However, when connecting the monitor using HDMI - HDMI connection, ghosting is so profound and annoying that it even interferes with 3D perception.

This happens with the Tridef driver provided as is on the LG disc that comes with the monitor.
I have fiddled around with the TrifDef software but it seems the software recognize the 3D mode used using HDMI (line interleaved) automatically, I also tried to changed 3D modes using the monitor options to no avail (the picture just got messed up in wrong modes), and the 3D depth option in the TriDef software.

Could somebody provides some insights as per a successful setup for the LG D2342P? I am really interested in buying this monitor and it saddens me to see this bug.

Hi,
As yuour using tridef for lg i take it your tridef experience starts off with the flowers?
Is the red flower and green stem ghosting?
If so can you please take a picture through one of your lenses and post it back, it will show us exactly what your issues are, if not though just take pics of your issues, pictures must be took through a lense of your glasses

Hi there,

It's a monitor at the mall so it's not very convenient to take photos. However, I recently found out the root of the problem actually was not the HDMI connection, but the very limited vertical 3D effect limits of this technology, the monitor was set up a bit below might eyes, that was why the images was off. When I used the angle adjustment axis behind the monitor and set it such that the center of the monitor is on a plane with my eyes, the problem was much reduced. Ghosting is still there, of course, but at least it does not interfere with 3D experience as much.

I have included 2 mpo files for testing using the tv's usb media player, these are pictures.
Both work 100% perfect for me with zero colourbug, so the tv's do play interleaved and checkerboard!
Just not correctly over hdmi or vga for me.


Edit
File factory sucks goto my avforums group to get what you need.

A standard Checkerboard tranmission video file dewigned for DLP RP TVs contains two 1920x560 fields which are created (sampled by selecting every other pixel frome a 1920x1080 frame). These two fields are merged together together into a single 1920x1080 frame. At projjection ime the 1/2 of the pixels which were deleated by the sampling are invented from the adjacent pixels to create 1 1920x1080 frame for each eye. This format is NOT a mandatoy HDMI 1.4a format like the SBS and TNB formats which are listed earlier is this thread.

For some reason those files are always unavailable at this time.

A good way to test for elimination of whether the picture viewer is processing interleave and checkerboard correctly vs output in hdmi is to test a native interleave and checkerboard image and output the result in the LG's picture viewer and see if the problem shows up.

In the meantime since I can't access those files, I am going to add my native interleave pictures to a usb and see how those pictures look in the LG picture viewer of the HDTV. Hopefully they support jps files which are jpg side by side files.

Major news.
A couple of things
Those mpo files are viod!
An mpo file is a standard 3d format like hdmi 1.4, a mpo file will autoswitch your 3d on and the image contains 2 jpeg images sbs or o/u ( ??? ) so the whne i thought i was creating checkerboard and interleaved mpo files they was really being converted back into a sbs mpo 3d file!
This is why the tv played those mpo files perfectly so test is viod !!!!

Something big!
So big infact it does 100% prove beyond a shadow of a doubt that lg tv's have bugs that lg does not recognise!!!!

The clean png images for checkerboard and interleaved have colour ghosting using an external media player that i brought just to test, i can prove both images are clean as i can do the edid mod and get interleaved working 100%!

I went and took my native interleaved files and made one copies of jpg and png versions. When I ran the LG picture viewer in the usb slot, all images had terrible color ghosting in them. The only way I was able to get good clean 3d images was looking at the images directly in Windows 7 with Windows Photo viewer with my Standard Settings in my guide correctly calibrated and viewing it with Ctrl-alt-0 to view actual size of the image.

Some notes, a highly compressed imaged increased the color ghosting even with my settings in place. No compression jpg was equal in quality from a ghosting perspective to png in Windows Photo viewer.

This further proves that LG needs to evaluate their Interleaved calbrations more thoroughly in addition to what you mentioned above butmuncher.

I even tried modifying the standard settings in the LG picture viewer but it did not seem to help. This needs to get fixed because LG has a partnership with Tridef in supplying Native Line-Interleaved 3D stereo format to all their ranges of monitors for gaming and if this does not get fixed it will affect everyone.

Yeah i know Skyguy3d, we both know but can't do 1 thing about it!
I'm again on the mission, a mission of getting followers to our march but tobe honest it really is'nt going anywhere, it's so bad i feel like a spammer lol as trying to get the community involved is a very hard trick indeed.
Skyguy3d if you can think of a way to get 1000's of people in the lg colourbug post i'd be gratefull as that's what it's going to take to get lg to stop dismissing us.
I bet there is only about 30-50 people that have mentioned they have the colourbug, this includes random people that have tested for us and confirmed and they are all strewn about in different threads, trying to bring those together would be a good start.

