Has anyone here read anything about the possiblity for any Nvidia based card supporting Triple head video like the new Matrox?

I can do triple display now on my computer, but I have to use 3 video cards to do it. I would like to be able to do 3 displays in games (like Matrox's "Suround Gaming"), but no current card supports it.

Any word of a GeForce 4 supporting in the near future or maybe the NV3x?

I haven't heard any rumours to about triple head support. But I don't really see nVidia putting that kind of support into thier low end chips, unless of course the majority of people would like to see it.

What would be nice though is a proper dual head system with separate ramdacs so that you had a true dual screen display. Different resolutions on each monitor and full 3D acceleration as well. That would be nice :)

triple head is a gimmick...
nVidia is not going to support it...
Althought the latest Quadros support up to 4 monitors already...

I don't think that Triple head is a gimmick any more than Video in, or TV out. It is a feature or option that some people can make good use of, but not every one benifits from. 3 monitor gaming might be a gimmick, but 3 desktops can be very useful to some people.

I knew about the some of the Quadro 4s having Quad monitor support, but I don't want to spend $600 for a Video Card.

And that's exactly why you won't see triple monitor support in a pure gaming card from NVIDIA, unless the market dictates this feature be a necessity. I won't deny this feature to be useful for professionals, but those people would be working on Quadros, FireGL's or Parhelias and not GeForces or Radeons.

I'd wager less than half of most computer users, both hardcore and otherwise don't have 2 monitors running simultaneously, much less 3, nor would a great number of these people have both the finances and desktop space to have a triple head setup.

I think wide screen monitors are a better solution than triple head at least for gaming.

I agree and disagree. It's better cause you don't have any seams in your image, but it is not because wide screen monitors are more expensive* and do not have as wide of a view as 3 monitors

*depending on what you are using.

I used to think both dual/tri-head was a gimmick....that is, until I tried it :)

Seriously, I really hope that nVidia explores the possibility of doing a tri-head board. Unfortunately, I have doubts that it will ever happen.

The good thing is the fact that Matrox will probably update Parhelia in the near future, and it would probably be something more in line with what people had hoped it could bring to the table, as far as performance is concerned.

It's a fact that once you start using two or three monitors, you will NEVER
be able to do with less again. I've used dual-head for a long time now,
and it just sucks that's a-symmetric: you want one monitor in the middle
and then symmetrical one left and right.

Of course, all three monitors need to be digital TFT's. I intended to use
three widescreen 20" monitors in my next setup - IF I can find the right
videocard + drivers that is :/

At the moment it's totally unclear if this is at all supported (if I have this
setup - then I insist that all monitors are equally supported in regards to
acceleration. Playing -say- Unreal Tournament 2004 on it should use all
three monitors if I want that). Normally I'll use it for 2D, but still.

How about: in those 5 years nothing has changed and triple head is still not supported?

Probably the Search feature. That'd be my guess. ;)

And apparently no one cared for 5 years. :D Wonder if using the Quadro cards would help? I know our Surveillance team here at the casino uses them. :thumbsup:

Nice, but too small. I want three times 1680x1050.

I think this thread is more current than ever before. Funny to see that people in 2002 thought that 3 displays on a game is a gimmic. Not anymore.

NVidia two monitor span mode is actually useless for most games since the optical axis in just about all games is right in the center of the 3D screen which means just on the seam between two monitors. You can't see where you drive walk or fly.

Using two dual head graphics cards is a solution but now the 3D application needs to share context between the cards which takes time and thus causes low frame rates.

Yet a product like Matrox Triplehead2go deals with that elegantly and people are amazed at the performance. A single card and no context sharing.

I think today the market is very ripe for a triple head card. New cards also should be able to do real-time barrel correction in addition to keystone correction so that the images can be projected undistorted side by side on a curved 180 deg field of view filling screen. LCD projectors have become cheap enough for such setups.

