Multiple Monitors

[dawnm.jordan]

Hi Everyone,

I am trying to configure 3 monitors on my workstation using a dualhead
nVidia dvi card, and a 'Y' splitter (dvi/vga). What's happening seems
a little strange, when I boot the system montiors A & C are both
active, and show all the POST and BIOS info and continue until Windows
XP begins to load, once Windows starts monitor A becomes inactive, and
the display moves to monitors B & C. Once in Windows, monitor A is
not detected.

I guess I should add that monitor A is using the vga connector and B &
C are both using DVI.

Any suggestions would be greatly appreciated!

Dawn

Have you gone into the Control Panel "Disply" applet and modified the display settings such
that it knows you want multiple monitors ?

I'm not sure what you mean.

I stated...
"Have you gone into the Control Panel "Display" applet and modified the display settings
such that it knows you want multiple monitors ?"

That means...

Go to Control Panel.
Find the Display icon (Display applet)
Go to the "Settings" tab.

Setup for multiple monitors/displays.

The Post & Bios info are shown before the win video drivers are loaded, &
when they are loaded it sees only the monitors configured in the nVideo
display settings, There should be an Nvideo icon in your task bar which
allows you to configure the multiple monitors, whether this will enable the
3rd monitor I cannot say

 

[dawnm.jordan]

I understand what you mean. I have attempted to configure using both
nVidia and Windows XP, but neither recognize that monitor A even
exists, so I can't configure it... nVidia even has a 'detect'
function which I ran, but it still didn't detect the monitor.

Perhaps you don't really have a dual head card, and it is an Either OR card?

 

[dawnm.jordan]

It's the VGA Monitor on the splitter that is not working, the two DVI
monitors are working great (the card is dualhead dvi)...

Is it possible that running a splitter with a VGA connector on a DVI
card just won't work? Though that would be confusing because our
company has about 100 dell Optiplex form-factors all running dual
monitors using this same splitter off a single DVI connector.

Not sure what your configuration is any more. You have a 2 output card
or three? What is the splitter for? Is it just a y-cable or a real "Dual
head to go" splitter?

 

[dawnm.jordan]

I am trying to configure 3 monitors, and have 2 DVI outputs on my
machine. The splitter cable is very similar to the one pictured here:
http://www.pccables.com/cables/01780.htm

Then I have one dvi monitor hooked directly to the card, and another
dvi monitor hooked to to the dvi end of the cable, those two are
working fine. The third monitor is hooked to the vga end of the
cable, that is the one that is not working.

Does that make it a little clearer?

Note: Both Signals have to be present on the DVI-I Port for this to work.

the note would indicate that the the VGA analog signal goes away on your
system when you have both DVI ports connected
Perhaps the card is only capable of 2 monitor signals, giving you the
choice of 2 SVGA, 2DVI or one of each.

You may be right... thanks for your help!

Simply put, if the Control Panel "Display" applet only shows two monitors, then you can't
use three.
