Since 1982, PCMag has tested and rated thousands of products to help you make better buying decisions. See how we test. Starting out viewing test patterns via a 4K signal generator and the Spears & Munsil UHD HDR Benchmark disc, a full-screen 100% white pattern and a lower-level gray one both showed a slight amount of color tinting and non-uniform brightness, though I can’t say I noted the same issue when watching regular programs. Better news: the QN90B was able to retain brightness and color vibrancy at viewing positions up to 45 degrees off from center, proving the effectiveness of the Ultra Viewing Angle feature. I was also impressed by how good pictures looked with overhead lights on – that anti-glare screen in action – though I did most of my evaluation with room lights switched off. Updated text for clarity throughout to match the results after various Test Bench updates. Also confirmed that 1440p works with the PS5. What’s more, despite the sophistication of its processing engine and lighting system, the QE50QN90B manages to get the time it takes to render images in its Game mode down to a hugely impressive 9.6ms (with 1080p/60Hz signals). Samsung’s Game Bar does, though, provide the option to sacrifice a bit of screen response speed in return for better, processing-assisted picture quality, along with other game-related adjustments such as the ability to raise the brightness of dark areas without impacting the rest of the picture so that you can more easily see enemies lurking in the dark. The QN90B’s maximum picture brightness measured on a 10% white window in Dynamic mode was in the 2,000 nits range – way more than enough to deliver the goods with most HDR content. Other measurements showed input lag with a 4K test signal generator to be an excellent 9.8ms (milliseconds) and 12ms with a 1080p source, both in Game mode.

We updated the text in the PQ EOTF box, as the results changed with our recent change in test methodology. With an HDR signal, the QN90B shows a peak brightness of 612.132cd/m If you’re wondering at this point how Samsung’s QN90B range differs from the more expensive QN95Bs, aside from tweaks to the design the only really significant thing is that the QN95B uses an external connections box, while the QN90B’s connections are built into the TV’s bodywork. Note, too, that there’s no 50-inch QN95B; that step-up range begins at 55 inches.There are four HDMI inputs (HDMI 3 supports eARC for passthrough of audio to a soundbar), digital optical out, CI+ 1.4, two satellite tuners, an aerial antenna, two USB ports and an ethernet for hardwired connection to the internet. If you want to connect wirelessly to the TV there’s Bluetooth 5.2 and Wi-Fi, along with DLNA and Samsung’s Wireless Dex support. Picture Quality When it comes to gaming the QN90B is not as all-consuming as the LG C2’s feature set but you’re still getting a tremendous number of features whether you’re a console or PC gamer. I measured latency at 10.1ms – faster than the LG C2 (13.1ms) – and with Variable Refresh Rate (VRR) that can drop down to neglible amounts.

While the QE50QN90B joins other Samsung 2022 smart TVs in excelling on content quantity, though, it also labours under the same unhelpful new interface design. This can be sluggish when the TV is first switched on, can be confusing to navigate, and has a tendency to highlight content most people won’t actually be interested in. That pricing puts it in among the LG OLED55C2, Philips 55OLED807 and Sony XR-55A75K as competing options. Design The QN90B's glare-resistant screen lets it look good even with overhead room lights on (Image credit: Future / Al Griffin) Design and featuresAll of the QE50QN90B’s high-end picture features are marshalled by the latest version of Samsung’s Neo Quantum 4K video processor, complete with improved upscaling and the accumulated knowledge of numerous neural networks that have been busy crunching through countless image types in Samsung’s labs to develop a vast database of picture optimisation shortcuts.
