This TV was replaced by the Samsung Q70C [Q70, Q70CD] QLED

The Samsung Q70/Q70A QLED is the mid-range model in Samsung’s 2021 4k QLED lineup, sitting between the Samsung Q60/Q60A QLED and the Samsung Q80/Q80A QLED. It competes with other mid-range models like the Sony X85J, the LG NANO90 2021, and the Hisense U7G. It has features that are usually included with higher-end models, like its HDMI 2.1 bandwidth, 120Hz panel, and variable refresh rate (VRR) support. However, it also lacks some important features like local dimming, and in Samsung's case, the 'Ultra Viewing Angle' technology. Still, it's a well-rounded TV that comes with the easy-to-use Tizen OS as its smart platform.

Our Verdict

7.5 Mixed Usage

The Samsung Q7 Series is a great TV for most uses. Thanks to its high contrast ratio, it looks excellent in a dark room, with deep blacks and no distracting blooming around bright highlights. It's also good for watching shows and sports in 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 responsive when gaming or using it as a PC monitor. HDR looks good, but it doesn't get bright enough to bring out the brightest highlights, and it lacks a local dimming feature to improve the contrast.

Pros
  • Very good contrast.
  • Bright enough to overcome glare.
  • Impressive response time delivers smooth motion.
Cons
  • No local dimming.
  • Image fades and looks washed out as you move off-center.
6.9 TV Shows

The Samsung Q70A is good for watching TV shows in a bright room. Although it has only decent reflection handling, it gets bright enough to overcome moderate amounts of glare in a bright room, so visibility isn't an issue. It upscales cable TV channels and older shows on DVD well, and the built-in Tizen OS has a great selection of streaming apps, so you can quickly find your favorite shows. Unfortunately, it has a narrow viewing angle, so it's not ideal for a wide seating arrangement or if you like to move around with the TV on, as the image fades and looks washed out at an angle.

Pros
  • Bright enough to overcome glare.
  • Apps and interface run smoothly.
Cons
  • Image fades and looks washed out as you move off-center.
7.2 Sports

The Samsung Q70A is good for watching sports in a bright room. It has an impressive response time, so motion looks smooth with fast-moving balls or players. It gets bright enough to overcome glare in most rooms, and it also has decent reflection handling, so glare isn't an issue overall. That said, it has a narrow viewing angle, so it's not ideal if you want to watch the game with a big group, as the image fades and looks washed out at an angle. It also has uniformity issues with some distracting dirty screen effect in the center.

Pros
  • Bright enough to overcome glare.
  • Impressive response time delivers smooth motion.
Cons
  • Image fades and looks washed out as you move off-center.
8.3 Video Games

The Samsung Q70A is an excellent TV for playing video games. Its impressive response time delivers a clear image with minimal motion blur or ghosting behind fast-moving objects, and it has an incredibly low input lag. It supports FreeSync variable refresh rate (VRR) technology to reduce screen tearing. Also, it supports 4k @ 120Hz games without issues, but only on one port, which is disappointing if you have more than one new-gen console.

Pros
  • Supports FreeSync VRR.
  • Impressive response time delivers smooth motion.
  • Low input lag.
Cons
  • No local dimming.
  • HDMI 2.1 bandwidth on only one port.
7.5 HDR Movies

The Samsung Q70A TV is great for watching movies in HDR. It's helped by its high contrast ratio, delivering deep blacks and bright highlights with no blooming, but it lacks a local dimming feature to improve the dynamic range. It displays a wide color gamut for HDR, so HDR content is vivid and realistic, but its HDR brightness is a bit limited, so the brightest highlights don't quite pop as well as they should.

Pros
  • Very good contrast.
  • Removes 24p judder from all sources.
  • Displays wide color gamut.
Cons
  • No local dimming.
  • Stutter with low frame rate content.
  • Not quite bright enough to make highlights pop.
8.1 HDR Gaming

The Samsung Q7DA is great for HDR gaming. The fast response time, low input lag, and variable refresh rate support deliver a smooth and a responsive gaming experience, with minimal tearing. However, its HDR brightness in Game Mode is only okay, so the brightest highlights don't pop as they should. On the upside, it supports all common resolutions for advanced consoles, including 4k @ 120Hz, but only on one port, so you can only take full advantage of one new-gen console.

