I'm a fan of both 3x monitor set ups, but 3D is a lot cooler. GreghomeIMO, 3D is still not as appealing and no as cheap as Eyefinity or 2D Vision Tri-Screen Gaming. Now that we know how 3D Vision 2 compares to the original, let’s see how it compares to the competition!

On the laptop front, Toshiba plans to offer the Qosmio X770/X775 and Satellite P770/775 with 17.3” 1080p screens incorporating LightBoost technology. Nvidia also lists the Acer HN274HB and BenQ XL2420T/XL2420TX as 3D Vision 2-certified monitors you should expect to see in the near future. We’re testing an Asus VG278H in this piece, a 27” model with a built-in 3D Vision 2 emitter and a bundled pair of new glasses. Moreover, backwards compatibility works like a charm the older 3D Vision glasses enjoy the same benefit from the tighter timings on new displays with LightBoost. Now, we're able to read the keys on our keyboard when using 3D Vision 2 (something that was quite difficult with its predecessor). This makes a huge difference in practice. Everything appears brighter, and that applies both to what’s on the screen and in your environment. 3D Vision 2 exploits the better performance inherent to today’s monitors, allowing the shutters to remain open for longer, meaning your eyes have more time to collect light. This prevents ghosting by giving the monitor time to refresh over the previous frame. The diagram below shows how this works, but in slow motion:ĭuring this process, there’s some overlap time between frames of video where both eyes are covered at the same time. The glasses cover the left eye when the video for the right eye is displayed, and vice versa, alternating back and forth so quickly that you can't perceive that your eye is being covered and uncovered. That's where the shutter glasses come in. this happens at 120 Hz, or 120 times per second (so fast that, to the naked eye, it just looks like there's a blurry double image). It works like this: the television displays a frame of video for the left eye, then a frame of video for the right eye, alternating back and forth.

Stereoscopic 3D requires that each eye sees a separate vantage point, and the method 3D Vision uses to achieve this is called alternate-frame sequencing it's the same method that most modern 120 Hz 3DTV's with battery-powered shutter glasses employ.

That's self explanatory, but the timing issue is a little trickier to describe. Instead of outputting a constant level of brightness, the 3D Vision 2 LED backlight pulses twice as brightly.

LightBoost addresses both issues with a brighter monitor backlight combined with optimized shutter timings. Then, not only is the display difficult to see, but the glasses cut out so much light that it’s difficult to see peripherals like your keyboard in stereoscopic 3D mode. Our biggest complaint about 3D Vision is that it's very dark, forcing you to really keep ambient light under control for the best experience. The main improvement tied to 3D Vision 2 is part of the display, and it’s called Nvidia 3D LightBoost.
