I connected the screen at home with the supplied high-speed HDMI cable via the docking station (Icy Box IB-DK2106-C). However, the system does not allow 60Hz@4K. I also tried it directly on the laptop (without docking station). Working in 30 Hz is quite a drain on my energy, and 2K or 1080p simply looks s****sse on this size :( The following is the maximum I can achieve (at 30Hz or 60 Hz): With docking: 29Hz@4K or 60Hz@1080p Without docking: 30Hz@4K or 60Hz@2K Means for me that both laptop and docking station are limiting. Does anyone have an idea how I can either (a) get my laptop to deliver 60Hz@4K (it does on other monitors too, e.g. in the office) or (b) find the right docking station that delivers at 60Hz@4K?
