How to set up Dual Monitors??

[caz67]

Hi Guys,

Excuse me for such a noob post. I just got back my 19 BenQ, and i want to set up dual monitors with my Dell. I have both monitors on one vid card, set up using DVI on 2 x 7800GTX in SLI mode.

I have tried to set both monitors via display properties. My Dell is running as monitor number one and i have tried to set the Benq up as number 2 at 1280x1024. Now both screens will show BIOS and first boot screen, however the Benq wont post into windows?? It keeps saying no signal detected??

I have tried to tick extend windows to desktop, and i click and try to save and it wont allow it to happen.

Will i get windows up on both screens??? or will it just be windows on the primary monitor???

Is there anything that i need to do differently??

thanks

I don't have an SLI setup, so I'm afraid I won't be much help. However, have you tried to switch them to see if you get the same result with the 19BenQ as the primary monitor?

Tried moving one monitor to the second card?

Nvidia does NOT support a dual monitor set up on SLI, its queer, but its the truth. Hopefully sometime soon they will fix this issue

Wow. I'd be really bummed. I couldn't/wouldn't work without dual monitors. But, having gone through the Voodoo 2 SLI thing in 2000, I refuse to ever buy into another SLI design.

Voodoo 2 SLI was:
1) Expensive
2) Incompatible with some software.
3) Of marginal advantage in the best case. Sometimes it was SLOWER than non-SLI.
4) Quickly obsoleted. The next iteration of Voodoo card (Voodoo 3), was much faster (and much cheaper) than two SLI'd Voodoo 2 cards.

Maybe this new SLI stuff will be better. I'll check back in a year. 🙂
