I have crossfire ATI Radeon hd 5770's. Installed the proprietary driver and decided to install the newest driver from the site. Now there is a huge scaling issue that ATI always does with HDMI connections. It does it on hd tv's and monitors alike.
Also a windows issue, but on the windows catalyst control center there is a slider than lets you change the value of the scaling to 0%. So now I'm stuck with this annoying black bar around my screen even though the resolution is set to 1920x1080 please help
Update: Newer versions of the catalyst driver (like 12.3 and 12.4) include the overscan and under scan scaling to fix the black boxes. It should be located under the display manager sub menu in the Catalyst Control Center. Mine was labeled DTV (probably for Digital TV or something) and it was the last tab (called Adjustments.) By default mine was set to underscan 10%.
