HDMI

Some devices support HDMI output to an external display.

To set the output resolution (eg to 1280x720) automatically on boot on a build using the sway compositor:

Create autostart script:

mkdir /storage/.config/autostart
nano /storage/.config/autostart/090-sway-hdmi-resolution

In script (set a proper "output..." string to match your modifications):

#!/bin/bash
echo "output HDMI-A-1 resolution 1280x720" >> /storage/.config/sway/config

Make the script executable:

chmod +x /storage/.config/autostart/090-sway-hdmi-resolution
