It seems most nVidia cards only come with 1 Digital Port slot so how do people go about hooking three 120hz monitors up?

Cheers
 
Not 100% on this, as I connected mine to 2 cards and used 3 DL-DVI connectors, but I believe you can use any connector but you won't get them all running at 120Hz.

I have always made sure my cards come with 2 DVI's though

I'm not overly impressed by those adaptors. They seem very sensative to the voltage supplied by the USB connector, usually plugging this into a motherboard USB port wont provide enough power. I had a powered USB hub, but it was still flakey.
This was with AMD cards, but I doubt it makes a difference does it?

If your monitors have DisplayPorts, can you not connect 2 via DL-DVI and the other using a DisplayPort?
 
£80! I'd just buy another AMD card to not pay that.

Googaly, they do indeed, I wasn't sure what was capable of 120hz connection wise, I always thought the DL-DVI you couldn't use both or something?

You could on my 670s. I had 2 cards and connected 2 monitors to 1 and the 3rd to the 2nd card. All using DL-DVI.

ah, interesting.
So it does use the DisplayPort, but needs a DP-to-DLDVI adaptor?

Although that is for 3D Vision and so I'm wondering if it's a monitor thing? Surely the card doesn't know you're using an adaptor?

In which case could it depend on if Andybtsn is planning to do 3D Surround or just wants 3 monitors at 120Hz?
 
That's 3D Vision.

I think... and it is a while since I tried on a single card... that 120 Hz just works by:

DL DVI
DL DVI
DP

It definitely used to work and give 120 Hz like that.

Someone has just posted 2 of those on the MM for £45 if you need one :)
 
Cheers :)

I can't justify the extra cost though, if I can't get 120hz I'll just get an AMD card, shame, I wanted to try nVidia this time.

Apologies Andy that's the wrong adapter, google

Dell / Bizlink Active DisplayPort to DVI (Dual Link) Adapter

I take it your still using the BenQ's you bought off me?

I have used one of these adaptors, albeit the active display port to DVI and it works fine and reliably with my 120Hz monitor.

I had a think about this again and 120 Hz definiely works across all 3 monitors on a single card. I tried it before plugging in my second 680 when I had those.

Two on DL DVI and one in DP. You may need adaptors if your monitors do no support those connection types at source.
