Dual displays with dual DVI SLI?

[iwearnosox]

So now that the 30" cinema display is gone I'm contemplating adding a second L2335 to compensate. The 6800 GTO's have dual DVI, and they are SLI'ed. Will the second DVI connector on the first card drive a secondary display? When games boot, does one display just go blank?

I'm basically worried the SLI somehow makes the second display unusable. I assume it wouldn't, but then again I assumed SLI worked on widescreen monitors.

The L2335 is 1920x1200 correct?

Each DVI port should be able to handle that with ease..

Or are you asking something different?!?!




EDIT:

Or are you asking if each DVI port from each card will run the game in a "span" across mode?



Not sure what you are asking.

 

[imported_Kensai]

Yes, you'll be able to use the second connector.
The display settings will differ on which monitor goes clunk or if they both stay active.

I'm just asking if there are any anomolies with dual dvi to dual widescreen on an SLI rig. My feeble attempt at avoiding incompatibilities before I leap.

The advice here is priceless. Second monitor arrived, and the answer is no- you cannot use a second monitor to span the desktop in SLI mode.

Yet again SLI sucks.

This should not be a surprise. This was reported by Anandtech waaaaay back in October of last year.
While SLi isn't without its shortcomings in specific areas, researching a technology before you buy into it would be a wise move.

Yes you can. Remember it may not show up immediately because SLI is executed through the drivers.

Additionally to fix the widescreen, unless you are using 3d stereo glasses :roll: , the 73.00's allow for widescreen support.

Make sure the monitors are connected to the same video card also (IIRC that is what you want).

Rollo, having done this before, would probably know much more about this than me, but it is most definitely possible.

Your problem might lie in the fact that you need dual-link DVI to drive such a large display. Make sure that both DVI ports are Dual-Link.

I dont know why you had to say SLI sucks because of this. Because of a flaw that hasn't been fixed yet. Dont be so quick to insult, given the right amount of time these annoyances will work their way out.

That's absurd, that's like saying don't hate the new car they sold you because it's only got three wheels. They're working on the fourth, it may or may not arrive. In my opinion SLI wasn't worthy of being released until these issues were addressed.

According to the Nvidia message boards dual display cannot be done with SLI enabled. I have tried without success. In addition the 73.00 drivers suck, they do not fix the problems for me. I get speckles and noise in all games when using them.

I don't have the Apple cinema, as I said earlier I sold it. This is with a "lowly" HP L2335.

Maybe you should research your purchases to make sure they'll work before plunking down dough. SLI = problems-aplenty and that's been pretty well documented on these boards. Get a single ultra instead of 2 gto's for example...

Dual display doesn't work in SLI. You have to turn off SLI and REBOOT your computer to make dual display work. SLI is not ready for primetime yet. Nvidia and the rest of us thank you for being a beta tester and funding R&D.

Like Naustica said, if you turn sli off, you sghould be able to run dual monitors just like you can with one agp card and one pci card.

Yeah, I'm aware of that, thanks though. I don't feel like rebooting my rig every time I want to do something 3D.

 

[kylebisme]

The whole point of SLI is to combine the power of two cards to drive one display. If you want to run dual displays, simply dissable SLI.

Again, this is not anything new. EVERY SINGLE review (or preview) of SLi has reported that this will not work all the way back to when they paper launched it over 8 months ago.

This should come as no surprise at all...... it would be like complaining that you can't SLi an FX 5950u with your 6800GT.

 

[rise]

why would you buy a car with 3 wheels ?

 

[fstime]

I like how people defend SLi.

 

[Chode Messiah]

If you run sli with two monitors, it isn't SLi anymore. All ur doing is getting 6800gto performance on 2 monitors. SLi was designed for single monitor performance. That's why I have a better computer than u.:shocked: J/k seriously though, it might just be a problem with those gto cards cause Ive heard they have a lot of problems in SLi. That's why dell is gay. Propriatary sh1t sucks. I got an old dell my friend didn't want and the agp slot was ripped out! just sell the gtos and get an ultra. That or you can run sli on that albatron 48" monitor.:thumbsup:

Well it is easy to defend it agasint such an absurd complaint.

And for someone who proports to be intelligent and knowledgable, I find it massively amusing this thread even exists. I think it was an opportunity (or an attempt at) to throw stones at nVidia.

Toddle your little ATi fanboi asses elsewhere, and when you find you have the same results with their solution, the rest of us will laugh at you.

 

[Ackmed]

Neither of the two you quoted started this thread, so why is it amusing this thread exists? Neither of them made it.

It is too bad SLI cant do this without rebooting. That would be very annoying.

 

[kylebisme]

SLI cannot do it at all, the rebooting is nessacary to dissable SLI just like rebooting is nessacary to change drivers for just about anything or to dissable fastwrites and such.

You're a little paranoid- You're the only one to mention ATI in this thread. I could care less who makes my hardware, I only care that it works.

This thread exists because the hardware that I own doesn't function the way I would like it to. You seem to have a real problem with people expressing their opinions when they don't mirror your own. Instead of adding value you drop in, piss all over the place and pet your ego like it's mister bigglesworth.

The only "fanboi" I see here is you.

The "of course it can't be done, it's Nvidia SLI" in your subtitle does make it sound like you have some bias, and this is comming from a guy who tends to perffer ATI hardware.

Well SLI is an Nvidia trademark. I could complain about a Big Mac without mentioning McDonalds but it's ostensibly the same.
