The Samsung Q70/Q70A QLED is a good overall 4k TV. It improves upon its predecessor, the Samsung Q70/Q70T QLED, in a couple of ways, most notably its significantly faster response time, which delivers a smooth gaming experience. It also supports FreeSync variable refresh rate (VRR) and has an incredibly low input lag. While it lacks local dimming, it has an exceptionally high native contrast ratio, so it produces deep blacks that look great in the dark. It gets bright enough to overcome glare in most lighting conditions, but it's best to avoid placing it in direct sunlight because it doesn't diffuse direct light very well. It's decent for HDR thanks to its wide color gamut, but it can't get bright enough to bring out the brightest highlights. Unfortunately, like most VA panels, it has narrow viewing angles, so the image looks washed out from the side.
The Samsung Q70 is good for mixed usage. Thanks to its high contrast ratio, it's good for watching movies or gaming in the dark, but it's also suited to well-lit rooms, as it gets bright enough to overcome glare. Its fast response time delivers smooth motion in content like sports and video games, and its low input lag makes it feel response when gaming or connected to a PC. HDR looks decent, but it doesn't get bright enough to bring out the brightest highlights.
The Samsung Q70 is decent for watching movies. While it doesn't have a local dimming feature, its native contrast is high enough to produce deep blacks that are ideal for watching movies in a dark room. It also removes 24p judder automatically and has no issues upscaling DVDs or Blu-rays. That said, its fast response time can cause low frame rate content to stutter.
The Samsung Q70 is good for TV shows. It gets bright enough to overcome glare in most rooms, despite only having decent reflection handling. Unfortunately, it has narrow viewing angles, so you lose image accuracy from the side. That said, it has no issues upscaling cable TV and Tizen OS gives you access to most popular streaming apps.
The Samsung Q70 is good for watching sports. It has an impressive response time, so motion looks smooth in fast-moving content. It gets bright enough to overcome glare in most rooms, too. That said, it has narrow viewing angles, so it's not ideal if you want to watch the game with a big group. You may also notice some dirty screen effect, which can be distracting during sports.
The Samsung Q70 is very good for playing video games. Its impressive response time delivers a clear image with minimal motion blur, and it has an incredibly low input lag. It also supports FreeSync to reduce screen tearing. It can do 4k @ 120Hz without issues, but some people may be disappointed that there's only one HDMI 2.1 port.
The Samsung Q70 is decent for watching movies in HDR. It's helped by its exceptionally high contrast ratio, although it lacks local dimming. It also has a wide color gamut for HDR. However, its HDR brightness is a bit lacking, so the brightest highlights don't quite pop as they should.
The Samsung Q70 is good for HDR gaming, mostly due to its gaming performance. The fast response time, low input lag, and VRR support deliver a smooth and a responsive gaming experience. However, its HDR brightness in 'Game Mode' is only okay, so the brightest highlights may not pop as they should. On the upside, it supports all common resolutions for advanced consoles.
The Samsung Q70 is great for use as a PC monitor. It can display proper chroma 4:4:4 for all resolutions except 1440p, which is important for text clarity. It also has an incredibly low input lag and fast response time. However, its narrow viewing angles can make the edges of the screen look washed out if you're sitting up close.
The Samsung Q70 is the mid-range model in Samsung’s 2021 4k QLED lineup, sitting above the Samsung Q60/Q60A QLED and below the Samsung Q80/Q80A QLED, as well as higher-end Neo QLEDs like the Samsung QN85A QLED and the Samsung QN90A QLED. It competes with models like the Sony X85J, the 2021 LG NANO80, and the Vizio P Series Quantum 2020.
Samsung’s 2021 QLEDs are all very thin and sleek-looking, and this one is no exception. It’ll look great in any living room. The stand is a new design for Samsung that's different than the Samsung Q60/Q60A QLED and the Samsung Q80/Q80A QLED. It's center-mounted, so it can also fit on smaller tables.
The stand looks a little cheap, but it supports the TV well for the most part, and it's center-mounted, so you can place it on a smaller table if you like.
Footprint of the stand: 11.9" x 9.8"
There are tracks along the back of the TV and the stand for cable management. The back is plastic with fine horizontal etchings to give it a brushed aluminum look.
The TV is very thin. It should sit flush against the wall when wall-mounted, and the inputs are side-facing for easy access.
It feels well-built overall, despite some wobble due to the thin profile and narrow stand. There’s a bit of a gap around the border. Our unit arrived with some slight damage, as the bottom-left part of the border pops out a bit in a way it shouldn't, making it feel less solidly put together. This is just a defect with our unit alone, though, so it doesn't affect scoring and shouldn't be present on other units. The stand feels somewhat cheap, but it has a plastic cover that slides in to cover the two feet.
The Samsung Q70 has a fantastic contrast ratio, but this can vary a little between units. It’s among the highest native contrast ratios we’ve tested on an LED TV, which is a good thing considering it doesn’t have a local dimming feature.
