Dual monitor problems

I am needing support again as i am now stuck with what to do.

I have a mobo with a Nvidia Nforce 630i chipset and recently got a 15.4" widscreen tft free from a friend and want to set it up alongside my 21" crt for dual monitor. Now my motherboard has DVI, VGA (d-sub) and HDMI but both my montiors have standard d-sub vga connectors on them so i tried connecting the main monitor to the d-sub connection and then connecting the secondary monitor to the dvi using a dvi to vga.

i don't get anything displaying on the 2nd monitor and it won't show in in the nvidia control panel so all i get is the "use only one display" option. I know the 2nd monitor works as i had that plugged into the d-sub connection when i was installing windows.

 

Maybe your video card can only push one display?

 

Is your nvidia forceware up to date? I used to have the same problem with my card and that solved it.

Anyway, the video card must detect another monitor before showing the dual monitor options, otherwise you won't see anything related to it in the control panel. Maybe the video card can't detect the 2nd monitor because of the dvi to vga adapter, did you use it before?

 

Dual monitor setups are still unnecessarily buggy sometimes. If you haven't already, you might want to check to make sure that everything works by going through a couple of configurations:

1. New monitor works by itself through the primary VGA
2. Old monitor works by itself through the DVI-VGA adapter
3. If (2) works, try the new monitor through VGA and the old monitor through the DVI
4. Try lower resolutions
5. Update your video & MB chipset drivers

 

updating the forceware drivers and will get the latest nforce drivers as well.

i know i can do dual monitors even though its onboard as i read somewhere that says it can push two displays.

 

It can push two displays but not two dual analog displays....

If your DVI connector doesn't have the 4 pins where there's a cross-like slot on one side, then it cannot output an analog signal as those 3 of those are the RGB lines.

Basically, your connector is most likely DVI-D

my dvi connector is a dual link

 

Look at the pinout, which of them looks like the one you have?

Dual link can be found in DVI-I or DVI-D.

 

Check your BIOS settings...could be an option set in there.

 

i meant to say dual link DVI-I

The only dispaly setting in my bios is for the HDMI connection
