There is sadly no hdmi CEC support on Most GPUs for pcs. So when you want your tv to turn on and off with your pc it is only possible with the tv being reachable from your pc via ip.
I believe LG doesn’t advertise such an api via Bluetooth
- 05 27d agoHDMI breakout and a esp32 module flashed with esphome is another option. The tv most likely doesn’t care that the port that sent on/off command is not the same port the video signal is coming from..
- Asmod4n 27d agoThe tv does care which port it came from, since it automatically switches to the one which made the request. One could build a IR emitter but you need soldering skills for that or buy a usb one which cost north of 30€ + shipping.

- account42 27d agoFor a 4K120Hz TV I'd be worried about this adding signal integrity issues - "all versions of HDMI®, including HDMI® 2.0a" doesn't inspire confidence.
- FireBeyond 26d agoMy understanding is that CEC can be received on any alive interface, not just the active.
- colingauvin 26d agoYes but you will lose 120 FPS/VRR. So for high end TVs not really ideal.
