Can you prevent a NUC from automatically changing the TV to HDMI input?

It's a Boxnuc7, if that helps. As soon as I power on the NUC it steals the TV from whatever I am watching. :(

LOL! Welcome to the oh-so-wacky world of Consumer Electronics Control (CEC)...

 

If you disable CEC support in the NUC, it will stop doing this.

 

  1. Use F2 at BIOS POST to enter BIOS Setup (Visual BIOS).
  2. Click on Advanced, then Devices and Peripherals and then on Onboard Devices.
  3. In the Legacy Device Configuration window on the right, uncheck HDMI CEC Control.
  4. Remember to save your configuration changes when exiting from Visual BIOS.

 

Hope this helps,
