The Samsung QN85C/QN85CD QLED is the Samsung QN85B QLED's successor and is Samsung's lowest Neo QLED offering in 2023, sitting below the Samsung QN90C/QN90CD QLED and the Samsung QN95C QLED. It features a Mini LED backlight, allowing for high levels of brightness and fine control over the TV's local dimming zones. It uses Samsung's 2023 Tizen OS smart interface, which offers many apps. It also has an integrated microphone on both the TV and the remote, allowing for hands-free voice control through Bixby or Amazon's Alexa. It's a fully featured gaming TV with 4 HDMI 2.1 bandwidth ports for up to 4k @ 120Hz gaming and support for every variable refresh rate (VRR) technology. It comes in 55, 65, 75, and 85-inch sizes.
Our Verdict
The Samsung QN85C is a very good TV overall. Its contrast is exceptional, especially with local dimming set to 'High', so movies look amazing in a dark room. It has decent reflection handling for bright rooms, and the TV gets bright in both SDR and HDR, so TV shows and sports look great even when there are a ton of lights around. Its primary weakness is its mediocre low-quality content smoothing, negatively affecting the image quality of TV shows and movies from streaming services. Aside from that, the TV has plenty of strengths: exceptionally low input lag for very responsive inputs when gaming or using a PC mouse, a ton of gaming features, and a good response time for clear motion whenever fast-moving objects are on screen. As a whole, the TV is solid.

The Samsung QN85C is a very good TV for watching sports. Its SDR peak brightness is exceptional, and this model has decent reflection handling, so the TV looks amazing in very bright rooms. The TV has a good response time, so fast-moving objects like a puck or a player are clear and easy to make out. The TV has good gray uniformity, so while there is some banding and vignetting on it, it's not bad enough to be annoying while watching sports with large sections of bright color. Finally, the TV has a very good viewing angle, so your friends have a consistent viewing experience even when sitting at various angles from the TV.

The Samsung QN85C is a very good TV for watching the latest HDR movies. It has a great contrast ratio, especially with local dimming set to 'High'. This means that HDR movies pop when watched in a dark room; blacks don't look gray, and highlights are bright and vibrant next to very deep blacks. Plus, the TV has excellent HDR peak brightness, so highlights look amazing in a dark room, and HDR movies on this TV can even wow in a bright room. Unfortunately, it has mediocre low-quality content smoothing, so movies from streaming services have some noticeable macro-blocking in dark scenes, as well as a loss of detail due to the smoothing process.

The Samsung QN85C QLED is amazing for HDR games. Its HDR brightness in Game Mode is just as good as outside of it, and its contrast and dark details look great in Game Mode. It does come at the expense of a bit more blooming, however. The TV has four HDMI 2.1 bandwidth ports with up to 4k @ 120Hz support, which is great if you own multiple consoles and a PC as you can connect them all, and it supports every VRR technology for a nearly tear-free gaming experience. Finally, the TV has a good response time, ensuring motion is clear even when the action gets fast and furious.

The Samsung QN85C is amazing when used as a PC monitor. Its reflection handling is decent, but the TV makes up for it in a big way with exceptional brightness in SDR and amazing brightness in HDR, so it can handle any bright office. It has an RGB subpixel layout, so there are no issues with text clarity. Its viewing angle is very good; not the best, but there's minimal color shifting when sitting close to it, except if you were to sit very close to a bigger-sized panel. It supports up to 4k @ 120Hz on all of its HDMI ports, and it supports every VRR technology, so it's a great choice for some PC gaming. It also has an incredibly low input lag and a good response time; your inputs are fast and responsive on this TV, and there's little blur behind fast-moving objects, like when you're quickly dragging windows around on a contrasting background.

Differences Between Sizes And Variants
We tested the 65-inch Samsung QN85C (QN55QN85CAFXZA), but it's also available in 55, 75, and 85-inch sizes. Note that with Samsung TVs, the six letters after the short model code (CAFXZA in this case) vary between specific retailers and regions. There's also a QN88C variant sold in some UK retailers; differences with the QN85C are cosmetic. European versions of this TV are equipped with a VA panel and perform differently than the North American model we reviewed. VA panels have better native contrast but a worse viewing angle.
