HP 2311 gt | Entry-level polarization stereoscopy
Today we are talking about stereoscopic 3D, which can be found in the living rooms of wealthy citizens and in the multi-display stands of our laboratory. Judging by offices around the world, we can see that this technology is taking root here. But outside of our laboratories, the number of friends and acquaintances who are planning to buy 3D can be counted on one hand.
We're not at all surprised that stereoscopic 3D technology hasn't become as popular as manufacturers had hoped. Prices for screens, reasonably powerful graphics cards, and active shutter glasses are still quite high. And if you are not amazed by what you see on the screen, then there is no reason to fork out significant sums.
However, we try to keep up with the times. We originally published the first introduction to Blu-ray 3D on PC, and more recently delved into a thorough comparison 3D Vision from Nvidia and HD3D from AMD. However, so far we haven't touched on the two most popular stereoscopic 3D technologies: active shutter systems and polarizing passive systems.
When Hewlett-Packard told us they wanted to send us their new monitor HP 2311 gt For this review, we had the opportunity to evaluate HP's products and compare the passive solution with the 120Hz active display we've used previously.
HP 2311 GT 3D Monitor
Over a year ago we released a review of the HP 2311x monitor "Three-Way 23" LED LCD Roundup: Dell, HP, And Samsung". The budget 23-inch TN LCD had a native resolution of 1920x1080, plastic case, and the possibility of easy connection was provided by perpendicularly located connectors on the back of the monitor.
HP 2311 gt modeled after the 2311x, which suggests that HP 2311 gt aimed at entry-level consumers. And its price is proof of this: at the time of writing the review, it cost about 11.5 thousand rubles. This is one of the lowest prices we've seen for a 3D monitor.
For that price, you'll get a body similar to the HP 2311x - they're both plastic and lightweight, with a molded base that doesn't allow you to change the height or rotate the LCD panel. The tilt can be set anywhere from 90 to 65 degrees from the table (tilt is a critical setting for Film-type Patterned Retarder 3D technology, but we'll talk about that later). Despite the limited adjustments, the monitor is quite stable.
In our opinion, the perpendicular arrangement of the HDMI, DVI and VGA connectors on the monitor HP 2311 gt makes them easily accessible and easy to connect. But, it will interfere when mounting the monitor on a wall, although this model doesn't imply that, so it's not a problem.
Navigation through the main menu is carried out using four buttons in the lower right corner of the monitor. It includes basic settings contrast and brightness, but provides more fine settings color management, where you can adjust the levels of red, green and blue. It is also good. According to the Spyder 2 Pro calibration utility, our sample high level blue and green, which is why we received a recommendation to set the colors to R255, G195 and B160.
Included with monitor HP 2311 gt you will find the power adapter and cord, hdmi cable about 1.8 m long and a CD with documentation and software. This disc includes the CyberLink PowerDVD media player for playing Blu-ray 3D and outputting DVD video in 3D mode, as well as the TriDef 3D program for running games in stereoscopic mode. That's all you need to watch videos and games in stereo, except for the content itself, of course. Naturally, it also contains other components, such as the monitor driver, the HP template configuration utility and 25 3D demo photographs.
In addition, the box contains two pairs of passive FPR glasses with protective covers and a cleaning cloth. It is important to note that these lightweight, simple and cheap polarized glasses are strong point passive 3D displays. HP 2311 gt also works with RealD 3D glasses, which you might see in movie theaters, and LG FPR 3D brand glasses.

HP 2311 gt | 3D display technologies
Regardless of the display you're using, stereoscopic 3D technology sends each eye a different image, presenting them with two different perspectives. Your brain connects them and creates the effect of depth.
There are currently only two commercially successful 3D display technologies available to PC users: active shutter systems, which use an alternate frame sequence in which images are blocked alternately between one eye and the other. And passive systems with circular polarization, which allow you to tilt your head and still maintain left/right eye separation. To achieve stereoscopy, HP uses circular polarization technology, or FPR (short for film-type patterned retarder).
We discussed the basic concepts of active and passive systems in the review "Games in stereoscopic 3D on the entire wall: building a home theater on two polarized projectors" in 2010 year. However, for today's article, it makes sense to revisit the most important differences between passive FPR polarizing displays and active displays with alternative frame rates and frame sequences.
