# Modify EDID, so my screens work at 61Hz
|
|
Trying to fix some what high power draw of RX 7900XT(to make its memory run cooler).
|
|
|
|
|
|
|
|
|
|
## XOrg
|
|
Put below config in `/etc/X11/xorg.conf.d/09-displays.conf`(also attached as file in /X11/09-displays.conf).
|
|
```
|
|
Section "Monitor"
|
|
Identifier "DisplayPort-0"
|
|
Modeline "1200p_61" 196.53 1920 2048 2256 2592 1200 1201 1204 1243 -HSync +Vsync
|
|
Option "PreferredMode" "1200p_61"
|
|
EndSection
|
|
|
|
Section "Monitor"
|
|
Identifier "DisplayPort-1"
|
|
Modeline "1440p_61" 317.24 2560 2744 3024 3488 1440 1441 1444 1491 -HSync +Vsync
|
|
Option "PreferredMode" "1440p_61"
|
|
EndSection
|
|
|
|
Section "Monitor"
|
|
Identifier "DisplayPort-2"
|
|
Modeline "1200p_61" 196.53 1920 2048 2256 2592 1200 1201 1204 1243 -HSync +Vsync
|
|
Option "PreferredMode" "1200p_61"
|
|
EndSection
|
|
```
|
|
Then restart X session and from system settings set new resolution.
|
|
|
|
|
|
|
|
## Wayland(Gnome/KDE)
|
|
In this case, there are 2 options. First is to pass `video` kernel parameter(but it does not work for me) and other is to modify EDID so it contains addidional resolution data.