| Size | US Model | Short Model Code | Panel type (US) | Panel type (Europe) | Dimming zones* |
|---|---|---|---|---|---|
| 55" | QN55QN85CAFXZA | QN55QN85 | ADS | VA | 504 |
| 65" | QN65QN85CAFXZA | QN65QN85 | ADS | VA | 720 |

Compared To Other TVs
The Samsung QN85C is a great TV with a truly amazing local dimming feature, giving it an amazing contrast and truly exceptional black uniformity. Overall, it's an excellent TV and is almost as good as the more expensive Samsung QN90C/QN90CD QLED, so it's the better value for most people. It's also leagues ahead of the models below it, like the Samsung Q80C QLED. It's very similar to its predecessors, the Samsung QN85A QLED and Samsung QN85B QLED, so don't bother upgrading if you own one. It's also very similar to its successor, the Samsung QN85D/QN85DD QLED, although the QN85D uses a VA panel, giving it better contrast but with a far worse viewing angle. Still, if you already own the QN85C, it's not worth the upgrade. Unfortunately, the QN85C is outpaced by the top-tier models from budget brands. The Hisense U8/U8H, in particular, is a much better deal for a superior level of performance.
For more options, check out our recommendations for the best TVs, the best QLED TVs, and the best 4k gaming TVs.
The Samsung QN85D/QN85DD QLED and Samsung QN85C/QN85CD QLED are almost identical, with a few notable exceptions. The newer QN85D has a VA panel, giving it better contrast than the QN85C at the cost of a significantly worse viewing angle. Thus, the QN85D is better as a home entertainment option as movies look extremely punchy when watched in a dark room, while the QN85C is better for large viewing parties as its image doesn't degrade nearly as much when viewed from the sides.
The Samsung QN90C/QN90CD QLED is better than the Samsung QN85C/QN85CD QLED, but not by as much as you'd think. The QN90C gets much brighter than the QN85C in both SDR and HDR, but in practice, this isn't always noticeable, as most content isn't mastered to take advantage of such high brightness levels. The QN90C's Automatic Brightness Limiter (ABL) also more aggressively dims the scene when it gets extremely bright, to a point where the two TVs are equally as bright in the brightest of scenes. However, the QN90C has better color volume and reflection handling than the QN85C.
The Samsung QN85C/QN85CD QLED and the Sony X90L/X90CL are similar TVs, each with strengths. The Samsung has a wider viewing angle, so it's better suited for watching TV with friends. The Samsung is also slightly better for gamers due to its lower input lag and HDMI 2.1 bandwidth on all four ports. On the other hand, the Sony has a faster response time, so there is less blur behind quick motion. The Sony also has better processing, so low-resolution and low-quality content looks better.
The Samsung QN85C/QN85CD QLED is better than the Samsung Q80C QLED. It has a much better contrast, helped by a much better local dimming feature. It gets much brighter in SDR and HDR, has better color volume, is the more accurate TV, has vastly superior black uniformity, and looks much better before being calibrated.
The LG C3 OLED is much better than the Samsung QN85C/QN85CD QLED. The Samsung is slightly but noticeably brighter than the LG, but the OLED has vastly superior reflection handling, so they look about equally as good in bright rooms. In dark rooms, however, the LG looks much better than the Samsung due to its nearly infinite contrast ratio. Plus, the LG is the more accurate of the two TVs and has slightly better image processing, a wider viewing angle, Dolby Vision, and advanced DTS audio format support. It's also better for gaming due to its nearly instantaneous response time.
The Samsung QN85B QLED and Samsung QN85C QLED are extremely similar TVs. The QN85C is the more accurate TV with a wider color volume, so it looks more vibrant than its predecessor. Inversely, the QN85B's local dimming zone transitions are a bit better than its successor except in Game Mode, where its zone transitions are noticeably worse than in other modes.
The Samsung S90C OLED is much better than the Samsung QN85C/QN85CD QLED. The QN85C has one advantage over the S90C: it can get noticeably brighter in SDR than the OLED. However, the Samsung TV compensates by having far superior reflection handling, so overall, they're about equally good in bright rooms when watching SDR content. Otherwise, the S90C is the superior TV in every other facet: much better contrast, a wider color gamut, a much wider viewing angle, four full 4k @ 144Hz ports versus 4k @ 120Hz on the QN85C, and a nearly instantaneous response time.