Passive 3D (Polarizing Film-Type Patterned Retarder)
This type of display uses the wave qualities of light to control the image that each eye sees. This display relies on a polarizing filter covering the screen. This filter has two orientations: one for even lines, the other for odd lines of resolution. Each line displays an image intended for one eye. The viewer must wear polarized glasses to experience the illusion of three-dimensionality. The glasses do not use electronic components, but simply apply a thin layer of material to each eye to serve as a polarizing filter. The filter in front of the right eye blocks lines intended for the left eye and vice versa. This way, each eye gets its intended perspective, even though the image is being displayed to both eyes at the same time.
This diagram describes the principle of FPR technology in the HP 2311 gt monitor. Passive polarizing displays are also installed in most movie theaters, but they use a different method that does not halve the resolution.
Benefits of Passive 3D
Now let's look at the features of FPR displays. First, the glasses don't use active electronics, so they're cheaper and less bulky than active shutter glasses. In fact, they're so cheap that they give you one for free to watch movies in the theater. As we already said, you can even use cinema glasses equipped with RealD technology.
Second, many people find polarized displays more comfortable for long periods of viewing because there is no 60-Hz flicker, which is less eye-straining. There are people for whom this greatly bothers, and there are also those for whom the active shutter does not tire at all.
Also, passive FPR displays allow the user to see the light from the display constantly. In glasses with an active shutter for each eye, it is closed half the time, which negatively affects the brightness.
FPR displays operate at 60Hz, so a standard HDMI cable is sufficient for stereoscopic operation. However, active systems require 120 Hz output to provide 60 frames per second per eye. As a result, with active shutter technology via an HDMI 1.4 cable, you will only get 60 frames per second at a maximum resolution of 720p. This doesn't mean you can use any old 3D TV with polarized glasses. However, like a polarizing monitor HP 2311 gt, passive 3D technology is definitely more accessible.
Disadvantages of Passive 3D
The benefits of polarization stereoscopy are impressive, aren't they? But there is one important nuance. Speaking of FPR displays, each eye only sees every other scan line, in other words, half the frame. This affects small details most of all; for example, small text in a computer game may be difficult to read. The closer you are to the screen, the more obvious this effect becomes. It significantly degrades image quality. Thus, the loss of resolution will be much more noticeable if you are in front of a PC monitor than sitting on the couch in front of a 3D TV.
In addition, a polarizing filter on the screen implies an optimal viewing angle. If you deviate too much from it, various anomalies will begin to appear, such as halos, which will spoil the perception of the image.
Active 3D (shutter, alternate frame sequence)
Alternate frame shutter systems use active shutter glasses. As you can guess from the name, the image output to each eye is blocked in turn. The display should run at 120Hz, meaning each eye sees 60 frames per second.
The infrared emitter is responsible for sending a signal to the glasses to block the corresponding frame, so each eye sees one frame, and the next one intended for the other eye is blocked. At 120Hz, it happens so quickly that you don't notice the flicker. Most of all, this process affects the brightness of the image, which drops noticeably.
Points in the active system play main role, and the shutter requires power to operate. This means that they are delicate batteries that need to be charged or replaced. The glasses also have wireless synchronizers and transparent LCD screens, which is why they are so expensive ($50-$200). Multiply this by a family of five and you have a deciding factor in purchasing such technology. In addition, the loss of half the brightness in each eye is very noticeable. Finally, the active circuit makes the glasses very bulky.
Active displays can deliver true 1080p resolution to each eye at 60Hz. Unfortunately, the HDMI 1.4 standard does not offer enough bandwidth to support so much data. Therefore, a typical 3D TV is limited to 24 FPS at 1080p. This is suitable for a Blu-ray movie, but is no longer acceptable for smooth gameplay. To do this, owners of GeForce video cards need to select a monitor that supports 3D Vision. And if you have a relatively new map Radeon, then it is better to find a monitor with AMD HD3D. AMD Radeon HD 7000 series graphics cards support the new "Fast HDMI" standard, which delivers 60 FPS at 1080p over HDMI. But due to the lack of an appropriate monitor, this technology will not appear in today’s review.
HP 2311 gt | Polarized Displays: Standards Compliant
One of the biggest potential benefits of polarizing monitors is our full support for Nvidia's 3D Vision standard (via 3DTV Play) and AMD's open HD3D standard. HDMI is suitable for gaming at 60 FPS at 1920x1080 resolution on a passive display because the visual information needed by both eyes is presented in the same frame. That is, for 60 FPS a monitor with a screen refresh rate of 120 Hz is not needed. However, the vertical resolution is reduced by two.
