Having problems with Triple Head to Go

[samsc]

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.

old old computer.

you are pushing it way too hard.

the computer is actually telling you something - you need to listen to it...

I am able to get one of them to go, but can not get them both going

this means this computer and/or graphics card cannot do this - end of story...
