[ROM] Rock5A/B AndroidTV 12 by mo123

@mo123 I tried two different HDMI 2.1 48 Gbps cables and both ports on the rock5b. This one:

and another one, I don’t remember where I bought it. Both cable can output 4k120 from my PS5 to my LG C1 TV (the hdmi port is set “gaming/pc mode”).
Furthermore, I tried the following image:

Armbian 23.02 Jammy Gnome Feb 27, 2023

Android and Armbian both max out at 4k60… As soon as I select anything above 4k60 (100, 119, 120) the screen turns black.
