- HP Spectre Laptop, running Windows 10 Pro with all the latest updates
- Plugable Triple-Monitor docking station: https://www.amazon.com/Plugable-Charging-Delivery-Specific-Thunderbolt/dp/B01FKTZLBS running the latest DisplayLink drivers
- 2 HP 23' Monitors
- 1 TCL 43" LCD TV
I run the setup with the laptop closed - the two HDMI ports on the Plugable dock go to each of the HP monitors, and the DVI port goes to an HDMI port of Input 2 on the TV. I'm running extended desktop mode.
When I switch the TV away from Input 2 to a different input, Windows 10 still recognizes it as an external display, which is unwanted behavior for several reasons. Clearly, just switching away from the input does not truly disconnect the communication between the TV and Windows.
I'm trying to figure out if there's is a way to accomplish this disconnection, either in the TV settings, in Windows, or via some 3rd party software helper app.
