I tried that and things got even more weird!
- I tried an independent video player (Fantec R2650). It *did* deliver a FHD picture on my monitor (previous to connecting to my TV), it *did* deliver a picture on my TV (on different HDMI ports of the TV), it *did* deliver a picture on my monitor (after connecting to my TV). So my TV has several HDMI inputs, they're working fine (at least with the fantec) and they don't kill the HDMI outputs.
- I tried Raspbian on the Pi4 and got *no* picture.
- I tried additionally setting these options:
hdmi_safe:0=1
hdmi_group:0=1
hdmi_mode:0=1
hdmi_force_mode:0=1
but *no* picture as well!
- The TV recognizes there is "something" on the HDMI port because it offers Simplink (the LG name for HDMI-CEC) to activate, it does however take remarkably long and does not yield a picture.

Now I'm completely stunned as you may think, the culprit is none of them! What else can I try to get a picture or to find the reason for the problems that I'm facing?
