Simple fix for overscan and Intel graphics cards
With the newer Intel graphics getting so much better, I know there are people having the same issue as me with their HTPC. The Intel software doesn't seem to have overscan correction! And Powerstrip doesn't work either.
I figured this out on an Intel 4600, Windows 7 64-bit, 22.214.171.124.3496 driver. Probably works for others though.
Right-click on desktop, then Graphics options submenu, Custom Resolutions. Select your display (your TV) on the left. Now enter the resolution you want to use (for me it was 1920x1080, 32bit, 30Hz, and the last 2 at default). Click add at the bottom.
Now right-click Graphics properties to go into the normal Intel utility. Click Display. Select your display on the left. Click Customize aspect ratio at the bottom. On the right side, you now have overscan adjustment bars! Correct your overscan and hit Apply. Done.
Please post if this works on your chip. And share across other forums, I'm not bored enough to go post this on all of them.