It gets very bright overall. It’s not as bright as the brightest LED TVs, like the Samsung QN90A QLED, but it’s better than average, so it’s able to overcome glare in most lighting conditions.
We measured SDR brightness after calibration, using the ‘Movie’ Picture Mode, with Brightness set to max, and Color Tone set to ‘Warm2’.
To get an ever brighter image, you can try setting the Picture Mode to ‘Dynamic’, Contrast Enhancer to ‘High’, Color Tone to ‘Standard’ and have Brightness and Contrast at max. We hit 631 nits using those settings, although you may lose image accuracy.
This TV doesn't have local dimming. The video above is provided for reference only. If you want a similar TV with a full-array local dimming feature, check out the Sony X90J.

The Samsung Q70 has decent HDR brightness. It’s quite consistent across various scenes, and the overall brightness of scenes is as it should be, as you can see the EOTF follows the line closely. However, the brightest highlights may be lost.
We measured HDR brightness before calibration, using the ‘Movie HDR’ Picture Mode, with Brightness and Contrast set to max, Color Tone set to ‘Warm2’, and all additional picture processing settings disabled.
If you find HDR too dim, you can make it brighter by setting Contrast Enhancer to ‘High’ and ST.2084 to max. These settings result in this EOTF.
With Game Mode enabled, HDR peaks slightly brighter than with Game Mode disabled. The overall brightness of scenes is slightly below the target brightness, though. However, we didn’t notice a difference with actual content. Scenes with small highlights are dimmed because of the frame dimming.
Gray uniformity is okay, although this can vary between units. The edges and corners of the screen are noticeably darker, although it should be less noticeable with actual content. The uniformity is a bit better in near-dark scenes, but you may still notice some slight clouding or unevenness, depending on the content.
The Samsung Q70 has excellent black uniformity, but this may vary. There’s very little noticeable clouding throughout, and blooming around bright objects is fairly minimal. While it's quite uniform, the entire screen has more of a blue-ish hue in the photo.
The Samsung Q70 has narrow viewing angles, despite being advertised by Samsung as having a wide viewing angle. The image quickly starts to look washed out as you move off-center.
The Samsung Q70 has decent reflection handling. It does well with ambient light, but we don't recommend setting it directly opposite a window or light source because it's not as good at diffusing direct light.
The Samsung Q70 has excellent out-of-the-box accuracy. Most colors and white balance are quite accurate, but gamma doesn't really follow the target. Most scenes, and very bright scenes especially, are over brightened. The color temperature, however, is very close to the target.
After calibration, the accuracy is incredible. Remaining inaccuracies shouldn't be noticeable to the naked eye. Gamma and color temperature are almost perfect.

The Samsung Q70 uses a BGR subpixel layout. 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 that here.
The Samsung Q70 has a very good color gamut. It's wide enough for HDR content, with excellent coverage of the common DCI P3 color space and fair coverage of the wider Rec. 2020.
Color volume is okay. It handles dark, saturated colors pretty well thanks to its high contrast ratio, but it struggles with bright blues like most LED TVs.
The Samsung Q70 has decent gradient performance, although it's worse than the Samsung Q70/Q70T QLED. There's visible banding in the grays and greens, although it should be a little less noticeable in real content. If you notice banding, you can enable Noise Reduction to help smooth out gradients, though you may lose fine details in some scenes.
The Samsung Q70 shows no signs of temporary image retention, but this 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 TV has an impressive response time, though there's a bit of overshoot in the 0-20% transition, meaning there may be some smearing in dark scenes.
The Samsung Q70 uses Pulse-Width Modulation (PWM) to dim its backlight, which some people may be sensitive to. That said, in 'Movie' mode, it flickers at such a high frequency that it shouldn't be noticeable. In the 'Dynamic', 'Standard', 'Natural', and 'Filmmaker' Picture Modes, or with Picture Clarity or Game Mode enabled, the flicker drops down to 120Hz.
This TV has an optional Black Frame Insertion (BFI) feature, also known as backlight strobing, that can help reduce motion blur. To enable it to flicker the backlight at 60Hz, turn on LED Clear Motion in the Picture Clarity settings menu, or in the Game Motion Plus menu when Game Mode is enabled. For 120Hz, enable Picture Clarity settings but leave the Blur Reduction and Judder Reduction sliders at '0'. In Game Mode it always flickers at 120Hz, so no additional settings are needed. Note that the BFI score is based on how many frequencies the feature can flicker at, and not how well it performs.
The Samsung Q70 can interpolate motion up to 120 fps. This is also called the 'Soap Opera Effect'. It doesn't look particularly good on this TV, resulting in a lot of duplications and artifacts, especially during busy scenes. To enable it, set Picture Clarity to 'Custom' and set Blur Reduction to '10' for 60 fps content and higher or Judder Reduction to '10' for 30 fps content.
Due to the TV's quick response time, low frame rate content may appear to stutter because each frame is held on longer. If you notice stuttering, you can try enabling motion interpolation.
The TV removes 24p judder from any source without having to enable additional settings.
