Enforce HDMI with 1920×1080 on Raspberry Pi 3 and Raspbian

Written by  on August 6, 2017 

Ok, we have a brand new RPi, an SD-card with the latest Raspbian, some brand new monitor with HDMI-input only.
Everything is set up, the power plugged in, one LED shines, another one, then “no signal” on the monitor.
0. SSH-access not possible due to the fact that because of those botnet-takeovers of RPi in the past the default access was disabled for fresh images.
1. Wifi with VNC also impossible, because how to set the Wifi-credentials if you can’t see something?
2. VGA not possible due to hardware-limitations.
Great 🙂 I love when soft-/hardware does not work out of the box :’)

After a while of tinkering I remembered that I had to enforce the HDMI-ouput on the first RPi (the one for the catcam).
Can be set inside /boot/config.txt (leafpad is the current default editor on Raspbian).
