I got mail from Simon. I will try to work with it tomorrow.
All the signals are running 60Hz incl. the projectors, but I think the capture card are runing 50Hz (Pal).
I will inform you tomorrow.
yes pal is 50/25FPS. it is one of the critical things when doing video input to use the right refresh rate.
what exact resolutions are your screens?
including 2nd output.
