Hello again Nate,
Sorry for the late reply, I do have a workaround but it involves setting up a virtual machine and dedicating 2 of the four monitors to that machine (they are still available to you to overlay a browser and such, but the VM will only see the two screens). You will need a separate windows license and installation disk to use on the virtual machine.
The way I use it is I only run the AWS client on the VM (so it doesn’t need a ton of resources to be allocated to it), I then run AWS in fullscreen mode so that it utilizes both screens that I have assigned to the VM, I use these for my Ninjatrader charting and I use my remaining two screens to run the Apex scanner and the chat room or any other software I may need at the time. I have a youtube video I did a few weeks back as a quick tutorial if you are interested (link below).
Let me know if you need any other help.
