This is related to my post at https://communities.vmware.com/t5/Horizon-Desktops-and-Apps/Horizon-Desktop-Locks-up-at-Black-Screen...

Here is my current problem.  I have Dell Wyse 5070 clients running ThinOS 9.1.3112.  I have two systems setup to do some testing.  One has a single monitor while the other one has dual monitors.

I can connect to a desktop using the Blast protocol however, the zero-client with a single monitor locks up at the desktop with the Project to a Connected Screen dialog box.  It will stay frozen until the resolution is changed on the zero-client.  That seems to unfreeze the desktop.  I attached an image of what the desktop looks like when it freezes.

The zero-client with dual monitors does not have this issue and works as intended and all is right with the world.

I thought this was strictly a Wyse issue until I tried accessing the desktop through the web browser.  Once again, the desktop loads but freezes up at the same spot but if I resize the browser window it resolves the problem.

I have tried changing the master image hardware config from 2 monitors to 1 monitor to automatically detect settings in the video card settings.  I have adjusted the video memory.  I tried setting the screen resolution to different settings, nothing seems to help and I really need to get this resolved.

I attempted to force PCoiP instead of Blast but that is causing other issues that I don't have the time to troubleshoot.

Any suggestion will be greatly appreciated.  Thanks.
