For some reason all my monitor is showing is a white screen... I don't know what's wrong with it. I tried the monitor on a different computer, and it did the same thing so I know the problem is the monitor. Any idea of why it would be doing this?

I'm not saying it definitely is, but when my last screen died on me, it went white.
You'd assume it goes black, but white was indeed the colour of choice for my dead screen! (they still receive power but don't process the information sent to them)

Since you've tried it on another system, it's pretty likely though.
Sorry.

Yea that seems to be the problem :-/ I hope the warranty is still good on this thing.
