If you are currently using a screen smaller than 43 inches or sitting more than 10 feet away from a medium-sized TV, the jump to UHD might feel subtle. However, if you are looking to upgrade to a , or if you are a gamer using a PS5 or Xbox Series X , UHD is no longer an "extra"—it is the baseline requirement to see what those machines are actually capable of producing.