Testing has confirmed our theory, the AMD HD3D seamlessly delivers stereoscopic 3D at 60 FPS at 1920x1080 via HDMI on a monitor HP 2311 gt. On the other hand, Nvidia 3D Vision/3DTV Play technology did not work for us.
We mistakenly assumed that Nvidia 3DTV Play would correctly detect an HP monitor and work on it. However, the latest 301.42 driver didn't want to enable the feature when we connected an Nvidia 3D Vision transmitter. After doing a little research, we found out that Nvidia drivers are very picky about monitors that need to recognize 3DTV Play.
When we started writing this review, the Samsung S23A750D could be found for 13 thousand rubles, but the model may soon disappear from sale. However, it has an analogue - Samsung S23A700D, which differs only in the absence of DisplayPort.

HP 2311 gt | Comparison of stereoscopic 3D image quality
Let's compare monitor image quality HP 2311 gt with circular polarization and Samsung monitor with a frequency of 120 Hz. While we can't exactly describe the differences in the stereoscopic 3D images of these monitors, we can take photos through the glasses to demonstrate each system's strengths and weaknesses in brightness, ghosting, and clarity.
Brightness
According to the brightness of the image HP 2311 gt looks much better than on an active type monitor. This is due to the fact that polarized glasses allow light to pass through all the time, while active shutter glasses block it half the time for each eye.
Looking at the image in GIF format, you will understand everything right away. Photos of each display through the glasses were taken with the same camera with the same manual settings. Here at HP 2311 gt unconditional advantage.
Ghosting and viewing angles
The operation of 3D filters on a passive polarizing screen is only effective when viewing the image from an ideal position. If you move from it, then perhaps the images for different eyes will be mixed up and you will see the so-called halos. Additionally, polarizing filters are not 100% effective. So you can encounter halos even in the optimal position. An active shutter system does not have this problem, and you can view the screen from different angles without ghosting.
Looks like HP 2311 gt The ideal viewing distance is approximately 75 cm, where the 3D effect is best seen. Each user has their own comfortable distance to the monitor, but, on average, for a 23-inch screen it is approximately 45-50 cm, which means that you will have to sit further from the display than usual.
Offset to the right or left of the monitor HP 2311 gt it has virtually no effect on the quality of the picture, but moving up and down at a distance of 75 cm causes significant anomalies in the form of halos. The monitor has tilt adjustment, so setting the desired angle is not difficult. But, still, you are forced to look at the monitor from one position. And if several people are looking at the monitor, they should all be at the same level as you. This is illustrated in the image below:
Even in the best position HP 2311 gt suffers from slight ghosting, while the Samsung panel does not. By the way, if you look at the screen a little from a height, the picture becomes brighter, and on both displays.
Definition
Polarized displays are best for watching movies while sitting on the couch, for example. But, as usual, you sit much closer to the PC monitor. In this case, the lack of clarity can be a serious problem.
It is easy to notice that on HP 2311 gt only every second line is visible, especially if you look at small parts or small font text. The TriDef 3D driver has a software line scanning option to increase the clarity of hard-to-read text in games. But it’s still hard to come to terms with what you see on the HP 3211 gt screen.
Compare HP 2311 gt with Samsung 120Hz, which provides impeccable clarity in 3D mode.
We should note that the shots for the animated image were taken through one lens of each 3D glasses. It is logical to assume that when the image from the display is perceived by both eyes, you will be surprised by all 1080 lines of total resolution. However, in practice, the situation is even worse than in the GIF image. Clarity is the monitor's biggest problem HP 2311 gt in games in 3D mode.
Desktop image quality Windows desktop
Polarizing filters applied to the screen HP 2311 gt, have a barely noticeable effect on the displayed image even in 2D mode without glasses, especially if the screen is uniformly filled with one color. It is not significant, and for some people it is not noticeable at all. However, if for a long time look at the background white color of the leaf in Microsoft Word, your eyes will notice the difference between Samsung's 120Hz panel and HP's polarizing screen.
Photos don't show this visual effect very well, so we don't have an image to demonstrate it. But we can assure you that non-polarized monitors do not have this problem, since they do not have appropriate filters applied to them.
HP 2311 gt | Entry-level 3D display at a reasonable price
Recently at one of the exhibitions we saw several people playing Battlefield 3 on big screen TV with passive stereoscopic 3D. Participants stood behind a line approximately one meter from the display. The spectacle was magnificent, and later we asked one of the players whether each eye sees the full 1920x1080 resolution or only half. He replied that the picture looked like full HD. It turns out that in this game from such a distance it is almost impossible to see the difference.
