I failed at editing the file first because it was a 0 byte file (didn't had my TV connected lol!) So. I followed this video https://www.youtube.com/watch?v=tYYMiX7dlak And basically did the following in my debian sid partition (I will describe it for anyone interested): To find my TV edid $ find /sys/devices/pci*/ -name edid Grab/copy the desired edid file to my home folder $ cp /sys/devices/pci0000:00/0000:00:08.1/0000:05:00.0/drm/card0/card0-HDMI-A-1/edid ~/edid.bin Then edited that file with wxedid to change the following: SPF: Supported features = vsig_format to 0b00 CHD: CEA-861 header = YCbCr 4:2:2 to 0 CHD: CEA-861 header = YCbCr 4:4:4 to 0 VSD: Vendor Specific Data Block = DC_Y444 to 0 Then before saving the file I clicked Options > Recalc checksum (otherwise the system will not use your edited edid!), after that I did saved the file, and copied that new modified edid file to /lib/firmware/edid/edid.bin To use the new edid, I added 'drm_kms_helper.edid_firmware=HDMI-A-1:edid/edid.bin' to /etc/default/grub (to the line GRUB_CMDLINE_LINUX="foo") updated initramfs with 'sudo update-initramfs -u' and then updated grub as well with 'sudo update-grub'. Note: I compiled the latest wxedid from sourceforge, and, 'options > recalc checksum' option is MISSING at least for me. That's why the process was failing for me. Luckily for me debian has a wxedid in their repo that has the recalc checksum option. Now... bit of work ain't it? I don't know if this happens because of my TV, I haven't tried with other monitors/televisions. But a bit of improvement in the matter would be GREAT. -- You may reply to this email to add a comment.
