line interleaved is a half-resolution method, as is tb, sbs, and checkerboard. that means that both L and R views combined take up the same bandwith as 1080p or 720p stream. 1080i is field sequential whereas line-interleaved displays both views at the same time, ALL the time.

It can be either HDMI or DVI, since it is basically just a regular 1080P image. The issue is with 1080P frame-packing, which is actually double 1080P resolution. Interleaved combines both views into one frame (aka frame-compatible) so it uses the same bandwidth as a 2D signal.

Hdmi 1.4a already has stereo 1080p 60Hz support via frame packing, it's just not mandatory.

Hi buddies, I wanna buy this monitor, but my question is: will it work with xbox 360 (eg. Crysis 2 Side-by-Side via hdmi), will it convert sbs to the 3d?

Finally purchased D2342P after spending really lot time in search for good product + best price
Indeed good monitor and i am able to buy one at 280US$=INRs which is best deal i could ever get in INDIA

My Few findings:

Decent view angle and yes it really requires you to be 60Cm away from monitor to get best 3D effects so you require to seat little away from monitor.

Very light monitor but little wobbly on stand (still it does not collapses though it makes you fear so) screen is non gloss,Provided shades are good for regular ones. clip-on should have frame around glass (Zalman is good enough here).

Yes you can notice small lines when you are say 20 Cm near to screen (Approx ) ( some thing you might have seen with PS2+34" CRT TVs) but nothing practically killing joy if you seat 60Cm away they are barely noticeable. Nothing like 1/2 resolution kill joy of 3D as you got to see it to believe it (Specially for those who think half resolution is worst for 3d Gaming)

All demo photograph displayed very good 3D effect for videos well best i found that displayed gaming demo (Lots of +Z depth LOL!)


@ Cybereality, Blackshark
I have small confusion now:
My system i am going to build for this is as follows:

Intel Core i5 2400 Pr,MB-DH67BL,Ram Corsair 2X2GB DDR3 1600,1TB WD HDD,Sony DVD RW,

Which graphic card well perform better with DDD Drivers

1) MSI NVIDIA Geforce GTX560 Twin frozer II 1GB GDDR5
2) ASUS RADEON EAH6870/2DI2S/1GD5

In past when i had P4 1.6 i have noticed that DDD drivers & IZ3D drivers use to do lots of mess with NVIDIA forceware installed ( I had Geforce 6600 forceware 94). when i use to turn on DDD 3d (Interlace mode) in Titan Quest it automatically turns on Anaglyph3D of NVIDIA. IZ3D never been friendly for me.

also read so many things about AMD HD3D does Radeon now more better with DDD & IZ3D Drivers but fairly i don understand much HD3D. Even if i go to ATI path most of review shows GTX560 has more firepower compared to 6870 so i don want to loose Even for non 3D gaming

What will be better choice ???

If you are planning on using IZ3D/DDD then compatibility should be the same with either Nvidia or AMD. DDD used to have issues with the Nvidia driver, but that has since been fixed. Personally I would go with the GTX 560, simply because I have been die-hard Nvidia for years. But I'm sure the 6870 would be adequate as well.

Hey, I got a quick question.

I also got the D2342P-PN and hooked it up to my machine on the DVI port. For some reason, I can't get the 3D feature to work. The 3D-Mode selector in the OSD-Menu, where you can usualy select if you have a line-interlaced or a side-by-side 3D picture, is always disabled and grayed out. No matter what I do. I also did a factory reset but that had no effect.

I tried to contact LG support but I haven't gotten a response in two weeks now. Now I am trying to get some help on the net before I will return it to the store.

Thanks for your help in advance.

You have to connect your monitor to PC by hdmi, after that 3d-mode selector will work. It only work when you are using hdmi port.

Its a passive monitor. You don't have to "enable" 3D. Its always on (its physically part of the display). Just put the glasses on your face, thats the 3D mode. Then use software that supports interleaved mode (iz3D, DDD, Stereoscopic Player, YouTube3D, etc.). You can also use an HDMI 1.4a source, like a PS3, and that is likely what will enable the "3D mode" but the quality will not be any better than feeding it an interleaved 3D image.

Does anyone have issues with 24p? It seems to do a nice job (it even seems to flicker the backlight) but I have serious sharpness issues - it is all pixelated and ugly almost like it is only rendering half the pixels (in 2d mode). Swapping 3D mode improves things but makes it just as blurry as normal swaped l-r is. I tried manually adding 48Hz and it works correctly but HDCP doesn't seem to work and I just get a black screen when trying to play a blu ray on TotalMediaTheatre 3. I don't care too much about 24p (never bothered me on my old monitor that didn't support it) but it would be nice to have it working - all other refresh rates apart from '23Hz' (23.976) /24Hz work correctly; though the de-interlacing is absolutely terribly on interlaced (seems to be a particularly bad simple bob).

