OK.. my mind just went totaly blank and I wanted to turn this back on but I cannot find the option... the one that is in premiere... any help? thanks...

Project Settings->Playback settings->External Monitoring Device

OK... before I thought it was a check box and you picked a monitor, now its just a drop down. Either I forgot or it changed in the new update of 3.1.1... oh well thanks!

The checkbox/radio button dialog is only if you use Cineform's RT engine in Premiere, they have a different Playback settings box.

Just using the defaults and no extra cineform stuff as I do not have it. It works on my HDV projects but my DV projects do not show the second monitor.... strange...

I have heard that before, but I don't edit DV. I think the workflow they have in mind for that is DV out over firewire to a TV, but I am not sure if that is why.
