Can't get dual / extended screen to work, gives boot-time error

[BSimp3]

Hello all,

I get this on startup:

This computer has an add in graphics card, but the monitor cable is plugged into the integrated video connector. To attach the monitor cable to the add-in graphics card:

1. Shut down the computer

2. Plug the monitor cable into the add-in graphics card connector. This may require a video adapter or video adapter cable.

3. Turn on the computer

I am running a Dell, GX620 Optiplex with Intel Pentium D 2.8gHz processor, 2 gb ram, running windows 7 Ultimate. The Graphics card is a brand new Radeon Saphire HD5450

Theoretically, I should be able to enter BIOS and select the OnBoard VGA as always enable, and the PCI-E as enabled.

However, I seem to only be able to do One or the Other, not Both.

I want extended desktop across 2 VGA monitors

Can anyone point me in the right direction?

Hello CrazySparky, thanks for joining the Intel Community.

It is important to tell you that some systems do not allow using the onboard video and a video card at the same time. Most of the time, once you installed a Video card on the motherboard; the onboard video gets disabled automatically.

I would recommend you to contact DELL in order to check if your system is capable of using the onboard video and the video card simultaneously.

Regards,
