Im getting a split clone screen

[xgenimx]

For months or maybe a year i never had any problems, i had some settings set up that helped me run it better but never game any trouble so i never touched them, but out of nowhere i started getting split screens in everysingle game. After this i've been trying with a lot of settings but none seem to fix it.