The Samsung QN90B QLED is better than the Samsung QN85C QLED. The QN90B gets much brighter than the QN85C, but in practice, this isn't always noticeable as most content just isn't mastered to take advantage of such high brightness levels. The QN85C is the more accurate TV of the two; it respects the content creator's intent well. However, the QN90B is the more colorful TV, with a wider color gamut and better color volume, and it has much better reflection handling, although it does have some rainbow smearing.
The Samsung QN85C/QN85CD QLED is better than the TCL Q7/Q750G QLED. The TCL has better contrast and black uniformity than the Samsung, but the Samsung gets brighter in both HDR and SDR, so it's better for bright rooms and pops a bit more due to its better color volume. The Samsung TV also has better overall processing, although the TCL does a better job smoothing out macro-blocking with low-quality content. The Samsung is also the more accurate TV of the two, has a much better viewing angle for when you want to have friends over, and its response time is just as good while being completely predictable across its entire refresh rate range.
The Samsung QN85C/QN85CD QLED is better than the Sony X90K/X90CK, except for image processing, where Sony is the market leader. The Samsung has a much better local dimming solution with many more zones, giving it a superior overall contrast ratio with much better black uniformity. It also gets much brighter in SDR and HDR and has a much better viewing angle. The Samsung TV also has four full HDMI 2.1 bandwidth ports versus only two on the Sony, one of which is its eARC port. Of course, the Sony TV has much better low-quality content smoothing and low-resolution upscaling and supports advanced audio and video formats such as DTS and Dolby Vision.
The Hisense U8/U8H is better than the Samsung QN85C/QN85CD QLED. The Hisense has much better contrast, helped by a better local dimming feature with less visible zone transitions and less blooming. The Hisense gets much brighter in both HDR, although the Samsung is just as bright in SDR. The Hisense is also more colorful, with a wider color gamut and better color volume. It also has better reflection handling than the Samsung, although the Samsung does have a much better viewing angle. Sadly, the Hisense has terrible image processing, and the Samsung is much better in that regard.
Test Results
The Samsung QN85C has a nice design, although it's nothing original, as it looks extremely similar, if not identical, to many of Samsung's other 2022 and 2023 TVs. But overall, the TV is sleek and feels well-built.
The Samsung QN85C's center-mounted stand is small and doesn't take up much space, so the TV doesn't require a large table or desk. The stand's small size doesn't stop the TV from wobbling, but it's not concerning.
Footprint of the stand on the 65" model: 15.4" x 11.3". The stand lifts the TV about 2.95" above the table, so most soundbars fit in front of the TV without blocking the screen.
The back of the TV looks good, with a nice textured design. There are cable channels on the back to help with cable management. There are also cable grooves in the stand, hidden with a cover, to further channel cables towards the stand's bottom and out of the TV. Note that the TV's inputs are in a recessed inlet on its back panel. They're hard to access if you wall-mount the TV with a fixed bracket.
The build quality of the Samsung QN85C is very good. The TV wobbles from front to back and from side to side due to its small stand, but it's not concerning. However, there's a large amount of flex near the TV's VESA holes and its inputs; nothing too worrying, but it's something to note. Aside from that, the TV feels sleek and is made from premium plastic.
The Samsung QN85C has a great contrast ratio. Its native contrast ratio is rather bad, but with local dimming set to high, the TV's contrast is superb; the TV can produce very deep blacks that don't look gray when viewed in a dark room. Note that as you can't fully turn off the local dimming on this TV at the moment, even through the service menu, we calculated the native contrast ratio using this inverse contrast pattern.
There's some noticeable blooming around bright highlights and subtitles in dark scenes, but it looks very good overall.
Lighting zone transitions on the Samsung QN85C are decent, but the algorithm that controls the local dimming feature can't quite keep up with fast content, so transitions are noticeable. When bright highlights move quickly across the screen, the leading edge is darker due to the TV not turning on zones fast enough. There's also a bright halo behind bright highlights that move quickly across the screen.
The TV's contrast and dark details in Game Mode are very good. The image is overall colder, i.e., has a blueish tint to it, than outside of Game Mode. As a result, colors really pop, and the contrast is very good, but it comes at the expense of a bit more blooming than in other modes.
The TV's HDR peak brightness is excellent. Small specular highlights stand out very well, and while large bright scenes are dimmer, they're still very bright. The TV's Automatic Brightness Limiter (ABL) isn't aggressive at all, so variations in brightness are kept to a minimum, although they're still there.
