To add an entry:
- Make sure VRR is enabled with
swaymsg -t get_outputs(look for "Adaptive sync") - Play with your desktop for a while, try various apps (text editing, web browsing, video, games)
- Also play with the backlight level
- To get the VRR range, you can use:
cat /sys/class/drm/card0-DP-1/edid | edid-decode(look for "Display Range Limits")
