thanks for the answer.
How do you connect? With the Surface Dock or directly with the surface?
I get with both no screen at all.
Which type of cable do you use. Mini-Displayport --> Displayport
I´ve got my Surface pro 4. (i7, 8GB RAM, 256GB)
+ the new Surface Dock
And a DELL U2515H 2560 x 1440 at 60Hz --> And the Problem is that I get no picture on the Dell.
Connected with the Displayport cabel - direct on the surface or on the dock. No Picture. I used the the Dell for some months...
