Demetris, I was trying on a 50" Seiki 4K TV.
Just tried with a brand new LG 49UJ63 both with an old HDMI cable and a brand new HDMI 2.0 one. Same result.
As per siborg, 4K was working on Android.
Photos attached.
Try adding this
“echo "xrandr --output eDP1 --off && xrandr --output HDMI1 --mode 3840x2160 --rate 60.00" and modify for output and Hertz (60, 50, 30, 25). in the config folder to a file called "autostart.sh"
Hi, i tried from 8.0.2 to 8.2.2 and the 4k never worked (top left quarter static) with my MXIII-G
if i use android and select 4k, works ok, but if i reset with 4k to libreelec, the logo is show top left quarter of the screen forever
also with 8.2.2 the audio output uses S/PDIF and the output is PCM 2.0 always, before with 8.2.1 was HDMI (dd, dd+ or dts in 5.1) all ok
Try adding this "echo "xrandr --output eDP1 --off && xrandr --output HDMI1 --mode 3840x2160 --rate 60.00" (without quotes) and modify for output and Hertz (60, 50, 30, 25). in the config folder to a file called "autostart.sh"
