Just bought 2 Triple Head to Go's and am having problems getting them both up and running to get six screens. I am able to get one of them to go, but can not get them both going. I have a G5 dual core with an ATI Raedon 9800 XT video card. The G5 is running OS 10.4.8 with Cat 4.06. Any suggestions.

What resolution do you want to have ?
your GPU have just 256 vram .... http://www.sinapsi.us/forum/images/u...106-crying.gif sad but true it's not enough .....
buy an other faster GPU ... sorry but I think there are not other thing to do http://www.sinapsi.us/forum/images/u...106-crying.gifQuote:

Btw if you consider the cost of catalyst per output you save money anyway .
I've pesonally test a :
NVIDIA GeForce 7300 GT 256MB (DVI single-link/DVI dual-link)
on a Mac pro
and I was able to run 6 x 800 x 600 .
I 've test a g5 ( don't remember GPU model , it's the standard HES )
I was not able to use two TH2G .
also if I set the TH2G to 3x 1024x768 catalyst can't run , ( send to full screen remain all black , I think this is all about openGL stuff . )
Mac osX was able to see 3x 1280x1024 , but once lunch cat at full screen nothing happen . same for 3x 1024x768 .
some one told me once :
"one never knows until one tests..."
E
I just finished running a show with 2 TH2Gs. Both outputs are running at 3x1024x768. I'll post a pdf profile if it will help identify hardware setups that work.

With my triple head to go, I have 4 screens. The center two are a panorama, I am having trouble getting rid of the seams where the two images meet.
Here is what I am using: 1x Cat 4.06, 1x triple head to go, 4x 5k projectors,
My show is this Monday 3/19
have you ever tried this sort of thing before?
what settings are you using?
what is your projection geometry like?
I tried it when it was still in beta and could not get rid of the seam.Quote:

settings? all of them that relate to what you are trying to doQuote:

Do you understand what this does?
Flat screens or curved?
There are many many many things with doing this stuff.
What do you see?

Right now I am trying to do a mock up, I do not load in till Sunday. I have a through of 18' 6". I am Rear Projection onto flat screen. 4 projectors total. Two outside do not blend. The two inside are blended to make a 10'x 30' panorama.
I have my blend set at 10%. With the blending HUD, I lined up the magenta bars so they are close, but I am having a hard time getting them dead on.
I have my two mixes set so that layer 1 is active on both screens.
My images do not meet correctly. If I move my mixes so that they match up at the screen, then the blend is bad.
try a bigger blend for a start - 15% or 20%
What is the black level light output from the projectors?
Feed them a black input signal - dont need catalyst, and overlap the projectors outputs, what do you see?
This gives you an indication of the black level leak.
If this is noticeable - you might have a hard time.
Are your projectors DLP or LCD?
sorry about the delay, I got pulled away.Quote:

What is black level leak? I do have some dead screen area on the top of both projectors, is that what you mean?
I have 2 of the same projector: Proxima LCD 6860.
black level- projectors even when displaying black input - output light - and particularliy lcd ( this is defined through the contrast ratio )
turn the lights off, leave the projectors on, make them both display a black video input, points the projectors at the same wall, and make the outputs overlap-
what do you see?
---
2' is not a very useful measurement - as any distance overlap depends on image size, and i dont know those things.
I stayed late last night and got everything figured out. The blend looks great at 10%, then I have to use 2 layers to get one image by off-setting the images on the x- axis. This way is going to eat through layers.
Thanks for you help.

so you only need one layer.
this way you use the 'mix x-offset' per submix
I'm sure you did not use ATI RADEON 1900 XT .Quote:

I bought two th2g's as well hoping i'd be able to run 6 screens, i was not!
I have a quad core intel mac with a xt1900 video card, it runs 3 outputs fine on one th2g 3072 x 768 but when the 2nd th2g goes on there i cannot select a th2g see the th2g resolution for that output. I tried running the first th2g at a much lower res but didn't make a difference, does anyone have a graphics card they can suggest that would make this all work?
p.s.
They are analogue th2g's
strange .... i'm in a show right now using two triple for a total of 6 800x600Quote:

can you connect your mac pro to internet ?
do you have an ichat account ?
Can you post the system profile ?
Am in japan with show at mo, will try it again when i get back, what software version are you running?

Can you post YOUR profile - Are the TH2G Analogue or DigitalQuote:

What Graphics card did you use to get 6 outputs with 2 TH2G - have you done a firmware upgrade on it - what firmware version?
Which particular Mac Pro 2007 or 2008?
Did you have to configure 1 at a time or did both work straight away?
Were you running Tiger or Leopard when you had it working?

Using analog or digital TH2G on 1st Gen MacPro with x1900 I can output 6 screens at 800x600.
Using analog or digital TH2G on 1st Gen MacPro with Quatro FX 4500 I can output 6 screens at 1024x768 and 1280x1024
Thanks for the replies - I;ve had trouble in the past with TH2G-D on a 2007 running tiger and an X1900XT.
I'm going to try different configs over the next 2 weeks and will feedback.
