The idea
Instead of using 120 Hz for a single image, the graphics card sends two images at 60 Hz. The glasses, which are made up of two LCD screens mask first one eye, then the other. It’s then over to your brain to handle the image like it would any “real “ object and mix the images to get the 3D effect.

The Samsung SyncMaster 2233rz is a bit of a mouthful to say but shouldn’t have much trouble in making itself known as it joins a select group, the B2403ws, PhrophetView 920, AS4314UTG, 10 20 35, 2407WFP… Take note: here we have a new legendary screen, a monitor that turns the world on its head, introducing a real technological change and even, let’s not be afraid to say it, a true revolution in terms of LCDs.

The 2233rz is the first 120 Hz LCD on the market. A real 120 Hz, not interpolated. If the graphics card can handle it, it will display 120 images per second in games, with at the same time, what is basically zero image ghosting – responsiveness just isn’t an issue – and improved fluidity.

Revolution n°2: if you have a recent 3D NVIDIA card, you will be able to get yourself the wireless 3D glasses so you can play… in 3D. In fact NVIDIA is recycling an old technology here, making the most of the technical advances of the last 10 years. In the meantime, game quality has improved considerably, 3D cards are much more powerful, LCDs have moved ahead of CRTs… The glasses were in fact available too early. Now they’re perfect and quite simply give an amazing effect! The whole editorial team gave them a try as did quite a few other people who just happened to be around! Verdict: everyone was knocked out and had a great time blasting zombies that are even more scary as they come at you in 3D, or skidding around a racing circuit.

Gettting back to the tests: we start with responsiveness. This is the first ''5 stars''!

So then, the first 120 Hz, and the most responsive LCD we’ve tested in the last 8 years. To recap, we haven’t been measuring reactivity in terms of miliseconds for a few years as we don’t see this as an accurate way of judging, but rather in terms of the average number of residual frames. That’s to say in terms of coloured and light images that ghost behind a moving object. It is these imgaes that create a blurred impression (coloured residual images), and white ghosting (transparent residual images). The first score proves much higher than the second, which causes only very slight problems. Here are the comparison scores:
The Samsung SyncMaster 2243rz sweeps the board:


The 120 Hz mean that it has half the ghosting of the fastest LCD that we’ve previously tested. Impressive!
The second plus point in terms of gameplay is the display delay remains under one frame; a delight for gamers.

120 Hz or a move to 3D?

For those who are willing to pay, the screen gives access to a whole new way of experiencing games: 3D. Apart from the 120 Hz screen (real 120 Hz, not interpolated as on televisions), you also need to have an NVIDIA graphics card higher than a 9600GT (at the moment ATI does not have a 3D solution) and the pair of glasses that go with this technologie. At the time of publication of this test, prices are not yet definitively fixed. They should be by March 2009 (the date when these products have been announced for).


3D in practice

315 games are already compatible with this technology to a certain degree. We have focussed on 6 of them:

Race Driver GRID
The 3D effect is already good in this game without the glasses. Using them increases the 3D sensation but without revolutionising the gameplay. Alternating with and without glasses gives a nice variation in effect. If you look at the image of the inside of the cockpit you can see some of the limits in terms of development. Not all the instruments are in 3D.. The steering wheel, for example, or some of the measures on the dashboard are not in 3D on all the cars.


Left 4 Dead:
3D functions perfectly in this game. Excellent. Everyone had a great deal of pleasure with this. Even non-gamers. The depth effects are impressive when you go down the escalators or jump in holes from which gangs of zombies appear.

We did note some bugs (even if they didn’t stop us from playing): flashes of white light in some lighting (particularly visible in the metro), and white shadows on objects of your team mates which have more and more of an effect the deeper you go into 3D effects.

Far Cry 2:
Very good again, we prefer the 3D to the classic version of the game. Once you’ve had a taste of the 3D with glasses, it’s difficult to go back to the classic game.

There are nevertheless a few little things that need correcting. The main 3D problem in Far Cry 2 is how the sight is placed. The sighting crossmark itself is not in 3D but stays on the surface of the image. This is a bit disturbing in the game as you’re constantly refocussing on it. Either you see the cursor in the foreground, or in the back of the screen. This jungling makes your eyes tired, not because of the glasses themselves but because 3D hasn’t been fully implemented into the game. Everything else was very good and we are waiting impatiently for this problem to be resolved so we can fully enjoy the game.

World Of Warcraft:


There are still a few WoW fanatics in the editorial team: long live 3D! However, here aswell the selection function doesn’t appear in 3D. It remains on the surface. We hope there will be a patch to correct this point, which is a problem when you look to click on an enemy in the back of the image field. Note that Blizzard has produced a special patch that should allow an advanced image 3D, contrary to other games which are all in depth at the moment.

