OpenMarine

Apologies if this is requested already.

In my setup and I assume most non-headless installs the main power user is the monitor. It would be great if there was a setting to put the monitor into sleep/standby mode (way less power usage) after a user set number of minutes then wake after a key press.

Our general usage would have one of the crew check the chart plotter whenever they pass the nav station say every 5 or ten mins possibly even longer if in clear water. The rest of the time the monitor would be drawing a lot less power.

The monitor can be powered on and off manually, but if this is an easy feature to add it would be a lot more elegant.

try this because its a raspberry pi thing not a op thing. its not an easy feature to add.

in the terminal
sudo nano /boot/config.txt

add this line to the file somewhere.

hdmi_blanking=1

ctrl x then y and enter..
sudo reboot

let me know if that works for you
