We are now using 12bpc though whereas in the past we would have used 8bpc. So that could explain the change in behaviour. If the signal quality is marginal it's possible the problem would only manifest in the modes that require the highest bandwidth, which seems to be the case here. Are you using a HDMI<->HDMI, DVI<->DVI or HDMI<->DVI cable? Any extra dongles/adaptors? Trying to eliminate extra dongles and whatnot might help, or the cable itself might not be of sufficiently high quality so trying another cable might help. Also if you're using the HDMI connector on the projector it might make sense to try out the DVI connection instead (AFAICS that projector should have both?). In theory it should not report 12bpc capability over DVI which would force us to pick 8bpc.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
