In a room much too dark to use my iPhone camera to take decent pictures (my main camera's battery died and I could not find a charger) Viewsonic showed off its answer (or perhaps question depending on which began conception first) to Samsung's 22-inch SyncMaster 2233RZ, the 22-inch Viewsonic FuHzion VX2265wm.
Like the Samsung, the FuHzion has a 120Hz refresh rate. This is double what a typical monitor has. The 120Hz refresh rate allows the monitor to display a stereoscopic image. Once you put the "3D" glasses on, games on the screen will appear to have a deeper perceivable depth.
To get it to work, you'll need a Nvidia GeForce 8, 9 or 10 series card, the glasses--$199 separate or bundled with the display in a package deal (no price available yet). Other features of the monitor include a 1,680x1,050 resolution and built-in speakers.
I've now had the opportunity to test out both the Samsung and the Viewsonic and from what I could tell (I was not able to do a side by side comparison with the same game yet) they performed identically.
So we'll have to wait a few months before I can get both of these suckers in the lab and put them through the ringer. The FuHzion will have a MSRP of $349.
