I own a TCL Roku TV Model 32S357, which supposedly supports FHD. You know, 1080p? But only the stuff plugged into the HDMI ports, like a streaming device or a game system, displays 1080p. The apps on the TV itself? They only go up to 720p. I know this because I checked the "Stats for nerds" on a YouTube video, and next to "Viewport/Frames", it said 1280x720. I'm pretty sure that means 720p.
How do I change the viewport to 1080p like it's supposed to? Every other article said go to Display in the system settings, but that only appeared in the Roku streaming devices. How do I change display settings on my TCL Roku TV Model 32S357? I cannot stress this enough, I am NOT talking about Roku Streaming devices.
