Many have asked for Catalyst preview , i personaly think this is just a placebo , btw preview it's here already .

So how to preview content ?

Open Catalyst

Goto fullScreen

Click on layers

On Layers Click on FX On , turn it off if it's Red .

there you go , you can now see what is loaded in the different layers even if the dimmer is off .

In my opinion Catalyst users should always have a companion like a little Mac Book ( just 999 euro )

A Mac book cost like two monitors .

With a mac book it's possible to remote preview content , it's possible to set a remote server using Apple Remote Desktop ( to be turned off during show time ) .

I hope this is helpy .