Using NVIDIA 275.33 with GTX 460, on a literally fresh install of Windows 7 64bit (just reinstalled windows a few minutes ago for other reasons). Not sure whether the screen is defective or it is a driver or compatibility issue (unfortunately don't have an actual blu-ray player to test).

If you play at Blu-Ray 3D in 1080P mode over HDMI, then it will be at 24Hz. Not sure if that works in 2D, though honestly I've never noticed 24P mode looking any better.

It would appear reinstalling windows has made 48Hz suddenly work properly which pretty much solves the problem. Still interested if anyone has/doesn't have the same problem as me with 24p though.

edit: Interesting quirk - HDMI 3D mode with 3D-2D on works fine as a 2D mode. Only normal 2D 1080p24 doesn't work - weird. Been having some strange driver issues with 3D mode (1080p 3D mode wasn't working I had corruption at the bottom of the screen and was in general competely wrong, and even caused the monitor to stay on black screen and freeze (even power toggle took like 30s) until I unplugged HDMI and changed the setting when I tried 3D-2D. Suddenly it is working now after changing resolution a couple of times. I'm hoping it's a driver issue - unfortunately don't have a hardware blu-ray player to test. Still, knowing HDMI 1.4 3D mode is working is nice if I have something to use it with other than the PC in the future.

It's $300 right now so it's definitely a cheaper alternative to active monitors. I just wish 3D drivers can just render the scene half resolution and stretch it to save performance.

this pc here struggled running unreal engine3 games with acceptable frames in 3d ( 60+ per eye) , when I tried the 2233RZ for 30min, also it looked washed out that was my biggest complaint against active ( not knew they are limiting duty cycle of the display, so every , every single spec is overspecced & crap) ,

Then, I went with DLP. Really, the same PC runs every single game I throw at it, even metro2033 is absolutely playable, and the resolution.... The resolution stuff is whole different ballgame with DLP. Theres no better trade-off for high FPS vs. spatial resolution than DLP right now, really, this is HD, especially at 120hz, averaged between two eyes, its mind boggling how good DLP is, can't wait to see other LED / laser technologies.

Really, you should think about buying into these pocket DLP projectors , LED or laser, and a suitable rear projection dark screen would do the job instead of monitor IMO. You know rear projection stuff right?

My parents have two rear DLPs at home (40" and 70"). They are really cheap for the size but it's just too bulky for a college apartment.

Also, I prefer passive solutions since I have glasses and I understand that DLPs are active.

That option works only when monitor is connected thru HDMI cable. Its meant to be grayed out in DVI connection.

Your monitor is not faulty, the option is not suppose to work in DVI connection mode. BTW I have same LG Monitor.

for 280US$ ?? from where and how are you buying that ?

@Neol: Its not 280US$ its iquivalent Indian Rupees (280x47=13160 INR)
I have purchased it from LG IT Product Disrtibutor in my hometown (City: Ahmedabad State: Gujarat) in INDIA-not online

I like to know from those who use ZALMAN does this monitor have Active Barrier (electronically controlled just like shutter glasses) barrier? Thin layer before LCD which saprate left and right eye view or its passive barrier like fix film of LG D2342P which is always on

dilip, can you post the contact information here ? (email/phone)

Its just matter of time you can buy it even cheap from amazon now

its just 264 US$

So don be surprized
Its just normal LED + Thin mircro film with horizontal interleaved lines of different polarization

it must be even cheaper for LG in mass production
And soon it will be cheaper for us all !!! cheears!

I have noticed one strange phenomena

With EA’s Lord of the Rings BATTLE FOR MIDDLE EARTH
(EA RTS-based on LOTR)

This game runs pretty smooth with DDD drivers and I played it in 1280X960 resolutions with full screen mode still it looked very nice and I enjoyed good 3D depth

When I tried to play Avatar even at 1650X1080 resolution (So that I can get smooth frame rate I have still not purchased graphics card and experimenting with Core i5 internal graphics-Intel HD 2000) the 3D image was kind of “3D with Multiple Gaps” I can understand as this monitor have Fixed Micro Film it naturally does not support any resolution other then native full HD if you wish to play full screen

Then why this does not applied to BATTLE FOR MIDDLE EARTH

Avatar is a native supported game and must be played in native resolution (1920x1080). The DDD driver can dynamically scale games from different resolutions to 1080P (or whatever else the monitor might need). So you are not limited to run the game at native resolution, the DDD driver will upscale. Also, do not try to launch Avatar from the DDD launcher, since this will go into double 3D mode and not work at all. Just open Avatar normally and select "line-interleaved" as the 3D option.

