3 screens? |
|
|
I just tried hooking up a 3rd monitor to a win2k p4, 2.0g, 512mb ram box and
it isn't working. I have it connected to onboard vga. The dual head matrox
g550 drives 2 screens, but obviously doesn't see screen 3. Is anyone doing
this? Do I need to add a pci graphics adapter? Also, matrox doesn't seem
to care if onboard vga is enabled or disabled in BIOS. But, I bet if a I
added a pci card the onboard would need to be disabled.

Hi,
Most motherboards have an implicit beavior to disable their on-board VGA as soon
as any other card (PCI or AGP) has its VGA enabled.
In other words you *CAN NOT* have 2 VGA BIOS'es active at the same time.

As said, onboard VGA BIOS disables itself automatically when it sees another one.
If you disable VGA BIOS in your *add-on board*, then maybe you can have 3 outputs
active at the same time.
One more thing -- not all graphic chips have been designed to tolerate each other.
Some will simply refuse to coexist with another brand. Life stinks here unfortunately...
Good luck!

Hi,
the matrox parhelia is a good graphic-card to run a 3 monitor configuration.
