Sweet!!!!!!!!! Maybe we'll get 8 track tapes, too.

cheers everyone

Seems like a decent monitor, should be similar to the Zalman. It does have a number of downsides you should be aware of, like reduced resolution and small viewing angles. But the 3D itself will probably look nice (when you are in the sweetspot). So its not going to be the best quality 3D out there, but should look pretty good on its own right.

Let us now how this works out for you [LG D2342P-PN (Passive)]. I would be interested in your findings. Thank you.
cheers

-check this out guys , this is my new favorite youtube video, I call it:
the FUTURE meets CRT ( CRT jr. )

I own an MEMS laser projector, and while it is very nice, they will NEVER, EVER go mainstream. There are very strict limits on how powerful collimated lasers can be in consumer devices when they are not fully contained, as in a laser projector. You will never see laser projectors on the market that are over 50 lumens or so because of that.

(...)
wrong!

then hackers do it and who gives a flying f about mainstream. :b

Just gimmie a decent pointing mirror.

BTW laser pico paralleled sounds like a dream,but they should give us about 150 lm at least.

The mirror is not the problem, it is the triple laser alignment.

You might not guess it, but I am actually an avid laser enthusiast and experimenter, and I have quite a few I have made!

Red, green, and blue lasers all have very different beam shapes/characteristics. Getting them to all be the same shape and width requires custom optics that need to be very close to the diodes, and perfectly aligned. The only way to do that would be with custom optics and housings that would cost tens of thousands in a small batch, for the tolerances needed.

And then, after you have all the beams shaped properly, you need to have them going in the exact same direction, with NO divergence. I use these for my RGB laser: http://www.o-like.com/index.php?main_pa ... ucts_id=66

They let you combine the three beams, but getting them to not diverge at any kind of distance is very hard! I can adjust my laser to still converge on the same point at 20 feet or so, but just the heat from the lasers running for a few minutes expands their metal mounts enough to shift the beam every so slightly. The beam in the air is still white, but at the other end, it is just a red, green, and blue dot all very close together. In a laser projector, this would be a deal killer. Apart from all the optical problems, you need an extremely accurate video timer to turn the lasers on and off at the right time. I really wish that it were possible to do (I would love to rip open my current 15 lumen projector and throw in my high powered custom RGB laser to get 600 lumens or so), but it is not possible on a hobbyist level, not for me, not for even the most experienced laser hobbyists in the field.

Microvision said they are scaling up their technology and this will be good . Once 1080p 120hz I'm sure in regardless luma. Others come too .

BTW where you got that laser from , you can take apart a LaserVue?
http://cgi.ebay.com/Mitsubishi-LaserVue ... 4cf6aaddb5

look maybe you should buy it!

Yes, Microvision is scaling up in resolution, but not brightness. They want to make their light engine smaller, not larger. Useful for handheld devices, but I could not handle 50 lumens for a home theater projector.

Thanks for that link, I will be looking into it. I have both of the Microvision projectors, and the RGB laser I have is custom built from scratch, using a 1200mw 445nm blue laser, a 300mw 532nm green laser, and a 1000mw 650nm red laser, along with all the combining optics and power supply boards.

...we are looking into this stuff too.
FPGA chip can do all that stuff btw and more, with FPGA you can even have feedback ...

I mean looking into buying that TV. I actually live in Colorado about half the time, so I might actually be able to save on shipping costs and just pick it up!

I will have research the LaserVue system more, though. In a perfect world, you could just feed it a mirror video input, and use the laser scanning unit inside as-is for a projector!

Even 5mW lasers are harmful for the eyes if pointed directly to them. 2.3 watts is even cooler!!!

I'm not a laser specialist but 3-LCD, 3-DLP and 3-LCoS also need to assemble pictures from 3 sources, so it seems surprizing to be that it would be so difficult to assemble the 3 lasers from the same kind of trichroic prisms as the ones used by other projectors.
Divergence is always present with these projectors but 3.5 metres away it's about one pixel overlap on my 3-LCD projectors.
I find it difficult to believe it would be that hard to converge these lasers just centimetres away from the mems unit well enough.
Or to find tricks around the issue (use a larger mirror, use an array of mirrors, add manual or automatic precision alignment screws)

(again I'm not a specialist, I just assume stuff)

wow:

I guess you'd be very interested in checking what fermilab and cern (among some others) are doing.

Can someone pass the popcorn.

Like this?

Were gonna build another DeathStar. Okay, I'm onboard with that.

It will work.

Actually, we will need to build 3 DeathStars. One red, one green, and one blue.

Put down that pop corn!
I want you to speculate about the Apple TV! Will it be passive? Will it be propeller?

No secret, I hope it comes with propeller...!

...ok,,,,

if you have that popcorn over there somewhere

this guy ,,,, this guy,,, AAAAAAAAAAAAAAAAAAAAA
*agononizes and dies*

I didn't know popcorn was that dangerous. Pretzels yes ! but popcorn...

Dude paid close to half a million dollars to watch 2D content with real-time automagical conversion?!?!?! Damn, if I had that kinda money I'd build THE FRIGGIN' MATRIX!!!!!

