No CEC control from GLK-UC2X to Samsung QN75 series TV

Hi Ken / All,

I bought a second GLK-UC2X to use as home theater PC. I have it feeding a new Samsung Smart TV into HDMI 1.

So far, I'm not getting a CEC command from the GLK to the TV. Turning the computer on does not turn on the TV or switch it to the proper input.

All my other devices, like the Bose, Firestick, Chromecast, etc. plugged into the TV automatically switch it on and change inputs, but not the GLK.

Is there a setting in the bios or somewhere that will enable the CEC signals from the GLK to the TV? Would it work better if I used a USB-C video out instead?

Thanks,
