The Samsung QN900B 8k QLED is Samsung's flagship 8k TV released in 2022, sitting above the Samsung QN850B 8k QLED and the Samsung QN800B 8k QLED and replacing the Samsung QN900A 8k QLED. It features much of the same technology as the Samsung QN95B QLED, including a Mini LED backlight, allowing for higher peak brightness and finer control of the local dimming zones. Like the QN95B, it uses an external One Connect box instead of traditional inputs, which helps keep your setup neat and organized. It uses Samsung's new Neural Quantum Processor 8k, which is designed to deliver better upscaling, optimized on a scene-by-scene basis, and it's one of the first TVs on the market to offer a 144Hz refresh rate for PC gamers. It has been replaced in 2023 by the Samsung QN900C 8k QLED.

Popular TV Comparisons
The Samsung QN900B is a great TV but has disappointing contrast and a lackluster local dimming feature, especially for the price. It delivers similar performance to most of the other recent 8k TVs like the TCL 6 Series/R648 2021 8k QLED, but 8k still isn't worth it for most people, and there are many 4k TVs out there that offer better value for less.

The Samsung QN900B 8K is slightly better than the Samsung QN800A 8k QLED. The QN900B has a much better local dimming feature, with significantly less blooming around bright objects. The QN900B is also better for gaming, especially for PC gamers, as it has a higher max refresh rate and better motion handling, with less blur around fast-moving objects.
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.
The Samsung QN900B 8K is slightly better than the TCL 6 Series/R648 2021 8k QLED. The Samsung gets a lot brighter, especially in HDR, and small highlights stand out better. The TCL has a higher native contrast ratio, so blacks look better with local dimming disabled, but the Samsung TV's local dimming feature is more effective at boosting contrast. The Samsung is also better for gaming, with a faster response time and support for HDMI 2.1 bandwidth on all four inputs instead of just two on the TCL.
The Samsung QN900B 8K is a slight improvement over its predecessor, the Samsung QN900A 8K. The QN900B has a higher max refresh rate, which is great for PC gamers, and it has a faster response time, so motion looks smoother with less blur around fast-moving objects.
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.
