Installed my fancy new Radeon 9200 in XP.  When XP was driving the monitor (before I installed the driver) the picture filled the screen.  After the driver I have a unused black box around the displayed picture. I tried adjusting the resolution and the "size" in the Advanced tab of the display driver but it still doesn't fit the screen fully.  I even updated the driver using the newest from the ATI site (which included rotation, cool), but to no avail.  Any ideas?
