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.

  [  1499.601] (II) intel(0): resizing framebuffer to 2560x1440
  [  1499.668] (II) intel(0): switch to mode 2560x1440@60.0 on DP2 using pipe 0, position (0, 0), rotation normal, reflection none

  The screen is Dell 2713H

  
  However there some errors in log
