I have a 20m fibre optic cable, these things are great. Thinner than a standard cable. They are unidirectional, but mine has a dedicated copper line for CEC. 4k 120hz is no problem.
I also have a Pulse Eight CEC adapter in the chain, but I had to swap its included HDMI cable for full bandwidth.
Since I've switched to Linux I haven't had a chance to set up the software side for CEC though, does anyone happen to have recommendations?
- chhs 3mo agoI bought the same adapter and use it with Bazzite, which has a `toggle-cec-sleep` you can run that just set it up. Now when I press a button on my keyboard, the PC starts up and the TV turns on. It's magical. https://docs.bazzite.gg/Installing_and_Managing_Software/Bazzite_Portal/ https://docs.bazzite.gg/Installing_and_Managing_Software/Baz...

- Tajnymag 3mo agoWhat I've heard, for some reason, you can get CEC and working when you use a displayport -> hdmi adapter with the right chipset inside. So theoretically, get the right adapter, plug it on the side of the computer and you might actually get CEC signal decoded as a new kernel device.
