I setup the TCL as an extended monitor, but every 15 minutes or so, my PC acts as if another monitor has been plugged in/turned on (pauses and recalibrates). It does this even when the TV is turned off. I've already turned off HDMI (CEC) and its still doing it. The only advice I find online is to turn off HDMI (CEC) and that's not working.

Thanks in advance.
