Yes, Korbyt Digital Adapter (KDA) Media Player Devices do support sending screen control commands to the actual screen or TV
This can be limited by screen manufacturer and compatibility.
In a Player’s Settings in the Korbyt Content Management System (CMS) there is a section for Screen Control.
Here you can turn on screen control and configure it for your screen and the command you want to send
For more details on how to edit the settings of a Media Player in Korbyt see Viewing and Editing Player Details
If the screen you are hoping to control is not a listed make/model you can configure additional ones in your Tenant Settings > Screen Control
To configure additional displays you will have to know the HEX / RS232 / IR codes for the model you are trying to control
