For black brightness the average and maximum are 5. The monitor is average in this respect. You can note that the bottom of the screen is brighter than the rest of it on a black background.

The gamma curves are acceptable. They differ somewhat from each other and go lower than the theoretical curve for gamma 2. The gamma curves are nearly horizontal at the beginning of the diagram. So again, I do not recommend you to change the Brightness setting of this monitor at all. For an unclear reason, the color temperature settings are available for analog connection only. Besides a user-defined mode, there are three modes, none of which is satisfactory.

The image is rather cold even in the Reddish mode while the temperature dispersion amounts to a few thousand degrees Kelvin. To improve this I decided to set the monitor up manually using the showings of my DataColor Spyder 3 Elite calibrator. This produced a better result as you can see in the User column of the table above. But again, you can only use this setting when the monitor is connected via its analog interface.

When put on the CIE diagram, the points of gray betray the same drawback: the image is too cold and there is a big difference between the temperatures of white and gray. The maximum brightness is nits, which is somewhat lower than the range of nits specified by Zalman. The Max column shows why changing the brightness of the screen with the matrix is bad: black becomes gray and the contrast ratio drops to a funny value.

The User column shows the brightness and contrast ratio values I obtained when I had set the monitor up manually as described above for more accurate color reproduction. Besides the manual settings, the monitor offers five preset modes you can select with the MWE button without entering the onscreen menu.

The modes all have a similar level of white but I have to say that you need a brightness of nits, not nits and higher, for working with text. The level of black is too high in the Movie and Smooth modes, affecting the contrast ratio negatively. The Game mode lacks lights and has oversaturated green. The resulting picture is bright and vivid but has nothing to do with accurate color reproduction. The Movie mode is even worse: about one third of all greens are lost.

You are likely to see a green smudge instead of a green field in movies. And there will be fuzzy spots in the sky instead of cirrus clouds. Besides, the contrast ratio is very low in this mode while darks become light and whitish. Blue is the only color that is displayed properly in the Sports mode.

Red and green reach the top of the diagram too soon, betraying the loss of light halftones. The Smooth mode is hardly any different than Movie. It has whitish darks and oversaturated lights. Clouds become white smudges, and grass is a green smudge, etc. So, the factory-set modes of the ZM-MW are impractical as they distort color reproduction greatly.

And if you need a higher brightness in games or movies, you can switch into the Text mode. This is a normal speed for a TN matrix without response time compensation but it is too slow in comparison with RTC-enabled matrixes. Besides, it has two technological drawbacks: the conspicuous inter-pixel horizontal lines and the locking of the color temperature setting for DVI connection.

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. 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 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 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, inch version called ZM-M Unfortunately, the new technology is accompanied with drawbacks. First of all, not all games support the 3D stereo mode. 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. These are setup-related problems of the particular model rather than of the 3D technology in general. 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-MW will soon become popular and widely available products. The market for small fingertip mice has been stale for quite a while with most mice being quite big and unruly for this specific grip style.

If you are the type of person that likes to listen to music on the go a lot, you might have noticed that the best experience while being out and about is most likely offered by in-ear buds. This is because not only do they whisper directly into your brain, they also form a tight […].

Finding a truly great mousepad has become pretty boring lately because you can answer all questions with — just buy an Artisan. In itself, this answer is actually a good one, but if you have a more adventurous spirit just buying a bunch of Artisan pads is quite anti-climatic.

We have always been fans of […]. Out of all the business webcams that Logitech offers, the Logitech Brio is known as one of the best and most promising models to date. Each feature that this webcam offers is quite rewarding and makes it really hard to complain about. All of us are looking for our end-game mouse. In this pursuit, the saddest thing that can happen to mouse enthusiasts is to find a product that fits their grip style and hand size perfectly but to discover that it lacks features.

The main feature that is often missing from such mice with end-game potential […]. It is no secret that the future of the gaming mouse industry is wireless. Although paracord cables are quite nice, nothing gets quite as close as true wireless freedom. The effect works by using polarising filters -- such as used in sunglasses -- for each alternating line of pixels. Each line corresponds to one or other of the lenses, and this in turn creates a stereo image.

While it sounds tricky, what it means is that there's no need for clunky headsets or blue and red cellophane -- just a pair of slimline glasses.

Zalman have thoughtfully included two sets of glasses in the package: one a fairly nerdy looking pair of sunglasses and the other an even nerdier pair of clip-ons. However, there are several caveats to getting the stereo glasses working. Second, the application needs to support it. The other specifications are fairly similar to models we've seen before: contrast ratio, 5ms response rate and a small set of 2W speakers behind the bezel -- blink and you'll miss them.

Gaming is a blast, and though the black levels aren't as deep as some monitors we've seen it doesn't seem to hinder performance at all. DVD watching was also good, and the x resolution gives more than enough real estate for most media. Colour reproduction was good even though uniformity wasn't the best with greys and blacks in particular appearing patchy and not consistent from end to end. Also, and on a minor note, alternating strips of the polarising filter are visible at a normal viewing distance.

They appear as a series of horizontal lines -- similar to what you'd see on a CRT monitor, only a little fainter. This didn't affect normal usage. But it's the monitor's 3D capabilities you want to know about right? But 3D methods have come a long way since the dark days of nausea and paracetamol after five minutes of viewing, and the ZM-MW actually managed to impress us. Thus, unlike the old alternative method with its rapidly alternating frames, this technology is smooth and flicker free.

And once Zalman left it with us, there were no problems keeping the experience going. The secret, it seems, is to find the right eye level and stay there; left and right movement is fine, but lift or lower your eyes by mere centimetres and the image will blur. Still, the 3D effect is perfectly visible from a wide range of angles, as long as that all-important eye level is met.

But how effective is it?
