Mitsubishi just announced a 23″ Full HD 3D monitor with IPS panel and LED backlight that uses passive polarization and passive 3D glasses, just like with the new LG Cinema 3D monitors, expected to be available in Japan starting May 30th. The monitor is with a native resolution of 1920×1080 pixels, 3.8ms response time (Gray-to-Gray) and maximum brightness level of 250cd/m2 in 2D mode and 100cd/m2 in 3D, the contrast ratio is 1000:1 standard and up to 5000:1 dynamic. The Mitsubishi RDT233WX-3D monitor comes with two HDMI 1.4 ports, one DVI-D and DSUB 15 VGA connector, there is also a one D5 connector (component input used in Japan for different AV devices). The presence of the D-Terminal or D-tanshi analog video connector on this display probably means that it will be available only in Japan, so don’t get your hopes too high in getting the product in Europe or North America yet.
Thanks to the IPS panel used in this 3D display the viewing angles in 2D mode should be up to 178°, however when you put on the passive polarized glassed the vertical angle gets significantly reduced up to about 12° for best results in 3D mode. Due to the use of passive polarization approach in 3D mode you will be getting just half of the horizontal lines (vertical resolution) per eye, meaning 1920×540 pixels per eye, this is something that you should be well aware of as it is not the same as perceiving two full 1920×1080 frames. Also with this display, the maximum refresh rate you can use is 60Hz and not the 120Hz refresh that you can get in 2D mode with 3D LCD monitors using active shutter glasses.
Thanks to the HDMI 1.4 interface you should be able to use the monitor with consumer electronic devices supporting 3D like the PlayStation 3 console, however I’m not too sure how good games will look like on it as the PS3 outputs 720p 3D resolution and that may mean 1280×360 resolution per eye scaled… I still haven’t seen PS3 on a Full HD display with passive polarization in 3D. Mitsubishi does not mention anything about bundling of middleware for playing PC games in stereo 3D mode, apparently they target this display mostly for multimedia use. However thanks to the use of passive polarization technology you should not have trouble using the display with the iZ3D Driver or with DDD’s TriDef Software as they both support this kind of output for gaming in stereo 3D mode on the PC.

Do you remember the De-3D Cinema Glasses prank that ThinkGeek has pulled for April 1st this year, well the movie theater glasses that will turn a 3D movie into a 2D one are now real and you can buy them for $7.99 USD a pair. But why would you need glasses that make a 3D movie into a 2D one, when you can just go to a projection of that movie in 2D and not pay for a more expensive ticket for 3D projection? The answer is pretty simple, if you are not going alone to the cinema and only you have trouble when watching 3D and your friends still want to watch the movie in 3D, you can be with them and still watch in 2D with the special pair of glasses. The 2D Glasses are intended to be used in movie theaters using RealD projection technology and should be also compatible with most passive 3D television sets. They are not compatible with IMAX 3D movie theaters or ones using Dolby Digital 3D technology as these use different type of glasses, and of course they are not compatible with active shutter glasses solutions. Active shutter glasses such as Nvidia’s 3D Vision can also be modified to show 2D image from a screen displaying a 3D one, I’ve made a guide on how to do that.
Here is the real story behind the 2D Glasses from Hank Green:
In late 2010 I wanted to go see Tron Legacy. My wife was happy to come with me… as long as we went to the cheap theater where it was playing in 2D.
Really? Tron in 2D? What’s the point right? And then my wife told me something I never knew, she gets bad headaches when watching 3D movies.
She never complained about it, but there it was. I didn’t want my wife to be in pain, but I also didn’t want to go see Tron by myself. So instead of complaining (okay, in ADDITION to complaining), I got out my tools.
Instead of “recycling” the 3D glasses that my wife and I used during the movie, I took them home. After a lot of poking and twisting and gluing and cutting and cursing and sawing, I had created my first pair of 2D Glasses.
They’re not pretty, but I took them to see Voyage of the Dawn Treader in 3D and they worked! Katherine could watch the movie in 2D, and even switch to 3D for the action scenes!
She told some friends and by the next week, I had around 10 “orders” for these ugly 2D glasses. Stealing my raw materials from the theater became impractical, so I decided to get some nice ones made and make them available to the world.
What these 2D glasses actually do is to use two lenses with the same light polarization, instead of lenses with different polarization for the left and right eye as the typical passive polarized 3D glasses do. So basically in order to make a pair of 3D glasses into a one showing you 2D image from a 3D projection you just need to replace the right lens on the glasses with another left one. So instead of getting two slightly different images through each of your eyes and the brain fusing them into a 3D image with these glasses both your eyes will see only the left projected frame and it will still feel as a 2D image. And there goes the trouble and problem you may be experiencing watching 3D content, even though the projection would still be in 3D, you will be seeing a 2D movie with these modified glasses.

It seems that LG is not only interested in 3D HDTV market as well as 3D Gaming monitors, but also in providing a mobile 3D-capable solutions and as a result the company announced their first such product – the LG R590 3D notebook. The 3D laptop has a 15.6-inch screen with resolution of 1366×768 pixels and uses a passive polarization filter along with passive polarized glasses to provide the 3D effect. The software LG is relying to provide the 3D capabilities is DDD’s TriDef giving the user a 3D photo and video player, 2D to 3D video conversion and the option of gaming in stereo 3D mode. As with other such passive polarized solutions you should be aware of the fact that the vertical resolution is being halved when in 3D mode meaning that you get just 384 pixels per eye which can be an issue sometimes as it makes harder to read small text etc., so it is not the perfect solution as it also goes with more limited viewing angles and other typical issues for products using the passive polarization technology from other manufactures like Acer for example.
The laptop can be equipped with a fast mobile quad core Intel Core i7 processor, using HM55 chipset and Nvidia GeForce GT335M video card (72 stream processors) along with 1GB of GDDR3 video memory (128-bit memory bus) which makes the system quite capable in providing quite comfortable experience when you play most not so demanding games in stereo 3D mode with the available lower resolution display. But I will not be surprised if in a few moths time LG decides to switch to a 120Hz LCD panel and 3D Vision shutter glasses and/or maybe if there are alternative solutions using active shutter glasses by that time. The LG R590 3D notebook is expected to be available on the market around the middle of August, but there is no information yet about what will be its price.