Pros
  • Very good contrast.
  • Supports FreeSync VRR.
  • Impressive response time delivers smooth motion.
  • Low input lag.
Cons
  • No local dimming.
  • HDMI 2.1 bandwidth on only one port.
  • Not quite bright enough to make highlights pop.
8.4 PC Monitor

The Samsung Q7DA is great for use as a PC monitor. It displays chroma 4:4:4 properly, which is important for text clarity while using it as a PC monitor. It also has incredibly low input lag, ensuring your mouse movements are smooth and games feel responsive. However, it has a narrow viewing angle, so the edges of the screen look washed out if you're sitting up close or if you need to use it in a meeting room with a wide seating area.

Pros
  • Displays chroma 4:4:4 properly for clear text.
  • Supports FreeSync VRR.
  • Low input lag.
Cons
  • Image fades and looks washed out as you move off-center.
  • HDMI 2.1 bandwidth on only one port.
  • 7.5 Mixed Usage
  • 6.9 TV Shows
  • 7.2 Sports
  • 8.3 Video Games
  • 7.5 HDR Movies
  • 8.1 HDR Gaming
  • 8.4 PC Monitor

Differences Between Sizes And Variants

We bought and tested the 55-inch Samsung Q70A, and these results are also valid for the 65, 75, and 85-inch sizes. There's a variant sold at Costco and Sam's Club as the Samsung Q7 Series or the Samsung Q7DA.

Size US Model Short Model Code Panel Type
55" QN55Q70AAFXZA QN55Q70A VA
65" QN65Q70AAFXZA QN65Q70A VA
75" QN75Q70AAFXZA QN75Q70A VA
85" QN85Q70AAFXZA QN85Q70A VA

The unit was manufactured in February 2021. You can see the label here.

Compared To Other TVs

The Samsung Q70A is a good mid-range 4k TV. While it lacks certain features that you get with higher-end models, like full-array backlighting and local dimming, it has an exceptionally high contrast ratio. It comes with many advanced features like eARC, HDMI 2.1 bandwidth, and VRR support. It's a bit better overall than its 2023 version, the Samsung Q70C QLED, so don't worry about upgrading if you already own the Q70A.

For more options, check out our recommendations for the best 4k TVs, the best 4k gaming TVs, and the best QLEDs.

Samsung Q70C [Q70, Q70CD] QLED
55" 55" 65" 65" 75" 75" 85" 85"

The Samsung Q70/Q70A QLED and Samsung Q70C QLED are extremely similar TVs, although the Q70A has a small edge in most categories. The older model has better image quality, with better contrast, is slightly brighter in both HDR and SDR, is significantly more accurate pre-calibration, and has better black uniformity. However, the Q70C does have better image processing, with better low-quality content smoothing and better upscaling capabilities. It also supports DTS audio formats, which is great for DVDs and Blu-rays as they tend to use DTS as their main audio track. Finally, it has four HDMI 2.1 bandwidth ports versus only one for the Q70A, which is great if you have multiple HDMI 2.1 devices.

Sony X85J
43" 50" 55" 65" 75" 85"

The Samsung Q70/Q70A QLED and the Sony X85J are nearly identical. The Sony that we tested has better gray uniformity, but this can vary between units. The Samsung is a bit better for gaming, as it has lower input lag for a more responsive gaming experience, and it has FreeSync support. However, the Sony is G-SYNC compatible, which is good if you have a NVIDIA graphics card.

Samsung Q80/Q80B QLED
50" 55" 65" 75" 85"

The Samsung Q70/Q70A QLED and the Samsung Q80/Q80B QLED are both good TVs with different strengths and weaknesses. Although the Q70A doesn't have a local dimming feature like the Q80B, it's still better for dark rooms because it displays deep blacks and has less blooming around bright objects. However, the Q80B gets brighter, especially in HDR, and it's a better choice for wide seating arrangements because it has a wider viewing angle. They each have HDMI 2.1 bandwidth, but the Q80B has it on all four inputs, while it's just limited to one input on the Q70A.