Also, $264 is a nice price. I may have to pick one up.

I managed to figure out that my HDMI issues (blurry 23/24/30Hz) are definitely an NVIDIA driver issue. Working around all the other hideous bugs in newer releases of the NVIDIA driver (needing a custom resolution to have actual RGB 0-255 levels regardless of setting), a custom resolution of 1080p @23.976Hz works perfectly with no blurriness on driver 266.58 (not suggesting using that version as there are horrible bugs with resolution/refresh rate changes in the control panel being completely screwed up). The black levels are still not auto-set correctly on the display but I have had that working previously on 275.33.

At least now I know the monitor works correctly - it is just the drivers that are terrible. To think I switched from ATI because NVIDIA had more stable drivers! I don't really care enough about 24p to suffer through the about 5 steps to get it to work each time, so I'll just wait for the next WHQL driver and see if that fixes the problem.

The monitor is going about $250 on Newegg right now It's open box though: http://www.newegg.com/Product/Product.a ... 824005254R

^ Open boxes are all gone ... the price fluctuations on this monitor are odd. New pricing of $264 to $300 to $349 and back to $300 in less than a month.

I still can't decide whether to go this way (passive) and spend $40 as a NVidia card owner for iZ3d for the one title (iRacing) which does *not* work with DDD, or save $ until I can get the Planar active-shutter + glasses (or if it's good enough, Viewsonic's V3D245) and use the 3d Vision driverset.

(DDD doesn't work with iRacing because iRacing doesn't launch the executable directly but instead uses a web page to invoke a local service which in turn calls the executable; I believe this is a convoluted but effective anti-hacking technique ... important when the top oval and top road-course driver will win $10k real cash each).

If you have the money, the Nvidia 3D Vision is probably the better route. I mean, I bet this monitor looks great for the price, but its not going to be full 1080P. More importantly, the viewing angles will be limited, which can get annoying at times (especially if you use a racing wheel and may not be sitting completely still). But if you only have $300 to spend you probably won't get a better deal than this.

I bought the LG DM2350D monitor/TV recently, but returned it because there were annoying vertical scan-type lines visible in 3D mode whenever there was movement in the picture. I also spotted these lines during a store demo of the LG D2342P monitor. Has anyone else seen these lines?

I'm surprised to hear about vertical lines, didn't you want to say horizontal black lines, which should be normal with such a technology ?

@cabot001: This is a little confusing to me when you say vertical scan-lines. I guess you mean horizontal, since these are horizontally interleaved monitors (FPR). But this is a passive display. The lines are always visible and static. They should not be moving at all, or be effected by moving images. I think what you mean to say is that you saw aliasing artifacts, which appear as jagged edges. This is sometimes called a staircasing effect, which can be strange to look at. Is that what you are talking about?

Thanks to Cybereality and Fredz for your quick replies. No, I didn't mean the alternating horizontal black rows of pixels that are visible on a passive 3D monitor. These are faint vertical lines, evenly spaced that appear in 3D mode whenever there is a reasonable amount of movement (e.g. a character moving across the screen or a panning shot). They are spaced a lot more widely than the pixel spacing, maybe every 20/30 pixels or so. Perhaps you could call it banding? Anyway, They were definitely there on the DM2350D that I bought and on a D2342P monitor I saw in another shop. Maybe these were from a bad batch or maybe it is a motion artefact problem that is present in all the models that may be put right with a firmware upgrade. I know that another 23" LG 3D monitor will be available soon with an IPS display. I shall be checking this one out as soon as I can with a view to replacing my 22" Zalman.

Interesting. I'm still not sure I understand what you mean, but I believe that you saw something. Don't think I've ever seen that though.

Exactly the same reasons, why i selled my Zalman!

Hey Guys, so I am planning on buying the D2342 P, I did a lot of research and your forum helped a lot too. Went through the entire blog. Does anyone by chance know where this product can be tested before being bought because all I see are online retailers on amazon and ebay and newegg. I am from ottawa and its surprising that theres no retailer that carries the monitor. Also a couple of quick questions, I have heard mixed reviews about the monitor, worst one being the cnet review but i never trust those idiots.

