The second set of numbers indicates the model series. The higher the number, the more premium the TV is. Three digits refer to 8K models, while two digits relate to 4K models. Percentage luminance drop at 20 degree vertical angle from the centre of the screen with 50% white output Samsung’s anti-glare screen coating for the QN90C series proved effective at keeping screen reflections to a minimum. Between that and the TV’s high brightness, the QN90C will be a great option for daytime sports viewing. The company’s Ultra Viewing Angle tech also helped images retain contrast and color saturation when viewed at off-center seats – a performance aspect that gives the QN90C an advantage over budget LCD TVs, most of which start to look washed out when you move away from a center viewing position.
I measured input lag at an impressive 9.4ms (1080/60), in Game mode. With Game Motion Plus engaged, which retains some image enhancing processing, this drops to 25ms. Picture Quality Percentage luminance drop at 20 degree vertical angle from the centre of the screen with 100% white output Samsung describes the QE50QN90B as a Neo QLED model, alerting us to the fact that it uses Quantum Dots to generate its colours rather than colour filters. This should, if other aspects of the TV are also up to snuff, result in a wider and more subtle colour gamut well suited to the extra colour range that typically accompanies high dynamic range content. C: This refers to the year of manufacture. Samsung has skipped a number of letters in recent years but A indicates 2021, B 2022, and C 2023. The color balance in the Movie picture mode’s default Warm color temperature setting was slightly blue-ish, with Delta E values at some brightness levels measuring in the 3-4 range (we typically look for these to dip below 3). Measurements made with Portrait’s Calman color calibration software also showed coverage of DCI-P3 (the color space used for mastering 4K Blu-rays and digital cinema releases) to be 93.3%, and BT.2020 to be 73.0%. These are just average results, with sets from budget brands like TCL and Hisense delivering equivalent performance.One of the reasons the QN90A is a bit more unstable this year is because it’s a bit thinner. Compared to last year, Samsung shaved about half an inch from the depth from the TV which has meant making some compromises on sound quality and stability. That’s not a bad thing if you plan on connecting the TV to an external sound system – like one of Samsung’s Dolby Atmos soundbars – and wall-mounting the TV, but it’s all worth noting.
QN: This relates to the range – QN being the company’s Neo QLED range. S represents the QD-OLED range. As stated above, the QN90B series features Samsung’s Neo Quantum processor 4K. It supports the HDR10, HLG and HDR10+ high dynamic range formats, along with HGiG ( HDR Gaming Interest Group), but, as with past Samsung sets, Dolby Vision HDR has been left out in the cold.

If you don’t want to use AI and you don’t want to fiddle with the EQ, you can use the Amplify setting to get an uplift in mids at low volumes, which does help alleviate some problems. When we had the TV fully set up on the stand, with screws fastened as tight as possible, there was still a reasonable amount of wobble to the TV. It wasn’t as bad as the Sony X950H that we lambasted last year for its shakiness, but it’s still much less stable than we’d like. Of course, we can only speak about the 65-inch version of the TV that we had in for testing – the 55-inch TV might be totally fine with its lower weight and center of gravity. Viewing another reference scene on 4K Blu-ray, this one from Dune (2021), as Paul and his mother walk through a dark, misty space following an interrogation, the QN90C’s picture looked clean and crisp despite the grainy nature of the images. The set’s performance here was a big improvement over last year’s QN90B, which showed a high level of noise in this same scene when I did a hands-on test of it. Streaming apps in the TV's smart interface occupy a horizontal row that can be fully customized. (Image credit: Future) Samsung QN90C TV review: smart TV & menus
