I have Premiere Pro installed on my imac 27inch with an ATI Radeon HD 4850. 'Til yesterday it had been working properly but all of a sudden stop to playing video on my second display. If I go to the "Playback settings", either source or program monitor ones, it seems like PP can't see the display anymore. I did reboot everything, actually several times but nothing worked. Does anyone knows if there's a preference file in the mac's library that can be gone corrupted or any other solution to my issue?
I should say the display is a Philips 241E1 full hd although I don't think that is gonna make any difference. Sometimes I also plug in my Sony Bravia 40inch hdtv through a DVI to HDMI adapter and always PP recognized both.
It didn't happen while performing this operation but just while editing some stuff.
Any suggestion to this is gonna be warmly appreciated, thanks.
Just to give a better picture, I also started a new project with different media but didn't work either.
Ok, just to let you know in case you may encounter the same problem, 5 mins later after I've been writing this post, and after a couple of days was blasting my head off to get this sorted, here it comes the last (but worth) attempt: I decreased the resolution of my main display from 2560X1440 to 1920X1200 and left my secondary display's res to 1920X1080. Then I booted up Premier Pro and.. immediately it worked. So, with PP still on I switched back my main screen res to 2560X1440 and everything went fine. Kinda odd workaround but...
