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.
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.
The Samsung Q70T is decent for watching movies. Its high contrast ratio and remarkable black uniformity produce deep, inky blacks, which is ideal for watching movies in the dark. Unfortunately, it lacks local dimming to further improve black levels. That said, it upscales Blu-rays and lower-resolution content without issue.
The Samsung Q70T is good for watching TV shows. It performs well in well-lit rooms thanks to its high peak brightness and decent reflection handling. It also does a good job of upscaling lower-resolution content like cable TV. Unfortunately, it has poor viewing angles, so it's not well-suited to wide seating arrangements since the image looks washed out from the side.
The Samsung Q70T is decent for watching sports. Although its response time is only okay, it has a Black Frame Insertion feature to reduce motion blur. It provides good visibility in bright rooms, as it has decent reflection handling and gets bright enough to overcome glare. Unfortunately, its VA panel has poor viewing angles, so it's less suited for watching with a big group of people.
The Samsung Q70T is a good TV for video games. It has a remarkably low input lag that makes gaming feel responsive, and it has an okay response time. If you like gaming in the dark, its high contrast ratio makes blacks look deep and inky, but it lacks a local dimming feature to further improve the contrast. It also supports FreeSync to reduce screen tearing.
The Samsung Q70T is decent for watching HDR movies. It performs well in the dark, thanks to its fantastic contrast ratio and remarkable black uniformity. However, it doesn't have local dimming to further improve blacks. Unfortunately, while it has a wide color gamut, it can't get bright enough to make HDR content pop as it should.
The Samsung Q70T is good for HDR gaming, mostly due to its great gaming performance. It has an exceptionally low input lag with HDR and an okay response time. It also includes VRR support to reduce screen tearing, and its high contrast ratio is great for gaming in the dark. That said, it doesn't get bright enough to make HDR content really pop.
The Samsung Q70T is very good for use as a PC monitor. It can display proper chroma 4:4:4, so text looks clear and legible. It also has a remarkably low input lag, which makes for a responsive desktop experience. However, its VA panel has poor viewing angles, which means the image looks washed out at the edges when sitting up close.
Note: Samsung has shifted their lineup this year, so although this TV replaces the Samsung Q70/Q70R QLED by name in Samsung's lineup, it's more closely related to the Samsung Q60/Q60R QLED performance-wise.
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.
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.
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.

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.

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 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 always flickers at 240Hz, except when its Black Frame Insertion feature is enabled, reducing the flicker to 120Hz. 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'.
