The Samsung Q70C QLED is the mid-range model in Samsung's 2023 QLED lineup and succeeds the Samsung Q70/Q70A QLED and Samsung Q70B QLED. The TV doesn't have local dimming to improve its contrast, but it's fully featured for gaming. It has up to 4k @ 120Hz support on all four of its HDMI 2.1 bandwidth ports and support for every variable refresh rate (VRR) technology for a nearly tear-free gaming experience from any VRR-enabled source. As for advanced format support, the TV supports advanced DTS and Dolby audio formats through ARC/eARC. While it doesn't support Dolby Vision HDR, it has Samsung's competing HDR10+ format. It uses Samsung's Neural Quantum Processor 4k for its image processing features. It comes with the 2023 version of Samsung's proprietary Tizen OS, and the TV has microphones in both the remote and the TV for hands-free voice control through the Alexa or Bixby voice assistants. It's available in four sizes: 55, 65, 75, and 85 inches.

Our Verdict

7.3 Mixed Usage

The Samsung Q70C is a decent TV overall, although it's best in situations where its fantastic input lag can be put to good use, like when gaming or when using the TV as a PC monitor. It's also not a great TV if you want to watch it with friends in a wide seating area, as its viewing angle is sub-par. Otherwise, its SDR brightness is very good, and its reflection handling is decent, so it can easily handle rooms with a few lights or windows when watching SDR content, like sports or TV shows. Its HDR brightness is adequate; good enough for dark rooms but not good enough to make HDR highlights pop in movies or games. Its response time is good, so fast-moving objects in sports, movies, or games have a little blur but nothing too noticeable.

Pros
  • Very good SDR peak brightness.
  • Decent reflection handling.
Cons
  • Sub-par viewing angle.
  • Doesn't have local dimming to improve its contrast.
7.0 TV Shows

The Samsung Q70C is decent for watching TV shows. It has very good brightness in SDR and decent reflection handling, so it can easily handle a few lights or windows in moderately-lit rooms. The TV has decent image processing, with decent low-resolution upscaling and acceptable low-quality content smoothing. So TV shows look satisfactory overall, whether from DVDs, cable, or streaming platforms. Unfortunately, the TV has a sub-par viewing angle, so this isn't a good choice for a wide seating arrangement, like if the entire family wants to watch shows together.

Pros
  • Very good SDR peak brightness.
  • Decent reflection handling.
  • Decent low-resolution upscaling.
Cons
  • Sub-par viewing angle.
7.2 Sports

The Samsung Q70C is decent for watching sports, but not with your friends in a wide seating area, as it has a sub-par viewing angle. It has very good brightness in SDR and decent reflection handling, so the TV can easily handle a few lights or some glare. It also has a good response time with most content, so there's a bit of blur behind fast-moving objects, like a ball or a puck zipping around the scene, but it's not annoying. Finally, the TV has decent gray uniformity. However, sports with uniform areas of bright color, like hockey, have noticeable uniformity issues, with regions of the image being visibly darker than others.

Pros
  • Good response time with most content.
  • Very good SDR peak brightness.
  • Decent reflection handling.
  • Decent low-resolution upscaling.
Cons
  • Sub-par viewing angle.
8.0 Video Games

The Samsung Q70C is good for gaming. The TV has many gaming-oriented features, like four HDMI 2.1 bandwidth ports, all supporting up to 4k @ 120Hz gaming, and support for every VRR technology for nearly tear-free gaming from any VRR-enabled source. Its input lag is fantastic, so inputs are fast and responsive. It also has a good response time with most content, with a little blur behind fast-moving objects but nothing too annoying. However, this isn't a good TV for fans of horror games or any other games that lean towards a dark color palette, as the TV's response time is significantly worse in dark scene transitions. The TV has good contrast, although games don't look vibrant overall without a local dimming feature. The TV gets bright in SDR and has decent reflection handling, so games look good in a moderately-lit room.

Pros
  • Good response time with most content.
  • Very good SDR peak brightness.
  • Extremely low input lag.
  • Has four HDMI 2.1 bandwidth ports with VRR.
  • Decent reflection handling.
  • Decent low-resolution upscaling.
Cons
  • Slow response time in dark scene transitions.
7.1 HDR Movies

The Samsung Q70C is a fair TV for movie lovers. It has adequate contrast, but unfortunately, it doesn't have a local dimming feature to make the TV's blacks deep and dark, so they look a bit blue in dark scenes. It has adequate HDR brightness, good enough for a pleasant viewing experience, but highlights don't pop. The TV has acceptable low-quality content smoothing, so low-bitrate content watched from streaming platforms looks fine overall but with noticeable macro-blocking in dark scenes. The TV's color accuracy is also mediocre pre-calibration; you don't need to calibrate it to look good, but it's helpful if you care about accuracy.

