SAMSUNG Neo QLED 4k: Review and Specification

Samsung QN90A QLED is the flagship 4k LED TV. This is part of Samsung’s Neo QLED 2021 lineup, which combines a Mini LED backlight with a quantum dot layer to display a wide range of colors at different brightness levels. The Mini LED backlighting helps the TV show deeper blacks because the TV has better control over local dimming, and the TV also adds brightness, enough to combat glare or reflections. It comes with the Tizen smart platform, which is easy to use and has a lot of apps to download, and the new remote has a solar panel on the back, so it uses sunlight. heaven to charge. It comes with a bunch of gaming features like variable refresh rate (VRR) support and HDMI 2.1 bandwidth, but it’s only on one port, which is disappointing since you can’t fully experience the two. Next-generation console at the same time.

Samsung’s Tizen OS has reached version 6.0, with new features like Game Bar, Samsung Health (training app), PC on TV (for easy PC connection), and Google Duo (video calling). As always, Tizen 6.0 is reserved for 2021 models. Samsung still refuses to provide major Tizen updates for earlier TVs. The company also doesn’t commit to providing Tizen upgrades for its 2021 models.

The TV is easy to set up with or without a smartphone app included, but you end up spending too much time entering app logins. Right after setup, you’ll be greeted by Rakuten, which supports Samsung’s TV Plus app in many regions – and the app experienced serious lip-syncing issues in our QN95A.

Picture Quality

For the first time, Samsung uses miniLED backlighting in its high-end LCD TVs, just like TCL. To signal the change, Samsung has started promoting its best LCD TV as “Neo QLED.” MiniLED by itself doesn’t offer better picture quality. The most important factors in determining/improving the picture quality of an LCD TV are still the type of panel (VA or IPS) and the number of dimming zones (and how the zones are controlled).


Samsung typically has fewer picture modes than TVs from other brands – which is a good thing – but still too many. In addition to the usual suspects (Standard, Dynamic, Game, Movie, and Nature), Samsung added ‘Movie Maker Mode’, which should have replaced the ‘Movie’ mode as they are more or less the same together. Samsung may also remove “Natural” and “Dynamic” because “Standard” is still very vivid.

The only picture modes with relatively accurate colors are ‘Movie’ and ‘Moviemaker Mode’, and these are the modes we recommend for viewing SDR and HDR on Samsung TVs. With some 2-point teak, we managed to make things even better, as shown in the chart below. We also include correction recommendations (for SDR) in the table below. Samsung TVs support Calman AutoCal, if you have the hardware and software.

Meanwhile, Samsung’s “Game” mode is an exercise in poor picture quality. It was so extreme that my eyes hurt. Even in SDR, brightness went up to over 1600 nits, which was not only extreme but unhealthy, and colors spread across the TV’s native color space, creating a bold and oversaturated picture. peace. And the very high color temperature pushes everything toward blue. In Game HDR mode, Samsung adjusted the PQ luminance curve to making all games look too bright – just wrong (see examples in the picture quality section). The whole idea of ​​increasing color and brightness in “Game” mode is very strange. Game developers go to great lengths to make sure their games look good, so why would a TV maker actively try to make things look bad? This is the worst “Game” mode of any TV I can remember. Note that Game Mode must be enabled from the General menu (or New Game Bar) instead of the Picture Mode menu. As for HDR, we measured DCI-P3 and Rec.2020 coverage at 94% and 70%, a good step up from last year’s disappointing Samsung Q95T/Q90T (coverage, respectively). 87% and 64%) but still slightly below the best OLED TVs. On the other hand, Samsung’s LCD TVs manage to maintain color saturation at higher brightness levels (compared to the WOLED panel of all OLED TVs).


Last year, Samsung downgraded its high-end 4K LCD TVs, ostensibly to make 8K LCD TVs more appealing. FlatpanelsHD criticized the decision, so we’re pleased to announce that Samsung has taken that criticism into account and reversed its course. The Samsung QN95A/QN90A is a significant upgrade over last year’s Q95T/Q90T, and the picture performance is more in line with 2019’s Q90R. Not because of the mini LED but because of the number of dimming zones. On the other hand, “Neo QLED” is still in full bloom. Tizen remains a consistent TV platform, and its minimalist bottom menu provides quick access to streaming apps that look even more appealing after LG ditched its bottom menu in favor of full-screen webOS user interface. Samsung’s new “Game Bar” feature is nice, but other than that, there’s not much new to report about Tizen. Samsung’s continued refusal to provide Tizen OS updates for earlier models is being criticized, and the 2021 models will also remain stuck on Tizen 6.0.

Samsung’s QN9xA TVs come with HDMI 2.1 (one or four ports, depending on model) for 4K120 and VRR, but gaming performance is degraded by the ugly “Game” mode, which is extremely changing the experience. At the same time, the dimming system is significantly reduced in Game mode. Some may find that the QN90A/QN95A’s low input lag, game bar, and low burn make up for this.
