Summary: My family has purchased four ViewSonic monitors, and have been impressed with the quality. However, I am disappointed with this purchase. I will probably return it. 1) The webcam works, but the microphone is not compatible with my Macintosh computer.
Summary: The webcam is fair - speaker audio is fair to poor - and the microphone is very low output with poor sensitivity. An inexpensive microphone connected to the same port works great so it is definitely the microphone in the monitor.
