3D monitors haven't really caught on since they were introduced a year ago, mostly due to the lack of choice and also because of its sky-high pricing. When they were first introduced along with Nvidia's 3DVision, the monitors supported a maximum resolution of just 1680x1050 and were priced more than twice the price of standard full HD monitors, so obviously there wasn't a mad rush at the stores.
Today things remain pretty bleak as 3D gaming didn't exactly take off the way Nvidia hoped it would. However, we still see newer 3D monitors cropping up that sport a higher resolution than before and today we have one such monitor from Alienware.
The AW2310 is not new and has been around for quite a while now. It's based on a TN panel with a color gamut of 83% of the NTSC spectrum, nothing great but still better than the regular TN's, which only give you about 72%. The response time is a quick 3ms and packs in a 400 cd/m2 brightness level. Since it supports 3D the refresh rate can go all the way up to 120Hz and what sets this apart is that it's one of the few Full HD 3D monitors currently available in the market.
