Hi group,

does the Ultibo RTL offer provisions for setting/changing HDMI display brightness?

The Pi firmware doesn't expose any options for this so there isn't anything directly supported in Ultibo yet, however this thread offers some possible solutions that might lead to an answer.

Naturally anything that can be done via software in Linux is also possible without Linux, it's just a matter of knowing what signals need to be sent to what device.

Thanks Garry,

that link provided insights about display brightness settings not being part of the HDMI spec and hence being very hardware specific. I might not be up to this challenge but at least I now have a better understanding.
