Lines are blacking out info I need to see

[COLLECTABLE99]

I use my monitors for work, and the screens are very pixilated and spotty like little dots and the colors look strange. but the worse part is that information I need to read has black lines running through it. sometimes it is colored and I have to keep clicking on the size% window to be able to read items, but sometimes I cant read them at all, they stay colored or blacked out. Please help.

Thanks,
