright blues well.
Great gradient performance. There's some very minor banding in darker shades, although it shouldn't be noticeable in most content. If banding bothers you, enabling Noise Reduction can help a bit but at the cost of some fine details in some scenes.
Like most VA panels, the Samsung Q70T shows no signs of temporary image retention, although this can vary between individual units.
We don't expect VA panels to experience burn-in, as the VA panel in our long-term test appears immune.
Update 03/01/2021: We updated the TV to the latest firmware and the flicker frequency dropped from 600Hz to 240Hz. We retook the response time photo with the lower flicker frequency.
The Samsung Q70T has an okay response time. There's a bit of blur trail behind fast-moving objects, and the 0-20% transition is a bit slow, resulting in slightly more motion blur in darker scenes.
If you want a TV with a better response time, check out the Samsung Q80/Q80T QLED.
Update 07/13/2021: We retested the backlight flicker with the latest firmware (2014.1), and found that the flicker behaves a bit differently now. The Samsung Q70T now flickers at 240Hz in Filmmaker, Movie, or Game mode, but flickers at 120Hz in all other modes.
Update 03/01/2021: We updated the TV to the latest firmware and retested the flicker frequency. It flickers at 240Hz, and not 600Hz.
The Samsung Q70T uses Pulse-Width Modulation (PWM) to dim the backlight. It flickers at 240Hz in Game, Movie, or Filmmaker modes, and at 120Hz in all other modes. Also, it flickers at 120Hz when in 'PC' mode (without 'Game' mode) and when in 'Game' mode with Game Motion Plus enabled.
Update 08/11/2020: A previous version of the review stated the BFI had a minimum flicker of 120Hz for 60fps content in 'Game' mode. It flickers at 60Hz in 'Game' mode with Game Motion Plus and LED Clear Motion enabled. The review has been updated.
Update 07/27/2020: We retested the flicker frequency with Game mode on or off.
The Samsung Q70T has an optional Black Frame Insertion feature that can help reduce motion blur. Unfortunately, the timing is quite off, causing visible image duplication.
With 120fps content, the backlight always flickers at 120Hz, and you can't change the LED Clear Motion settings. It flickers at 240Hz outside of 'PC' mode with 'Game' mode off. With 'Game' mode on, it flickers at 120Hz, and goes down to 60Hz with LED Clear Motion and Game Motion Plus enabled. Enabling LED Clear Motion outside of 'Game' mode also reduces the flicker to 60Hz.
Update 06/04/2020: We've retested the Blur Reduction bug with the new firmware update (1113), and we can confirm that the TV can interpolate 30fps and 60fps content up to 120fps.
This TV can interpolate lower frame rate content up to 120Hz. To enable it, you have to set Picture Clarity to 'On', set Judder Reduction to '10' for 30fps, and Blur Reduction to '10' for 60fps content.
With motion interpolation enabled, there's noticeable duplication in fast scenes, and it introduces a good amount of artifacts when displaying more intense scenes.
The Samsung Q70T displays lower frame rate content without much stutter due to its slower response time. It can still happen at times, but if it bothers you, enabling Picture Clarity can help.
The Samsung Q70T can remove judder from all sources. To use it, set Picture Clarity to 'Custom', but leave the Blur Reduction and Judder Reduction sliders to '0'.
Update 11/18/2020: We've retested the VRR with an HDMI 2.1 source and firmware version 1403. It can now display 120fps at 4k 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 Q70T supports FreeSync to reduce screen tearing when gaming. It turns on automatically when the TV detects a computer or an Xbox One that has VRR enabled at the launch of a game.
Update 11/18/2020: We've retested the input lag with an HDMI 2.1 source and firmware version 1403. We've added the 4k @ 120Hz input lag, which is measured in 'Game' mode with chroma 4:4:4 and 8-bit color coding. We've also updated the input lag for the other resolutions.
The TV has an incredibly low input lag as long as 'Game' mode is enabled. It's slightly higher when VRR or Game Motion Plus are enabled, as well as when playing at 4k @ 60Hz + HDR. However, it shouldn't be noticeable for most casual gamers. To get the lowest input lag when using the TV as a PC monitor, set the icon for the input in use to 'PC'.
Update 11/18/2020:We've retested the supported resolutions with an HDMI 2.1 source and firmware version 1403. It can now display 4k @ 120Hz properly.
Update 06/04/2020: We've retested the TV with the newest firmware (1113), and we still can't display a 4k @ 120Hz signal.
This TV supports most common resolutions. It can display proper chroma 4:4:4 in all resolutions except 1440p @ 120Hz. To display chroma 4:4:4, the input must be labeled 'PC', and for high bandwidth signals like 4k @ 60Hz + HDR, the Input Signal Plus setting must be enabled for the port in use. Game Motion Plus can't be used when VRR is enabled.
Update 05/19/2021: After a PS5 software update, Samsung TVs can now display 4k @ 120Hz in HDR.
This TV supports all common resolutions from both the PS5 and Xbox Series X without any issue.
Update 11/18/2020: We've retested the inputs with an HDMI 2.1 source and firmware version 1403. We can confirm that only the HDMI 4 port supports HDMI 2.1, and it has the full HDMI 2.1 class bandwidth.
The TV supports eARC, allowing it to pass high-quality object-based audio like Dolby Atmos via TrueHD over an HDMI connection. To use it, set HDMI eARC to 'Auto' and Digital Output Audio to 'Auto' or 'Passthrough'.
Decent frequency response. We tested the TV with Samsung's Intelligent Adaptive Sound+ feature enabled, and it sounds okay. It's fairly well-balanced, but it can't really produce a deep, rumbling sound. It gets reasonably loud, more so than the Samsung Q70/Q70R QLED.
This TV has a mediocre distortion performance. It's passable when playing at moderate volume levels, but there's a fair amount of distortion at higher levels. That said, distortion depends on the content and some people may not hear it.
Like all Samsung TVs, the Samsung Q70T runs on Tizen OS. It's easy to use and runs smoothly for the most part, but there's still a bug when changing the input from 'PC' to something else, causing the edges of the screen to appear cut off due to overscan. You can resolve this issue by navigating into the Picture Size setting and by enabling 16:9 and 'Fit to Screen'.
Unfortunately, there are ads and suggested content on the home page and within the app store, and they can't be disabled.
Samsung's app store has a large selection of apps, and they run fairly smoothly. You can also cast content to the TV using a mobile device, and the built-in media app supports most common file types.
The TV comes with the same remote as other Samsung QLED TVs. It has a built-in mic for voice control through Samsung's Bixby and shortcuts for Netflix, Amazon Prime Video, and Samsung TV Plus.
The TV's controls are located at the center, beneath the Samsung branding. It's a single button that lets you turn the TV On/Off, as well as changing the channel, volume, and input.