Well LG lost a sale from me, when I returned it I opted for cash versus an exchange!

I opted to go back to gaming ghost and lag free on a projector.

Interleave is the Flagship Format of passive 3D, yet as much as LG screams buy passive, they can not perfect it on their TV.

Good to see you are still fighting the fight, so many times one person is all it takes to make a difference.
post #400 of 513
Well well well LG!

Sort your life out as i now no longer advise anybody to buy your 3dtv's!!!!

I have just come home with this toshiba passive
TOSHIBA Regza 42VL863B 42" Full HD LED 3D TV buy online | Currys

and will be picking up a free bluray player in a couple of days for free after i asked and i got!

AND

There is no colourbug in interleaved 3d, it plays as it should 100% perfect!!!
The set does'nt have a checkerboard 3d option but it is no longer needed with interleaved working.

I advise anybody who has the problem to demand a full refund and get a toshiba passive or something with none lg firmware but only if you really do want a working interleaved set! But take this with a pinch of salt as i havent tested this toshiba out yet, will take a few days to say if its any good or not.

I can't comment on it's performance yet as i have only tested the interleaved as working without any edid mod or anything.
Will play some dirt3 later and test the motion handling in 3d gaming.

I sold my lg passive, 2 months old and did'nt lose a single dime but had to pay £50 more for a tv with more options, more hertz and a free bluray player, i can't grumble as long as it's a sound tv but its only been on for half hour so time will tell!

That sounds cool, I wonder what the equivalent toshiba is in the US? Now my question is did this tv work with interleaved right out of the box with stock firmware or did you have the firmware updated before running the test?

Yes mate straight out of box interleaved worked.
After installing my new tv i de-installed the monitor driver and scanned for new hardware and rebooted.
The edid looks sound and even says what size my tv is, lg never said this!
So i am happy now, what a waste of time my time with lg was, it really did ruin gaming for nearly a year for me.
Works over vga and hdmi with no sharpness tweaking, IT JUST WORKS!

Can't find any firmware so its stock firmware allso.

Than this proves that LG has faulty PC HDMI and VGA output that causes this abnormal ghosting in interleave and checkerboard. In addition, there is an underlying mode that the TV needs to be adjusted for because when using native interleaved pictures in the LG picture viewer, I can see ghosting that is unremovable in this native display viewer that you can use when viewing pictures. This is incredible that LG has released the 47LD950 one year ago, the LW5600 and LW450 6 months ago, and now the current LW9800 that are all suffering from this ghosting and they still haven't had a fix as of yet and the only question is when was the Toshiba released to manufacturer. That's not even mentioning the checkerboard problems LG has on its plasma end that suffers from checkerboard color ghosting from incorrect calibrations too with the LG 50PZ550t.

Toshiba must of added additional tests to ensure the integrity of their picture quality during calibrations which is why you are getting the correct name of the Toshiba TV becoming detected straight in Windows 7.

Now it's just a matter of running all those tests I've gathered and see if you can also get clean ghostfree pictures in Toshiba's picture viewer and with your HDMI external box viewer.

I'm also curious how 3D processing like Side by Side and 1080 24Hz affects the lag with the Toshiba Passive compared to the LG 55LW5600.

in 24p this tosh is not as smooth as the others i've had, it very well be a issue, a major issue but maybe something i can accept as all i ever wanted was 3dvision at 1080p and i have that.
Dirt 3 played same as it did on my 450u, about same perfermance, possibly a few % less xtalk than the 450u.

Dear Butmuncher,

Have you test any games with the Regza. As far as I know, LGs TV have input lag problems in all 3D modes for games but line-interleaved. How does the Regza stand up to this test? Please test with some first person shooters.

Also, please check whether you can get up to 60fps (60Hz) with 3D Games at Full HD resolution.

Thank you!

Hi i have some very good news for you and the lg lag issue?
Setting lg to pc input usually romoves lag, well that what i thought, there was a little bit of lag still and in 3d mode this was amplified because of the 3d proccessing.
Even in interleaved mode there was still a teeny bit of lag but it was nowhere near enough tobe noticed and i could race online as a good racer with the pc label and game mode, turning pc label off would make racing uncontrollable due to lag so this proves there was alot more lag.

This tosh is alot fastr than any of the lg 3dtv's i've own, can't comment on the plasma i had as it was turn it on turn it off take it back type thing so i cant remember.
My racing, and i'm an ok dirt 3 clean driver went from very good to driving like a noob, i drove into every corner too early for about an hour and the rest of the night i was like a baby learning to walk again.

