My visit at the Genius Bar was rather surprising but conclusive.
- Face Time works perfectly on my Mac Mini, when connected to an Apple Display.
We have also found this thread on the Apple forum, on version 27" of the same monitor:
Need help with a Asus 27" monitor with webcam problem.
The problem is well identified by multiple users and, in their case much more important. The camera is quite useless and renders inoperative any applications that require a camera. Asus has not provided the cameras of these monitors, a driver compatible with the Mac.
My monitor is newer, it seems that improvements have been made and the camera now works correctly on all applications I tested (including Skype, PhotoBoot, MacJournal, Home Inventory) with the exception of Face Time. I find myself so lucky and I resign myself to live without Face Time on this computer.
But a small application, iGlasses, can solve the problem in addition to many other benefits, as long as we agreed to pay $ 20.
