Hi,
Thank you for the great app, but a have an issue with the LG IPS277-L display. The Dell P2715Q display connected via DisplayPort works perfectly, but I can't control the brightness of the LG one (connected via HDMI). Is there anything I can do to make that one work?

Hi @techo91,

As this app depends on kfix/ddcctl for controlling external display, it may simply be that the LG IPS277-L does not support DDC.

You should ask your question there for support,
Have a nice day

According to LG It does. That is the reason I asked. Thank you.
