ATI Eyefinity with 4* TH2go
resulting in 12 * 1280 * 720 ...

xd_nitro 28/03/2011 - 11:28

yeah now that way I'm talking about!

xd_nitro 28/03/2011 - 11:31

i've just spotted that the nVidia590 has 3 DVI outputs, I wonder if that can do 9 screens...

xd_nitro 28/03/2011 - 12:32

also, I see this is at 50Mhz, what can you get running at 60MHz?

MSBERGER 28/03/2011 - 21:41

it is Hz not MHz.

60Hz is also possible of course, the "European 50Hz-thing" most of the time is the more difficult part.


xd_nitro 29/03/2011 - 00:32

oh yeah of course Hz. Mhz would be pretty cool though. :)

so what's the deal with new hi end graphic cards?
regarding performances and compatibility
seems there's still some troubles with some shaders on ATI cards?right?


  • HD5870 2Go Eyefinity 6 + 6 triplehaeds allow in theory a 18 screen setup!
  • GTX 580 Phantom 3Go : more memory (in my case i'ld like to extend the memory for preloading and Queueing textures )but no span mode under win7
  • GTX 590 3Go : dual GPU cards, no span mode, texture sharing is not possible so only one of the 2 unit is used (disabling SLI) does that mean that only the half of the available memory is used too?
robe 29/03/2011 - 17:33

So, my idea was totally wrong...:

I'm going to setup a SLI of two Quadro 2000D on I7, 8bg of ram, win7.

My goal is to manage two projector 1024x768 in stack with one card and 1 monitor for the patch interface on the other card...

Please I need your help.


robe 29/03/2011 - 17:35

PS: warping and keystoning are different on each projector, and I have some video that should be played on each Renderer...(videotexture? or VLC)

xd_nitro 29/03/2011 - 23:06

@circuitb, are you sure there's no span mode on the 590s? I've got one arriving tomorrow specially for spanning.

circuitb 30/03/2011 - 12:39

@ xd span mode is possible but with sli disabled!
dunno what happens to the GPU / shaders performances
how the 3 DVI outputs are managed
and if you still have the 3Go of Ram available
many questions :)let us know your first impressions with your 590

m4d 30/03/2011 - 14:18

@circuitb / xd nitro: as the vram on the board is afaik not shared among the 2 gpu cores, it looks like there'll be 1,5 gb of vram for each gpu core no matter what the application/driver settings are..

xd_nitro 31/03/2011 - 01:44

well there you have it, nVidia590 can't span across it's 3 ports. gutted. I now remember this was the case with the 295! Obvious really considering it two GPUs. Rat bags! ATI here I come.

Oh well, got a nice card for when I'm (rarely) using a single port. hmmmmmmmmmm++++++

xd_nitro 31/03/2011 - 01:45


xd_nitro 31/03/2011 - 20:04

haven't given up on this. The 590 DOES support span across 3 ports in windows 7. Span mode is back in windows 7! It's called Surround 2D. Currently having trouble with another graphics card in the system too. Fingers crossed can get 3 triple heads spanning. Read here about requirements for Surround (2D).

m4d 31/03/2011 - 20:09

ahh, cool :) i forgot about that since my rusty old 260 does not support it.

sunep 31/03/2011 - 21:00

@m4d according to xd's link your (and my) 260 does support surround 2D

xd_nitro 31/03/2011 - 23:40

got a secondary monitor working with it which is nice. So primary 1080p and secondary span of 3840x1024. Needed to install the latests beta drivers though. Trouble with 3 x tripleHead2Go Analogues and digitals but not beaten yet.

xd_nitro 01/04/2011 - 15:52

%100 can't get 3 x 3H2G spanned on the 590 :(