Call of Duty 5:

Call of Duty has a 3D sight like Left 4 Dead. Over all the experience is agreable with just one bug that we noticed: the sight jumps and is doubled when the arm is placed in sight mode and you take aim at an enemy.

Civilization 4 :


3D functions but to the great disappointment of Vincent Alzieu, there is no real point to it. Apart from playing with the zoom function, the glasses give nothing extra. This type of game doesn’t yet lend itself to 3D. The developpers would need to move to a much better updated Civ 5 instead of pursuing an aging concept that is hardly updated. Such an opportunity could justify the appearance of new, different, richer games, which wouldn’t be a bad thing in an era of the rehashing again and again of concepts that work…

Overall rating

With the exception of WoW, 3D is only generated in the deep part of the image. Objects that come out of the screen and move towards you are not handled. Players arms also do not have any physical existence. For example your gun goes through fences and is not affected if you move it to the side through the bars. In the future, provision will have to be made for this so that guns cannot go through walls and other objects.

Keep in mind that these games were developped before the 3D NVIDIA solution became available. We hope that games under development at the moment and in the future will be able to take this new dimension into account and correct the faults noted here. 3D is without question the future of video games (probably without glasses one day, but that will be for much later…) What’s more, this technology, in contrast to the solutions by Hyundai or Zalman, causes little tiredness on the eye (or not at all in some cases).

The good news for people who wear glasses is that they do not prevent you from enjoying 3D.

Ergonomics and colours

In terms of ergonomics, this screen has a similar design to the 2233BW, but without the VGA socket. There is a DVI socket at the back, a base on a platter and flowers stencilled into the back.



The colours are not well set. Both blue and orange come out a bit too much, which is why you get the dominant violet within the greys. Unfortunately we weren’t realy able to sort this out with the manual settings. At best you get a deltaE or 6.9 which isn’t great obviously. You’re left with the option of the calibration profile that is available here

The contrast is higher than 950 : 1, which allied to its excellent responsiveness, limits flickering in videos. You therefore get a better image than average for films.
Pluses
-
Excellent responsiveness, the best on the market
-
New game experience with 3D glasses from NVIDIA
-
High contrast
-
Better than average on films
Minuses
-
Colour rendering modes are poor
-
Weak ergonomics
-
TN panel = closed angles of vision
-
Price not yet fixed but likely to be high: 300, 400, 500 euros?
4
The 2233rz is currently the most responsive screen on the market adn by far gives the best performance in 3D. This makes it the reference point in terms of screens in these two domains and gets it a 5-star rating from us. Nevertheless the ergonomics and colour quality leave something to be desired and will no doubt relativise the rating when other similar products come onto the market.

3D Vision 2 Glasses

The New 3D Vision 2 Glasses



Upon first glance, the new 3D Vision glasses may look the same as the outgoing model but there are a number of changes built into their design. Nonetheless, NVIDIA has retained their iconic profile and black and green colour scheme while the underlying technology itself hasn’t changed one iota; these are still active shutter glasses which receive their signal from an infrared emitter. Their range has remained the same at around 40 feet provided a clear line of sight between the emitter and glasses is retained.

Instead of plastic these are fabricated out of a durable composite nylon which makes them very, very durable while minimizing on weight. The matte finish also prevents any unwanted scratches and ensures that finger prints become almost invisible. Unfortunately, the material NVIDIA used causes a few small squeaks when the glasses are manipulated but I’m going to guess our pair just needed to be broken in a bit more.

Note that in the picture above and those below, it appears the lenses are different colours but that is just an effect of the polarization at certain angles.


Starting off at the front of the glasses, NVIDIA has included a small return at the top and bottom which acts as a baffle to prevent light from entering around the frames. The previous design used a completely flat frame and in daylight viewing conditions, light tended to seep in and diminish the contrast and brightness of on-screen images. Hopefully, this small but significant addition will all but eliminate that issue.

Above you can also see a glossy finish around the outer lens which looks good but as we will discuss in the Initial Impressions section, it does cause some significant issues as well.

Instead of a mini USB connector of yesteryear, the 3D Vision 2 glasses use a micro USB connector that can accept power from most cell phone chargers. This should allow for a complete recharge from any power outlet provided you have a micro USB charger. Battery life has remained constant at 60 hours of continual use and roughly three months of standby time.


Along with a brushed black chrome cover, the area directly over your temple includes a small on/off button with an integrated LED. Personally, I found the button nearly impossible to hit once the glasses were on my head and it will take several minutes of fumbling around before you find it in a dark room.



