No CEC when Raspi starts without TV

Hi,

i tried LibreELEC on my RaspiPi3. After adding this to the config.txt, LE works even the Raspi was started at first

hdmi_force_hotplug=1
disable_overscan=1

but in this case cec doesn't work. normally after booting there is a message that pulse-eight cec adapter is connected and i can control librelec with the tv's remote control.

i can't find any option here RPiconfig - eLinux.org to fix the cec problem. is there any solution for that?

Edit:
it happens something strange. i've started the pi, then started the tv. i did nothing with the devices. after dimming the display i pressed the cursor-up key and the tv jumps from hdmi 2 input (where the pi is plugged on) to hdmi 1. it seems that now the pi controls the tv and not the tv the pi. maybe other keys also work, cursor-up is teh only key i've testet.

There is only one HDMI Port on the Pi.

OK, this works.

But what is the difference between HDMI 1 and HDMI 2 at the TV? They are doing the same or not?

OK. It works with the first HDMI port.
