I would like to disable the HDMI cec, because when the raspberry pi 4 turns on, it always turns on the tv together…

hdmi\_ignore\_cec\_init=1

what did you already try? And what was the difference the to the solution now?
was it `hdmi_ignore_cec=1` before and `hdmi_ignore_cec_init=1` now?

yes I tried the command hdmi\_ignore\_cec=1 and it didn’t work and then I saw this command hdmi\_ignore\_cec\_init=1 on this site and tried it, I don’t know why it worked, it was luck

Looks like it is needed to even disable the initial CEC request. However it would expect it is already done by disabling the whole CEC function. Something to keep in mind. 🙄
