The SAMSUNG S90D, also known as the S94D, is a device that has repeatedly pleasantly surprised us during our tests. It is worth mentioning that depending on the chosen size, the differences may concern the OLED panel used. However, regardless of which variant we encounter, one can count on excellent black levels and HDR effects, which, thanks to high brightness, make a huge impression. This is one of those TVs that really can elevate home viewing to a cinematic level. While testing films and series, we immediately noticed the great colour reproduction and depth of black. Dark scenes, which can be problematic on other screens, are full of detail and immersive here. Although the factory colour settings could be a bit better, after calibration the picture gained clarity, and the television showed what it is truly capable of. In terms of everyday use, we noticed that the wide viewing angles allow comfortable viewing even from less central positions. The Tizen operating system appealed to us – it is clear, fast, and offers access to the most popular applications. AirPlay works flawlessly, which was a nice addition during our tests. And what about picture fluidity?... The 144 Hz panel performs excellently. While watching sports, the image was smooth, with no hint of motion blur. Matches and races felt as if we were really in the stands. We also couldn't overlook the gaming tests. Low input lag and HDMI 2.1 support make the S90D/S94D an excellent choice for gamers. Games ran smoothly, and every movement was displayed with incredible precision. This is equipment that meets the expectations of even the more demanding console users. The SAMSUNG S90D/S94D is a television that combines excellent picture quality with modern features and versatility. Whether we are watching films, playing on a console, or simply using applications, this model impresses. In its price range, it is truly a strong contender.
