Thanks Richard

email and instructions received -

Just re-built the Mac with the default Disk image I use and then installed the drivers and updated version of catalyst...... Tested with all 4 inputs - all works fine... I'm impressed to see 4 inputs working well on our DP G5 macs.

For reference - this is a 2.7G DP G5 with 1G Ram and an ATI X800 graphics card. - seems to work fine - cant see any tearing or any image issues at all.

Cheers

Simon
