It seems that it tries many times display but no result, But 1080p works without issue. Not sure if it's some bios settings, now it is in UEFI mode. I will investigate it further.
I turned off the other screen, it doesn't help
In logs it looks pretty normal, but the screen is turned , but blank and the icon of the chainged source is coming from time to time.
