I have tried connecting several monitors with HDMI inputs to to my Cerbo GX, I swapped the HDMI cables but still no sign of a signal. Has anyone had a similar issue?
Other than the HDMI output everything else appears to be functioning fine on the Cerbo.
@Tony If you search the forum you will find a number of threads on the topic. It is designed for the GX Touch devices and unsupported on anything else. The cable carries touch screen input signals, which may not be compatible with your tv etc. There are mixed results out there so maybe do a quick search on cerbo hdmi ;)
I have read several threads on here and the only thing you loose is the touch screen functions. The HDMI should output the video signal irrespective of lack of input. I appreciate what you are saying but there should still be a video output. I have checked the aspect ratio and resolution and these are set up correctly.
Moved the original post to modifications. Will close the duplicate.
If you just connect it, on the fly, then it doesn't work.
I have the impression that at boot time the system checks for monitor presence and acts accordingly. Or vice-versa, I don't know...
I've also had this problem with a 7" display and after I rebooted the Cerbo, after a while, after boot, the monitor started to work.
The monitor is this one: https://www.aliexpress.com/item/1005003539330174.html
Thanks for your help, I followed your instructions and it's working now working.
