Here's my problem:

 

I have 3 monitors connected to my Mac Pro (specs listed below).  Whenever I restart in Windows 7 (drivers updated, installed monitor control panel, Mac drivers updated) one of my monitors always gets screwed up with the resolution.  I have 2 22" monitors and 1 28" monitor.  The one that always gets messed up is the 22" screen with a resolution at 1680x1080.  Windows 7 detects the resolution being about 600x800 or something.  To fix this, I have to unplug the mini dvi port from the computer and simply plug it back in.  The monitor instantly goes back to full resolution and then I have no issues until I restart again.

 

I don't seem to have issues if I leave 1 22" monitor and the other 28" monitor plugged in.  This only happens when I have all 3 connected.

 

I've tried numerous times to update drivers and download the graphic card control panels, but none of it seems to help.

 


Would anyone have a clue as to why this happen?
