9800 GX2 driving multiple displays issue

[Koraxen]

Hello guys!

I recently purchased an XFX 9800 GX2, but cannot get Windows to drive a second display. When plugging the DVI connector to port #2, one can hear the sound that is played when one connects a USB device. However, nothing new shows on the NVIDIA control panel. The regular "Set up multiple displays" option under "Display" is absent. The multiple display wizard is absent as well. The bootup sequence only shows on the monitor connected to port #1.

There is nothing wrong with either monitor, because both display correctly when connected to the video card`s port #1. Note that the GX2 *is* able to drive a monitor off port #2, if it is selected in the "Set multi-GPU configuration". However, this turns off monitor #1. They should both be on simultaneously, but for some reason the GX2 doesn't show the "Set up multiple displays" part in the control panel.

System status:
- I am running video ForceWare drivers 174.53
- I am running motherboard XFX 780i driver 9.46
- I am running a 100% fresh install of 64-bit Windows Vista

Hopefully all is clear.

Thank you,
- Koraxen

Are you running in SLI mode? If so, then you only get 1 display. Turn off SLI mode, reboot, and see what's available.

Make sure the nvidia control panel is showing the advanced options. I see the multiple displays option right next to the multiple GPUs option with the same drivers under vista64. Only difference is our chipsets.



May I ask a question? why 9800GX2 instead of 2x8800GTS in SLI if you have an SLI mobo?
