![Samsung Q70C [Q70, Q70CD] QLED Picture](https://i.rtings.com/assets/products/iln4S8gG/samsung-q70c-q70-q70cd-qled/design-medium.jpg?format=auto)
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
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.

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.

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.

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.

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.

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.

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.
| Size | US Model | Short Model Code |
|---|---|---|
| 55" | QN55Q70CAFXZA | QN55Q70C |
| 65" | QN65Q70CAFXZA | QN65Q70C |
| 75" | QN75Q70CAFXZA | QN75Q70C |
| 85" | QN85Q70CAFXZA | QN85Q70C |
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 U8/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/X90CK for about the same price as the Samsung. Other TVs have better value overall unless you find the TV for a great price.
For more options, check out our recommendations for the best 4k TVs, the best 4k gaming TVs, and the best QLED TVs.
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.
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.
The TCL Q7/Q750G QLED is better than the Samsung Q70C QLED. The TCL has much better contrast due to its local dimming feature, so blacks are much deeper. The TCL has better HDR brightness, so highlights in HDR content pop more on it, and its better SDR brightness means it can overcome more glare in a bright room. The TCL also has a wider color gamut for more lifelike colors and a faster response time for less blur behind quick motion. On top of that, the TCL supports 4k @ 144Hz for PC gamers with high-end graphics cards.
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. 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.
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.
The Hisense U7K is better than the Samsung Q70C QLED. The Hisense has much better contrast due to its local dimming feature, so blacks are deeper on it. The Hisense also gets brighter in HDR, so highlights pop more when watching HDR content, and its wider color gamut and better color volume deliver more vibrant and lifelike colors. Finally, the Hisense has a quicker response time for less blur behind fast motion, and it's capable of 4k @ 144Hz for PC gamers with high-end graphics cards.
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.
The Samsung Q70C QLED is mostly better than the Sony X80K/X80CK. The Samsung has better contrast, so blacks are deeper on it, and it's the brighter TV, so it overcomes more glare in a bright room, and highlights stand out more in HDR content. The Samsung is also a better option for pairing with modern gaming consoles due to its HDMI 2.1 bandwidth, 4k @ 120Hz, and VRR support. However, the Sony has a wider viewing angle, which makes it the better option for watching TV as a group since the image doesn't degrade nearly as much from the sides.
The Samsung Q70C QLED is better than the Samsung CU8000. While the Q70C still lacks local dimming, it has a much deeper native contrast ratio than the CU8000, so watching content in a dark room is a better experience on the Q70C. It's also better for bright rooms due to its higher peak brightness in HDR and SDR. It's the better TV for gamers due to its faster response time alongside full 4k @ 120Hz support with VRR, while the CU8000 is limited to 4k @ 60Hz with no VRR. Surprisingly, the cheaper CU8000 has much better low-quality content smoothing, so content from streaming apps will look a bit better on it as it does a better job of clearing out compression artifacts.
The Samsung Q70C QLED is better than the Samsung CU7000/CU7000D. The Q70C gets brighter in HDR, supports a wider color gamut, and has better color volume, so colors are more vibrant and lifelike, and highlights pop a lot more than on the CU7000. The Q70C also gets much brighter in SDR, so it overcomes glare better in a bright room. The Q70C has better low-quality content smoothing, so cable TV and low-quality streams look better than on the CU7000. Finally, the Q70C is much better for gaming as it has HDMI 2.1 bandwidth, supports VRR, and has 4k @ 120Hz support.
The Samsung Q70C QLED is better than the LG QNED80 2022. 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.

The Samsung Q70C has a clean and simple look. The stand is center-mounted, so the TV fits well on smaller tables.
![Samsung Q70C [Q70, Q70CD] QLED Stand Picture](https://i.rtings.com/assets/products/LAjquoBf/samsung-q70c-q70-q70cd-qled/stand-large.jpg?format=auto)
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.
Footprint of the 65-inch stand: 13.6" x 11.5".
![Samsung Q70C [Q70, Q70CD] QLED Back Picture](https://i.rtings.com/assets/products/jBVhVDLz/samsung-q70c-q70-q70cd-qled/back-large.jpg?format=auto)
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.
![Samsung Q70C [Q70, Q70CD] QLED Borders Picture](https://i.rtings.com/assets/products/iKVzFM86/samsung-q70c-q70-q70cd-qled/borders-large.jpg?format=auto)