However, you won't be using a 3D capable monitor from three meters away. The distance to it on the table will be much less. And in this case, the polarizing FPR monitor will have a hard time, since each eye will only see half the resolution. But HP 2311 gt must work in such difficult conditions. Luckily, 3D movies look pretty good from the right distance and orientation. Game images are also tolerable, although the lack of clarity can be quite annoying, especially when small environmental details and text play an important role.
HP's pricing policy reflects its position HP 2311 gt On the market. It costs approximately 11.5 thousand rubles, which is 1500 cheaper than a 120 Hz display of the same size, which is a fair price for an FPR-based 3D monitor. It has several advantages over active shutter systems, such as very affordable glasses, higher brightness, and no 24 FPS cap in HDMI gaming at 1920x1080. This is a great option for people who want to immerse themselves in stereoscopic 3D without spending a lot of money. It also performed well when working in 2D on Windows.
For more discerning gamers who crave stereo imaging on a PC, a 120Hz monitor and active shutter glasses will be a better option, budget permitting. Passive polarizing screens are more suitable for the living room, where there is more distance between you and the display. When watching movies, you are unlikely to notice fuzzy text. In addition, families with restless children will appreciate the low cost of glasses.

Stereoscopic images on computers have been promoted almost since the advent of the first video cards. However, 3D Stereo gained real popularity only in 2008, when NVIDIA presented 3D Vision. Over the past time, the developers have brought the technology to fruition and at the beginning of this year they announced 3D Vision 2, released new glasses and came up with some interesting features.
Theory of operation
First, let's tell you how the first version of 3D Vision worked. To create a stereoscopic image, NVIDIA chose one of the simplest and at the same time technologically advanced methods. The video card calculates its own images for each eye and displays them one by one on the display. In turn, special shutter glasses cover one or the other eye.
In the end, 3D Vision required three components: an LCD display with a frame rate of 120 frames per second, GeForce video card and glasses. For those who are particularly picky, NVIDIA offered 3D Vision Surround - the ability to play on three monitors simultaneously, but before the release of the GTX 680, this required an SLI connection of two or more video cards.
New glasses, monitors and Light Boost
The changes in the new 3D Vision are in the details. First of all, the glasses themselves were transformed. Ergonomics have been improved: the arms have been redesigned so that it is comfortable to sit in the headphones, and a rubberized rim has appeared around the perimeter of the lenses, making it easier to wear the eyepieces for a long time. The frame frame has become deeper and more effectively combats side light. The glass itself has increased by about 20%, which made it possible to expand the viewing angle. We also paid attention to optimizing the LCD shutter switching algorithms to get rid of phantom images and flickering.
Otherwise everything is the same. Powered by a battery, charging via mini-USB, operating time - 60 hours. To communicate with a computer, the same IR emitter is used, which can be built into the monitor or sold as a separate box. It is interesting that, despite all the improvements and increase in size, the weight of the glasses has remained almost unchanged: 56 versus 51 grams for the previous version.
Another innovation is monitors. 2 models compatible with 3D Vision are equipped with technology 3D LightBoost. When you turn on the stereoscopic mode, it automatically increases the brightness level of the screen, which eliminates the annoying dark picture and ghost images, and also allows you to keep your glasses always open. This means that with 3D Vision 2 you will finally be able to clearly see everything that is happening around you. With the first version of the technology, even typing had to be done by touch.
The first 67 centimeters
To test the new product, we ordered one of the first monitors with support for 3D Vision 2, ASUS VG278H. It is based on a matte LCD panel with an impressive 27-inch diagonal and Full HD resolution. The scanning frequency is 120 Hz, the response time is 2 ms. Declared brightness in standard mode limited to 300 cd/m2. The monitor has a built-in IR emitter - it is hidden in a small protrusion above the screen. The VG278H can receive images via DVI, HDMI or D-sub. In addition, there are two audio jacks: an input for the built-in stereo speakers and a headphone output. The VG278H comes with 3D Vision 2 glasses - no need to buy anything additional. At the time of writing, the monitor was valued at 26,000 rubles. For comparison, we took ASUS VG236- 23-inch display with support for the first version of 3D Vision.
