All folks with AMD cards should redo the test with a small tweak noted in the first post.

MS-DOS pointed out that AND driver dithers the output when it outputs more than 8bit, so you may actually get dithered 8bit which looks like 10bit on ANY panel.
Nevciriel pointed that he gets a smooth ramp even with a known not 10bit panel, and MS-DOS pointed that his 6-bit DELL U2212HM is also smooth...
So all you AMD folks need to do a little registry work to test actual 10bit output and not dithered 8bit by AMD driver.
