I have a Raspberry Pi 4 connected to two identical displays, one on each of the HDMI out ports.
I am running LibreElec 9.2.8.
When I boot the system, I see the splash screen on both screens. As soon as the Kodi app launches full screen, its only one one screen, and the 2nd is black.
I've seen a lot of references to "Kodi only support clone mode" and not extended displays. However, the Kodi forum has been taken offline so a lot of the content out there just links to dead links.
I've tried the following settings in /flash/config.txt
hdmi_safe=1
max_framebuffers=2
hdmi_force_cec_address:0=65535
hdmi_force_cec_address:1=65535
hdmi_force_hotplug:0=1
hdmi_force_hotplug:1=1
hdmi_group:0=2
hdmi_group:1=2
hdmi_mode:0=4
hdmi_mode:1=4
hdmi_pixel_freq_limit:0=0x11e1a300
hdmi_pixel_freq_limit:1=0x11e1a300
Does anyone know how to get 2 identical displays?
