I am not sure if this can be accomplisehd at all using the CUDA or Windows libraries.
Here is my scenario. I have 2 GeoForce cards installed on a Windows 8 machine. I will like a CUDA code in a C++ routine that will control the image display on one of the monitors.
My code will generate an image that I want it projected on one of the monitors while blacking out the full area of the monitor except the image that I want displayed in the middle.
Just think it like a Powerpoint slide that is rendered in FULL VIEW mode. I want the code to turn the entire background of the monitor to Black , White or Blue and displayed my vector image in front.
