I have my Lenovo T460 connected via an Ultradock 90W to an Asus PB287Q via Displayport which according to (Display and Video Output Configurations - Docking Stations ) should enable 3840x2160 at 60Hz, however I am only able to get 30Hz.
How can I get 60Hz display? Movement (e.g. mouse) is jerky at 30Hz. Using latest production drivers.
Thanks in advance,