Tests
For testing new technology We chose two games: Battlefield 3 And Trine 2. We first tried the game on the VG236 and only then switched to the VG278H. The difference is huge. It feels like you were watching an old CRT TV, and suddenly they put a Full HD panel in front of you - colors appeared, normal brightness, artifacts disappeared. The picture looks so great that you almost don’t notice that you’re wearing glasses.
The films give me even more impressions. We saw on the computer the effects planned by the directors - airplanes flying out of the screen, soap bubbles floating at nose level. The first 3D Vision simply didn't have all this.
Eventually
While 3DVision 2 still requires a 120Hz monitor, glasses and a GeForce graphics card, the new technology option is definitely big step in the development of stereoscopic imaging on a computer. Finally, we got what cinemas and TVs with 3D Stereo support have been offering for a long time - a bright picture and normal effects. Of course, it is difficult to say how much new technologies and glasses contributed to this; Perhaps the volume effect appeared due to the significantly increased diagonals of monitors. But in any case, when choosing between the first and second versions of 3D Vision, it is better to give preference to the latter.
PROS:
- bright picture
- large lenses
- increased display diagonal
- compatibility with previous generation glasses
MINUSES:
- monitors are too expensive
We also note that before purchasing such a monitor, you need to take into account a number of nuances. Firstly, to work with 3D you will need a fairly powerful video card, especially when it comes to modern games. So before purchasing, it doesn’t hurt to clarify whether the system will handle the planned 3D content. Secondly, the 3D glasses mentioned may not be included in the package (there are screens that do not require glasses, but they are extremely rare). Thirdly, the 3D picture must be seen with both eyes at once; In case of binocular vision disorders (strabismus, absence of one eye, etc.), normal viewing of such content will be impossible.
It has been more than two and a half years since 3D Vision technology was first introduced to the masses and inexpensive solution to get a three-dimensional picture on a PC screen, and on the pages of 3DNews a review was published “NVIDIA GeForce 3D Vision Stereo Glasses - Long Live Volume!” . By the way, if we talk about generations of NVIDIA stereo 3D technology, the version of 3D Vision presented today with index 2 should, by and large, be called the third. If you remember, for the very first 3D Vision glasses, monitor manufacturers were able to introduce 120-Hz models that had a maximum screen resolution of only 1680x1050 pixels, mostly with a diagonal of no more than 22 inches.
Only much later did LCD displays appear, the matrices of which had a full Full HD resolution of 1920x1080 (1920x1200) and a diagonal of 23 or 24 inches. It was at this second stage of development of 3D Vision technology that the second, more ergonomic and economical generation of 3D glasses was introduced.
The prevalence of stereoscopic content has also grown by orders of magnitude in recent years, and the variety of games, videos, applications and, most importantly, their quality are now able to satisfy even the most sophisticated demand. Suffice it to say that if at the beginning of this path many popular games were actually converted from a two-dimensional format to a pseudo-3D one, then recently most development teams are trying in one way or another to initially develop 3D game engines taking into account the requirements of stereoscopic perception by the viewer. By the way, it was NVIDIA that did a simply gigantic job of adapting hundreds of modern games to optimal performance together with 3D Vision technology, and today there are more than 550 such games.
And would you know what gorgeous stereo 3D toys await us in the coming months!
This is not to say that NVIDIA's competitors have been doing nothing all this time. You, of course, have heard about the stereoscopic technologies of Intel InTru 3D and AMD HD3D, but look at the slide below: to its credit, no other company in the computer market has done as much to popularize stereo 3D games as NVIDIA has done. number of different computer systems with support for 3D Vision (laptops, desktops, nettops and the like) has long been in the hundreds.
As a matter of fact, all this protracted introduction is necessary in order to emphasize one very important fact. The reality is that for some of us, a stereoscopic computer and the corresponding stereo content in the form of games, videos, movies, photographs and the like have become commonplace a long time ago. We play, shoot and edit videos, enjoy movies, but... we are all human, and sooner or later we want a serious upgrade. And if more powerful video cards supporting more and more new technologies and effects are released with enviable regularity, the celebration on the street for stereo 3D lovers happens less often.
But it happens.
So, meet: 3D Vision 2. Key differences from the previous generation technologies are as follows:
- Absolutely new design active shutter 3D glasses with improved characteristics;
- New generation of 27-inch monitors with built-in emitter;
- NVIDIA 3D LightBoost technology.
