does this work? i have one of these but the one button interface is frustratingly far from my desk chair

@h3rb I missed seeing this for a year, but yes, this worked great for me for the couple years I used it (before upgrading to a 55" OLED TV also controlled by RS232).

Hello everybody,

So I've made a GitHub repo to make it accessible by everybody : https://github.com/YooUp/RS232-Monitor-Commands
