I got this fat Sharp CRT some time ago and Im essentially using it as a 3rd monitor but trying to play Emulators on it as an actual CRT. Thing is, when I actually drag the CRT over to it it doesnt adjust the emulator box to the screen like it does on any normal monitor, and it basically cuts off the bottom. And if I try to do fullscreen on it, it compresses it like this with giant black bars on both sides. Is there a way to fix it?
