Bug ID: 445757
Summary: Confusing display of resolution of scaled screens in
Wayland
Product: KScreen
Version: 5.23.2
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: common
Assignee: kscreen-bugs-n...@kde.org
Reporter: philipp.reichm...@gmail.com
Target Milestone: ---
SUMMARY
The Display Settings KCM will show the resolution of the screen in the scaled
coordinate system of the Wayland compositor. This means that it will show a
value that does not correspond to the physical resolution of the monitor, but
with the screen scale factor applied. This can be confusing to new users,
because they are used to think in terms of monitor resolutions, not screen
coordinates.
It would be preferable to show both the resolution of the scaled coordinate
system, as well as the physical resolution of the monitor in the same place.
STEPS TO REPRODUCE
1. On Wayland, open the Display Settings KCM and set scaling for a display to a
value other than 100%.
2. Look at the resolution shown inside the screen icon in the top panel.
OBSERVED RESULT
E.g. for a 4K/3840x2160 screen at 200% scaling, the screen icon will show
"(1920x1080)", even though the physical resolution is still 3840x2160. The KCM
will show the physical resolution 3840x2160 in the dropdown box under
"Resolution", but it is confusing to new users - it was to me.
EXPECTED RESULT
The screen icon should show a more descriptive text that includes the scale
factor, e.g.:
1920x1080
(3840x2160 @ 200%)