A few things to note.
Toshiba and desktop mouse moves extremely fast, i can full lock my wheell in cockpit view and full ock it the other way back and forth at the fastest speed i can and this is translated on screen exactly as fast as my arms can go!!!!!!!!!!!

No lag, lg does have lag but it was'nt that bad and tome was 100% ok but now i can see that something has happened in response times and it is very noticeable while semi-pro racing.

Tested with battle field 3, same as racing zero lag, or what feels tobe zero, as i thought it was ok with the lg's i've had.

Yes i get 1080p60hz60fps 2d and 3d gaming.

I had commented on the films not being upto scratch, that was a settings issue and i am now more than happy with both interleaved 3d gaming and films, i finally have what i've been searching for for 8 month and 4 3dtv's, a good xtalk free image, no lag and 3dvision 1080p!

The last few week i have put about 3-5 hours most nights into online racing with dirt 3, my skills are good enough from my time at the wheel and pedals so the lagless response from the tosh was overwhelming at first, i literally could'nt drive!

So it sounds like Toshiba

Pros
-Lag response time is better than LG
-Interleaved 3D can have ANY sharpness setting with no ghosting

Cons
-No checkerboard support

vs.

LG
Pros
-Kpop channel with Kara and Girls Generation in 3D Live

http://whylgtv.lge.com/archives/3468

Cons
-Sharpness setting is locked in PC mode for users outside of US
-Checkerboard has extreme color ghosting that is in passive 3d models ranging from one year ago to all current passive 3d tvs

If only I had time to rearrange my tvs around, maybe I would add a toshiba to do all this testing. And someone would have to pay me for my time

Oh yeah, just recently I bought a season pass to IMAX 3D films so I can watch movies as many times I want on a humongous screen and I gotta say the 3D technology of the present for what we have today with passive displays even at 540 lines of information looks pretty good compared even to large projector screens. I see problems with the IMAX screen in which I can discern compression artifacts because of the size of the encoding. Also the IMAX 3D screen had problems with 3D in dark scenes which is common with my previous experiences with older 3d technology. In a way, the 3DTVs of 2011 have achieved much better crosstalk and ghosting reduction that have made entertainment in the home in some ways even better quality than what you would have to pay 15-20 dollars in a movie theater.

Judging from the light and dark 3d scenes, the tvs of 2011 outperform the ghosting qualities that are needed in games where the 3d content is generated in real-time with no ghostbusting algorithm or workup to remove artifacts in movies.

Also I noticed the best position to sit in a IMAX movie theater is not in the front or the back, it's right dab in the center of the movie theater to achieve the highest popout and immersion due to the high slant angle of the chair configuration.

On the other hand, the best position for seating that I prefer watching or playing games in 3D on the passive screen is at 4 feet away, and I get less immersion sitting far away nowadays.

We will see how 2012 affects the 3D industry but it terms of quality it has definitely surpassed my expectations being able to watch each comparatively speaking.

One thing you got to love about the Toshiba, looking at the firmware update page, it still shows the previous version, so you could probably roll back if desired. It also, get this, shows release notes!!!

I miss my LG at times, if only they would have fixed the bugs. Oh well, I've got to say I was having a dificult time getting past a particular Boss in a game on the LG, but was able to breeze thru without the lag on a DLP projector.
post #410 of 513
Yeah the tosh has really shown me how bad the lag was.

You guys that really want interleaved and lag free gaming will be pleased to know there are sets out there that work with no issues.

But....
This may mean something big.
If you are thinking of upgrading from a lg to one that you think may not have no colourbug then check your lg's service menu first!!!
This was a big deciding factor...
In the service menu you will see all the other manufactuers that use lg's firmware, toshiba was'nt listed in my service menu which gave me alot of hope of a tosh working, and it did work!
I did not want another brand tv with lg's firmware as it's base.
While in the service menu to not feel scared to browse all the other manufactuers, just remember the one you started with though
I was fool for changing many many settings in the service menu as i could of killed it but my quest for fixing the colourbug led me todo things no mortal man would do with a £650 tv lol.
Many settings messed the screen up but the service menu was allways sound so i could change settings back but be carefull none the less!

3dnewb wheres the tosh firmware page?
Thanks.

For everyone that is still within the one year warranty of LG's warranty, I suggest getting in contact with LG customer service to let them know that this issue with Line-Interleaved 3D is working 100% on the Toshiba Passive 3D TVs and has now been fully resolved by moving to the Toshiba FPR. I am giving them 2 months tops to fix the issue and then seeing if they can pull something off.

If they could fix this issue, then they could fix checkerboard probably all at once too and I have a feeling that this problem may not be specifically isolated to the LG 3d engineers but will need to involve 2d calibration engineers to fix this altogether.