These measurements are after calibrating the HDR white point with the following settings:
- HDR Picture Mode: Movie
- Brightness: Max
- Contrast: Max
- Color Tone: Warm2
- Local Dimming: High
The TV's HDR peak brightness is very similar in Game Mode when compared to other modes, so it's excellent.
These measurements are after calibrating the HDR white point, with the following settings:
- HDR Picture Mode: Game
- Brightness: Max
- Contrast: Max
- HDR Tone Mapping: Static
- Local Dimming: High
- Color Gamut: Auto
- HDR10+ Gaming: Off
- Game HDR: Basic
The Samsung QN85C's PQ EOTF tracking is superb in 'Movie', 'Filmmaker', and 'Game' modes in HDR. It's overbrightened throughout, and its near-blacks are slightly raised. Aside from that, most content displays at the correct brightness level, respecting the content creator's intent. There's a sharp cutoff near the TV's peak brightness; this results in some clipping in really bright scenes, leading to a loss of fine detail.
The TV's SDR peak brightness is fantastic. It's bright enough to overcome glare in even extremely bright rooms with lots of natural light. The TV's Automatic Brightness Limiter (ABL) is not aggressive, although large bright scenes are still dimmer than scenes with smaller highlights. However, the TV is easily bright enough to overcome glare even when dimmed.
These measurements are after calibration with the following settings:
- Picture Mode: Movie
- Brightness: 50
- Local Dimming: High
- Color Tone: Warm2
The Samsung QN85C has a great color gamut. It can display almost the entire range of colors in the widely used DCI-P3 color space, so HDR content is vivid and lifelike, although most colors are slightly undersaturated. It has an okay coverage of the Rec. 2020 format, good enough for when it becomes more prevalent. However, this isn't the TV for you if you want strong Rec. 2020 coverage for future-proofing.
The Samsung QN85C has great color volume. It has bright, vibrant colors and can display bright colors very well. It can't quite display the most saturated colors, but it still does an excellent job for an ADS panel.
The TV has very good pre-calibration accuracy. Its white balance is slightly off, especially in very bright shades of gray, where blues are underrepresented. This explains the warmer white balance, which veers towards red. Its gamma tracking is excellent, almost exactly at our target of 2.2 for a moderately lit room, although dark scenes are slightly too dark.
After calibration, the TV has fantastic accuracy. Blues are stubborn and require some work to calibrate, but aside from that, it's not a hard TV to calibrate for. Still, dark scenes are still very slightly too bright, and bright scenes are a tad too dark.
You can see our full calibration settings here.
The TV has good gray uniformity. There's some vignetting, where the sides of the image are slightly darker than its center, and vertical banding is noticeable in content with large sections of bright colors, like when watching sports like hockey. Its uniformity with very dark colors is excellent, however.
The TV's black uniformity is amazing. Note that you can't turn local dimming completely off on this TV due to a more limited service menu, so we took the native black uniformity picture with local dimming set to 'Low'. With that setting, the TV's black uniformity is inadequate; there's a lot of blooming around the bright cross, going beyond it to give the whole screen a blue-ish tint. With local dimming set to 'High', the TV's black uniformity is exceptional.
The Samsung QN85C has a very good viewing angle. The colors wash out and lose some brightness at moderate angles, but overall it's good enough for a wide seating arrangement.
The TV has decent reflection handling. Its semi-gloss coating diffuses reflections across the screen, making them bigger but less bright.
The Samsung QN85CD has impressive HDR gradient handling. However, there's very noticeable banding in saturated greens, as well as in brighter blues.
The TV's low-quality content smoothing is acceptable. It does a decent job of preserving details, but it does a mediocre job smoothing out any macro-blocking in dark scenes.
The TV has good sharpness processing when upscaling content. It's good enough that low-resolution content looks sharp, although you'll lose some fine details in the process.
The Samsung QN85C uses an ADS-type panel, similar to the more commonly known IPS. It uses an RGB subpixel layout, so it won't have any issues rendering text when used as a PC monitor.
The TV has a good response time. Most transitions are very fast. However, it struggles in very dark scene transitions and has a lot of overshoot in those, causing inverse ghosting behind dark areas. Look at the Samsung The Frame 2024 QLED if you want a Samsung TV with a faster response time.
The Samsung QN85C uses pulse width modulation (PWM) to dim its backlight, so unfortunately, it's not flicker-free. The flicker frequency varies between picture modes and with certain settings.
