CEC Function for Extend or other products

For customers who need to display content in 4K because of the display size, the video signal has to be routed directly to the display.

In this configuration, the display cannot be switched on or off via the system, as CEC control is not available. Hotplug detection is also not a viable option, because the extender remains permanently detected by the display. As a result, the display does not recognize whether an active source is actually present or not.
