Hi. I recently installed LibreELEC 10 on a zero 2w (because the 11 installer prompted me an error everytime I booted it) and it works fine in any modern TV, but I have an old flat screen from ten years ago in which I don't get any output when I connect it to my pi. It's specially weird because I used to run Raspberry OS on the same device and the screen worked just fine after adding the "hdmi_force_hotplug" flag. Already tried adding:
hdmi_ignore_cec_init=1
hdmi_safe=1
config_hdmi_boost=4
hdmi_force_hotplug=1
hdmi_group=2
To the config file and that only showed the color splash screen and nothing else, not even the LibreELEC logo. I've read I have to do something with the cmdline file but I have no idea how to do it.
So any ideas to work around this?
