I have a radeon R9 270X, latest drivers, latest CCC. I have 1 TV (1920x1080) hooked up with HDMI, 1 monitor (1440x900) hooked up by DVI, and a second TV (1920x1080) hooked up with an active adapter(display to HDMI). My issue is that the second TV gets overscanned when it's on the 1920x1080, which is its native resolution, but when I try to underscan the display the option is grayed out in CCC. It's not grayed out for the other TV and it worked fine before switching to the active adapter. Is there a way to fix this?
