The problem I have, is that the signal is not running smoothly.
Then a turn off the preview on screen one, they are running more smoothly, but not good.
It looks like the G5 has much more kraft to run it, Catalyst is only use 17% proc. kraft

Can some one help me with the problem. I think it must be a setup thing in the Catalyst

which g5?
what refresh rates you run your screens?

triple heads on older g5 not recommended at all.
totally overwhelms older graphics cards. pre pci-express.

also different refresh rates with older graphics cards - and triple head- never resolved by graphics drivers.
works ok in intel macs.
