I recently saw a post on Inside Aperture where the author showed a photo of his setup. As you can see, he had his workflow set up on the laptop screen and had a full screen preview on the extra screen. I thought I would do the same, then post a tutorial on how to do it. So without further adieu…
Detect Displays
The first thing you have to do when you plug an extra monitor into your computer is detect displays. You do this inside the System Preferences under the Displays section. You might also need to set the resolution of the extra monitor.
Aperture Settings
Open Aperture and select a photo.
In the bottom right hand corner of your workflow, you should see a little icon that looks like a computer monitor. When you click on it you should see a list of view options.
Choose Show Multiple for the Primary Viewer, and choose Mirror for the Secondary Viewer.
You should now see a full screen version of your selected photo on your secondary monitor.
This is extremely useful because you can see the changes that you are making up close and full screen. It also helps when comparing photos.
Try switching the view modes around to achieve different results.
