Thanks for the suggestion.
I went through these steps. So right now I have my desktop connected to the dock. If I have both monitors connected through the dock, what I see is my Windows background on both monitors. I can see my mouse cursor move. If I try to open a window or something it looks like it is opening a window but I can’t see it on either of the two monitors. I can see in the task bar I have a folder open or Chrome open, but I can’t “open” it on either of the two monitors. Its almost as if it is trying to display on a different display that is even hooked up.
I did unplug the HDMI from the dock and went straight to my computer so at least I could open this window to type a response. I still have the second monitor connected to the dock via the DVI port. Interestingly enough, when I do this (HDMI to PC and DVI to dock) I can use both of the monitors exactly how I would like to be able to use it.
Just to test, I disconnected the desktop from the dock and connected my laptop. I have display on my laptop and on my one other monitor. The larger monitor doesn’t display because that’s connected to desktop via HDMI. But if I connect that HDMI back to the dock, I again have my laptop and two external monitors displaying what I expect from the laptop.
If this makes any difference, when I have both of my monitors connected to the dock, and my desktop computer connected to the dock, on what I assume is monitor 2, I can scroll my mouse over to the right and it enters monitor 3, if I go left it goes back to monitor 2 and if I continue going left it scrolls OFF monitor 2 to what I would assume is monitor 1, except there is no monitor 1 in this case.
