Hothardware published a review of the Asus PG221 22 inch LCD Monitor. The Asus PG221 sells for $545.61 on Amazon.com.

Quote from the review: "As its name suggests, the PG221 is a 22.1” monitor. It has a widescreen 16:10 aspect ratio, a built-in 1.3MP webcam and speakers – including a subwoofer – and a bevy of input options. The PG221 has a high contrast glare-type panel coating as well, for better saturation and color density.
If you look at its individual features, the PG221 seems like a winner. But we dig deeper to see if the PG221’s overall performance equals the sum of its parts."
