Dell Optiplex 740, Samsung 971p and DVI to VGA adapter problem

Last Modified: 2013-11-08
I have a Dell Optiplex 740 with a built in VGA Geforce 6150 LE. A Samsung SyncMaster 971P monitor with a DVI cable and a DVI to VGA adapter that I am trying to get working.

The video card works fine with a VGA monitor, the Samsung monitor works fine on another computer and the adapter works with another hardware setup by using two adapters and then plugging it into a DVI video card.

Is there a problem with the hardware I am trying to put together or is there a way to get this working? Using the adapter on the computer you get no screen, the monitor automatically adjusts from digital to analog but nothing ever comes up on the screen as far as I know there is no way to go to a menu and force the monitor to analog, I am helping someone out with this and don't have first hand experience with it.

Is there something in the BIOS that needs to be changed so it will work with the adapter or maybe we just got the wrong adapter for the job.
