6 x 1024x768 with triple head and quaddro fx?

Hello,
do anyone knows if I can run 6 x 1024x768 75Hz with this config:

Mac Pro 8Core
Nvidea Quadro FX 4500
2 x Triple Head 2 Go Digital

If yes, is the NVidea the onliest card for MAC Pro to make this possible?

Best regards

Not a metter of GPU at all it's all about the HD .

Here I'm sure you can get up to 4 1280x1024 screen output using one TH2G and un Single DVI on a Ati xt1900 .

Then this does not mean you can run such big movies , it all depends on what kind of Hard Disk you have .

Can you provide us a sys profile ?

Ok, don't misunderstand me.

Forget the harddrive for the moment.

With Ati X1900 and 2 TH2G you can run 6 x 800x600 max.
What is with the Nvidea 4500? Can I run 6 x 1024x768 max.

Or can you tell me what is the advantage in using the
NVidea 4500 instead of the ATI1900?

It's not a meter of resolution .

As far I know you can run " TEXTURES " up to 4096x2048 px for every layer . So 14 4096x2048 textures .

This does not mean that you can play 14 x 4096x2048 movies .

I don't think there is a improvement of performance by using NVidea 4500 .
So as far I know , there are no advantage .

-emil- i think he needs lots of outputs - not a big movie.

i do not know whether the nvidia 4500 can run 6x 1024x768-
whether it works or not depends on the graphics card and the graphics card drivers - it has nothing to do with my software.
it is not something i can control.

emil-

i think he is talking about number of outputs -

the x1900 does not like running with 6x1024x768-
the 7300 will do this - just about - but the performance on 7300 is not so good.

its in the graphics card and the graphics card driver - not in my software.

i do not know whether the 4500 will run 2x triple heads.

I personally tested the follow :

One Mac pro 2.66 with 2 giga ram and a ATI RADEON XT 1900 4 sata drive amounted on the internal bays
One TRIPLE head 2 GO DIGITAL EDITION ( very important not the analog edition )
Catalyst m147

I was able to output 4 x 1280x1024 @ 60 HZ ( 4 = 3 on TH2G - 1 on second DVI output )

Also ...

I've personally tested the follow :

Mac 2,66 2 giga ram with ATI RADEON Xt 1900 using TWO triple Head2Go Analog edition allow me to output the follow

6x800x600 @60hz

This is what I had from my system ....

Once an old rich man told me :
One don't know if one don't test

'digital edition' only worked at 60hz last time i checked.

you need to be super careful mixing screen sizes with different sizes on different outputs - because it does not always work and can kill performance.

Thanks for the comments!
My customer decided to buy a ATI X1900 has saw no big advantage in buying the Nvidea4500 which is much more expensive.

He also decided to buy 2 x TH2G digital edition.
It is nice that you can swap the triple head functionality to dual head.
The newest version can output 75Hz in 3072x768 mode.

mac news sites that compared raw graphics performance saw no advantage to the 4500 over x1900. i have not tested them.
there is a big difference between the 7300 and the x1900- the x1900 is much better. ( i just upgraded a theatre show from a 7300 to an x1900 - with a vast improvement )

just because it says the newest triple head will do 75hz at 3072x768- does not mean it will work. you will have to test it for yourself.
and i would not ever recommend that anyone does this on pre-intel machines - they are just not powerful enough.

there is also the vqs-01 which i have been told has been used successfully on shows in london
http://www.datapath.co.uk/vqs01.htm

this has 4 outputs.

Now I see why we have 8 mixes at hand...

The vqs-01 seems to works fine. We used it one a TV show a few weeks ago - not directly connected to the Catalyst but the signal going via SDI to the OB unit and back via SDI to the vqs-01 and the four projectors (they wanted to have live camera feed on the projection as well - so the Catalyst output was keyed in from the OB)

At that time I thought the vqs-01 was a good alternative to the TH2G - though it might be a bit more expensive.
Having a look at the available input resolution I am really missing the 4 x 1024x768 at 50Hz - that would be the one to have as XGA is still the standard resolution of most projectors - it might work with 25Hz when genlocked though.

When I get my hands on the vqs-01 next time I will try to do some testings...

yes it might be possible to use 2 of them- there isnt anything in the software to prevent this - it will depend on the graphics card.

i havent tested them myself yet.

Maximun Texture Resolution still 4096x2048 .

two of those could virtually ( no one tested yet ) give us a huge canvas like 8192 px X 768 px http://forum.skype.com/style_emoticons/skype/rock.png

this does not mean it will be possible to run a movie or a picture that big ( yet )

i managed to playback a movie at 4096x2048 @ 30fps using mtron and apple intermediate codec

how many 4096x768 @Xfps does the mtron play ?

I'll try to get one of these for testing. It seems to be better (more professional) than the TH2G.
I'll let you know.

Hi Andre,

Fischer & Friends have them in rental stock - maybe easier to get on short hand than from the manufacturer.

Great, my next question would be to implement this in Catalyst like the TH2G.

Back to the original point of the thread, I would like to know if anyone has gotten 2 TH2G to output 6 1024x768 on a Quatro FX 4500.
15-11-2007, 09:13 AM
SourceChild

Has anyone gotten two of the vqs-01 to output 8 800 x 600?
What about 8 1024 x 768?

I am a little concerned with the input having to be 25Hz to do 2048 x 1536. Has anyone noticed a problem with this?
