I've had to remove my graphics card for some time and I've just connected my screen to the Gigabyte Z390 AORUS Pro motherboard output HDMI. But I can't change the monitor resolution to 2k (1440p), even though the Gigabyte spec states the onboard graphics has 1 x HDMI port, supporting a maximum resolution of 4096x2160@30 Hz, Support for HDMI 1.4 version and HDCP 2.2, and the CPU's specs for UHD630 graphics onboard calls for 4096x2304 .

I've followed steps here but it's not working, just changed the Login screen to 2k resolution.

Also I've copied the bin that describes this post, without any result.

Some outputs from related commands.

In my Windows partition, all works perfectly without any configuration so I suppose that all is OK in BIOS configuration.

Finally I installed Ubuntu Budgie 19.04 as @K7AAY recommended and all works fine.

    So, it's something specific to Ubuntu 18.04 which uBudgie 19.04 does not use. – K7AAY Jul 25 '19 at 21:43
