The cheap passive glasses and the lack of the annoying flicker typical of the popular active-shutter systems are the two key benefits of the Zalman Trimon ZM-M240W kit.

On the other hand, I wouldn't put this product above the competition for a number of reasons, some of which are due to the very technology of interlaced polarized 3D and others are due to the specific monitor.

First of all, the ZM-M240W has very small vertical viewing angles in 3D mode. When you deflect your eyes from the “right” position by ten degrees or more, the 3D picture gets disrupted. At large angles of viewing there is no difference at all whether you are wearing the glasses or not. This downside is not as critical for a desktop monitor as for a TV-set, yet it must be mentioned.

Second, the very principle of building 3D images in this monitor reduces the matrix’s native resolution of 1920x1080 pixels to 1920x540 pixels in 3D mode.

Third, the monitor itself has a very unassuming exterior design with a lot of black gloss, unhandy controls, and scanty setup options. Such properties are typical of cheap office products rather than home-oriented gaming monitors.

Fourth, some of the monitor's technical parameters are rather poor. For example, it regulates its brightness with the matrix, which has a bad effect on color rendering, and its average response time is over 15 milliseconds. All of this makes the Trimon ZM-M240W less attractive for users who want a modern 3D monitor for games and limits its target audience to people who want to enjoy this particular 3D imaging technology.

I suspect that these downsides are largely the consequence of Zalman’s inability to compete with first-tier brands in a market which is not actually the company's main playground. The sales volumes are obviously small, so Zalman has to keep the manufacturing cost of this monitor low in order to maintain a competitive price. Unfortunately, this way of doing business is but seldom profitable.

On the other hand, the Trimon ZM-M240W may be interesting even as it is, especially for people who want 3D imaging but cannot put up with the 60Hz flicker of the active-shutter glasses. The Trimon offers a viable alternative which is absolutely free from that downside.
