So I have acquired a Screeneo U4. I can play files from a USB stick via the built in VLC player (which was a nice surprise).
However, I have a Watch ONN chromecast box which is plugged into the wall and is configured. When I fire up the Screeneo U4, I get the NO SIGNAL screen.
I also get the same thing when I plug it into my MacBook Pro 14" 2021. NO SIGNAL with the projector; when I go to the Monitors setting via the top of the screen, it flashes on and off but I am unable to choose it as a source.
Is there a Jedi Mind Trick to getting these devices to work via HDMI? I’d really like to use this to replace the TV so I can watch streaming on it…
