“I’m looking to upgrade from a Roku player to Apple TV. I know the tv is 720p but noticed that the resolution says 1080p with the Roku connected through the hdmi, will it upscale to 4K if I get the 4K Apple TV?”

Resolution basically refers to the number of pixels that can light up on the display. 720p means 1280 x 720 pixels or 921600 total pixels. The screen cannot light up more pixels than it physically has so it will max it at 720 regardless. When it shows 1080 that's just telling you the source is 1080 but the screen does not have enough pixels to display 1080 so it still displays 720. There is no upscaling. Upscaling can only happen if the screen you have has a higher resolution than your source. For example a 4k screen and a 720p source. Upscaling does not work in reverse. TLDR: It will not upscale to 4k if you attach an apple tv. It does not actually display 1080p when you connect the roku.
Sorry, there was a problem. Please try again later.No, this TV will definitely not have the capability to change to 4K resolution regardless of the devise you are using with it.
