Hello! I'm wondering. is it true that the bigger the display is the bigger the memory required for gaming? I ask this because someone told me if I'm gaming with a 22" ws monitor I should consider a video card with higher memory, and right now I'm wondering why I can't run games on my 50" Plasma TV, every game I load up takes me back to the desktop and with my 22" monitor that doesn't happen, I have a 7800GS with 256MB. so, is it true? or memory has nothing to do with that issue?
