yes - it normally works at 2400x600- 60HZ-

it doesnt seem to work at 1024x768 - 75Hz-

there didnt seem to be a way to do 75Hz ... with the TH2G resolutions available.
so its not that much use in europe-


also my performance testing has shown some restrictions with content sizes and overall graphics throughput.

30Hz needs more ooooomph, more frames per second need to be rendered.

it doesnt seem to work at 1024x768 -

Never had that in this sys config

[samsc]

Never had that in this sys config

what do you mean?

[emilianomorgia]

what do you mean?

Some one said he can get 3x 1024x768 out of the Xt1900 , with my system I never had that working

the systems listed before it never run 6 x 1024x768

Richard brings up a good point. Don't follow my bad example of hacking the OS. Not even I get reliable results.

For TH2G and DH2G there is a fundamental stopping point.
Don't try to run more than 4 outputs with Catalyst.
Either use a single TH2G and a single second output or use 2 DH2G for 4 outputs.

Yes theres a stopping point - for 1024x768 'Don't try to run more than 4 outputs with Catalyst' - true

Think we coud go round in circles here -

Theres no hard and fast rule. - except: test what you want to do before you need to do it!

I've had 6 x 800x600 running fine 1st go on an X1900XT in a 2007 MacPro running tiger. with 2 x TH2G

Also had 4 x 1024x768 from 2 x DH2G on the same spec...

TEST , try, test and make sure you can repeat it....
