"Resolution is 1280 x 1024."
Either you have Windows scaling on or it's just because that's a really low resolution
Elaborate? What should the resolution be? 1920 x 1024 ? 2440 x 1440 ( I believe)? Or even 4K? "a big fkn tv" doesn't mean you will be 4k resolution or something
Edit: On windows, right click desktop click "screen resolution" and modify the resolution from there.