Pros
  • Automatically removes 24p judder from all sources.
Cons
  • Doesn't have local dimming to improve its contrast.
  • Mediocre color accuracy pre-calibration.
8.0 HDR Gaming

The Samsung Q70C is a good choice for gamers wanting to play the latest HDR games. It has four HDMI 2.1 bandwidth ports, all capable of up to 4k @ 120Hz, and supports every VRR technology for a nearly tear-free gaming experience from any VRR-enabled source. It has a good response time with most content, with a bit of blur around fast-moving objects but nothing too noticeable. However, the TV's response time is significantly worse in dark scene transitions, so it's not optimal for dark games, like titles in the horror genre. The TV's HDR brightness is adequate for a dark room, as games look bright enough for a pleasant HDR gaming experience, although highlights don't pop much.

Pros
  • Good response time with most content.
  • Extremely low input lag.
  • Has four HDMI 2.1 bandwidth ports with VRR.
Cons
  • Slow response time in dark scene transitions.
  • Doesn't have local dimming to improve its contrast.
  • Mediocre color accuracy pre-calibration.
8.1 PC Monitor

The Samsung Q70C is very good to use as a PC monitor. It has a good response time, so there's a little blur when moving windows around, but it's not annoying in practice. However, make sure not to set your operating system to 'dark' mode, as the TV's response time performs significantly worse in dark scene transitions, leading to black smearing. Otherwise, the TV's input lag is fantastic, so your mouse or controller inputs are super responsive. It displays chroma 4:4:4 signals properly, which is essential for clear text from a PC. It has good SDR brightness and decent reflection handling, so the TV easily handles moderately-lit offices. Unfortunately, the TV's viewing angle is sub-par, so the sides of the screen fade and look washed out if you're sitting too close.

Pros
  • Good response time with most content.
  • Very good SDR peak brightness.
  • Extremely low input lag.
  • Has four HDMI 2.1 bandwidth ports with VRR.
  • Decent reflection handling.
Cons
  • Slow response time in dark scene transitions.
  • Sub-par viewing angle.
  • Mediocre color accuracy pre-calibration.

Differences Between Sizes And Variants

We tested the 65-inch Samsung Q70C, and the results are valid for the 55, 75, and 85-inch models. The last four letters of the model code (in this case, FXZA) vary between regions and even retailers, and not all regions carry all the variants. As Samsung's European lineup differs, these results are only valid for the North American Q70C.

Our unit was manufactured in February 2023; you can see the label here.

Compared To Other TVs

The Samsung Q70C is a decent TV overall, more so for gamers, as it's a fully featured gaming TV with four HDMI 2.1 bandwidth ports. But as with other models in Samsung's QLED range, it comes up short compared to other products in the same market position or price range. There are superior models available from budget manufacturers, like the TCL Q7/Q750G QLED, but especially the much better Hisense U8H. The cheaper Sony X85K is also better than the Samsung Q70C overall, except for PC monitor usage, and you can even find the much better Sony X90K for about the same price as the Samsung. Other TVs have better value overall unless you find the TV for a great price.

Samsung Q80C [Q80, Q80CD] QLED
50" 55" 65" 75" 85" 98"

The Samsung Q80C QLED is a bit better than the Samsung Q70C QLED. The Q80C has a much wider viewing angle than the Q70C, great for watching with friends in a wide seating area. The Q80C also has local dimming to slightly improve its contrast, although its local dimming feature is mediocre. It gets a bit brighter than the Q70C in both SDR and HDR, has better color volume, and has a faster response time with much better dark scene transitions. Otherwise, they both have the same set of gaming features. The one edge that the Q70C has over its higher-tier sibling is its support for DTS audio formats, which is great if you like your movies on DVDs or Blu-rays as they tend to use DTS for their main audio track.

Samsung Q70/Q70A QLED
55" 65" 75" 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.

Samsung Q60C [Q60, Q60CD] QLED
32" 43" 50" 55" 65" 70" 75" 85"

The Samsung Q70C QLED is better than the Samsung Q60C QLED. The Q60C has slightly better contrast and vastly better black uniformity, but is worse in every other category. The Q70C is also a fully featured gaming TV, with four HDMI 2.1 bandwidth ports for up to 4k @ 120Hz gaming and support for every VRR technology, while the Q60C is limited to up to 4k @ 60Hz on its four HDMI 2.0 ports, and has no VRR support.

