Hi all,
I have been using rpi3b with these options for a while on my SDTV and it worked beautifully.
Tried to update to rpi4 - no luck. It displays correct resolution for rainbow boot screen but librelec forces 1920x1080@60hz for some reason.
I've attached config.txt (form rpi4, but I tried the same with latest libreelec on rpi3b and it works fine)
Is librelec overriding edid or something? Any help is appreciated.
These are my custom options
hdmi_ignore_cec=1
hdmi_drive=1
hdmi_force_hotplug=1
hdmi_ignore_hotplug=0
hdmi_ignore_edid=0xa5000080
hdmi_group=1
# 320x240 - works rpi3
# hdmi_mode=9
# 576i - works rpi3
# hdmi_mode=22
# 576i quad - works rpi3
hdmi_mode=26
# 576i 100hz
# hdmi_mode=45
# 576i 200hz
# hdmi_mode=55
# 1080i
# hdmi_mode=39
disable_overscan=1
framebuffer_priority=2
hdmi_force_mode=1
hdmi_blanking=1
hdmi_pixel_encoding=1
hdmi_ignore_edid_audio=1
config_hdmi_bo*ost=6
sdtv_mode=2
sdtv_aspect=3
Thanks!
