Desperate Resolution search, just can't get it going / RPi4 via HDMI to TV

    Dear all,

    whatever I do, I don't get it running (I'm a total noob btw.)

    My TV set is the following: https://www.strong.tv/en/products/hd-ready/srt32hb3003

    My machine is the 8GB RPi 4.

    SD card formatted by SD card Formatter on MacOS catalina.

    Latest LE image flashed by official Raspberry Pi Imager.

    Used HDMI port's the one next to the power plug.

    RPi power adapter is the original one.

    With the following settings - after hours of trial - it worked once to get a signal until rebooting (didn't change resolution within Kodi):

    ______________________________________________________________________

    # Set 'force_turbo=1' to disable dynamic overclocking and enable overclocking always.

    force_turbo=0

    # Force HDMI even if unplugged or powered off

    hdmi_force_hotplug=1

    framebuffer_width=1366

    framebuffer_height=768

    # Doesn't sent initial active source message.

    # Avoids bringing CEC (enabled TV) out of standby and channel switch when

    # rebooting.

    hdmi_ignore_cec_init=1

    ______________________________________________________________________

    What didn't work:

    Setting hdmi_group=2 and hdmi_mode=81 (which is 1366x768)

    hdmi_force_hotplug=1

    I'm able to ssh into the machine btw., so it boots up without issues except blank screen / no signal.

    I have no idea and there's, as far as I can google it, very few cases which are close to mine.


    Any help woul be great!

    Thanks in advance :):):)