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

The Sony X85K is better than the Samsung Q70C QLED. The Sony is better than the Samsung TV in every category, except in its low-quality content smoothing capabilities, which are sub-par on the X85K. The Samsung is also better than the Sony if you want to use your TV as a PC monitor, as the Sony can't output chroma 4:4:4 properly with 4k @ 120Hz signals, although 4:4:4 works well with 4k @ 60Hz signals. The Sony also doesn't support 1440p @ 120Hz. Otherwise, it's better than the Samsung model in every other category and supports Dolby Vision HDR and ATSC 3.0, so it can stream over-the-air 4k channels.

LG QNED80 2023
50" 55" 65" 75" 86"

The Samsung Q70C QLED is better than the LG QNED80 2023. The Samsung has a higher native contrast ratio, so it looks better in dark rooms, with deeper blacks and better black uniformity. The Samsung also gets brighter, and HDR content looks better in general.

Stand

The stand feels a little cheap; it's made of plastic and feels hollow when you tap it. However, it's big and supports the TV very well; there's minimal wobble when you touch the TV. The stand lifts the TV about 3.15" above the table, so most soundbars fit in front of it without blocking the screen.

The back of the TV is plastic with fine horizontal etchings, and it feels solid overall, without excessive flex around the VESA holes or inputs. There are grooves on the back of the TV and the stand for cable management. The inputs are recessed in an inlet on the side of the TV, and they're hard to reach if the TV is wall-mounted.

The Samsung Q70C has a very good native contrast ratio, but there's no local dimming to improve it further. This means that blacks look good in a dark room but look a bit blue when bright highlights are on the screen, as the TV can't emphasize bright highlights without impacting dark areas.

As this TV doesn't have a local dimming feature, there's no blooming around bright objects in dark scenes. The entire backlight is always on at the same intensity, so blacks look blue when bright highlights are present.

The Samsung Q70C has adequate HDR brightness. It doesn't vary from scene to scene, but as the TV lacks a local dimming feature, highlights don't stand out against the rest of the image.

These measurements are after calibrating the HDR white point, with the following settings:

  • Picture Mode: FILMMAKER Mode
  • Brightness 50
  • Contrast: 50
  • Color Tone: Warm 2

The PQ EOTF tracking is excellent on this TV. Dark scenes and midtones are displayed close to the content creator's intent. Near-blacks are raised, however, but this is typical of LED TVs. Besides that, the TV tracks the content creator's intent very well. There's a sharp cutoff near the TV's peak brightness, though, which causes a loss of fine details in bright highlights.

The Samsung Q70CD has a good color gamut. It has excellent coverage of the common DCI-P3 color space, which is used in most HDR content. Unfortunately, most of its color range is undersaturated, even more so in greens and yellows. Its coverage of the less widely used Rec. 2020 color space is passable, but it's even more undersaturated here than in the DCI-P3 space.

This TV has an optional motion interpolation feature to improve the appearance of motion. It can increase the frame rate of content up to 120fps. Unfortunately, it doesn't work well on this TV, resulting in image duplications and artifacts, especially during fast action scenes.

The TV's performance regarding stutter is decent; there's visible stutter with low-frame rate content, like when watching movies, but 60fps content looks fantastic.

The TV supports advanced Dolby and DTS audio passthrough, which is great if you like to watch movies on DVD or Blu-ray as they tend to use DTS formats for their main audio tracks. DTS 5.1 is only available with ARC/eARC, as it doesn't work with an optical connection.

The TV has a mediocre frequency response. It has barely any bass, and its sound reproduction becomes less accurate as you raise the volume. There's also a fair amount of compression artifacts, so it doesn't sound good at max volume. The TV's midtones sound good at a moderate listening volume, so dialogue is easy to understand.

The TV's distortion performance is middling. At or near max volume, the TV's speakers significantly distort the sound. It's better at moderate volumes but still not great. Distortion depends on the content, and not everyone is sensitive to it.

The Samsung Q70C uses the 2023 version of Samsung's remote control. There are buttons dedicated to specific streaming apps, which vary by region. It also has an integrated microphone for voice commands, and the TV comes with Bixby and Amazon's Alexa voice assistants. Aside from the mic in the remote, the TV itself has an integrated microphone for hands-free voice control. Voice commands work well; you can change the input, ask to open specific apps, ask for time or the weather, or even tell the TV to change the intensity of its backlight. The remote has a rechargeable battery, which you can charge through USB-C or with solar energy.
