On Amazon the BenQ XL2420G is $540, or $529 from B&H Photo, not inexpensive but within the grasp of more people than some of the larger and more expensive G-SYNC monitors. It has a maximum refresh rate of 144Hz as you expect from this style of monitor and it does indeed support Nvidia's 3D Vision, although some may be deterred by the 1080p resolution and the fact that it is a TN panel. Some features do need to be sacrificed to bring the price down and the simple fact is that there are no IPS G-SYNC monitors currently for sale and TN is the faster type of monitor and this display is all about speed. The Tech Report tried it out and were very impressed, check the full review to see why.
"Today, we're turning our attention to BenQ's XL2420G, a 24" G-Sync monitor that's currently selling for about $580 at Newegg. This display is a little smaller and more affordable than some of the other G-Sync offerings we've looked at, but it's not lacking in functionality or connectivity. Quite the opposite."
