4K (60hz) over DP1.2 working on Linux on a T450s (w/ Intel i7-5600U / 5500 graphics)

I'm trying to get 4K (60hz) over DP1.2 working on Linux on a T450s (w/ Intel i7-5600U / 5500 graphics), when it works on Windows with the same setup (so it's not the cables), it finds the correct resolution (but I've tried tinkering with modelines, too) but when I try to use anything over 2560x1600 the monitor just goes black. I have the latest BIOS version 1.20. (And there is no setting in the BIOS for "force setting IGD Core Display Clock as 675MHz").

Is it something with Linux Intel drivers?

Hello, Tsarpf:

I would like to recommend you to check the Linux support forums for this inquiry or the OEM's support also.

http://askubuntu.com/ Ask Ubuntu

The graphics support from our side is very limited, drivers are not available for this HD Graphics.

Regards,
