I’m on the 002 build now, still getting tearing in the UI, was that not fixed yet?
According to LibreELEC (Leia) 9.2 ALPHA1 with Raspberry Pi 4B Support – LibreELEC, LibreELEC Kodi currently outputs to 1 screen. I'm wondering if it would be theoretically possible to output to both HDMIs ports in mirror configuration. I understand Linux should allow this via command line using xrandr --output HDMI1 --same-as HDMI2. Shouldn't it be able to mirror in LibreELEC as well? Can any LibreELEC devs answer this?
If you're wondering why would anyone want this, this might allow people to forgo buying a HDMI splitter (for example, to connect to a soundbar with HDMI 1.4 and a 4KTV with HDMI 2.0)
Yeah I raised a feature request for this for this exact reason.
I've read that it's possible to configure which HDMI output will get audio (and CEC), so I guess it could maybe work.
I have no idea though how Kodi will react to two active video outputs and unfortunately I have no easy way to test this. Maybe someone else could chime in and check if this works.
I have the same scenario(4K TV, 1080p AVR). And tested it.
Connecting HDMI_0 to AVR and HDMI_1 to LG OLED only outputs audio and video to HDMI_0. HDMI_1 has no signal.
Thanks! Would be great.
The Rpi 4 has dual HDMI outputs.
Currently only HDMI_0 is initialised for audio and video.
It would be good to be able to send Video down HDMI_0 and Audio down HDMI_1.
This helps in scenarios where the TV is 4K, but the AVR is 1080p, and you still want to send PCM or DTS HD (or other lossless audio) to an AVR (which RPI 4 hardware has support for).
