--------------------------------------------------------------------------------------------------------------

I have read a lot of threads in this forum about how to run multiple monitors when SLI is enabled. And it differs from thread to thread and I don't think the solution I found has been mentioned earlier (but I could be wrong). Actually I was thinking about this "trick" before I decided to tested it and before I asked in here, and when I got the time to test it, it actually worked right away. I was afraid that my trick would be reset after a system reboot but it didn't which makes this solution perfect in my eyes.

One way to use multiple monitors is to use an adaptor, but this adaptor will just tell your graphics card that all your monitors are one big monitor and due to the large resolution the game performance will be much worse than playing on one monitor. The other way to run multiple monitors is to have another graphics card not running in SLI to handle the other 1-2 monitor you would like to connect, and let the SLI-cards handle the primary display. And this is very confusing since some people seem to have succeeded while others didn't.

It is said that an ATI-card combined with 2 Nvidia Card in SLI will work in Windows XP but not in Windows Vista because Vista doesn't allow two different video card drivers and unfortunately I haven�t been able to test if that's the case. But I will try ATI in Windows Vista later, but I don't have access to a card at the moment.

[size=4][b]Requirements for this Guide[/b][/size]
There are a few requirements to be able to succeed with this and those are:[list]
[*]2 Nvidia Graphics Cards running in SLI
[*]1 other Nvidia Graphics Card (PCI or PCI-E)
[*]Windows Vista (32bit or 64bit)
[/list]This guide has only been tested on Windows Vista. Some replays in this thread report about problems in Windows XP and that it's not working.


[size=4][b]The Guide[/b][/size]
The two cards running in SLI will handle the main monitors which you would like to use when you play games or other graphics hungry applications. This is exactly like the same as before. The second monitor, or even the third if you have a total of three monitors, will be connected to the other graphics card not running in SLI. Make sure you do these changes before you continue.

Also make sure you disable SLI, if activated and have all three cards installed in your computer before continuing.

When you start your computer with two similar cards and another Nvidia graphics card, you will not be able to activate SLI. I think Nvidia detects that all graphics cards are not the same and have no working SLI bridge between them and automatically disables it. But don't worry, we will activate it anyway!

[size=4][b]1[/b][/size]
If you open your [u][b]Display Settings[/b][/u], it should look similar to this:

[img]http://web.telia.com/~u46218134/multi-monitor-guide-sli/all-monitors.jpg[/img]
There should be 6 "monitors" to attach if everything is correct so far.

[size=4][b]2[/b][/size]
Now go to [b][u]Device Manager[/u][/b] by right clicking on "My Computer" or "Computer" as it's only called in Vista and click "Manage". Click on the Device Manager and expand your "Display Adaptors". Now [b][u]Disable[/u][/b] the graphics card that you are not going to use in SLI. In this example it's 8600GT since the two 8800GTX will be used in SLI.
[img]http://web.telia.com/~u46218134/multi-monitor-guide-sli/disable-third-card.jpg[/img]

You will get a question asking you if you really want to disable it, but for this guide to work it's required.
[img]http://web.telia.com/~u46218134/multi-monitor-guide-sli/disable-third-card-2.jpg[/img]

- [u][b]Restart your Computer[/b][/u]


[size=4][b]3[/b][/size]
Now when the computer has been restarted, you can activate SLI in your control panel.
[img]http://web.telia.com/~u46218134/multi-monitor-guide-sli/enable-sli.jpg[/img]


And you should restart your computer after enabling SLI, even if you didn't need to.
[img]http://web.telia.com/~u46218134/multi-monitor-guide-sli/enable-sli-restart.jpg[/img]

- Yes, restart the computer...

[size=4][b]4[/b][/size]

Now the other graphics card that you disabled in [b][u]Device Manager[/u][/b] should have been enabled again automatically, if not enable it yourself.

Then go to [b][u]Display Settings[/u][/b] again and it should look like this now:
[img]http://web.telia.com/~u46218134/multi-monitor-guide-sli/expand-your-desktop.jpg[/img]

You can attach the other monitor(s) now and expand your desktop.

The SLI graphics cards are using the main monitor together, like they should in SLI-mode. And the other graphics card can handle the other two monitor(s).

Im surprised it's letting you do that.

When you use a card with the same driver (Nvidia), it usually takes an effect with everything.

I've had sucess with this, but only with an ATi PCI card. Great job : )

Do you know if you can make it work if you have the third card installed in an x8 slot?
Also, I would assume the third card would have to be at least the same series as the other two, right?

I wouldn't think the card outside of SLI would matter.