Samsung Q60/Q60B QLED
43" 50" 55" 60" 65" 70" 75" 85"

The Samsung Q70/Q70A QLED is better overall than the Samsung Q60/Q60B QLED. The Q70A has more gaming features like HDMI 2.1 bandwidth, a 120Hz panel, and VRR support, all of which the Q60B doesn't have. Also, the Q70A has a much better response time for better motion handling. The Q70A also gets brighter in SDR, so it's better for well-lit rooms.

Sony X85K
43" 50" 55" 65" 75" 85"

The Samsung Q70/Q70A QLED and the Sony X85K are both good TVs with similar features. There isn't much difference between them, so choosing one over the other comes down to personal preference. The Q70A gets a bit brighter and has better contrast, so the overall picture quality is slightly brighter, but it isn't a significant difference. If you watch content in Dolby Vision, the Sony TV supports it, which the Samsung model doesn't.

Samsung Q80/Q80A QLED
55" 65" 75" 85"

The Samsung Q80/Q80A QLED and the Samsung Q70/Q70A QLED are good TVs with different panel types. The Q80A has an ADS panel, which has much wider viewing angles. It also gets significantly brighter in HDR, so highlights stand out the way they should. However, the Q70A has a VA panel with a much better contrast ratio and improved black uniformity. Even though the Q80A has a full-array local dimming feature, which the Q70A doesn't have, the Q70A is better for dark room viewing due to its higher contrast.

Samsung Q60/Q60A QLED
32" 43" 50" 55" 60" 65" 70" 75" 85"

The Samsung Q70/Q70A QLED is better overall than the Samsung Q60/Q60A QLED. The Q70A offers better performance and more features. While they're both VA panels, the Q70A has a higher contrast ratio and similar viewing angles. It also has a faster response time, a 120Hz panel, and extra gaming features like VRR and ALLM, as well as an HDMI 2.1 port for advanced consoles. Meanwhile, the Q60A is limited to 60Hz and lacks most extra features. However, it's available in smaller sizes than the Q70A.

Samsung Q70/Q70T QLED
55" 65" 75" 82" 85"

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. 

Samsung Q80/Q80T QLED
49" 50" 55" 65" 75" 85"

The Samsung Q80/Q80T QLED is a bit better overall than the Samsung Q70/Q70A QLED. While it has a lower contrast ratio as a result of its 'Ultra Viewing Angle' layer, it also has a local dimming feature to improve black levels, while the Q70A doesn't. Unfortunately, the Q80T suffers a bit when in 'Game Mode', as the local dimming and HDR brightness perform worse. Still, it has a slightly quicker response time, so motion looks clear. It also delivers a better HDR experience overall since it gets brighter than the Q70A in HDR.

LG C1 OLED
48" 55" 65" 77" 83"

The LG C1 OLED is much better overall than the Samsung Q70/Q70A QLED. The LG has an OLED panel with a much higher contrast ratio for deeper blacks, and it also has wider viewing angles and a quicker response time. However, the LED panel on the Samsung gets brighter in SDR, making it a better choice for well-lit rooms, and it won't burn in like an OLED.

Samsung QN85A QLED
55" 65" 75" 85"

The Samsung QN85A QLED is better overall than the Samsung Q70/Q70A QLED, but they have different panel types with advantages and disadvantages. It has an IPS-like panel with wide viewing angles, and the Q70A has a VA panel with better native contrast. However, the QN85A has a local dimming feature, which the Q70A doesn't have, to improve the picture quality in dark scenes. The QN85A also has better reflection handling, and it gets brighter, especially in HDR, making it the better choice for watching HDR content.

Hisense U7G
55" 65" 75"

The Hisense U7G is much better than the Samsung Q70/Q70A QLED. The Hisense has a full array local dimming system, it's brighter, and it's a bit more versatile, with two HDMI 2.1 ports instead of just one on the Samsung. The Hisense also has a composite input, great if you have an older video game console. Despite these advantages, some people might prefer the Samsung, as it has better black uniformity, better contrast, and it's more accurate out of the box.

