I just plugged my PC with windows 10 into an RCA HD tv via HDMI. When I switched over to the proper source it read "1080x1920" and the windows logo is clearly high def, but after about 5 seconds the screen refreshed and read 1080p only and the resolution looks crappy. I have my PC display setitngs at 1080x1920, same with Nvdia Control Panel. My drivers for my monitor and GPU are up to date. I want it to be proper HD, like I get on my PS4, not a low res 1080. Help?
