Yeah, upon further inspection, I found that the OS isn't the problem; it actually just is my shity TV.
This person had the exact same problem I do (same TV), that of course was never fixed:
https://www.reddit.com/r/24hoursupport/ ... op_when_i/I was initially being an idiot and comparing the results of my GameCube on my CRT to my LCD, but I wasn't thinking about how the CRT wouldn't display the whole image either, lol. I finally figured out it was my TV's fault by using my Wii U and comparing the screen on the Gamepad to the TV. I had never noticed it before because there's nothing essential that far on the sides of the screen.
I thought I'd go on Emerson's website and download new firmware for it, but it just displays "page not found."
