The Samsung QN90C/QN90CD QLED is a high-end 4k TV released in 2023. It replaces the Samsung QN90B QLED in Samsung's lineup, but it has more in common with the Samsung QN85B QLED. It's available in a wide range of sizes, from 43 to 85 inches, so there's something for everyone. It's powered by Samsung's Neural Quantum Processor 4k, which was first introduced in 2022 and is designed to deliver better upscaling, optimized on a scene-by-scene basis. Like other Samsung TVs, it uses Samsung's proprietary Tizen OS interface, which offers a large selection of apps and games. It's compatible with the Bixby and Alexa voice assistants, and it supports the new Matter smart home standard, so you can control all of your Matter-compatible smart devices from your TV.

Differences Between Sizes And Variants

We bought and tested the 65-inch Samsung QN90C, and these results are also valid for the 55-inch, 75-inch, and 85-inch models. The 43-inch and 50-inch models are slightly different, as they use VA panels and have a slightly higher refresh rate. It's also sold as the Samsung QN90CD at warehouse retailers, including Costco. The CD variant has slightly better speakers and a longer warranty but otherwise performs the same. Note that the last five letters in the model number (AFXZA in this case) vary between retailers and individual regions, but there's no difference in performance.

There are also variants of this TV with a different model code. The QN91C, QN92C, QN93C, and QN94C are available in a few different regions, each with small variations from the QN90C. For example, the manufacturer markets the QN92C and QN94C as having Ultimate UHD Dimming Pro Micro Dimming, theoretically providing them with slightly better local dimming than the QN90C. The QN92C also has 70w speakers versus 60w for the QN90C and QN94C. Ultimately this won't impact your purchasing options much, as these differences are regional, but note that there are some minute differences.

Compared To Other TVs

The Samsung QN90C is an excellent TV that delivers fantastic picture quality overall. It's pricey, but there are very few TVs on the market that even come close to offering the same combination of picture quality and extra features.

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

Samsung QN90B QLED
43" 50" 55" 65" 75" 85"

The Samsung QN90B QLED is a bit better than the Samsung QN90C/QN90CD QLED, but the QN90C has a few advantages over the previous model. The QN90C has better tone mapping and tracks the PQ EOTF better, so HDR content especially looks better, despite the QN90B's better measurements on some aspects of picture quality. The QN90C also uses a different panel type that natively has a wider viewing angle without needing additional filters, so there's no Ultra Wide Viewing Angle layer. It results in a slightly smaller viewing angle on the QN90C, but there's no distracting rainbow smearing from overhead lights.

LG B2 OLED
55" 65" 77"

The LG B2 OLED and the Samsung QN90C/QN90CD QLED offer different strengths and weaknesses, so the best one depends mainly on your viewing conditions. The LG looks much better in a dark room thanks to its nearly infinite contrast ratio, resulting in perfect blacks with absolutely no blooming around bright highlights. The Samsung, on the other hand, is a much better choice if you're in a bright room or have a lot of windows, as it gets significantly brighter and can better overcome glare.

LG C2 OLED
42" 48" 55" 65" 77" 83"

The LG C2 OLED and the Samsung QN90C/QN90CD QLED offer different strengths and weaknesses, so the best one depends mainly on your viewing conditions. The LG looks much better in a dark room thanks to its nearly infinite contrast ratio, resulting in perfect blacks with absolutely no blooming around bright highlights. The Samsung, on the other hand, is a much better choice if you're in a bright room or have a lot of windows, as it gets significantly brighter and can better overcome glare.

Samsung QN90A QLED
43" 50" 55" 65" 75" 85" 98"

The Samsung QN90A QLED performs better than the Samsung QN90C/QN90CD QLED on a few tests, but overall, the QN90C looks a bit better, especially with HDR content. The QN90C has better tone mapping and tracks the PQ EOTF better, so HDR content looks better and is more accurate. The QN90C also uses a different panel type that natively has a wide viewing angle without neding additional filters, so there's no Ultra Wide Viewing Angle layer. It results in a slightly smaller viewing angle on the QN90C, but there's no distracting rainbow smearing from overhead lights.

The Samsung QN90C has a premium design that looks great in any setting. The slim hexagonal stand looks great and takes up very little space. The bezels are incredibly thin, which helps the TV to blend into your surroundings.

Stand

The stand is thin and doesn't take up much space. Unfortunately, it doesn't support the TV well, as it wobbles a lot.

Footprint of the 65-inch stand: 2.48" x 2.59". The stand lifts the TV about 2.95" above the table, so most soundbars fit in front of the TV without blocking the screen.

Back
Wall Mount VESA 400x300

The back of the TV looks great, with a nice textured design to the back panel. There are grooves along the back to help with cable management. The inputs are hard to access, especially if you wall-mount the TV. You can mount it to any standard VESA mount, and it's also compatible with Samsung's Slim Fit Wall-Mount.

Build Quality

The Samsung QN90C has great build quality. It's made of a mixture of metal and premium plastic, and it feels nicely built overall. The stand isn't very sturdy, though, and the back panel has a lot of flex to it. There's also a gap between the back panel and the inputs that shouldn't be there; this could indicate a quality control issue, but won't likely cause any issues long term.

Thanks to its Mini LED local dimming feature, the Samsung QN90C has excellent contrast. It results in very deep blacks in a dark room, even when bright highlights are visible on the screen. The native contrast with local dimming disabled is very low, but this isn't an issue since you can only disable it from the service menu anyway.

