If thats your go-to HDR format, this TV might fall short. Additionally, while it does come with an ATSC 1.0 tuner for live TV, it skips ATSC 3.0, so you wont get newer over-the-air 1080p or 4K broadcasts. For most people, thats not a dealbreaker, but if you rely on an antenna instead of streaming, its worth keeping in mind.At 50 inches, this TV is best suited for a living room or bedroom where youre sitting maybe six to eight feet away. It runs on Samsungs Tizen OS, which can be a bit cluttered if youre not used to Samsungs smart TV interface, but it does support all the major apps out of the box, including Netflix, Prime Video, and Disney+. You can also stream straight from your iPhone, iPad, or Mac using Apple AirPlay, and it also works with Miracast or WiDi if you want to mirror your Windows PC. Amazon Alexa is built in, and thanks to the far-field microphones, you can use voice commands without picking up the solar-powered remote. Gaming-wise, the TV's 120Hz refresh rate push up to 144Hz with VRR and supports AMD FreeSync Premium Pro.
