M329+FX4000 quadro problem

[samsc]

i have tray whit 2400x 600,3072x768,3840x1024. Display port whitout triple head work ,i have try also triple head dvi whit adapter active displayport to dvi dual link , but resolution max for primary out is 2400x 600 second machine have 1 monitor for preview and 1 triple head DVI AT 3840X1024 for 3 screen and work well.I dont wont cut the big screen led 3660x1360 on two machine .

have you been able to get the display port triple head to work at any resolution?

have you been able to get the display port triple head to work at any resolution?

what settings are you using in the matrox powerdesk GXM control panel?

Have you checked matrox technical support about using 2 different types of triple head at the same time?

--

you need 4.5M pixels - there are other configurations that might work?
3 * 1920 * 1080 from a single triple head ( if this is possible ) ?

You will probably need more than one Catalyst machine to accomplish this.
I would recommend (x2) servers, each with a single TH2G and local monitor.

The spec NVIDIA lists for this card very clearly shows the maximum resolution to be: 2560x1600 @ 60Hz
http://www.nvidia.com/object/product...00-mac-us.html

Todd is correct in stating that the general rule is to not use more than one TH2G per machine or two DH2G.
Unless you are running at vey low resolution (x2) TH2G will most likely give you problems.

Hope this helps.

For single led screen much better to use one computer

He needs 4.5mega pixels which can be done with 3x1920x1080
Doesn't need 6 outputs as such

I don't believe any nvidia output max of 2500x1600 is relevant in these situations
Otherwise no large triple head outputs would ever work and larger resolutions than this do work

Agreed one machine is always better if possible.

My understanding of how the TH2G boxes work is that they essesntially tell the video card what the total size of the "canvas" (raster) is, and then the TH2G cuts that "canvas" (raster) up accordingly. Am I correct? Or have I misunderstood the process somewhere?

My point was that anytime you step outside of the spec for any piece of gear you are in uncharted territory and cannot expect everything to go smoothly.....it might work or it might not. Results may vary widely.

thats correct - the pixel canvas is cut up-

the graphics card will only change to the screen resolution if it can- so its not uncharted as such -as it wont do something it cant-


the triple head uses an edid setting to tell the graphics card what size of screen its connected to-


also there is another thing to do with the bandwidth of dvi and display port connectors- and what the maximum pixel clock speed is- this is the main limit-

Richard hello sorry for the delay, I installed a GTX 285 version (windows bios) card instead of 4000 for the big picture with 6 LED outputs to 1280 x 1024, the measure of the total mixes is 6x1120x760 each, the machine is very good, not sin to use the card quadro 4000 with 2 triple head . I added a twin machine with geforce gt 8800per backup. As soon as I send you photos of the large LED. Thanks to all for your support, the other machine with the card quadroon 4000 with a single dvi triple head is very good, the machines are used x the festival of Italian song (San Remo) I forgot ,I have 2 ati 5870 cards on the shelf, nothing new from the ati?

hi Richard, the technical guide says you can not use two different types of triple head under windows, but no restriction for mac user. yesterday i have update triple head DP whit software matrox but nothing change.in matrox power desk i have standard setting. I will try to use old catalyst quad core 3 ghz whit ge force 8800 for six out if possibile

Can you get anything at all out from display port? With triple head

Start with a only single screen
Then add another

You should also look at the datapath x4

Which does 4 completely configurable outputs unto 4x1080p30 on each dvi port
And doesn't have the same restrictions of triple head
