Mitsubishi Diamondcrysta RDT233WX Passive 3D Monitor With IPS Panel

April 27th, 2011 · 7 Comments · General 3D News


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.

LG’s new Cinema 3D Passive 3D Monitors, the D41P and D42P Series

April 26th, 2011 · 8 Comments · General 3D News


LG Electronics just announced the release of two Cinema 3D monitors series – D41P and D42P – using LG’s new Film Patterned Retarder (FPR) 3D technology (passive polarization filters) that was just recently announced in the new line of LG Cinema 3D HDTVs. LG claims that with their FPR 3D technology, the 3D monitors offer brighter and clearer images, and a “Flicker-Free” certified 3D picture that according the company makes 3D viewing more comfortable and eliminates the “occasionally caused dizziness and nausea among viewers” when watching 3D monitors using shutter glasses. You should however consider the fact that the flicker with shutter glasses is not the only thing that may lead to side effects and unpleasant feeling in the viewer, badly made stereo 3D content is actually the most usual cause.

Out of the first four monitors from the new D41P and D42P series – D2341P, D2242P, D2342P, D2542P, only the first one comes with just D-SUB and DVI-D connectivity (D2341P) and the other 3 models also feature support for HDMI 1.4. The LG D2341P is a 23-inch Full HD 3D monitor, the LG D2242P is 21.5-inch Full HD 3D monitor, the LG D2342P is 23-inch Full HD 3D monitor and the LG D2542P is 25-inch Full HD 3D monitor. All of them use TN panels with LED backlight, meaning more affordable price, have 5ms response time, 1000:1 contrast ratio (5 million to 1 dynamic) and provide up to 250 cd/m2 maximum brightness in 2D mode and 100 cd/m2 in 3D mode. The LG Cinema 3D monitors will be launched in Korea today and will be rolled out globally early June starting in Europe.



All four new models from the D41P and D42P series will be bundled with DDD’s TriDef 3D software that will be ensuring the stereoscopic 3D support for games, as well as 3D video playback and the 2D to 3D video conversion functionality. The TriDef software is universal, meaning it will work with both AMD/ATI and Nvidia-based GPUs and the models with HDMI 1.4 interface should be compatible with consumer 3D electronics such as PS3 consoles or Blu-ray 3D players. Have in mind that these monitors are not compatible with either 3D Vision or the 3DTV Play software from Nvidia and will not be made compatible in the future as well.

The main advantage of the use of passive polarizing filters is that it brings down the cost of the display and makes the glasses much more affordable as they do not need any electronics, just two plastic filters with different light polarization. The drawbacks are mostly the limited vertical resolution (the halved number of horizontal lines per eye), as each eye perceives only 1920×540 pixels, something that could bring some issues with distinguishing finer details and small text in 3D, as well as the significantly limited vertical viewing angle of the display when in 3D mode as compared to the angle in 2D.

A Bit More on the Topic About Active DisplayPort to DVI Adapters

March 21st, 2011 · 4 Comments · General 3D News


Here is an interesting find that I’ve stumbled upon today, an Active DisplayPort to DVI adapter from Sapphire. The interesting thing here is that the adapter is Active, but does not have an additional USB power cable, but if you are paying enough attention you should note that this adapter is providing just a Single Link DVI output. The adapter is originally intended to be used with AMD/ATI video cards fro providing video connection to more common monitors that are not using DisplayPort if you want to built a multi-monitor configuration based on AMD’s EyeFinity technology. This adapter however is not something that will work with a 3D Full HD monitor if your desktop or laptop has only DisplayPort output with the reason being that the output is not the Dual-Link DVI that is required to be able to push 1920×1080 video at 120Hz to the monitor. So you should be paying attention when choosing a DisplayPort to DVI adapter for use with a 3D monitor, you should look for an Active DisplayPort or mini DisplayPort to Dual-Link DVI adapter in order to make things work with high-resolution stereo 3D…
