How to connect HDMI monitor to my AutoPi TMU

Troubleshooting
#1

I need to connect my HDMI monitor to the autopi TMU unit. I want to use the monitor as a dashboard display showing the autopi dashboard.
I tried to setup iceweasel with xorg/xinit and xserver setup to login as user screen but nothing gets displayed on the HDMI after boot up. It appears the HDMI is shut down. And I can’t connect through ssh to the TMU.

Don’t have an AutoPi here, but as it uses a Raspberry Pi, I think this solution should apply.

Considering you are using a Linux distribution, run the following with the device SD card connected to your host PC: (If you aren’t using Linux, maybe you could access this file with some tool, or even directly by Windows)

$ sudo mount /dev/sdX1 /mnt - Where X stands for the SD Card device identifier
$ cd /mnt
$ vim (or nano) /mnt/config.txt

Editing this “config.txt” file, you should be able to enable HDMI if it’s not. For that, check those lines:

## hdmi_safe
##     Use "safe mode" settings to try to boot with maximum hdmi compatibility.
