Does not have to be able to do both, I already have a PC screen - Samsung Syncmaster P2250 21.5 inch LCD screen.
But I am buying a PS3 soon, and I do not own a TV currently. My father has a 42 inch LED TV but I do not really want to resort to using it because I'm 19 years old and don't want to rely on his TV schedule for when I can play.
We do have an old spare TV, I used it back in 2007 to play PS2. I know it can run a PS3, but not HD. Which kind of defeats the purpose, right?
Moral of the story, recommend me a decent TV please for under R3500.
