Here are the updates: - I was able to see the issue with the attached library too, on selected mode. - The display never fails when using the analyzer. It only fails using real monitor. - Scrambling and clock high ratio is getting enabled/set/disabled properly. - Bootup and modeset dmesg logs attached. I think this is a fault with monitor, which is not able to handle this mode at 12BPC (Also, This mode is a non-CEA modes, so not a standard one too)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
