VRR setups
This page collects test results for Variable Refresh Rate (VRR) aka. adaptive sync setups seen in the wild.
To add an entry:
- Enable VRR on your display(s) via
output <name> adaptive_sync on(seesway-output(5)for details) - Make sure VRR is enabled with
swaymsg -t get_outputs | jq '.[] | pick(.name, .adaptive_sync_status)' - 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")
