Looks like I'm having the opposite problem from everyone---I connected a monitor to the onboard VGA connector and it works fine. Leaving that setup connected, I then installed a video card and connected the PCI-Ex16 video card to a second monitor and it works fine---except I don't see any video on the first monitor. If I look at the BIOS setting, it is grayed out under the integrated peripherals. Does anyone know how to re-enable to onboard? Thanks. RIch
It seems like your motherboard only wants to enable video from a single source. I don't know many that allow both onboard and discrete graphics cards to operate, because once you install the video card and connect a monitor to it, many motherboards automatically turn off the onboard video. What kind of motherboard is it? Does the video card you added have more than one connection/port? If so, try plugging both monitors into that one.
Can you tell what make/model the motherboard is? What model of e-machine PC are you working with?
If you disconnect the second monitor from the graphics card, do you get video again on the monitor plugged into the onboard video controller?
