Actually, I have many problems with external monitors. Let me explain: The WD19S docking station has 3 outputs for monitors: 2 Display Port and 1 HDMI port. The ideal configuration for me is to use the 2 DisplayPort connectors with 2 external monitors AND the display of the laptop. Problem 1: If I use ONLY the HDMI port, the resolution of the external monitor is 3840 x 2160 (16:9) and this works without any problem. If I connect the same monitor using a single DisplayPort connector, the resolution is 2560 x 1440 (16:9). Also, the size of the screen is different: with HDMI the monitor is 28'' but when I use the DisplayPort connector the size is 27'' Monitor is Samsung U28E570D Problem 2: When I connect two monitors with DP the gnome utility becomes crazy (see attached image, ) and only one monitor works. Note: I'm using two equal monitors: Samsung U28E570D Thank you!
