@BillyCallahan Based on what @Dom1n1c said: My screen does not show the brand when it wakes up from standby, sometimes you might be able to find an option in the internal menu of the screen.

As for triggering the tvservice commands, there are modules that do it automatically based on a PIR-Sensor or via a webcam. They switch on the screen when someone is moving in front of the mirror, and switch it off after a fixed time (e.g. 60 seconds).
