my wishes for the furture:
if there had been be a hyperion-version for LineageOS (based on Android) running on a Pi 4
( look at this: https://konstakang.com/devices/rpi4/ )
the screen content could be transfered directly to LEDs via gpio, as normally possible
with raspbian or retropie for example .
So no converter or seperate reciever needed anymore and all things from one hand
on an android system.