1) I was wondering if I can hook my xbox 360 to it and play gears of war 3 or crysis 2 in 3D. Also, since i have the pro version that doesnt take hdmi out, can i connect vga and get a decent 3d experience? If not, will an xbox 360 elite with hdmi out port work instead?

2) Also for my PC, i have an ATI HD5570 2gb in crossfire, does this gpu have to be compatible with hdmi 1.4a or will my set up work with the iz3d driver?

3) Final question, is the 2d to 3d conversion decent, I mean could I watch say Fast 5 with the iz3d 2d to 3d media converter on lg's 2d to 3d mode and have a decent experience? Thanks a lot guys, any help is really appreciated.

I own this monitor from last 2 Months

2D to 3D conversion is subjective what you wish to see
some movies look decent while others just crap!

Overall experince is mixed bag
Its not so satifactory as it sounds.
you can judge, if you see both real 3D and converted 3D
I have seen Avatar Converted and Avatar Actual 3D both on
this monitor and i bet actual is 100 times better to converted.

Converted 3D is like 3D Fantacy kids book, where you open the book and 3D castle apperas in front of your eyes.this is done by simply cutting and adjusting pictures at differnet level. i hope you got my point

some thing which is not shot in 3D can not be converted to perfect 3D at least in live striming ( by using Normal DVD+Conversion Software)

Though latest sofware do little justice. overall it looks FAKE (in most cases)

so for 3D conversion i would say don Make this your purchase decision factor.

Other wise monitor is really value for money as DDD gives excellent result with Most new popular games and its not too tough to be in good viewing angle.other side Passive glasses are really comfortable you can play more then an hour or two without eye fatigue.

I am planning to buy LG D2342P monitor for 3d design/development , Please advice me which display card is better suited ?
is Nvidia GetForce GTX-560 good for this monitor ?

Thanks
Kiran

Electronics Expo has the LG D2342P-PN 23 inch Passive Cinema 3D LED LCD Monitor for $264 - $51 off with coupon code BIGBEN + $20 shipping = $233 shipped.
I picked one up finally. Too bad they offer free shipping through Amazon, yet on their (Electronics Expo) page shipping is $20. With free shipping that would be a sweet deal at $213! I'm thinking of bothering them to refund the difference.

Scratch that.

Passive 3D is really nice for TV sets, since the drop in resolution probably isn't as noticeable at a distance, and the ability to use clip-on 3D lenses is a much larger plus for a TV. People like me with poor eyesight have no trouble using active shutter glasses with a PC monitor, since you obviously have to be close to the screen in that scenario, and therefore nearsightedness isn't a problem. When it comes to TVs though, I NEED to wear my prescription glasses to order to make anything out on the screen, which is pretty much impossible to do in combination with active shutter glasses. This won't apply to everyone, but for people like me, clip-on passive 3D lenses are a godsend if you go the TV route.

The only reason I could give for recommending a passive 3D monitor is how much cheaper it is compared to the competition. I believe this is the cheapest 3D monitor you can get on Newegg right now, so if you REALLY need to save some money, this is an alright choice. Personally, I recommend always going active 3D whenever possible when it comes to PC monitors.

I'm thinking of getting one of these but i still have a couple of concerns. The manual says that the 3D mode only works over HDMI. I have a computer than can play 1080p interlaced OK and is HDCP compliant with my Panasonic AE900 but I only have DVI output. I'm using a DVI-HDMI adaptor to output to my projector. I wonder if I might have some issues with this The fact that my nVidia control panel says that my output is HDCP compliant makes me think that I might be OK.

The other concern I have is that if the 3D only works over HDMI then I won't be able to use it via D-sub from my Laptop which I use for the net and YT3D clips etc. I read that the interlaced screen must be fixed if its for passive 3D but I'm wondering if over D-sub and DVI, the monitor somehows stays in 2D mode and only shows a side by side image. They may have some way of doing this and so it might limit the usage I can get from the monitor.

Thanks for any help

Right, I looked at the one at the store near my house once again, and this time I did notice the _vertical_ lines (yes, I'm not talking about the horizontal interlace lines),- the best that I can describe them is that they looked like faint vertical nonmoving scanlines - the demo setup was running a video of a game road of some kind and the lines seemed to be visible towards the sides where there was more motion - but I can't really confirm that as it could be my polluted judgement from reading this thread. It's really hard to decide- they weren't a "killer" or an obvious defect, but I don't recall seeing anything similar on the zalman 3d 24' when I had it for a few days before I returned it.

Are they present in all displays?
