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. I am very annoyed that this is not disclosed on the ViewSonic USA web site, but it _is_ disclosed on the ViewSonic UK/Europe site (found this out after I took delivery and was setting it up).
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. A discussion with Viewsonic tech support acknowledged that there are design or quality issues with the microphone. It is unfortunate to have to return the monitor since the display quality is good.
