A big-screen PC sounds like a great idea. But a big-screen PC is not what it may seem. That's the main problem with most of these so-called PC entertainment centers. Instead of getting a PC that can function as an all-around personal computer and family entertainment device, you get an expensive family entertainment device, period. Both those functions require a sharp screen and a lot of resolution.
Sharpness is easy to understand.
Anything displayed on the screen should be clear. All outlines should be cleanly etched and not fuzzy. Resolution is harder to understand. It's the way we describe how much detail we can see in something. That's all I could see.