Overall, the Samsung Q70C has good build quality. The TV has an all-plastic build, but it still feels solid. The stand holds the TV well, and there's minimal wobbling when pushing or moving the TV. The back panel exhibits minimal flex, although there's more of it around the VESA holes or the inputs, but it isn't excessive and won't cause any issues.
![Samsung Q70C [Q70, Q70CD] QLED Contrast Picture](https://i.rtings.com/assets/products/K8zaSmHr/samsung-q70c-q70-q70cd-qled/contrast-large.jpg?format=auto)
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.
![Samsung Q70C [Q70, Q70CD] QLED Blooming Photo](https://i.rtings.com/assets/products/lFyYyUU1/samsung-q70c-q70-q70cd-qled/blooming-large.jpg?format=auto)
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.
This TV doesn't have a local dimming feature; as bright highlights don't move from zone to zone, there's no distracting flicker or brightness changes as they move across the screen.
![Samsung Q70C [Q70, Q70CD] QLED Blooming Photo In Game Mode](https://i.rtings.com/assets/products/r04nh4E0/samsung-q70c-q70-q70cd-qled/blooming-game-mode-large.jpg?format=auto)
Switching to Game Mode makes no noticeable difference in dark scene performance.

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
- HDR Tone Mapping: Static

The TV is slightly brighter overall in Game Mode, but it's not a noticeable difference, and it's still too low for a truly good HDR experience.
These measurements are after calibrating the HDR white point, with the following settings:
- HDR Picture Mode: Game
- Brightness: 50

![Samsung Q70C [Q70, Q70CD] QLED PQ EOTF Graph](https://i.rtings.com/assets/products/MjfnfkLf/samsung-q70c-q70-q70cd-qled/pqeotf-graph-small.jpg?format=auto)
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 very good SDR peak brightness. It's bright enough to overcome glare in a moderately-lit room, and there's minimal variation in brightness in most scenes.
These measurements are after calibration with the following settings:
- Picture Mode: Movie (Calibrated)
- Brightness: 50
- Color Tone: Warm2
![Samsung Q70C [Q70, Q70CD] QLED Color Gamut DCI-P3 Picture](https://i.rtings.com/assets/products/hA9aIY8m/samsung-q70c-q70-q70cd-qled/color-gamut-large.jpg?format=auto)

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.
![Samsung Q70C [Q70, Q70CD] QLED P3 Color Volume ITP Picture](https://i.rtings.com/assets/products/4XU66vdi/samsung-q70c-q70-q70cd-qled/volume-p3-itp-large.jpg?format=auto)

The TV has a decent color volume. However, it struggles with both dark saturated colors and very bright colors; in particular, the TV has a really hard time with greens, as they're not nearly as bright and saturated as they'd be on an ideal TV. Yellow and reds also deviate from the ideal, as they are undersaturated.
![Samsung Q70C [Q70, Q70CD] QLED Pre White Balance Picture](https://i.rtings.com/assets/products/lq9J0by6/samsung-q70c-q70-q70cd-qled/pre-white-balance-large.jpg?format=auto)

The Samsung Q70C has mediocre pre-calibration accuracy. Its color temperature is very cold, leading to an exaggerated blue tint in all scenes. Its white balance is also off, with dark grays being too red and brighter whites being too blue. Gamma doesn't follow our 2.2 target for moderately-lit rooms, and all scenes end up being darker than they should be, especially very dark scenes.
![Samsung Q70C [Q70, Q70CD] QLED Post White Balance Picture](https://i.rtings.com/assets/products/g33arPEU/samsung-q70c-q70-q70cd-qled/post-white-balance-large.jpg?format=auto)

The TV has satisfactory gray uniformity. There are some visible uniformity issues, with noticeable vignetting. There's some banding in parts of the screen and a bit of dirty screen effect. These uniformity issues are noticeable if you want to use the TV as a PC monitor or watch content with large areas of bright uniform color, like hockey. On darker colors, there's noticeable backlight bleeding, with the corners and sides of the image being blueish compared to the center.
![Samsung Q70C [Q70, Q70CD] QLED Native Black Uniformity Picture](https://i.rtings.com/assets/products/lt5rdzbP/samsung-q70c-q70-q70cd-qled/uniformity-large.jpg?format=auto)
The TV has good black uniformity. There's noticeable backlight bleeding, but the blooming around bright objects is minimal.

