Hi all,

I'm setting up a show using two separate Cat systems, each with the following setup:

Output 1: Monitor at 1024x768, 75Hz refresh rate
Output 2: VQS-01 to four projectors, VQS is set at 2048x1536 @ 38Hz refresh rate.

I'd tested it with one machine feeding four wee projectors - all was working - then switched to both machines feeding 8 LCD monitors - at this point four of the screens started to show a nasty interference pattern, and the endless fault finding began. After lots of swapping out cables, switching VQS boxes (the interference stayed with the one particular VQS box) and many reboots and mode switches on the VQS I returned to the original test setup to find the interference was now on the wee projectors too! Argh!

So my question is... wtf?

Or more usefully, does anyone with experience of VQS boxes recognise anything here - my concern is that a fault has developed in the VQS as it initially ran fine to the wee projectors.

Any ideas, advice, pension recommendations welcome.

Best

Tim