Well I think 3D Blu-rays on my home 50" panasonic plasma look better than my local theaters. And my local theaters use high end Christie DLP tech. But I have no way of proving this through links or other technical specs. But it is my honest opinion. And last years LG 3D displays were dissapointing to me. I cant say for the new passive displays. Though I'd like to here good thing about them.

cheers everyone

Yes, the big screen 3D HDTVs look far better than the movie theaters. I have watched clips of Avatar on a 60" Panasonic Viera, and also a number of movies on a 60" Sony Bravia (Meatballs, Alice, Shrek, etc.), all movies I have seen in the theater and they looked better on the HDTV.

with plasma, brightness is so low, I wouldn't call that white, white.

Same thing really with silverscreen projectors, thats not really white, at least some meaningful figures.

RGB LED , properly excited phosphor ( no plasma), laser... That's where it's at.

FYI, today's LED TV's monitors arent white either, cheapo LED's have way too much blue spectral stuff going on , hence ppl bitching about it.

Most newer LED backlight based TVs these days are pure white, probably even closer than your average metal halide projector lamp. The "blueish LED" problem only exists with cheap LEDs, TV backlights most commonly use very nice LEDs that are manufactured by Nichia, and they are engineered to provide nearly flawless white light for most of their effective lifespan (Which is in the 10,000+ hour range, minimum).

This can be improved with pulsed operation, Phlatlight leds supposed to do 100.000 in pulsed operation , and maybe 20k in constant lit up mode. So hold operation is bad, again. ^^

Blue stuff: theres a guy here ( console gamer) , went out and measured TV's input lag and stuff, each he could find, and he said each is blue.

He wanted to buy LCD, admitted these are time machines, went with plasma, went mad because phosphor burn in, I don't know what he has now! Fun fact: serious tekken pro-players still use CRT.*

Yes I saw papers about white LED's, they used nanotechnology, looked decent! I don't know if cheap LED's are any decent, but LED TV manufacturers are reusing CCFL nowdays anyway.

Maybe Apple can afford those cool LED's, but I'm not sure I want to afford anything with colorfilters.

nice CRT there too. BTW Im building speakers like those ATM.

bought LG D2342P-PN posted a small review for those interested here -> viewtopic.php?f=116&t=13125 after 14th post & next.

Probably gonna give this monitor a try since it's available from Walmart and I can return it in 2 weeks if I don't like it.

Since you only see half the normal resolution per eye do you get better performance/fps than full resolution solutions like shutter and anaglyph?

I just ordered this monitor from Amazon.com. Their free shipping seemed faster (expect monitor by mid to late next week). Will be nice to be back to real 3d. Had an IZ3D monitor that burnt out about 9 months ago. As much as I liked to IZ3D community, I was very disappointed that the monitor only lasted 2.25 years. I expect more from a monitor that that. Look forward to how this monitor compares.

I've got one of these coming tomorrow. It'll be my first 3D display, as well. I love the effect on 3DS, and I'm hoping this'll blow me away even more.

Internally I think it still renders 2 full views. It just throws away half the pixels so performance is the same as anaglyph/page-flip/etc..

@ neol
Sweet informative review!!!

As FPR is always on ( Its Thin Polarization Film which continuously polarize interleaved lines ( as i understand FPR : correct me if i am wrong!) and you can see some criticism in link below

http://www.hdtvmagazine.com/articles/20 ... iewing.php

my few questions are

1) How different this monitor looks in 2D when compared to normal LED monitor? is it grainy? can you notice lines even when 3d is off?
2) How much light is scarificed in 2D mode? compared to normal LED?
3) How is your experince in gaming? say Avatar or Crysis2 or Batman Akhram Asylum?
4) Is it not difficult to adjust as hight adjustment is absent?
5) Does it look satisfactory form 50 Cm?
6) How are pop out effects?

Hope given so many questions doesn't trouble you much

Thanks in advance
Regards

Ever saw DLP ?

I bet schools have 3d DLP.

Maybe make two DIY silverscreens , not only one, sell them a silverscreen and try DLP too while you re at it.

And what does DLP have anything to do with this LG monitor?

first in first the link does not say much except for "sacrifice of light" thats it. the same does not apply to this monitor. probably the reviewer made an assumption having an extra layer on display will reduce the brightness/quality of the picture.
don't believe everything u read on net or reviews say. Most of the reviewers don't know wtf they are writing and secondly they write up reviews based on assumptions on product site/other reviews unless someone manually checks the product and puts up a decent review of the same exact product provided with proper settings & other stuff.

personally I don't see any sacrifice made in 2D mode. Infact I had to reduce the brightness while watching HD movies or gaming & in dark the picture is even brighter.

Thank you!!

Have seen demo of LG 42LW5700 Cinema 3D TV just today at store.

Ironic we have LG 42LW5700 availble in india and not D2342P-PN Monitor? That too at ridiculous price tag (2043 US$) 'LG' Bad Policy...

Yes, for TV its really amazing! product demo video shows some clips of street, a dog & Frisbee play
some clips of Opera and yes confirmed there is no light sacrifice good Z+ even better to Active shutter systems

You can notice lines in green and light colors in particular but must be beacouse HDMI cable only supports 1280X720P hence on 42" its understandable to notice lines but it was light on eyes no strain 'good product' - sheds are little shabby(No good build quality)

Think all must be same with monitor too
