I've also been looking for the 3D monitor locally and recently noticed the AOC one too. Digging a little deep revealed that:
The AOC monitor is quite different from traditional 3D monitors so far (In a good way, in my opinion). Traditional 3d TVs and monitors use high refresh rates (around 120 hz) to switch images quickly on screen and then active shutter glasses are required to view these images for the 3D effect. On the other hand, this AOC monitor uses polarising technology (normally used in cinemas for 3D) which means that instead of using higher refresh rates for alternate images, the images are superimposed on the screen using two polarisations and to view these images you would require simple polarising glasses which will filter the images for each eye.
Active shutter glasses are electronic in nature and are quite expensive (official price at Nvidia store is $149 but locally they are still being sold at around 20000/- RS).
Polarising glasses are very cheap (Around 150/- RS) and require no electricity and many people can watch the 3D content on screen at the same time conveniently which would be a very expensive setup using active shutter glasses.

Have you purchased the monitor yet? I am highly inclined towards getting this AOC one and will like to see how is your experience so far, if you did buy this one.
