I have a single monitor display, and two graphic cards on a Dell PC. I want to set one as the primary card, but I want to use it for GPU programming, and the second one to draw the video display output on my monitor. I have already tried changing it through BIOS, but it only shows which graphic card I want as the primary one, and draws the video output through that one (which I do not want). The NVidia settings panel only shows the current topology, without offering any option to alter it. Any ideas about how this can be done?

When you set one card as primary you only set it as the primary card for video output. It should not inhibit using the secondary card for processing tasks. – Will.Beninger Jun 4 '13 at 15:28
