i wish i had seen this post earlier...no response means 'no' i think...
reason why is purchased the ASUS monitor with the webcam, not thinking about compatibility issues. (well, the monitor with the webcam was only $20 more than the one without, so i went ahead and bought the one with the wcam.)
so, to answer your question, No, it doesn't work. i haven't found any information about software or settings to get the webcam to work, and actually, the Asus site says nothing about it possibly working.
BUT! the monitor is beautiful! and i really love the way the screen looks! it has settings for game, theater, standard, scenery...and color noticeably translates differently with each setting.
for the price, it's a great monitor--i haven't found a price like this for any 25.5" monitor anywhere.
but, maybe don't by the webcam version w/o more research. why pay the extra $20 if you don't need to? i use parallels and have window installed so i may try and install the software that came with the monitor so that i can use the wcam. i'm not sure yet.
but, despite the camera issue, i'm happy with my monitor.
hope this helps you...or someone...
oh, and if anyone finds something that may help me use the webcam on this monitor, please post to let me know.