There's some noticeable blooming around bright highlights and subtitles in dark scenes, but it still looks great. Samsung's dimming algorithms spread bright lights across more dimming zones than necessary, so it's not as harsh as other TVs.

Unfortunately, the algorithms that control the local dimming feature can't quite keep up with fast content, so zone transitions are noticeable. When bright highlights move quickly across the screen, the leading edge is darker, as the TV doesn't turn zones on quickly enough. There's also a bright trailing halo behind fast-moving objects. We took additional videos with a mouse cursor on a black background with local dimming set to 'Low' and 'High':

The Samsung QN90C has superb peak brightness in SDR. It's bright enough to overcome glare even in extremely bright rooms with lots of natural light. Large, bright scenes are dimmed considerably by the TV's automatic brightness limiter, but it's still bright enough to overcome glare, and this isn't noticeable with most content.

The Samsung QN90C has amazing peak brightness in HDR. Bright specular highlights stand out incredibly well, even in difficult scenes with a high APL (Average Picture Level). Although it doesn't get quite as bright as the Samsung QN90B QLED, it tracks the PQ EOTF better, and most HDR content looks better and more natural on the QN90C.

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

  • HDR Picture Mode: Movie
  • Brightness: Max
  • Contrast: Max
  • Color Tone: Warm2
  • HDR Tone Mapping: Static
  • Local Dimming: High

Setting HDR Tone Mapping to 'Static' delivers the most natural image, closest to the content creator's intent. If you prefer a brighter image, setting it to 'Active' results in brighter highlights, and most content looks brighter, closer to the Samsung QN90B QLED, but the peak brightness is the same.

With the 'FILMMAKER' and 'Movie' modes in HDR, the Samsung QN90C has superb PQ EOTF tracking, ensuring that most content displays at the correct brightness level. There's a sharp cutoff near the TV's peak brightness; this results in some clipping in really bright scenes. Setting the HDR Tone Mapping setting to 'Active' noticeably increases the brightness of most scenes, but doesn't change the overall peak brightness of the TV ('Movie' Mode, 'FILMMAKER' Mode).

Unlike some previous Samsung TVs, there's no noticeable difference in PQ EOTF tracking with different test window sizes. This means that you'll enjoy an accurate image when watching HDR content, and Samsung isn't optimizing their TVs for reviewers.

The Samsung QN90C has good gray uniformity. The sides of the screen are slightly darker than the center, and there are some darker spots throughout the center of the screen. It still looks good when watching sports or browsing the web, though. Near-black uniformity is much better, with no significant issues in dark scenes.

The Samsung QN90C has a decent viewing angle. The image remains consistent at a moderate angle, but if you move too far off-center, colors fade, and the screen looks washed out. It's good enough for a moderately wide seating arrangement, as you can move around the room without the image degrading. Due to the switch from VA panels to an ADS (IPS-like) panel, the 2023 QN90-Series TVs no longer feature an ultra-wide viewing angle layer.

This TV has superb reflection handling. The glossy coating looks great and significantly reduces the intensity of direct reflections. Since Samsung switched their 90-Series TVs to ADS (IPS-like) panels, there's no ultra-wide viewing angle layer, so the rainbow distortion that was noticeable on other TVs, like the Samsung QN90B QLED, is no longer an issue.

The Samsung QN90C has a great response time, resulting in fairly clear motion when gaming or watching sports. There's some blur around fast-moving objects but almost no overshoot that could result in inverse ghosting.

PWM Dimming Frequency
960 Hz

Unfortunately, the backlight isn't flicker-free, as Samsung uses pulse width modulation (PWM) to dim the backlight. The exact flicker frequency varies between picture modes and with certain settings. In 'Movie' mode, with the backlight set between '48' and the max of '50', the backlight flickers at 120Hz. However, it increases to 960Hz with a backlight setting below '48'. The flicker frequency drops to 120Hz in the 'Dynamic' mode with a backlight above 25, in 'Standard' mode above 21, and in 'Eco' mode above 25. If you're using it as a PC monitor, it flickers at 120Hz in both 'Entertain' and 'Graphic' modes and flickers at 960Hz in 'Game' mode below 48. Between 48-50, it's flicker-free in 'Game' mode, and it always flickers at 960Hz with the variable refresh rate feature enabled in 'Game' mode from a PC.

This TV has an optional backlight strobing feature, commonly known as black frame insertion or BFI. This feature reduces blur caused by the TV's fast response time, otherwise known as persistence blur. It works at both 60Hz and 120Hz, but the timing is a bit off, causing a duplicated image.

This TV has a feature to increase the frame rate of low frame-rate content like movies and TV shows. It's okay overall on this TV, but it looks best in slow-paced scenes. Like most TVs, it doesn't look as good in busy scenes with a lot of action, and there are a lot of artifacts.

Due to the quick pixel response time, low frame rate content, like movies, appears to stutter. It's mainly noticeable in slow panning shots. If this bothers you, the optional motion interpolation or backlight strobing features can help, but those features create other issues, so there's no perfect solution.

The Samsung QN90 has an okay frequency response. Like most TVs, there's almost no thump or rumble in its bass, so if you enjoy explosions and action movies, even a basic external soundbar or home theater system with a dedicated subwoofer delivers better sound. The sound profile is well-balanced above its low-frequency extension at moderate listening levels, meaning that dialogue is clear and easy to understand. Unfortunately, although it gets fairly loud, there's significant compression at max volume, especially in the mid-to-high treble range.
