I installed a 6450 yesterday and plugged my projector in via HDMI. There's a big 4 inch slanted gap on the right side that I can't fix with overscan. Moving the overscan slider far enough to cover it means I lose big chunks of the other sides of the desktop and video.
The projector is aligned perfectly, the only input I have a problem with is the video card (xbox, wd tv live, Dish, uverse, all are perfectly aligned). It looks like ATI removed the ability to adjust screen position. You used to be able to grab the screen and move it in CCC. Is that gone? Why? How do I fix this problem?
