I have found this registry hack - Create a new DWORD "NoNvFBC" and set "1" in Data here - HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware SVGA DevTap
Then open CMD and CD to this folder "C:\Program Files\Common Files\VMware\Teradici PCoIP Server", and run "NvFBCEnable.exe - Disable". Reboot.
It works fine with 1 monitor, however then we add a second monitor to our Zero Client, it distorts the picture on both monitors...
