[osg-users] Anyone using OSG in Windows with 3 (or more) monitors on 2 (or more) graphics cards ?

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). David ___ osg-users mailing list osg-users@lists.openscenegraph.org

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. Wojtek - Original Message - From: David Spilling To: OpenSceneGraph Users Sent:

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

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 Hi Robert, Wojtek, I recall a post for Jean-Sebastian Guay in the last couple of months about Vista not supporting

Re: [osg-users] Anyone using OSG in Windows with 3 (or more)monitors on 2 (or more) graphics cards ?

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, I'm not sure what TwinView corresponds to, as it's more of a Linux/X term. 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.

Re: [osg-users] Anyone using OSG in Windows with 3 (or more)monitors on 2 (or more) graphics cards ?

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

Re: [osg-users] Anyone using OSG in Windows with 3 (or more)monitors on 2 (or more) graphics cards ?

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

Re: [osg-users] Anyone using OSG in Windows with 3 (or more)monitors on 2 (or more) graphics cards ?

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. David 2008/6/26 Wojciech Lewandowski [EMAIL PROTECTED]: Thanks, Unfortunately it looks like DirectX only.

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
