output of ddcutil capabilities for both monitors
SUMMARY
In Plasma 6.0 (Wayland) I was able to control both my monitors brightnesses
over DDC. After updating to Plasma 6.1 the brightness slider only dims my
primary monitor, and leaves both monitors brightness setting unchanged.
Notably my second monitor (Dell U2312HM) was affected by #484037 (
