Hmm. Yeah, looks like the DVI EDID is corrupted in the exact same way. We've not had reports of other corrupted EDIDs on these display so I'm leaning towards this being just some random EDID corruption in your particular display. You would either need to fix the EDID in the display via i2c (often there's some kind of service menu available by which you can toggle write protection of the EEPROM) via i2c. Or you need to use the firmware edid loader to override the EDID, which would involve something like putting the fixed EDID into /lib/firmware (or the initramfs if you load i915 from there) and pass the drm.edid_firmware=HDMI-A-1:fixed.edid option to the kernel. I'll attach the fixed EDIDs to the bug...</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 assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
