Description
Custom EDID to run the Dell Alienware AW3423DWF at 165Hz and 157Hz while using 10-bit color.
The 157 is CVT-RB2, while 165hz uses timings from this reddit post
Troubleshooting:
Flickering when using VRR.
Experienced with AMD 7900XTX GPU running Mesa drivers on both 157hz and 165hz.
Suspected cause: IIRC the GPU uses vblank to sync refresh rate. It's ~10x shorter with these timings.
Workaround: Disable "Adaptive Sync" in system settings. - There's a high enough refresh rate and low enough pixel response time that screen tearing is unnoticeable with this monitor, in my experience.
Installation Instructions
Atomic Desktops:
- Click the right release below, then copy the repository info to a file in /etc/yum.repos.d/
sudo rpm-ostree install dwf-edidsudo rpm-ostree initramfs --enable --arg=--install --arg=/lib/firmware/edid/dwf-edid.binsudo rpm-ostree kargs --append-if-missing "drm.edid_firmware=edid/dwf-edid.bin"systemctl reboot
I don't use standard Fedora Workspace anymore, but it should be similar
- Enable COPR repo
dnf install dwf-edid- Add file to initramfs. (I don't know this part)
- Add kernel argument
drm.edid_firmware=edid/dwf-edid.bin(also don't know this part) - Reboot
