hdmi 2.1

HDMI and DisplayPort are both digital video interfaces used to connect devices like computers and monitors. While both can transmit audio and video, DisplayPort generally offers higher bandwidth, allowing for higher resolutions and refresh rates, while HDMI is more prevalent on TVs and gaming consoles.

I think it might be a bandwidth issue since it works if I change my color space to Ycbcr422 as I mentioned

edid-decode /sys/devices/pciXXXX:XX/XXXX:XX:XX.X/drm/cardX/cardX-PORTNAME-NUM/edid

Replace the Xs and the PORTNAME-NUM with the relevant value for your system - you can find all the possible paths by running:

ls /sys/devices///drm///edid

#

is your reso correct on 1920*1080 ??

#

give me a sec

#

Create the EDID directory if it doesn’t exist:

sudo mkdir -p /lib/firmware/edid/

Copy your exported .bin files into this directory:

sudo cp path/to/your/DP1_1920x1080_144Hz.bin /lib/firmware/edid/
sudo cp path/to/your/HDMI1_1920x1080_144Hz.bin /lib/firmware/edid/

#

no, run after replace the Xs and PORTNAME withthe values of YOUR system

#

after that, do following

#

Edit the kernel command line configuration file:

sudo nano /etc/kernel/cmdline

Remove any existing video= parameters related to your monitors if you tried that method before.
Add the drm.edid_firmware= parameter to specify your custom EDID files for each monitor. Separate multiple monitor entries with a comma. Ensure the output names (DP-1, etc.) match your system. Example:

root=PARTUUID=YOUR_ROOT_PARTUUID rw quiet drm.edid_firmware=DP-1:edid/DP1_1920x1080_144z.bin,HDMI-A-1:edid/HDMI1_1920x1080_144Hz.bin,DVI-D-1:
(Replace YOUR_ROOT_PARTUUID, quiet and other existing parameters as per your original setup. Ensure the filenames match what you copied.)

Save the file and exit the editor.

#

Run mkinitcpio to regenerate your initramfs. On Arch Linux, this process (when standard kernel-install hooks are in place) also updates your EFI boot entries with the new kernel command line from /etc/kernel/cmdline.

sudo mkinitcpio -P

Note: You do not need to add the EDID files to the FILES array in /etc/mkinitcpio.conf. The NVIDIA driver will load them from /usr/lib/firmware/edid/ when it initializes.

#

sudo reboot

or manually, doesn’t matter.