Sony X90J
50" 55" 65" 75"

The Sony X90J and the Samsung Q70/Q70A QLED are very similar. The main differences are that the Samsung doesn't have local dimming and doesn't get as bright in HDR. Its gradient handling isn't as good as the Sony's, which means you might see more banding in some content. However, if you plan on gaming, the Samsung is a better choice because it has lower input lag and supports FreeSync VRR. Also, the Sony can't display a 1440p @ 120Hz signal on the Xbox Series X or a 4k @ 120Hz signal in Dolby Vision.

LG NANO85 2021
50" 55" 65" 75" 86"

The Samsung Q70/Q70A QLED is better than the LG NANO85 2021. The Samsung has a higher contrast ratio, resulting in deeper blacks in a dark room. Although they each have decent reflection handling, the Samsung is also much better for bright rooms because it gets brighter and can better overcome glare. Finally, the Samsung TV has a slightly quicker response time and lower input lag for a better gaming experience.

LG NANO90 2021
55" 65" 75" 86"

The Samsung Q70/Q70A QLED and the LG NANO90 2021 are both good TVs that use different panel types. The Samsung has a VA panel with a much better contrast ratio, and even though it doesn't have local dimming like the LG, it's still a better choice for use in dark rooms. The LG doesn't get as bright as the Samsung, but it has much better reflection handling. The LG has an IPS panel with wide viewing angles, so it's a better choice for wide seating arrangements. They're both very good for gaming as they each have a 120Hz panel and VRR support, but the LG is G-SYNC compatible, which the Samsung isn't.

TCL R745 QLED
85"

The TCL R745 QLED is better overall than the Samsung Q70/Q70A QLED. The TCL gets much brighter, making highlights pop in HDR, and it does a better job at fighting glare. The TCL has a local dimming feature, which the Samsung doesn't, but the local dimming makes the picture quality worse because there's a ton of blooming. The Samsung has more gaming features because it has lower input lag and an HDMI 2.1 input, which the TCL doesn't have, meaning that you can play 4k games up to 120fps on the Samsung.

Sony X900H
55" 65" 75" 85"

The Sony X900H and the Samsung Q70/Q70A QLED both perform well, although the Sony delivers better picture quality. While the Samsung has a higher native contrast ratio, the Sony's is still high, and it has a full-array local dimming feature to improve black levels. The Samsung has a lower input lag and comes with FreeSync support.

Samsung The Frame 2021
43" 50" 55" 65" 75" 85"

The Samsung The Frame 2021 and the Samsung Q70/Q70A QLED perform very similarly overall. The Q70A edges out the Frame slightly because it has a better contrast ratio and higher peak brightness. That said, the Frame might be a better choice if you want a clean setup because it has the One Connect Box, and it comes with a no-gap wall mount.

Sony X91J
85"

The Sony X91J is better overall than the Samsung Q70/Q70A QLED because it has more features. The Sony is only available in an 85 inch size, and the Samsung is available in 55 to 85 inch size models. The Sony delivers a better experience for watching movies because it has a local dimming feature, which the Samsung doesn't have, but the Samsung gets brighter if you want to use it in a well-lit room.

LG GX OLED
55" 65" 77"

The LG GX OLED is better than the Samsung Q70/Q70A QLED, but they're very different TVs. The LG is a high-end OLED, while the Samsung is a lower mid-range LED TV. The Samsung uses a VA panel, so it has a fantastic contrast ratio, but it still doesn't quite compare with the near-infinite contrast of the LG. The LG also has wider viewing angles, a faster response time, and feels more premium, but the Samsung doesn't have any risk of burn-in.

The stand looks a little cheap, but it supports the TV well for the most part. It's center-mounted, so you can place it on a smaller table. The stand lifts the TV about 3.07 inches above the table, so most soundbars fit in front of it without blocking the screen.

The Samsung Q70A has good build quality. It feels well-built overall, despite some wobble due to the thin profile and narrow stand. The stand feels somewhat cheap, but it has a plastic cover that slides in to cover the two feet. Sadly, the bezels don't feel like they're flush around the screen, and there's a small gap.

