Hello

I have a mini PC that I have running Anthias. Got it doing what I want. Mostly.

I would like to be able to use the 3 onboard HDMI to duplicate the output to 3 different monitors.

How can this be accomplished?

I’m using a debian 12 based machine that has Anthias loaded on it.

Thank you.

@AlBoudreau, let me check this one. Anthias currently uses framebuffer for display. I’m currently working on changes where X11 will be used instead. Hopefully, the switch could help support custom display settings like duplication.

I’ll keep you posted.

I appreciate that. Currently when you have 2 displays connected (with the same resolution), one display stays static while the other rolls through the files.
