I don’t have another power supply yet, but i’m sure that is ok.
I have Hp Pavilion 22xi that support 1920×1080 and lower.
When i see “retropie project” my keyboard is responding and i can switch tty. Then in tty2 I login as pi\raspberry and i see input dialog for emulation station.

It’s blank.

Problem returns after “sudo update, sudo upgrade”. This is similar to the incorrect configuration of video. In which config I can play with video?
