Why do I receive an error when I try to use my Matrox morphis with the Image Acquisition Toolbox?

Clearly format : RGB32_-1442840129x1515803904 is invalid

It must be like RGB32_720x480. But 1442840129x1515803904 is huge Resolution and beyond ROIPosition limits. Contact matlab support team for invalid supported formats.

Moreover... There can be problem with frame grabber communication because of:

1) Frame grabber is not for windows (winvideo)

2) The driver of frme graber is not for (specific) windows

3) Error in driver code
