Project ID: 128580

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:

  1. Click the right release below, then copy the repository info to a file in /etc/yum.repos.d/
  2. sudo rpm-ostree install dwf-edid
  3. sudo rpm-ostree initramfs --enable --arg=--install --arg=/lib/firmware/edid/dwf-edid.bin
  4. sudo rpm-ostree kargs --append-if-missing "drm.edid_firmware=edid/dwf-edid.bin"
  5. systemctl reboot

I don't use standard Fedora Workspace anymore, but it should be similar

  1. Enable COPR repo
  2. dnf install dwf-edid
  3. Add file to initramfs. (I don't know this part)
  4. Add kernel argument drm.edid_firmware=edid/dwf-edid.bin (also don't know this part)
  5. Reboot
