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.

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.

Design
Stand

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".

Design
Back
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.

Thickness
Max Thickness 2.20" (5.6 cm)

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

Design
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.

Contrast
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.

Backlight
Full-Array

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.

The Q80T's black uniformity is great. There's a bit of clouding throughout the screen and the overall image looks a bit more grayish. With local dimming enabled, the clouding is less noticeable, but it makes the blooming around the test cross much more visible.

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.

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

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.

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.

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.
