HP Pro 3500 DVI to VGA Adaptor

Hi All,

My boss just recently purchased a bunch of HP Pro 3500s. They come with an integrated VGA and DVI port, which we use both for a dual monitor set up. Now when we connect to these ports using a VGA and DVI cable the set up works great. However, when we use a DVI to VGA adaptor on the DVI port, the second monitor is not detectable. Is there a way to fix this so we can use the adaptors? Any suggestions would be greatly appreciated.

Thanks,

SJ Wolf
