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.

    Why is there no support for 3DTV Play? They have HDMI 1.4 and support various formats(SBS, Over under, interlaced). Did Nvidia announce they will not support it due to marketing reasons or is there a technical difficulty?

    I sell my Zalman because half resolution disturb me a lot.
    I still wait for full res/eye.

    i had purchased lcd tv last year that was not good in features but now i am quite impressed with FPR 3d tv so i am planning to buy 3d which is released with latest technology like brighter & clearer image.

    i am seeing FPR 3d tv since a month back it is truly unique technology of lcd tvs and its monitors are quite impressive. if we go through feature wise than FPR 3d tv gives vivid image to the viewers and mind blowing cinema 3d.

    hey guys…
    i read out your comments over LG`s FPR 3d tv very interested but there is one more thing to say Full 3d monitors. these monitors have TN panel with led backlight more affordable prices, good response time and contrast.