The PQ EOTF tracking is decent. Content mastered at 4,000 nits is displayed almost perfectly. Content mastered below is over-brightened considerably, and all content is raised a bit in near-blacks. There's also a very sharp cutoff as the TV approaches its peak brightness, causing a loss of fine details in very bright scenes.

The Samsung Q70A QLED has excellent peak brightness. It gets very bright, and even though you won't get the same peak brightness as with Mini LED TVs like the Samsung QN90A QLED, it’s able to overcome glare even in a bright room. There's also no noticeable variation in brightness with different scenes.

These measurements are after calibration with the following settings:

  • Picture Mode: Movie
  • Brightness: Max
  • Color Temperature: Warm 2

The Samsung Q70A 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. While its DCI P3 coverage is good enough for the large majority of HDR movies that use this color space, the Rec. 2020 coverage is more limited.

The Samsung Q70A has excellent accuracy in SDR before calibration. Most colors and white balance are accurate, and the color temperature is very close to the target. However, gamma doesn't follow the 2.2 target at all, and almost all scenes are brighter than they should be for a moderately-lit room.

The gray uniformity is just okay. The edges and corners of the screen are noticeably darker, and there's some dirty screen effect in the center. This is noticeable if you want to use the TV as a PC monitor or you watch sports with large areas of bright colors, like hockey or basketball. The uniformity is a bit better in near-dark scenes, but there's still some slight clouding or unevenness.

The Samsung Q70A has a narrow viewing angle, despite being advertised by Samsung as having a wide viewing angle. The image quickly starts to look washed out as you move off-center, and it's not ideal for wide seating arrangements. If you want a TV with a wide viewing angle, then check out the LG NANO85 2021.

Like most TVs on the market, this TV uses a BGR (Blue-Green-Red) subpixel layout instead of the traditional Red-Green-Blue layout. For video content, it doesn't cause any issues, but if you're planning on using this TV as a PC monitor, this reduces text clarity a bit, although there are easy workarounds for it. You can read more about that here.

The TV has an impressive response time, so motion looks smooth and there's relatively little blur or ghosting behind fast-moving objects. However, like other VA panel TVs, it has a slow response time with dark transitions, which results in black smearing. It's noticeable with fast-moving content in dark scenes.

PWM Dimming Frequency
960 Hz

This TV uses Pulse Width Modulation (PWM) to dim its backlight. In 'Movie' mode, it flickers at such a high frequency that most people won't notice it. In the 'Dynamic', 'Standard', 'Natural', and 'Filmmaker' Picture Modes, or with Picture Clarity enabled, the flicker drops down to 120Hz, which creates image duplication.

The flicker is inconsistent in Game Mode, and the flicker is noticeable with the Xbox Series X with VRR enabled, because it's flickering between 60-120Hz with the backlight at any setting, and this can become distracting. However, with VRR disabled on the Xbox, the flicker disappears. With a laptop with an RTX 3060 graphics card, it flickers at 960Hz with G-SYNC enabled and at 120Hz with G-SYNC disabled. Also, on a PC with a Radeon 6600 XT graphics card in Game Mode, it flickers at 480Hz with VRR both on and off.

This TV has an optional backlight strobing feature, also known as black frame insertion, that can help reduce persistence blur. It can flicker at 60Hz or 120Hz, depending on which setting you're using, both in and out of Game Mode. It looks good overall, but there's a bit of image duplication.

The Samsung Q7 Series supports FreeSync variable refresh rate technology, which is automatically enabled in Game Mode to reduce screen tearing. It's not officially supported by NVIDIA to be G-SYNC compatible, but G-SYNC compatibility works without any screen tearing throughout the entire refresh rate range. However, at times with G-SYNC enabled 4k @ 120Hz signals flash a black screen and randomly stop working until you reset the TV.

The TV has a poor frequency response. It's worse than other Samsung models, including the Samsung Q70/Q70T QLED. The bass is especially bad, and it doesn't get very loud. There's barely a difference in volume between 60 and 100. There's a room correction feature called Adaptive Sound+, and there wasn't a significant difference in the frequency response with it enabled or disabled.
