Well, I have no idea either.
Next time this happens, try 96 dpi and 32 bits colors. The screen resolution you are using could potentially be a problem. I’m not sure if it really is a problem in this case, but it could be.
Some screens MUST use a specific screen resolution and screen frequency. This may sometimes influence how you see what is being displayed (correctly or not). I have no idea if this is your case.
