I have 3 monitors as part of my setup. My main working monitor, an Asus ProArt P238Q, and a 1080P Television via DVItoHDMI.
They are running off of an Nvidia GeForce GT 120 and a Nvidia GeForce GTX 285.
Before the update I was able to output the screen to my 2 additional monitors via Mercury transmit no problem, one for me and one for the clients. Since the 2014.1.1 update, I can't seem to get playback on my Asus ProArt P238Q.
Had to do some unplugging and replugging in of monitors and finally after toggling off and on the checkboxes for the displays in Video Preview I got it working. Just seems to be really inconsistent when it chooses to engage or not when the preference is toggled.
Hmmm, strangely I had these sorts of problems with 2014. Switching between Premiere and AE would often cause neither to Preview, I would have to toggle on and off all the time or quit and restart, etc. But 2014.1 fixed all that and now it's pretty much flawless.