First of all, about the new glasses: the size of the eyepieces in the 3D Vision 2 version has increased significantly, by about 20%. The developers made this move taking into account several considerations at once.
First of all, by increasing the size of the “glasses” the player’s field of view increases, which makes sense in relation to the new 27-inch monitor diagonals. For those who run computer games on 3D TV screens with a diagonal of 40 inches or more, an increase in viewing angle will also be a pleasant innovation.
In addition, increasing the size of 3D glasses will make it much more convenient to use them together with regular diopter glasses.
The new glasses are made of modern composite materials, so the increase in size has not affected their weight at all; the glasses are still light enough and comfortable for long-term use. However, now the controls have changed somewhat: the button to turn on the glasses in new version transferred from the upper edge of the left arch to its lateral plane. The button itself has also become significantly larger.
What should be especially emphasized: for glasses and devices supporting 3D Vision of the first and second generations, full reverse interchangeability is guaranteed.
But that is not all. A really serious change in the technical design of the glasses was the additional optimization of the algorithm for switching between the LCD curtains of the right and left eyes. The optimization is carried out in such a way that the open time of each curtain is reduced to a minimum and synchronized as accurately as possible with the signal coming from the emitter, as a result of which it was possible to further reduce the side effect of “flicker”.
Thanks to the help of the employees of the Russian division of NVIDIA, for which I thank them very much, I was one of the first to try out the new 3D Vision 2 3D glasses in action. I confirm on personal experience: putting on the new 3D glasses over regular diopter glasses is now much more convenient than in the case of more compact, but at the same time less “deep” glasses of the previous generation.
No matter how hard I tried, replacing the previous generation of glasses with a new one and back, to catch the difference in the light transmission of LCD screens, I was unable to detect any. The fact is that the picture on the monitor screen seemed unusually bright to me, and the first thing I thought, of course, was that it was the new glasses.
A few words about monitors supporting NVIDIA 3D Vision 2 technology. At the time of the announcement, two such options were presented. The first is a 27-inch ASUS VG278H LED-backlit monitor with a resolution of 1920x1080 and support for 2D and 3D modes. The second option is laptops of the family Toshiba Qosmio X770/X775 and Satellite P770/775, equipped with a 17.3-inch 1920x1080 screen, also supporting 2D and 3D modes. Of course, in both cases the new 3D Vision 2 3D glasses are included.
Both options feature a built-in 3D Vision emitter. Yes, that’s right, that same “pyramid” with a USB interface, which was previously supplied separately in the kit, will now be built into not only laptops, but also some models of 3D monitors.
Modern monitors such as the ASUS VG278H can handle both processing a stereoscopic Full HD video stream from a PC (Dual Link DVI interface) and working together, for example, with a Sony Playstation 3 game console (HDMI 1.4a interface).
It's interesting to note that the built-in 3D Vision 2 emitter is located on the top of this monitor.
Now all we can do is talk about the timing of the appearance of new products in retail and approximate prices. In the US, deliveries of new 3D Vision 2 kits and separate glasses will start at the end of October. In Russian retail, as they explained to me at the Moscow representative office of NVIDIA, these new products will appear in the new year, 2012.
Nevertheless, those who urgently want to join the new generation of technology can not lose hope, because it will be possible to purchase new 27-inch 3D monitors (and perhaps laptops) even earlier. Thus, the aforementioned 27-inch LED 3D monitor ASUS VG278H, complete with 3D Vision 2 glasses, will appear in global retail in November, so its appearance in Russian stores may well take place before the Christmas holidays. By the way, it is quite possible that several more manufacturers will announce the release of new models supporting 3D LightBoost technology in November. In particular, we can expect announcements of such models as the Acer HN274HB and BenQ XL2420T/XL2420TX.
Now about the prices. For North America, the price of the NVIDIA 3D Vision 2 kit (glasses plus USB emitter) and separate 3D glasses will be exactly the same as it was until now for the current generation of devices, that is, $149 and $99, respectively. Of course, it’s too early to talk about prices in Russian retail, but NVIDIA confirmed to me that our pricing will remain approximately the same, that is, the new set and new glasses will be offered at the same price at which current 3D Vision models are currently sold.
Finally, the ASUS VG278H 27-inch monitor bundled with 3D Vision 2 glasses has an MSRP of $715.

When choosing a monitor, pay attention to the following factors:
- diagonal. The bigger the better, because a large monitor gives the player the opportunity to be more immersed in the game, and the cinema lover can create the feeling of a home cinema;
