I am on i3 with my Dell XPS 13 9360. I have a THunderbolt3-to-HDMI Adapter from pluggable and a monitor and a cube mini projector.
My Problem is, that when I connect the cube mini projector to my adapter and enable it via xrandr, I get projected my screen with rgb-errors, like I can see my screen, but everything is destroyed with rgb- errors, I mean the whole screen is broken with these colors, I really can't see much on it.
The funny thing is, when I connect the projector to my docking station, it works fine, so this must be a problem with the thunderbolt3-hdmi adapter.
Additionally, to fix this issue, I need to unplug the projector from the adapter, plugin my monitor, plug out my monitor and plugin again the projector, now the rgb-errors are away. STRANGE!!!
I would be very happy if you can tell me where I can find information, e.g. which log files could be useful to you? Also, if you know a solution, please don't be restrained to tell me.
