Early 3D monitor from Zalman drops in price

In May 2008, we tested the first 22'' 3D monitor, the Zalman M220W, which back then sold for over £500.  This year has seen the arrival of the Samsung 2233rz, which is much more responsive and creates a more impressive 3D effect--but for a price, as you need to buy some very expensive Nvidia glasses to go with it.  At the same time, the Zalman model has fallen out of fashion and its price has dropped too:

In the test itself, we wondered whether or not there was a better way of producing 3D than Zalman's.  Today, the answer is definitely yes, but comes at the cost of buying a monitor, 3D glasses and a special Nvidia 3D graphics card that can simultaneously produce two 60 Hz video feeds at 1680 x 1050 pixels, one for each eye.

With Zalman's monitor, though, the glasses are included and the system still works in 60 Hz, but each frame contains half as many lines, as they're interlaced between the picture sent to the left and right eye, producing a resolution of 1680 x 525 pixels.  It also works as a traditional 2D screen, this time at 1680 x 1050 pixels at 60 Hz.