The Samsung 75Q70C has a sub-par viewing angle. The image shifts significantly when viewed at an angle, so this isn't a good TV for a wide seating arrangement or if you like to move around the TV while watching it.

The TV's reflection handling is decent. It does very well with glare from ambient lights, but it has a harder time with glare from lights or windows directly facing the TV.
![Samsung Q70C [Q70, Q70CD] QLED HDR Gradient Picture](https://i.rtings.com/assets/products/JxYqZAO2/samsung-q70c-q70-q70cd-qled/gradient-large.jpg?format=auto)
The Samsung Q70C has okay HDR gradient handling. There's noticeable, but not egregious, banding in every color gradient except light grays/whites and bright reds.
![Samsung Q70C [Q70, Q70CD] QLED Low-Quality Content Smoothing Picture](https://i.rtings.com/assets/products/7tBWD2PS/samsung-q70c-q70-q70cd-qled/lq-smoothing-large.jpg?format=auto)
The TV has mediocre low-quality content smoothing. There's significant macro-blocking in dark scenes when watching low-bitrate or low-quality content, and some fine details are lost.
![Samsung Q70C [Q70, Q70CD] QLED Sharpness Picture - 480p](https://i.rtings.com/assets/products/0m3MdwtL/samsung-q70c-q70-q70cd-qled/upscaling-sharpness-large.jpg?format=auto)
The TV has decent upscaling and sharpness processing. Fine details in low-resolution content are displayed well, but text is a bit blurry, and the scene looks a bit soft overall.
The optimal sharpness settings for low-resolution or low-bitrate content, with no over-sharpening, are as follows:
- Sharpness: 6
- Picture Clarity: Off
![Samsung Q70C [Q70, Q70CD] QLED Pixels Picture](https://i.rtings.com/assets/products/BpvcgtPm/samsung-q70c-q70-q70cd-qled/pixels-large.jpg?format=auto){kind=tracking}
The Samsung Q70C uses a BGR subpixel layout. This doesn't affect the image quality, but non-RGB subpixel layouts cause issues when used as PC monitors, as they reduce text clarity. There are workarounds, however, and you can read more about it here.
![Samsung Q70C [Q70, Q70CD] QLED Motion Blur Picture](https://i.rtings.com/assets/products/oBRmKgky/samsung-q70c-q70-q70cd-qled/motion-blur-large.jpg?format=auto)
![Samsung Q70C [Q70, Q70CD] QLED Response Time Chart](https://i.rtings.com/assets/products/1zn4EK43/samsung-q70c-q70-q70cd-qled/response-time-2-large.jpg?format=auto)
The TV has a good response time. There's still some blur around fast-moving objects, but this isn't annoying in practice. However, the TV is very slow, with transitions occurring in very dark scenes, resulting in black smearing.
![Samsung Q70C [Q70, Q70CD] QLED Backlight chart](https://i.rtings.com/assets/products/r5cFLeQs/samsung-q70c-q70-q70cd-qled/backlight-large.jpg?format=auto)
The Samsung Q70C uses pulse width modulation (PWM) to dim the backlight at all brightness levels. It flickers at 960Hz in the 'Movie' Picture Mode, which is fast enough that most people won't notice it. It does, however, drop down to 120Hz if any form of motion interpolation is enabled. The TV flickers at 120Hz in all other modes and at 60Hz with LED Clear Motion enabled in the 'Movie' or 'Game' Picture Modes.
![Samsung Q70C [Q70, Q70CD] QLED BFI Picture](https://i.rtings.com/assets/products/Ixm42CMt/samsung-q70c-q70-q70cd-qled/bfi-large.jpg?format=auto)
![Samsung Q70C [Q70, Q70CD] QLED BFI Frequency Picture](https://i.rtings.com/assets/products/fh9AJ4ob/samsung-q70c-q70-q70cd-qled/backlight-bfi-large.jpg?format=auto)
The TV has an optional backlight strobing feature, commonly known as black frame insertion. It can only flicker at 60Hz on this TV, which is slow enough to be noticeable. It's meant to reduce persistence blur, but it duplicates images and reduces the panel's brightness, so it's distracting to use.
![Samsung Q70C [Q70, Q70CD] QLED Motion Interpolation (30 fps) Picture](https://i.rtings.com/assets/products/VQvneIAx/samsung-q70c-q70-q70cd-qled/soap-opera-effect-30-fps-large.jpg?format=auto)
![Samsung Q70C [Q70, Q70CD] QLED Motion Interpolation (60 fps) Picture](https://i.rtings.com/assets/products/GGyrNvM3/samsung-q70c-q70-q70cd-qled/soap-opera-effect-large.jpg?format=auto)
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 removes 24p judder from any source, ensuring a smooth movie-watching experience. Picture Clarity must be set to 'Custom' with the sliders set to 0 to remove 24p judder from 60Hz sources.
The Samsung Q70C supports every variable refresh rate (VRR) technology, so you can get a nearly tear-free gaming experience no matter your gaming system.
The TV has superbly low input lag in Game Mode, ensuring a responsive gaming and desktop experience.
The TV supports all common resolutions up to 4k @ 120Hz. It also displays clear text with proper chroma 4:4:4, as long as you set the input to PC and have Input Signal Plus enabled on the HDMI port that your PC is connected to.

