Bug ID: 417543
Summary: Refresh rate changes sometimes after switching monitor
inputs
Product: KScreen
Version: 5.18.0
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: common
Assignee: kscreen-bugs-n...@kde.org
Reporter: rokups...@gmail.com
Target Milestone: ---
I have two monitors: 1440p 144hz with freesync and 1080p 60hz. 144hz monitor
resets it's refresh rate to 60hz quite often, but this is not 100%
reproducible. I use monitor input switching a lot (/dev/i2c-*, ddcutil). This
makes me think that merely switching monitor input source is enough to trigger
this issue, as switching back to input driven by linux would sometimes
initialize it at 60hz and not 144hz.
Important detail: Default supported freesync range is 35-90hz on this screen. I
use modded edid firmware to change this range to 57-144hz. This works perfectly
fine.
It would be great if monitor could keep refresh rate configured in display
settings instead of sometimes switching to lower one for some reason.
