I recently got my HDMI cord in the mail. Before, I was using DVI. I have an ATI XFX 5850 and an ASUS 23.6'' monitor. They are both awesome. When I was using DVI the picture filled the entire monitor. Now that I am using the HDMI cord the picture is smaller, there is about an inch of black on all sides. I don't know how to fix this. Is this just the sacrifice of using true HD 1080p? Thanks!
