This isn't really important, but would be nice to know. I'm planning on using it for my new pc, and it'll be running off of a gtx280, and I'll be using my PS3 as well. But what I'm interested in, is can I run my current system to it as well, with a FX5500? I'm sure it won't power the whole screen, but can I get it setup with a black border? And how does the monitor switch between the different inputs, is there just a button?
