Title: Resolution >1080p (like 1440p) doesn't work on Intel Braswell ( Asrock N3150 ) Status in linux-signed package in Ubuntu: Confirmed Bug description: 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.
