Hi everyone,
Topic says it all. Is anyone using OSG on Windows with 2 or more graphics
boards and more than 3 monitors ? If yes what graphics ? Is this possible with
Linux ?
We got the question from upper level whether it would be possible
(theoretically) to drive 3 or more displays from one
Wojtek,
You could see if SoftTH (http://www.kegetys.net/SoftTH/) works for you - my
colleagues have had some good OpenGL experience with it (although not
specifically with OSG).

Thanks, Unfortunately it looks like DirectX only. Seems that Matrox
TripleHead2Go gives similar effect in hardware spliter. I am loking for the 3
monitor output without aditional tricks.

Hi Wojtek,
I have only experience of doing multi-card multi-display under Linux
and IRIX. In my own Linux machine I've played with two graphics cards
with two outputs, and four outputs. It works just fine once you
configure X11 appropriately. For best performance use twin view so
that you can

Thanks, Linux may be viable option for us. Twinviev may be also a good idea.
I have not tried that, I tried 2 separate displays on 7800 GTX and one on

Hi Robert, Wojtek,
I recall a post for Jean-Sebastian Guay in the last couple of months
about Vista not supporting TwinView, perhaps I mis-read, but this is
what I recall. Perhaps he'll be able to chip in.
I'm not sure what TwinView corresponds to, as it's more of a Linux/X term.
On Windows
Hi Robert J-S,
You are right. I confused TwinView with HorizontalSpan. Since I have XP this
option is available. But does not work either.
Thanks for feedback,
Wojtek

On Windows XP, we used to have the option to have multiple independent
displays (say 2 displays of 1280x1024 - I guess that's TwinView on
Linux?) or one combined display (2560x1024). The latter is called
horizontal span (you can also do vertical span, 1280x2048 for example).
Now, on

Hi Jan,

That's incorrect. Twinview is Nvidia's term for their multi-monitor
support on their GPUs: http://www.nvidia.com/object/feature_twinview.html
Sorry, I just assumed as I hadn't seen the term used on Windows.
Hi Jan,
Thanks for the explanation. I also added to the mix confusing TwinView with
windows HorizontalSpan but it looks like we all were thinking about the same
functionality ;-)
A more common setup is to have two GPUs each driving two screens (not
SLI! That is something else!) and each of
Hi Wojtek,
Thats the configuration I am after. I don't need one continuous desktop
divided into 4 or more monitors. I am looking for the configuration
which would allow me to drive four independnt views from one machine.
You can do that in both setups. If you have one continuous desktop, you
You're right - I got confused between SoftTH and the Matrox box. I think I
remember there being an OpenGL version of SoftTH in the pipeline though, but
not sure what it's status is.

Hi Wojtek,
We use osg on a dual dualcore opteron system running linux fc7 driving
an nVidia QuadroFX 4500x2 with four monitors attached. It works great.
The gfx card is a bit pricey and requires the addition of a G-sync board
to keep it's two gpus in sync (framelocking).
I've tried

I'll be happy to provide more specifics if you want.
Thanks for the info. Its all I need for now. I will ask for more, if we
