I recently bought a PCI graphics card and an LCD monitor for my computer. They both work great, and I figured it would be cool to hook up my old CRT monitor as well. Combine this with a "The Matrix" screen saver, and you've got a cooler computer than anyone else on the block.
Here's the setup I'm aiming at:
LCD --> Connected to --> PCI card (primary monitor, used for gaming)
CRT --> Connected to --> Motherboard graphics port (secondary monitor, for the heck of it)
I shut off my computer, attached the CRT to the Motherboard, and powered back up. When I logged in, the CRT monitor stayed black, but the power light was green, signifying that it was connected. I figured that Windows XP Pro didn't automatically extend my desktop, so I went into display properties and clicked the Settings tab... nothing. Normally, it shows two gray blocks representing the two monitors, but there was only the default Settings screen. I tried turning my computer off, plugging the LCD monitor into the motherboard port and doing it that way, but the LCD did the same thing as the CRT; had a green light, but showed a black screen. I tried plugging the CRT into the PCI slot, and it worked. I also checked the device manager, and it only showed one monitor attached, and interestingly the only thing under Display Adapters was my PCI card.
Apparently, my monitors are able to recognize the onboard graphics port on my motherboard, but the rest of my computer does not. It isn't a problem with the hardware because the monitors wouldn't recognize the port if it was broken. Both of my monitors work, so it isn't that either. Can anyone give me instructions on how to get XP to realize that it has an onboard graphics card? Thanks.
