The Samsung Q80T is a great TV for most content, delivering crisp images with its fast response time, as well as a good HDR experience with its wide color gamut and high peak brightness. It has a great native contrast ratio that's boosted by a full-array local dimming, and its excellent color accuracy means you likely won't need to calibrate it. Viewing angles are decent due to Samsung's 'Ultra Viewing Angle' layer, making it suitable for moderately large rooms, and it can get bright enough to fight glare in nearly any type of setting. Input lag is extremely low, it has a 120Hz refresh rate, and to top it all off, it has support for variable refresh rate technology to reduce screen tearing. The screen has some minor uniformity issues that can be distracting for some, but as a whole, this is a great choice regardless of the content that you watch.

The Samsung Q80T is a mid-range TV in Samsung's high-end 4k QLED TV lineup. It sits below the flagship Samsung Q90T and above the Samsung Q70T. Since Samsung has shifted their entire lineup this year, this is a replacement of the Samsung Q80/Q80R QLED in name only, as its performance and features are closer to that of the Samsung Q70/Q70R QLED. We expect its main competitors to be the LG BX OLED and the Sony X950H.

Curved No

The Samsung Q80T has an excellent design that's simple and minimal. It has thin bezels on all sides and its pedestal-style stand is center-mounted.


The stand is a mix of metal and plastic. It provides decent support for the TV but there's still a fair amount of wobble. Luckily, it's fairly small and doesn't take up much space, making it easier to place a soundbar in front.

Footprint of the 55" stand: 15.4" x 10.3".

Wall Mount VESA 200x200

The back of the TV is plastic and it's plain except for the fine horizontal texture etched into it. The inputs are side-facing and are easily accessible when the TV is wall-mounted, and there are grooves that guide the cables towards the stand, which is hollow and serves as cable management.

Borders 0.35" (0.9 cm)

The bezels on the Q80T are thin and aren't distracting.

Max Thickness 2.20" (5.6 cm)

The TV is quite thin without the stand and shouldn't stick out much when wall-mounted.

Build Quality

Build quality is excellent. It's mostly plastic, but it feels well-built and sturdy overall. The TV does wobble when nudged; mostly due to the design of the stand.

Native Contrast
3042 : 1
Contrast with local dimming
4225 : 1

The Samsung Q80T has a great native contrast ratio; however, it's lower than models from previous years. This is likely due to the new implementation of Samsung's 'Ultra Viewing Angle' layer, which improves viewing angles at the expense of contrast ratio. The contrast does improve when local dimming is enabled, but blacks can still appear grayish in some scenes.

Note that the 49" variant doesn't have the 'Ultra Viewing Angle' layer and is expected to have a higher native contrast ratio.

Picture Quality
Local Dimming
Local Dimming

This TV has a decent full-array local dimming feature. The implementation has been tweaked to light up more zones at once, which has the effect of reducing intense blooming around bright objects but also causes a larger section of the screen to appear grayish. That said, it isn't as noticeable in real content, and subtitles are handled well. It's still a bit slow in reacting to changes and can sometimes cause the corners of the screen to flash when the whole screen is gray. The performance is very close to that of the Sony X900F.

The Q80T has an impressive SDR peak brightness. It's more than enough to fight glare in bright rooms, but there's quite a bit of variance in brightness when displaying different content.

We measured the peak brightness after calibration, using the 'Movie' Picture Mode, with Brightness set to maximum, and Local Dimming set to 'High'.

Good HDR peak brightness. This TV can deliver a very good HDR experience, especially if you're watching in a dark to moderately-lit room.

We measured the HDR peak brightness before calibration, using the 'Movie HDR' Picture Mode, with Local Dimming set to 'High', and all other image processing disabled.

If you want a TV with higher HDR peak brightness, check out the Sony X950H.

The Q80T has decent viewing angles for a VA panel TV. It has Samsung's 'Ultra Viewing Angle' layer, which improves viewing angles at the cost of contrast ratio. Gamma shift happens rather quickly once you move off-center, but black level remains fairly consistent until you reach moderate viewing angles. To take our measurements, we had to perform two runs, one with local dimming set to 'Low' to measure color, and the other with local dimming disabled to measure lightness, black level, and gamma. Overall, viewing angles are better with the local dimming disabled.

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.

Note that the 49" variant of this TV doesn't have the 'Ultra Viewing Angle' layer and we expect it to have worse viewing angles.

Outstanding reflection handling. The screen's anti-reflective coating performs remarkably well at reducing the intensity of reflected light, making it a great choice for bright rooms. It performs very similarly to the Samsung Q80/Q80R QLED, but with less scattering of the reflection, likely due to the TV's new 'Ultra Viewing Angle' layer.