This TV can take full advantage of the PlayStation 5, with full 4k @ 120Hz and HDMI Forum VRR support. The Auto Low Latency Mode automatically switches the TV into Game Mode when you play a game from a compatible device.
![Samsung Q70C [Q70, Q70CD] QLED Xbox Series X Screenshot](https://i.rtings.com/assets/products/ebQR8idF/samsung-q70c-q70-q70cd-qled/xboxsx-large.jpg?format=auto)
This TV can take full advantage of the Xbox Series X or S, with full 4k @ 120Hz, HDMI Forum VRR, and FreeSync support. The Auto Low Latency Mode automatically switches the TV into Game Mode when you play a game from a compatible device.
The Samsung Q70C doesn't support Dolby Vision, but it does support Samsung's less widely used HDR10+ format. Otherwise, the TV has four HDMI 2.1 bandwidth ports, all capable of up to 4k @ 120Hz.
![Samsung Q70C [Q70, Q70CD] QLED Side Inputs Picture](https://i.rtings.com/assets/products/mbINq2Gf/samsung-q70c-q70-q70cd-qled/inputs-side-large.jpg?format=auto)

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.
![Samsung Q70C [Q70, Q70CD] QLED Frequency Response](https://i.rtings.com/assets/products/TVtajXNL/samsung-q70c-q70-q70cd-qled/frequency-response-graph-small.jpg?format=auto)
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.
![Samsung Q70C [Q70, Q70CD] QLED Total Harmonic Distortion](https://i.rtings.com/assets/products/HAHDeiqg/samsung-q70c-q70-q70cd-qled/total-harmonic-distortion-graph-small.jpg?format=auto)
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.
![Samsung Q70C [Q70, Q70CD] QLED Smart TV Picture](https://i.rtings.com/assets/products/5DUwfX3m/samsung-q70c-q70-q70cd-qled/smart-tv-large.jpg?format=auto)
The Samsung Q70C uses the 2023 version of Samsung's Tizen OS. It's a bit slow right after you turn on the TV, but it's smooth and fast afterward. Finding content is easy, and moving between apps and inputs is intuitive.
![Samsung Q70C [Q70, Q70CD] QLED Ads Picture](https://i.rtings.com/assets/products/rRIfTYhP/samsung-q70c-q70-q70cd-qled/ads-large.jpg?format=auto)
Like with most TVs, there are ads in the interface, and you can't fully disable them.
![Samsung Q70C [Q70, Q70CD] QLED Apps Picture](https://i.rtings.com/assets/products/k5In77TL/samsung-q70c-q70-q70cd-qled/apps-large.jpg?format=auto)
The Samsung app store has a ton of apps available, and you're sure to find any popular mainstream streaming app in the list of options.
![Samsung Q70C [Q70, Q70CD] QLED Remote Picture](https://i.rtings.com/assets/products/0QdpQItF/samsung-q70c-q70-q70cd-qled/remote-large.jpg?format=auto)
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.
