Hello Aleksandr
please provide more information, what type of video card do you have?
Have you configure the card so you can watch an image with MAX?
I suppose the card has the ability to capture more than one image at a time is that true?, however most of the cards that I know of, have several inputs but you can only display one image at a time, you can swith between them and capture and image from another input, to capture more than one unit at a time you would need to open/close sessions with the instrument/card such that you are switching from one input to another
