2nd x1c - displayport (version / resolution / frequency)

[daten]

Hey!

What kind of display am I able to drive via DisplayPort with the 2nd gen x1c?
To be more precise: am I able to drive an external 4k display refreshed by more than 30Hz?
What version is the DisplayPort about? 1.1? 1.2?
Also, does the used graphics hardware (intel 4400 / 5000) make a difference here?

Thanks a lot!

Depends on the GPU - HD 4400 units can only drive 30Hz 4k, HD 5000 units can drive 60Hz 4k

Thanks a lot!
Where do you have that info from?
Is there any official source for that?

For example on that (German) site[1], they recently added likewise specifications and are now stating:

3840x2160 (Mini DisplayPort)@30Hz; 2880x1620 (HDMI)@60Hz
