The technology of producing a volumetric image by means of alternating lines and polarizing eyeglasses is undoubtedly interesting and perspective because it combines simplicity and universalism.

A stereo monitor doesn’t require advanced technologies, clumsy eyeglasses or helmets or even any additional electronics whatsoever. The hardware implementation is most elegant. I guess this solution can just be called beautiful. A small modification of the LCD matrix materials, a simplest pair of eyeglasses – and you get a true 3D picture.

A stereo monitor is no different from an ordinary monitor. VR-helmets have a very low resolution and are impractical for everyday work. Two-colored eyeglasses are incompatible with good color reproduction. The Zalman Trimon, on its part, is just a regular 22-inch monitor in 2D mode, ensuring normal color reproduction, frame rate and resolution all at the same time.

The ability to work in ordinary 2D mode is important for such devices. A VR-helmet has to be bought in addition to a regular monitor, but the Trimon can be bought instead of it! So, the cost of ownership for the Trimon is the difference in price between it and an ordinary 22-inch monitor. At the time of my writing this the Trimon cost about the same money as a VR-helmet. And there is a cheaper, 19-inch version called ZM-M190.

Unfortunately, the new technology is accompanied with drawbacks. First of all, not all games support the 3D stereo mode. It either doesn’t work or works poorly in them. This is not a fundamental problem, though. If Trimon-like solutions take off for real, game developers will have to optimize their projects for them.

Then, the monitor is not ideal in the 2D mode. But nearly all of the problems I found are the same as you can see in ordinary monitors that don’t have any stereo mode. These are setup-related problems of the particular model rather than of the 3D technology in general. It is quite possible to produce a stereo monitor that wouldn’t be inferior to ordinary monitors in terms of its setup quality in the 2D mode. I guess such monitors will be released soon.

The linearity of the image in 2D mode is somewhat alarming as it is directly linked to the interlaced polarizers that enable 3D mode. Hopefully, this problem will be solved as the technology evolves.

I do hope that stereo monitors like the Zalman Trimon ZM-M220W will soon become popular and widely available products.
