Bug ID: 512916
Summary: After waking from suspend, 1080p monitor is set to
480p
Classification: I don't know
Product: kde
Version First unspecified
Reported In:
Platform: EndeavourOS
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

Target Milestone: ---
SUMMARY
I have a 1080p 144hz MSI monitor. Sometimes (but not always), when I wake my
computer after putting it into suspend, it will be set to 480p. The system
settings app does not recognize it as a 1080p monitor, and it cannot be set to
1080p again. Rebooting my computer fixes the issue, and turning my monitor off
and back on again also fixes the issue. It appears that this bug only occurs
after a few hours of the system being suspended, such as after returning home
from work or after waking up in the morning. Simply suspending the system and
then immediately turning it back on does not reproduce the bug.
STEPS TO REPRODUCE
1. Suspend system
2. Wait for roughly 8 hours
3. Press power button to turn computer back on
OBSERVED RESULT
The monitor is set to 480p and is no longer recognized as a 1080p monitor by
KDE System Settings.
EXPECTED RESULT
The monitor should be set to 1080p and recognized as such by the System
Settings app.
