Linjo,
Well, initially it (3D Renderer) was set to Disable. I won't be using any 3D type graphics so I assumed I could just leave that do disabled. My only requrement is to support a max of 4 montiors. And I set that and the max resolution in the pool - on the VM side the video was set to Auto Detect.
However, I have played around with the 3D Renderer and set it to Manage using vSphere, automatic, etc. But so far I have not had any luck. Are there any recommended "basic" settings? Again, my only video requirements will be supporting up to 4 monitors.
