A common occurrence on photo sets is to be running multiple monitors; for the AD, client, stylist, etc. Another common occurrence is not being able to see all of those extra monitors and it's difficult to work when you can't see the display.
Another digital tech, Josh Marrah, had the original idea and asked if I might be able to build an app to let you monitor you monitors. A little bit of playing around with some low-level system APIs and ScreeningRoom was born.
ScreeningRoom lives in your menubar and give you an easy way to glance at all your connected displays, matching their physical layout. You can also create separate windows for any given display for more active monitoring.
It's out now and just $25 with a two-week trial.
