1. My JVC TV supports HDMI2.0 and can work well at 4K@60Hz with my old S912 android TV box(R-TV S10).
2. When I turned on GT-king first time, it automatically select 4K@60Hz and the screen kept on and off forever. Then I connected it to another 1080p TV and selsected 1080p 60Hz manually. Went back to 4K TV and I can see the 4K 60Hz option in settings. After switch to 4K@60Hz manually, the screen started to on&off again.
3. I turned off the CEC fumction of TV>-king, it's the same. |
