I have Multipplicy Pro 3.5 Build 00096.kvmpro, installed on 6 computers (5 Windows 10 Pro, 2004; 1 Server 2016).  One of the WIn 10 machines is primary; all others are secondary.   The program works perfectly on 4 of the 5 secondary machines.

The 5th machine is another story.  I can connect to it and I can send it a Ctrl+Alr+Del, to which the machine responds aw well as to any other keystrokes such as entering a password following the three-key salute.  However, there is nothing displayed on the primary computer, the screen remains blank.  

I have removed Multiplicity from the computer, removed it from the list of computers on the primary computer, and then installed the software and added it back into the list of computers on the primary machine.   All this has made no difference at all.

The computer in question is an HP Z-Book 15 G3 (a laptop), i7-6700HQ, 16 GB RAM and 369 GB of free disk space.  All drivers are up to date per HP's softpaq manager.   It has two onboard/built-in video cards, an Intel HD Graphics 530 and an Nvidia Quadro M1000M.   No external monitors now or ever.

I have found this problem goes away if I change the BIOS to use only the Nvidia "card".    This is not a fix because I lose the power savings of the machine using the Intel "card" for undemanding/light display tasks.

I had this same problem with the previous release of Multiplicity (3.44) and hoped it would be resolved with 3.5.  No such luck.

Thank you.
