I am using Windows 7 Ultimate with a Nvidia graphics card and two DVI monitors. I want to measure some signals on the second DVI output over the analog path (VSync, video signal) on an oscilloscope.
However when I disconnect the second monitor Windows automatically disables the DVI output. This is useful for home users but really annoying for me. Can I switch that feature off and how?
Update: It seems there is no solution for this. So I switched back to Windows XP for now.
