@jell no. You can change video mode - and if your TV can switch based on that, then maybe. But the rpi can't specifically control various TV model settings.

Hello fellows. I would like to say thanks! The cec-utils package is pretty handy. The udev rules are perfect! The only addition I've made on my arcade build was adding a turn off monitor.sh script in RetroPie Menu. #!/bin/bash # turn off monitor.sh ################# # Actually puts the monitor on stand by mode. echo standby 0 | cec-utils -s -d 1

I never tried that kind of remotes, but it should work. Did you configured the remote like explained here ? https://support.myharmony.com/en-in/harmony-experience-with-kodi or here ? http://wiki.openelec.tv/index.php/Config_harmony