At the very least I expect NVidia to allow to span a 3D context across two graphics cards configured in SLI thus spanning up to 4 monitors.

There a market for a triple head card. With LCD monitors at dirt cheap prices you'd be mad not to run with at least 3 displays all the time. I have been running a system with two 7900GT cards and 3 19" WXGA monitors for over a year and I find a dual screen setup just too cramped.

(Also I want decent stereo drivers back for the NVidia card)

Lol, wow. This thread has been revived twice!!! Now it's 6 years old!!

I highly doubt nvidia will ever make it so you can span across SLI to span 4 monitors....sure that might be great for the 10 people who would use it. It's just not worth their time.

Here's an idea. Get a triplehead2Go thinger, and attach another one to each of the three spots. Now you have a 9 monitor span!!! (I wonder if that would actually work...) Other than of course your video card grinding to a halt from outputting 17280x1200 :D 9 24" widescreens FTW!!!!

Mate, you obviously never ran a 3 screen system. The extra few hundred bucks for the other 2 LCD screens will be the best money you ever spend on your PC setup.

I am just going through steps to have my entire hardware platform replaced. Currently I am running a D960 processor and two 7900GT's and the machine is hired out for a year so I need a new one. Check out my 3 screen simulator videos www.youtube.com/dinther

The next PC will be a Q6700 quad core processor and a single 8800GTX card with the option to add a second 8800GTX in SLI mode. Indeed I am looking at using a Triplehead2GO Digital box this time around. The sad thing is that that box won't do 3 x 1440 x 900 so in desktop mode things will look pretty crappy.

I don't see why NVidia would not allow a 4 monitor span using two cards. Now I spend the money for that second card on Matrox equipment instead.

Palit's got a 9600GT that can do 4 displays, but i'm not sure if you can use all four at one (or even 3).

Don't get me wrong, I would absolutely love a 3 screen system. Right now I have 2 (main 24" widescreen and a little 17" sitting off to the side). But my point is that perhaps it isn't worth it for nvidia if they spend who knows how much on developing spanning over SLI if only very few people actually use it. Really the only games that support multi-monitor spans like you're using are simulators. The majority of gamers are first person shooter or MMORPG players that don't care for more than one monitor because their games don't support it.

First they would need to get dual monitors working with SLI enabled. Right now you can't even have dual monitors with SLI. Even with both monitors attached to the same video card. This is why I'm never going SLI again. Too much of a pain.

Actually the TH2G can't even do 3 x 24" at full res because the bandwidth needed is too much for one port.

No you are wrong have a look here. There are many other uses than professional simulators. Have a look at this list

http://www.matrox.com/graphics/jp/gxm/products/th2go/gaming/list.php

All those games would support a triple monitor span.

As for SLI yeah you are right, it is a poorly thought out architecture. Like with the TripleHead2Go that should sort of be build behind all this SLI stuff and then you'd be right.

This is why I get a single 8800GTX card with the matrox TH2Go

NVidia hasn't caught on to multi monitor gaming. Matrox has done so for a long time with their triple head graphics cards. Pitty those things are so slow.
I am hoping this revived post wakes someone up at NVidia.

Revived for the third time:-)
I have read rumors that new drives should make triple head possible on nvidia cards, anyone knows if this is true?
Of course I mean with full acceleration on all screens.

Reading back my own posts in this thread I need to add that I ended up returning the TH2G device from Matrox because the distortion caused by TH2G was unbearable since it assumes all connected monitors are aligned in the same plane. Instead use two 8800GTS 512 MB cards. This gives me 4 accelerated heads.

However, they can not work as a single monitor in the same way as the TH2G can.

So I further developed my graphics engine and added "Virtual Windows". This feature allows me to place any number of screens at any location and orientation. The engine will ensure that the perspective as seen from the users point of view will be such that all screens appear to act like window panes onto the same 3D world.

Optional a head-tracking device will even allow the observer to move their head thus enabling them to really "look around the corner"

I made this demo video to show what I mean:
