How do I set up an external NEC Monitor in extended desktop mode?

Below is a response I got to a query about shutting off the display on my IMac because of not having workspace to view both monitors - I have created the space and am asking for help in how to set it up as suggested below....

Normally people who bought an extra display would run both of them simultaneously, in extended desktop mode. The NEC display might display photo content, while the iMac screen displayed tool palettes and browser windows, for instance.


I would like to have the image I am working on in Lightroom be displayed on the NEC display and the sliders, tools, etc be on the IMac screen

Thanks,

Bob

Re: How do I set up an external NEC Monitor in extended desktop mode?

I use a similar configuration, but with Aperture.

Assuming you have the cables and adapters to connect your NEC to the Mini Displayport or Thunderbolt port on your iMac, it should be as simply connecting the cables, and Mac should recognize the external display automatically - if not click on "Displays" in System Preferences, and you should be able to set up the external monitor from there.

If Lightroom doesn't show the image and the sliders on the monitor you want, and you can't configure that from Lightroom, then use the above mentioned System Preferences:: Display window to set the external (NEC) monitor as your primary monitor.

Lightroom manages two displays itself once they are attached to the Mac and recognised and configured by OS X using OS X System Preferences. Set the monitor you want with your panels, etc., on as the main monitor by launching Lightroom from the dock on that monitor.

Once you have launched Lightroom, then under Window menu in Lightroom is where you can see Secondary Display. Set those menu options how you want in terms of Loupe, etc.. and that view will now appear on the secondary display. Lightroom remembers the layout you want when you quit and restart. You can't move individual Lightroom module sub panels around across displays though, and there are other limitations like Slideshow and Soft-proofing only use the main display and not the secondary.

For general use, just connect the external monitor (and switch it on), then go to System Preferences -> Display, select the Arrangement tab, ensure the 'Mirror Displays' option is unchecked, arrange the two monitors by dragging their depictions and finally drag the menu bar therein (the thin white bar in that blue depiction of a monitor) to the monitor on which you want to have it (which is then the primary monitor for the OS).

For single window applications like Lightroom, you are somewhat at the mercy of what options their developers included. To my knowledge, one cannot detach any element of the UI (eg, the adjustments panel) to a separate window with LR. It, however, has extra controls for what one can separate out to a second display (eg, the Grid or Compare view). The only way to move the adjustment tools to a second window is by just making the whole LR window stretch over to the second monitor such that the adjustment panel shows up on the other monitor (but this doesn't work in fullscreen mode, Aperture with its HUD approach makes it easier to move all sorts of controls to another monitor).
