The Samsung QN90A QLED is the best LED TV we've tested. It's a feature-packed model that delivers exceptional picture quality in dark and bright rooms. It's different from other LED TVs because it uses Mini LED backlighting, featuring lots more smaller LED backlights behind the LCD than a traditional LED-backlit TV. It allows greater control over the local dimming feature for better dark room performance.
  Another advantage of the Mini LED backlighting is how bright the TV gets. With its outstanding reflection handling, visibility won't be an issue even in the brightest rooms. Even if you want to use it in a room with a wide seating arrangement, it's a good choice because it uses Samsung's 'Ultra Viewing Angle' technology to provide wide viewing angles despite having a VA panel. It means that the image remains fairly accurate when viewed from the sides. If you don't want to spend extra on a streaming box, you'll be happy to know the built-in Tizen OS is easy-to-use and has a ton of apps available to download.
  Unfortunately, it has some uniformity issues with dirty screen effect in the center. It gets distracting while watching sports with large areas of bright colors, like hockey or basketball, or if you want to use it as a PC monitor. If that's not the case for you, then it's the best LED TV we've tested.