The changes continue onto the sides which have been slimmed down and shaped in a way that will have minimal impact upon headphones. Also, instead of the frames resting only on your ears this new design lightly clasps the back of your head for additional security. Coupled with the glasses’ feather-like weight, this addition allows 3D Vision 2 to steamroll the older generation unit when it comes to long term comfort.


Much like the older glasses, interchangeable nose bridge “adaptors” are included to ensure perfect fitment.



When placed next to the outgoing glasses, 3D Vision 2’s differences really become apparent. The new version looks much larger due to the installation of light baffles but also because NVIDIA increased the lens size by a good 20% for wider viewing angles. In addition, the infrared receiver has been moved from the right hand side to a central location between the lenses.

Along with the increase in lens size, the polarization has been slightly changed as well. These new glasses are supposed to let a bit more light through the active shutters which should increase in-game contrast and brightness.

NVIDIA claims they listened closely to gamers’ feedback when it came time to redesign their 3D glasses. From what we have seen, it looks like most of the changes will indeed benefit the in-game stereoscopic experience but most of 3D Vision 2’s differences come from the supporting monitors. That’s exactly what we’re going to look at next.
 

NVIDIA 3D Vision 2

NVIDIA 3D Vision




Like many of you out there, stereoscopic 3D and I have had a love / hate relationship since it became the latest cultural meme. Even though Hollywood, HDTV manufacturers and everyone in between is contently occupying themselves by jamming all things 3D down our collective throats, positive experiences have been few and far between. Most blockbuster movies have done nothing but drive viewers away with shoddy stereoscopic editing (there are few noteworthy exceptions though) while HDTVs are a long ways off from eliminating their own set of highly publicized issues with this technology. So all intents and purposes, the current state of stereoscopic 3D is languishing simply because good examples of it are few and far between.

NVIDIA has arguably been a pioneer in this area since their original 3DVision was actually one of the first stereoscopic kits available to the mass market. Due to the issues mentioned above they’ve been waging an uphill battle against the stigmas associated with 3D. However, through a tightly controlled set of certification guidelines, this solution has remained a high quality, viable option for PC gamers who are looking for a more immersive experience.


Even though it was originally released more than two years ago, 3D Vision has been evolving on a number of fronts. The supported game list was at first an impressive 125 titles but that number is expanding at a rapid pace and now holds about 550 games. NVIDIA’s progression has been constant on the support structure as well by introducing Youtube3D compatibility and the 3Dvisionlive.com site where a wide variety of user generated stereoscopic content can be viewed and uploaded. 3DTV Play may have passed under many people’s radar but it has proven to be a significant milestone since it allows a PC’s 3D content to be displayed on most HDTVs.

As 3D Vision has matured, the technology within the supporting monitors and active shutter glasses has stayed at a relative constant but the display industry itself has been moving forward by leaps and bounds. Now NVIDIA is ready for the next logical step and by working closely with their partners, 3D Vision 2 has finally become a reality.

This new version of 3D Vision shouldn’t be considered a revolutionary leap into some magical world of stereoscopic viewing. Rather, NVIDIA improved things on two basic yet very important fronts: the way certified monitors push 3D content and the design of their glasses. New panels will sport “LightBoost” which is a feature that implements for a more lifelike picture while the new glasses sport larger lenses and a rugged material selection. When both are combined, the experience should be more refined than it was in the past while offering tangible benefits over the older system in terms of usability, comfort and lasting appeal. We’ll get into the specifics later in this review.


For the time being both the original kit and 3D Vision 2 glasses will be sold in parallel with the new design eventually taking over. So if after reading this review you want to stick with the new glasses, the time to buy is now.

NVIDIA has certainly started their 3D Vision 2 campaign off on the right foot by ensuring this new improved kit doesn’t cost a penny more than the current one. While a pair of glasses will be included with every LightBoost-certified monitor, the wireless kit (with the active shutter glasses and emitter) will retail for $149 and the wireless glasses will cost $99 if bought separately without an emitter. In our opinion, this continues 3D Vision’s tradition of being one of the more affordable stereo 3D technologies on the market.


In terms of compatibility things are looking great for those of you who already have a 3D Vision kit. The original glasses are forwards compatible with and will be able to take full advantage of new monitors that sport 3D LightBoost. Meanwhile, 3D Vision 2 can be used on older 3D Vision Ready products like the Samsung 2233RZ and Acer GD235HZ.

When taken at face value, it really does look like NVIDIA has hit all the right buttons with 3D Vision 2 but as we all know, sometimes change isn’t a good thing.
