I upgraded to the UD-ULTC4K docking station. Before the upgrade I was using a lenovo docking station but it did not support 3 display port/hdmi monitors with the use of a usb video card. This worked poorly, hence the upgrade.
Prior to the upgrade I was able to use custom rdp files that would use two of my three screens. Now those same files use all the screens and the applications opened in the remove environment span all three monitors. I have tried editing the the rdp files with different monitor combinations but they keep stretching to all of the monitors.
span monitors:i:1
use multimon:i:1
selectedmonitors:s:1,2
My only options that work are 1 monitor or all monitors.
