No word from Adobe who would know for sure, but...
On a lead from a Premiere Pro CS6 thread that run into missing Playback Settings or grayed out Playback Settings in Premiere Pro CS6 version as well, we tried creating the keyboard shortcut Alt+Shift+P to access a possibily hidden "Playback Settings", no success. (See Premiere Elements 12 Windows 7 or 8 64 bit, Edit Menu/Keyboard Customization/Windows/Monitor Window/Playback Settings.)
At this point, the Playback Settings button in preferences and the Playback Settings choice in the monitor as we knew them in Premiere Elements 11 appear to be gone.
Same problem here. I am very disappointed, since I wanted to use multiple monitors: a huge external monitor (as primary) for editing and the laptop display as player. Maybe it's time to upgrade to Sony Movie Studio
In Premiere Elements 13/13.1, even the grayed out "Playback Settings" seen in 12/12.1 after right clicking the Edit area monitor is no longer there. And, Playback Settings tab does not
exist in Edit Menu/Project Settings/General in 13 (which is the same situation in 12/12.1.
In the meantime I've found the menu Window / Dual Monitor Workspace, which works brilliantly: Now I can use the timeline panel on the 2nd monitor of my dual-monitor extended desktop, while keeping the player/preview panel/window on the laptop display (1st monitor). Absolutely gorgeous. No need to upgrade from PrE 12.
Just a note about the Dual Monitor feature of Premiere Elements 11, 12, and 13....glad that you are finding it a benefit to your projects' workflows. Great news.
But, have you noticed that the feature has a problem remembering the Window Menu/Dual Monitor Workspace?
Very true, ATR. I noticed it immediately, but I was so happy that I can use both my monitors. Actually, I can live with this inconvenience. Normally, I work 1 or 2 hours (sometimes even longer) with one project: moving the timeline panel and resizing it to the full size of the monitor takes about 5 seconds. On the other hand if PrE 13 had solved this issue, that would be another argument to upgrade.
Thank You so much for the information, Miklos
You can do dual monitor still in PE 13 by hitting window and then dual monitor workspace, which basically opens up the timeline in a different window.
