Third card needed to run 3 monitors with SLI?

Hi Guys.

I've just invested in two 780 TI cards and a third monitor. I'm wanting the middle monitor for playing games on sli (not interested in eyefinity) however when I activate SLI it turns off one of the monitors?

Is there a way to run three monitors without sli deactivating one of the monitors ?

Only other option is buy a very cheap third card just to run the third monitor.

What's the best solution here ?

I thought for Nvidia, you have to plug the 3rd monitor into the 2nd card for their setup whereas AMD is all on 1 card, but I could be mistaken.

How do you have the 3 monitors hooked up, input wise?

I have the central monitor and the right side monitor in one card and the left side monitor plugged into the second card. It's the left hand monitor that switches itself off when I enable SLI. When I disable SLI it come back on again.

It's more a pain than anything. I just want to leave sli constantly on.

Have you tried running all the monitors from the primary card?

I'm afraid I can't as each card has only two monitor connections.

There must be someway of activating sli without it turning off one of the monitors? I guess I could buy a very cheap third card but seems rather silly since each card can run two monitors each ......

Only two? Or do you need to use an adapter to make use of either of the other two?

I'm not sure I know what you mean mousemonkey.

Each nvidia 780ti has two connections at the back for two monitors, but since I have Two 780 ti cards that's four connections in total.

I have one card running two. (Middle monitor and right side monitor) and arcing graphics card running left side monitor.

Both card are connected via a sli bridge and one SLI is enabled it switches off the left screen . I'm just using the middle screen for gaming as it's the bigger screen.

Yeah they can. I'm running three monitors which run absolutely fine. But when I enable SLI it switches off one of the three monitors.

That's because they all need to run from the primary card.

Yes I see what you mean by that link. But I think those other connectors are for something else. They only have two monitor connections.

Apologies for my lack of terminology

You can see what I mean from the picture of the rear of the card here.

Get a DVI to HDMI adapter and then plug the third monitor into the middle bottom port on the primary card.
