I recently bought a second monitor for my desktop and connected it to the second output on a nVidia GeForce 9800GT and installed UltraMon to manage the dual displays, along with the nVidia nView Desktop Manager for a few features. Ever since switching to dual monitors on the desktop, I haven't been able to log in using Remote Desktop Connection (RDC) from my laptop, which is a Macbook Pro running the latest stable version of the RDC client for Mac. When I try to log in, the client on my laptop shows a blank black screen and my monitors on the desktop show the same. When I quit the RDC client on my laptop, my desktop still shows a blank black screen on both displays and I have to hit the reset button to get it working again. Does anyone know how to solve this problem?
In short: Remote Desktop Connections worked beautifully to my desktop (Windows XP Pro) from my laptop (Macbook Pro running Snow Leopard) until I bought a second monitor and set up a dual display environment on the desktop. Now, both client and host screens go black, and the host has to be reset in order to be used again.