Post your thoughts on this issue, you may have better ideas than me.

Here here!
I was very lucky, and i take it sadly alot of you guys would'nt be so lucky to sell a 2 month old lg 3dtv for more than it cost in the shop.
if it had'nt of been for this i would of been on the phone damanding a refund from my place of purchase, i should of done this along time ago but...

My first lg 3dtv with colourbug i was gutted with, the shop would not accept the return and refund on it as they had never heard of teh issue, i complianed and was told to go away and i was told it was my pc!!!!
So i lost £100 on that, luckily again i could of lost £300 on it but i have my money making ideas and managed to sell it for more than it cost in a shop lol.

Lg HAVE released faulty 3dtv's and as such you are entitled to a refund now that you have all the evidence you need, espicailly with th tosh evidence!!!!!


Thanks 3dnewb, sady they are not uk firmwares

I have included the tosh's inf on your inz3d edid thread skyguy3d .
I tested the faulty edids but they work on this tosh.
Infact i have tried random edids, all work fine.

Ahhh, I finally went and bought Tridef and I gotta say some of the fancy customizations you can do make my Sonic All Stars game pop out even more than IZ3D. Even Ghostbusters has better particle effects that really come out of the screen.

The cool part of this software is the autofocus plane has nice adjustments to prevent my eyes going crosseyed and it really knows how to adjust the objects nearby without causing scene changes to mess up my eyes when they change dramatically.

I feel like I just upgraded my video card but only changed the 3d drivers because of the change in perspective.

Another bonus that Tridef has over 3dtvplay currently is that you can play any games at any resolution to gain framerates of 20% by playing lower resolutions and having the 3d upscaled to the native in every game. 3DTV play is forced to run at either 720 or 1080 only so that limits the pixel quality you can achieve with passive or choose slow input.

IZ3D has this too but Ghostbusters would have messed up mouse input controls when using this optimization.

The other nice part of Tridef is that the cinematics are much easier on the eyes to watch with high depth because of limits it places on the separation on far and near objects.

And Need for Speed Hot Pursuit has no shadow problems like it did on IZ3D.
Guys, get the Tridef software, it's that good!

Glad your happy, pm on it's way making you happier possibly for the future
Iz3d really is quite rubbish, i never ever used it apart from every now and then and then it was to test the game as none working usually.
Tridef and 3dvision is where it's at for me, great duo!

And i really did enjoy hot pursuit, was a brillant mad crazy fun game that had my whole body shunting with the car into the old bill ect lol, great game!!!!!

Tridefs fake 3d works very good usually on none working 3d games, fps games though look very bad as the virtual 3d makes artifacts around the gun ect.
Nfs the run looks very good in virtual 3d mode, better than nothing , munu's are alittle wack but once ingame it's ok.

Dear Butmuncher,

Which 3D Mode do you use to get FullHD at 60fps?

Another question is, when using with a PC, is the BIOS loading screen and POST process displayed normally on the TV screen, as I've read that HDMI cannot display low resolutions?

Thank you!
post #417 of 513

Hi sodi,

The bios and all the post process show up on my x58 motherboard. I recall having a game run at 640x480 at one time.

I use Line-Interleaved at 1080/60Hz most of the time for the best picture quality. With the LG though for US, you have to use sharpness to minimize the grey ghosting for PC label.
post #418 of 513
Thank you, skyguy3d. However, the TV I am planning to buy is a LG 32LW4500, it has 3 HDMI inputs but none is labeled as 'PC', only 'HDMI-1' '2' and'3' how can I tell which one will give me the lowest input lag?
post #419 of 513
Sodi: They are talking about the "input" screen you can label what device is on them. With the LW6500s you can label any one of the inputs "PC" or various other devices like Set top box, Game, Bluray, DVD & etc. The "PC" one is suppose to have less lag.

I don't play 3d games much, but I've never gotten my interleaved to look good so I've used side by side mode when I've played with it. Never could get rid of the ghosting, so I'm watching this thread hoping LG fixes it.

Opinions on new firmware?

In a group effort to save LG from embarrassing themselves, I suggest everyone that has the LG passive tv model post wherever you have access to an lg thread that contains information about the LG passive and continue to post your status monthly in the same thread until LG fixes the problem. I repeat, you do not have to post in the same thread that I post monthly.

The fact is, Toshiba has an FPR screen that has none of these color and grey ghosting in interleaved mode. This problem is apparent in both Line-Interleaved and Checkerboard for LG passive tvs.

Only by addressing this issue monthly in a combined effort, is one way I can see us getting good results.

Since this a holiday, I hope people understand what I am telling people to do.

I have already posted my first monthly post in the LG55LW5600 owners thread as a start here
