I am experiencing a weird problem with my new monitor, I tried connecting it using HDMI but the image was displayed on a part of the usable screen. When I tried to decrease the resolution to 1680x1050, the whole display was used
As you can see, not all the display is used when set to 1080p
When switching to 1680x1050 however, all the display area is used
As an act of desperation, I tried connecting the monitor using VGA (Yuck!) and the monitor used every available pixel even when set to 1080p.
One more thing, I noticed that when the monitor is connected to HDMI, 1080p resolution appears in "HDTV" category in Catalyst but that doesn't happen when the monitor is connected to the VGA port. That lead me to think that the issue might be caused by the driver
