I was going to give this a much more specific topic title, but thought maybe starting a “catch all” thread for Khadas VIM2/3 users might be a better idea for the long run.
I know several people here are using the VIM3, so I have a question that is not directly RealDash, but it is indeed related. I am just now getting this thing up and going, running Android, straight out of the box, with no modifications. It will come up and run fine with a full size monitor. I also have two different brands of 12.3" ultrawide 1920x720 LCD panels, each running a different HDMI board. When I plug the VIM3 into these, the HDMI driver boards turn on, seeing a signal. Neither panel will display a picture. Moving back to a full size monitor, I manually set the display resolution really low, and change to 50Hz refresh, and still no picture on the LCD. Does anyone have any ideas on this? Thanks!