It flickers at 960Hz in the following pictures modes between the stated backlight levels:
- Dynamic: between 26 and 46.
- Standard: between 25 and 47.
- Movie: below 48.
- No motion interpolation: always flickers at 960Hz.
- Game Motion Plus enabled: between 25 and 48.
All other modes and/or backlight levels flicker at 120Hz, except for Game Mode with LED Clear Motion enabled, which stays locked at 60Hz, and the 'Graphic' mode of 'PC' mode with the backlight set to Max, also locked at 60Hz.
The TV has an optional backlight strobing feature, commonly known as black frame insertion (BFI). The feature helps reduce blur caused by the TV's fast response time, otherwise known as persistence blur. It works at both 60Hz and 120Hz, which is great, but unfortunately, its timing is off, and it causes a duplicate image when enabled.
The Samsung QN85CD has a feature to increase the frame rate of low frame-rate content up to 120Hz. As is typical of this feature, it works very well with slow panning shots and other slow-paced scenes but shows a lot of artifacts once the action ramps up.
Due to the TV's good response time, low frame rate content, like movies, stutter a bit. It's mainly noticeable in slow panning shots, and motion interpolation or backlight strobing features can mitigate this to some degree, but they come with their own problems.
The Samsung QN85CD automatically removes judder from any source, with no additional settings needed. It's great for watching movies, as motion appears smooth.
The Samsung QN85CD is compatible with all three variable refresh rate (VRR) formats, and it works across a very wide refresh rate range, which ensures that your games remain nearly tear-free when gaming.
The TV has extremely low input lag in Game Mode. It results in a very responsive gaming experience, with very little delay between your inputs and the on-screen action. Unfortunately, the input lag outside Game Mode is too high for gaming or PC use.
The TV supports all common resolutions up to 4k @ 120Hz. All supported formats display chroma 4:4:4 signals properly, essential for clear text from a PC. There are no resolution-halving issues on this TV at any resolution, which is great.
The Samsung QN85CD can take full advantage of the PS5, with up to 4k @ 120Hz support on all HDMI ports and support for variable refresh rate (VRR).
The TV can take full advantage of the Xbox Series X or S, with up to 4k @ 120Hz support on all its HDMI ports and variable refresh rate (VRR) support.
The Samsung QN85C supports full HDMI 2.1 bandwidth on all four HDMI ports, making it very flexible for users owning multiple HDMI 2.1 devices. Unfortunately, Samsung still doesn't support Dolby Vision, instead supporting the less widely used HDR10+ format.
This TV supports eARC, which lets it pass uncompressed high-quality audio from a connected source to your receiver without sacrificing audio quality. Sadly, it doesn't support DTS audio formats, which is disappointing as many UHD Blu-rays and DVDs use DTS for their lossless audio tracks.
The TV's frequency response is okay. Like most TVs, there's barely any bass. However, the TV sounds sharp and clear at moderate volume, but when you raise the volume near or at max, the TV's sound reproduction shows noticeable compression, with dialogue not sounding as clear. Unfortunately, this TV doesn't get loud, so you might have to raise the volume near its max if you are in a loud environment.
The TV's distortion handling is okay. While its performance is good at moderate volume levels, distortion is more noticeable at higher volumes.
The Samsung QN85CD runs the 2023 version of Tizen OS, which is fast and easy to use. There's no lag whatsoever when using the Smart Hub interface, and finding your favorite content is easy.
Unfortunately, like most TVs on the market, there are ads throughout the interface, and there's no option to disable them completely. You can turn off targeted ads, but it doesn't reduce the number of ads you see; it just makes them less personalized to you.
The included apps cover most, if not all, of the common streaming services, and there's a great selection of additional apps available in Samsung's app store.
The TV comes with a slim remote that is easy to use. It's minimalistic, with few intuitively laid-out buttons. It has a built-in rechargeable battery which you can either charge through USB-C, with a port on the bottom of the remote, or through the solar panel on the back of the remote. The TV is compatible with Bixby and Amazon's Alexa, and both the remote and TV have integrated microphones. The voice commands work well; you can tell the TV to change inputs, ask it to open apps, or even change the brightness. Unfortunately, you can't search for content within apps using voice.
The button is under the Samsung branding on the bottom right of the TV. With it, you can turn the TV on and off, change the channel and the volume, and switch input sources. There's also a small toggle to turn the internal microphone on or off if you're worried about privacy.
