The Samsung QN900C 8k QLED is Samsung's second-highest TV in its 8k TV line-up. It sits below the company's flagship Samsung QN990C 8k QLED and above the Samsung QN800C 8k QLED. The TV replaces the Samsung QN900B 8k QLED and features the same technology as its predecessor, like Samsung's proprietary Quantum Mini LEDs that allow for more precise control of the TV's local dimming zones when compared to their regular Quantum Matrix Technology. It utilizes the same Neural Quantum Processor 8k as the QN900B, which uses AI and is designed to provide more detailed upscaling on a scene-by-scene basis. Like many of Samsung's previous QLEDs, the TV uses the external One Connect Box to help keep your setup tidy and organized. The TV is available in 65-inch, 75-inch, and 85-inch sizes.
Our Verdict
The Samsung QN900C is a great TV for mixed usage. It overcomes glare easily in a bright room thanks to its outstanding SDR peak brightness and excellent reflection handling, so it's great for watching TV shows or sports. It's also very good for use in a dark room due to its effective local dimming feature, so it's a good choice for watching movies. It's an excellent TV for gaming due to its incredibly low input lag and quick response time, so it delivers a responsive gaming experience that has very little blur behind fast-moving objects, and it has VRR support and HDMI 2.1 bandwidth, which makes it a great choice to pair with modern consoles or gaming PCs. The TV is also a great option for use as a PC monitor since it displays chroma 4:4:4 properly, and the viewing angle is wide enough that the sides of the screen stay uniform when sitting up close.
- Effective Local Dimming feature.
- Outstanding SDR peak brightness and excellent reflection handling to overcome glare.
- Good upscaling capabilities.
- Easy-to-use smart interface with a wide selection of streaming apps.

The Samsung QN900C 8k QLED is very good for watching TV shows in a bright room. The built-in Tizen smart interface is loaded with a big selection of streaming apps, so it's easy to find your favorite shows. The TV has outstanding SDR peak brightness and excellent reflection handling, so it easily overcomes glare in a bright room. It has an adequate viewing angle, so the image remains consistent when viewed from a moderate angle, but anyone watching from a more aggressive angle will see a washed-out image. The TV has good upscaling, which is extra important since 8k content is so rare, and most of the content watched on the TV needs to be upscaled. Unfortunately, the TV has unremarkable low-quality content smoothing, so there are still noticeable artifacts with low-quality streaming content.

The Samsung QN900C 8k QLED is great for watching sports. The TV has an amazing response time, so fast motion is clear, with no noticeable blur behind fast-moving balls and players. It also has outstanding SDR peak brightness and excellent reflection handling, making the screen easy to see in a bright room. The TV is a good choice for watching the game with a small group of friends since it has an adequate viewing angle, and the image remains consistent from a moderate angle. Still, it's not a great option for larger groups since anyone watching the game from a more aggressive angle will see a washed-out image. The TV's uniformity is great, so there's very little dirty screen effect when watching sports with large areas of the same color, like hockey or football.

The Samsung QN900C is very good for watching movies in a dark room. The TV has excellent peak brightness in HDR, so bright highlights pop. With the TV's very effective local dimming feature turned on, contrast is excellent, and blacks are deep and uniform, but there's some blooming around subtitles and other bright objects when they are against a dark background. The TV has a wide color gamut, so it displays a wide range of colors, and those colors appear vibrant and bright due to its impressive color volume. Unfortunately, there's noticeable banding with similar shades of certain colors when they are next to each other on screen. The TV supports HDR10+ but lacks Dolby Vision support. It has unremarkable low-quality content smoothing, so there are still noticeable artifacts present with low-quality content.

Popular TV Comparisons
The Samsung QN900C is an excellent TV, but its aggressive automatic brightness limiter (ABL) and only adequate viewing angle are disappointing. Since 8k content is still very rare, an 8k TV isn't worth it for most people, and you can get similar performance from a 4k TV like the Samsung QN90C/QN90CD QLED for much cheaper.

The Samsung QN900D 8K is an incremental improvement over the Samsung QN900C 8K. The newer QN900D has slightly better contrast, gets a bit brighter in HDR, and is capable of 4k @ 240Hz and 8k @ 60Hz with full VRR support. The QN900C is, however, slightly brighter in SDR content, but overall, the QN900D has the edge in every other metric.
The LG G3 OLED and the Samsung QN900C 8K are better for different uses. The LG is better in a dark room due to its nearly infinite contrast ratio, better black uniformity, no blooming, and perfect zone transitions, so you get perfect blacks with no distractions. The LG also has better HDR gradient handling for less banding, and its wider viewing angle makes it a better choice for watching TV with other people, as no one will have to watch a washed-out image. The LG also has better PQ EOTF tracking and a wider color gamut, so the image is closer to the creator's intent, and HDR colors are a bit more vibrant and lifelike. The Samsung is better for a bright room due to its higher SDR peak brightness, so it overcomes glare better. The Samsung is also capable of 4k @ 144Hz, so it's a better option for a gaming PC capable of 144 fps.
The Samsung QN900C 8K and the Samsung QN900B 8K are very similar TVs, and you'd be hard-pressed to notice a difference between them. The QN900C has a dark gray stand that better matches the rest of the TV than the silver stand found on the QN900B. Even though it's an older model, the QN900B has slightly better contrast, and it gets a bit brighter in HDR than the QN900C, so if you primarily use your TV in a dark room and you can find the QN900B on sale, it's the better buy for that purpose. The QN900C has better PQ EOTF tracking, so if you're after accuracy, it's the better option.

We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.
