The background color of your picture should not be changing if your image environment, video monitor, etc. are the same for both systems. Do you see the problem if you use the camera from the first machine on the target machine? What if you use swap out the PCI-1407s between the two systems? Also, are you running the same version of the NI-IMAQ driver on both machines?

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.

Let's try to narrow down the issue a bit. Try displaying an image from file rather than the acquired video data and see if the background color still changes. If you have not already done so, I also suggest running the executable on the development machine and on a different operating system, to possibly eliminate or confirm Windows 98 as part of the problem.

Please let me know the results. Best wishes!
