It has nothing to do with video monitor, video card, & NI-IMAQ driver version. When I use NI-MAX 3.0.2 to get picture, the picture is black & white. The problem is related to Windows 98 kernel. The LabVIEW 5.1 application exe file use kernel to get new setting for black color during running LabVIEW 5.1 application exe file. It may be related windows 98 kernel, LabVIEW 5.1 & API. Or it may be related to driver setting because it has color from blue to red
Thank you for your support.
