I have a screen resolution problem.
The max. offered setting is 1920x1024 but my Dell U2711 monitor is 2560x1440.

System specifics:
Ubuntu 13.04, ASRock Z87E mainboard, Z87 chipset, Core i7 4765T (HD4600 integrated GPU)
ASRock claims their board supports up to 4K x 2K resolution when using HMDI interface.

I used the Intel Graphics Installer to update the driver but this made no difference.

I have very similar problem.

Max. offered setting is 1920x1200 but my DELL U2713HM monitor is 2560x1440.

Ubuntu 13.04

Intel DH87RL motherboard, Core i7 4770K with HD4600 graphics.

This is what Xorg.0.log file reports:

So, in this section resolution 2560x1440 is present.

I changed the cable from HMDI to Display Port.

The full monitor resolution of 2560x1440 is now available.
