@Axolotl1@gaygeek.social I think you're using Windows OS? I'm not very windows-y. From: https://superuser.com/questions/916538/how-to-use-cec-from-windows " First check if your graphics card (hardware) supports HDMI CEC. Then also the drivers must support it. But according to this review, very few cards have CEC support. For PCs without CEC support, there exists various products which add CEC support. They connect between the PC and TV on HDMI cable plus via USB to PC. The software sends CEC commands to adapter via USB. One example of such product is: USB HDMI CEC adapter from Pulse-eight. " So it seems from the above that unless your video card is going to be one of those that have CEC support, you are out of luck on using the Consumer Electronics Control protocol to remote control your TV over HDMI. I could set you up with an infrared gadget that connects to your PC and lets your PC turn the TV on, but maybe that's no better than just using the remote?
