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
