What happens if you add the resolution using CRU instead? These drivers should work with CRU:

Windows 10: https://downloadcenter.intel.com/download/30196
Windows 7/8.1: https://downloadcenter.intel.com/download/29970

I don't know. I tried CRU with the driver I am currently running, but I am either not using CRU properly, I don't understand how to use it properly or it won't work with that driver. or a combination of all 3!

I read the instructions on CRU on this forum, but nothing seemed to work. So I don't know what I am doing wrong.

According to the specifications of this machine it shows it should be able to do 3840x2160 @ 60Hz. Which is does. But only at CVT-RB timing. Which is a reduced blanking timing if I understand it correctly. The specs also say something about reduced blanking, so perhaps I am just at the limit of what the hardware/BIOS can do?

I will download and install that driver and try again after I get off work.

Thank you.
