Samsung 50 Inch QN90B Neo QLED 4K Smart TV (2022) - Neural Quantum 4K Processor With 144Hz Gaming Refresh Rate, Dolby Atmos Surround Sound & Alexa Built In, 100% Colour Volume & Ultrawide Game Mode

Product Information

While the QN90B’s advances over the QN90A might not earn it as many headlines as its predecessor, its picture improvements are targeted and effective. The addition of Dolby Atmos to the QN90B’s audio talents, too, brings it more in line in audio terms with most premium TV rivals.

Both the QN90B and QN90A are among the best TVs available today, but let’s go through all the differences, to help you decide which is best for you. Samsung QN90B vs QN90A: Price and sizes We uploaded the brightness measurements and uniformity photos after running the TV for four months in our Accelerated Longevity Test. Both of these potentially significant new picture advantages are powered by an even more powerful version of Samsung’s AI-based picture analysis/processing system. This is able to draw on the accumulated picture analysis knowledge of a massive 20 neural networks versus the 16 deployed for the QN90A, delivering even more accurate, effective and natural enhancements to every image. Updated text for clarity throughout to match the results after various Test Bench updates. Also confirmed that 1440p works with the PS5.The entire process is slow and clunky, if a necessary evil given the remote’s limitations (see the next section). Other interfaces are much more user-friendly, some (particularly Google TV) while offering you even more up-front information and better suggestions about what to watch. Does Tizen get the job done? Yes, but Samsung could do better, and hopefully will in the not-too-distant future. Samsung QN90B Neo QLED TV: Remote If a TV gives you a good picture, you want good audio to go with it, and most TVs fall short in that area. The smaller QN90B does not, though it’s not really anything to writing home about, either. We uploaded the latest brightness measurements and uniformity photos for the Accelerated Longevity Test. Picture-wise, the 43-inch QN90B disappoints in three ways. First, like other Samsung TVs, it doesn’t support Dolby Vision, so you won’t get the most out of movies and TV that do. Its off-angle viewing isn’t the worst, but the screen’s colors lose a lot of their inherent richness and take a grayish cast if you’re positioned too far from the center of the screen in any direction. (Samsung touts a feature on the QN90B line called Ultra Viewing Angle, which is supposed to mitigate this, but it is included only on the 50-inch and larger models.) Because this is a smaller set, that’s unlikely to be a critical problem, but keep it in mind. It also has a little bit of trouble generating fine detail in some of its picture modes: In Cinema and Filmmaker, fine details occasionally get a little mushy in a way they don’t in Standard and Dynamic. (This was particularly evident in all the 1-pixel sections of one of our chief 4K test patterns.) Sit far enough away, and you’re unlikely to notice, but it has the potential to distract if you’re too close. Samsung QN90B Neo QLED TV: Audio We discovered a flaw with the equipment used to force an HDR signal when measuring color volume and the color gamut. We've switched to a new tool and updated our measurements. The color gamut and volume have changed slightly.

We uploaded the initial brightness measurements and uniformity photos for the Accelerated Longevity Test. The QN90B range also includes six models, but tops out at 85 inches rather than 98. The other five QN90B screen sizes match those of the QN90A range. We uploaded the brightness measurements and uniformity photos after running the TV for two months in our Accelerated Longevity Test.We updated the text in the PQ EOTF box, as the results changed with our recent change in test methodology. Some may feel a little disappointed by this – especially the apparent failure to substantially increase the number of dimming zones. We’ve seen plenty of evidence with premium ‘regular’ (not mini-) LED TVs, though, to know that it’s not always the number of dimming zones that counts; it’s what you do with them. And on that front, the new Samsung QN90B has a very promising new feature to shout about: Shape Adaptive Light Control. Converted to Test Bench 1.10. With this update we've revamped our Gradient testing, added a new test for Low Quality Content Smoothing, and expanded our Audio Passthrough testing.