The Q80T has excellent color accuracy out-of-the-box. There are only minor inaccuracies that are very difficult to spot with the naked eye and white balance is also fantastic. However, the color temperature is a bit on the warm side and gamma doesn't follow the target all that well, causing most scenes to appear brighter than they should.

Auto-Calibration Function

Update 09/30/2020: We've changed the status of the Auto-Calibration function from 'Untested' to 'Undetermined', as the Q80T isn't yet listed as being compatible with CalMAN.

After calibration, color accuracy is superb. White balance, gamma, and color temperature are right on target, and any remaining inaccuracies shouldn't be noticeable without the aid of a colorimeter.

You can see our recommended settings here.

Picture Quality
480p Input

480p content like DVDs is upscaled without any obvious artifacts and it looks very similar, if not identical to the Samsung Q70R and the Samsung Q70T.

Picture Quality
720p Input

720p content such as cable TV is upscaled well, with no signs of upscaling artifacts.

Picture Quality
1080p Input

The Q80T has no issues upscaling 1080p content.

Picture Quality
4k Input

Native 4k content is displayed perfectly.

Picture Quality
8k Input

The Q80T can't display an 8k signal.

Picture Quality

The pixels on the Q80T are a bit blurry due to the 'Ultra Viewing Angle' layer. It is, however, much clearer than what we had observed on the Samsung Q80/Q80R QLED, indicating that this is a new implementation of the technology. You can also see the filter in this photo.

The Q80T has a great color gamut. It has excellent coverage of the DCI P3 color space, which is used for most HDR content, and it has decent coverage of the wider Rec 2020 color space. The 'Movie' EOTF is slightly too bright for the most part until the roll-off, and the 'Game' mode EOTF is a little too dark in some scenes, 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 'High'. Using these settings, you can make HDR appear significantly brighter, as you can see in this EOTF

If you want a TV with a better HDR color gamut, check out the Vizio P Series Quantum X 2020.

Very good gradient performance. The most visible banding is with the color green, but there's also some fine banding when displaying shades of gray, red, and blue. If this bothers you, enabling Noise Reduction in the Picture Clarity Settings menu can remove most of it; however, it may cause the loss of some fine details.

We don't expect VA panels to experience burn-in, as the VA panel in our long-term test appears immune.

Response Time

The Q80T has an excellent response time. There should be very little blur trail behind fast-moving objects; however, there's significant overshoot in some transitions, which is more visible when using the motion interpolation feature to interpolate up to 120Hz.

If you want an even quicker response time, check out the LG CX OLED.

PWM Dimming Frequency
960 Hz

This TV uses Pulse-Width Modulation (PWM) to dim its backlight, but since it flickers at such a high frequency, it shouldn't be noticeable for most people. In 'Movie' mode, the flickering frequency drops to 120Hz when Picture Clarity is set to 'Custom' or 'Auto'. The flickering is also at 120Hz when using the 'Dynamic', 'Standard', 'Natural', or 'Game' mode.

Min Flicker for 60 fps in Game Mode
60 Hz

This TV has an optional black frame insertion feature that can help reduce motion blur, called LED Clear Motion.

Just enabling Picture Clarity lowers the flickering frequency to 120Hz, and turning on LED Clear Motion reduces the flickering further to 60Hz.

In 'Game' mode, the flickering is always at 120Hz, and enabling LED Clear Motion in the Game Motion Plus Settings menu lowers the flickering frequency to 60Hz.

Motion Interpolation
Motion Interpolation (30 fps)
Motion Interpolation (60 fps)

The Q80T can interpolate lower frame rate content up to 120Hz and it works remarkably well. There's very little artifacts in regular content, even in intense scenes. To use it, you must set Picture Clarity to 'Custom', set Judder Reduction to 10 for 30fps content, and set Blur Reduction to 10 for 60fps content.

Frame Hold Time @ 24 fps
31.6 ms
Frame Hold Time @ 60 fps
6.6 ms

Due to the TV's fast response time, lower frame rate content can appear to stutter, as each frame is held on for a longer period. If this bothers you, enabling Picture Clarity or LED Clear Motion can help.

24p Judder
Judder-Free 24p
Judder-Free 24p via 60p

Judder-Free 24p via Native Apps

The Q80T can remove judder from all sources. You can do so by setting Picture Clarity to 'Custom', and leaving Blur Reduction and Judder Reduction sliders at '0'.

Note that the 49" variant of this TV likely can't remove any judder at all.