Nor would it necessarily have to be of the same series - I remember when people were talking about F.E.A.R.'s method a few months ago with a card from another manufacturer, as with his question above.

I have three WS attached to my two GTSs, and I switch in and out of multi-screen all the time. But I have to switch in and out of SLI all the time to do it (although, with games like Crysis and World in Conflict that gives me the option of using a smaller, crisper screen when I game in 1280*768 rather than the large monitor's 1680*1050).

I have a Compaq with a 6200OC in it that I'm thinking of trying it with. It'll be a couple of days before then, though, because I just finished stripping this rig and reassembling it for lapping the CPU and replacing all the MOBO's heat sink putty, so I'd rather use it for a day or two first.

If no one beats me to it, I'll give you the results.

Hmm...if this works as well as I believe it should from my experiences with this gear, then I may end up buying an 8800 GTS G92 and hook the two smaller WS to that while the two G80s support the bigger screen in SLI...

It dosent matter if it's a PCI-E X8 or X16 slot.

It might not work if the card is not in the same serie. I will try this out right now and come back with the result.

Edit: Tested it with a 7100GS card and it works like a charm. So two series of card from Nvidia is not a problem. Proof added in my post above.

I got problems running DirectX applications but it was on the main monitor and not on the display connected to 7100GS. The image was green like the cable was not connected or some sort of glitch in the drivers. Even when the 7100GS card was disabled this appeared so I removed the card and everything was back to normal. Then I installed the 7100GS once again and now I didn't get the problems I had before. I'm thinking that must I must have screwed something up with my first installation of the card. Maybe the SLI bridge was not fully connected. So I have tested both 3DMark06 and Counter Strike: Source and it works great even with two different series.

It is my belief that once the SLI setup is initialized and complete, Vista is presented the video as a single entity - like the default Single GPU Mode for games that don't recognize SLI. All of the resources are already dedicated to it.

The introduction of the third card to the system from here would simply have Vista working off of two "virtual" displays rather than three literal ones...

You don't need to go through the process after a reboot or lockup. Actually you can't deactivate SLI unless you disable the third card.

Awww, Mod Puppy :-D

And yes, this works, sorta... It's easier with a cheap ATI card in your third PCI-e or in a PCI though, in my opinion... or just fork out the doe, get matched monitors and a TripleHead2Go and forgetaboutit.

- Sorta? What isn't working?
- Easier? This is not hard and takes 3-4 minutes of your time.
- Does it matter if it's a cheap ATI och a cheap Nvidia card?
- Does ATI card work in Windows Vista?
- Using TripleHead2Go is no easier or cheaper than this solution and shouldn't be compared at all. TripleHead2Go is great if you want to use all your monitors in a game, but not as good as this solution if you don't want to.

I'm just curious about what you know and what I have missed.

- Sorta? What isn't working?

- Easier? This is not hard and takes 3-4 minutes of your time.

- Does it matter if it's a cheap ATI och a cheap Nvidia card?

- Does ATI card work in Windows Vista?

You don't need to go through the process after a reboot or lockup. Actually you can't deactivate SLI unless you disable the third card.

Getting "stuck" in SLI and multi-monitor at the same time? Is that really a problem?

Right now, I have the w2007 20" WS LCD in my sig as my main monitor on the primary card. On the second are two WDE LCM-17w7 17" WS LCD EDTV/Monitors. When I use my IDEs, I like to use more than one screen. In fact, there's three things I lean on multi-monitor for that all get waxed when I jump to SLI for gaming or simulations.

I do a lot of this type of work, and would love to be able to keep the main monitor in SLI in order to run some of the test sims while I'm still in the development environment.

And I would particularly like to be able to jump to any of my monitors at will without the constant hassle of dropping into or out of SLI - all dependent on what I want to do.

I can't really see a need to get out of this if I can get into it. I mean, what would be the point? The two monitors that are auxilliary never, whether in or out of SLI, get more than half a card's capabilities. Right now, though, the capabilities of the graphics on the larger monitor definitely change with the state of SLI.

No, I can see no reason to have to jump back and forth if I can use this all the while - otherwise, why would I want multi-monitor SLI in the first place.

So I don't see this as a real problem area.

As to Goddess's response: Ya know, this "throw money at it until it goes away" stance is getting a little tiresome. Some of us want to be able to do more than just spend some money and turn on a switch. If it doesn't suit your lifestyle or choice of operation, so be it.

But whether or not it's useful in your particular case doesn't necessarily detract from its value to others. And it definitely doesn't detract from its validity.

Comments to the thread were supposed to be whether or not it worked so problems with the technique can be identified and hopefully ironed out. Did anything in your post advance that effort, or only heckle it?...
