tearing issues mentioned here might have been fixed if the ATI Displays control panel gets installed.

Interesting you should say that.

I just did a show this week using 2 Catalysts outputting to 4 screens.

I have updated software and the ATI panels on both machines as per the recommended spec.

At various times through the night I had the same tearing back. I tried switching the ATI panel back to default on both machines and fiddled with some of the other settings
but to no avail.

Both machines exhibited the problem at some point during the night.

Yesterday I set everything up and ran the same show to try and establish where the problem was.

I initially thought it might be the card not coping with dual output. However the tearing appeared on a single output playing only a single file. But then I minimised the window to look at the Catalyst settings and I noticed that the tearing was still happening inside the output window.

Just to try something I switched the disc function from Fast (I have Raptors) to Slow. Problem appeared to be fixed. I ran all of the show from the previous night and the tearing did not appear.

What does the Disc function actually do. Am I limiting performance if I run in Slow mode?

you need to look at the statistics HUD and note down the graphics percentage and movie percentage.

which graphics card are you using?
what os do you have installed?
what compression where you using with your files?

what resolution was your output screens?
what projection devices where you connected to?
and running at what refresh rate?

something does not appear to be setup correctly ?



the 'speed' setting affects a very low level graphics settings, that is way below anything i can do anything about.

depending on what graphics card you are using-

you might also have to install the latest display drivers, and possible firmware-

you can get this from

which graphics card are you using?

- ATI 9800 (Apple OEM)

what os do you have installed?

- 10.3.8

what compression where you using with your files?

- Photo JPEG @ 75% or DV PAL

Everything is stable when I switch to Slow Disc Mode.
