I tried asking this question in the s912 thread.
I am running libreelec 8.1.9 version on s912 h96+ box. and I have old Philips TV.
on versions before 8.0.2.e you could force the rgb output with this command
#!/bin/sh echo 1 > /sys/class/amhdmitx/amhdmitx0/output_rgb
however the newer version of libreelec doesn't support this configuration via autostart.sh file.
if I downgrade to 8.0.2x and execute this command I loose audio via hdmi.
I have read here something about configuring 8bits/10bits display to force rgb.
I was wondering if someone here could help me with this issue. I would like to keep up with the updates of libreelec, but I am too beginner to know what and where to configure, so my TV screen does not randomly go green/pinkish when I am in the middle of watching a movie.
I asked this question in s912 thread too, but only received short replies and no workarounds. hence why I am asking it here.
please provide me with some guidance how to fix this problem. thank you
