I am having problems with my KVM on a previously working configuration.  Now when I use KVM, the screen is GRAY

My previous (working) configuration is;

PC1 - (Custom computer Windows 10, amd r9 290 / i7 3770) connected 2 two 1080p 27" monitors.  One is samsung s27d360 and the other is HP 27xw.

PC2 - Lenovo T540p Win 10 laptop that is off in a corner out of the way

I would use PC1 to KVM into PC2 and use it on either monitor as needed.

I added a monitor after getting a good deal. Dell 27" 1080p.

I originally hooked up the 3rd monitor directly to PC2 and utilized Seamless to extend KM over to it in sort of a surround setup.  This worked great.

What i'm trying to do now is go back to a bit of a setup similar to what I had originally.  I want to connect all 3 monitors to my PC1 and KVM to PC2.  This fails.  Whenever i try to connect to the PC2 from multiplicity, there is just a gray screen.  I can hit the Windows key from PC1 and PC2 will recognize it, even though there is no video. 

Nothing has changed with software on either machine, only the addition of the third monitor.

Some things that i have tried

1. Reboot PC1 and PC2

2. Reinstall multiplicity on PC1 and PC2 and reboot

3. Install multiplicity beta from website and see if this helps.

4. unloaded and reloaded multiplicity on PC1 and PC2 several times

5. Updated video drivers for laptop/desktop.  Laptop has intel HD 4600 and NVidia GeForce GT 730M.

Does anyone have any ideas?

By the way, the reason I am leaning to this configuration is 1. To setup monitors in surround mode (eyefinity) for games and 2. be able to move my PC2 (work) KVM to different monitors depending on  how I'm sitting and what I'm doing.

Thanks all!
