Has anyone managed to get an HDMI screen working at the same time as the official raspbery pi screen?
The 7inch touch screen is running via the screen ribbon cable so the HDMI port is free. I've connected that to an external screen and it appears to be sending out a blank signal.
I'm looking to mirror the screen to a second display which I can see when driving to keep an eye on charge rates.
I've played a bit with frame buffers but not got it working - can anyone point me in the right direction?
