Or could have been an NVidia driver bug that caused problems when modes for both 4:2:2 and 4:2:0 were available, hard to say. Anyways, seems like if we can get the driver to try 4:2:0 (possibly ignoring the monitor to do so) then it should work at 60 Hz.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
