LG TRUMOTION MISSING - Specific to 42LM, 47LM & 55LM series (excludes LM7600 and newer) - Page 8

I think it's pretty much been concluded by now that depending on how far down the food chain you are (ie lower end models) you just won't be getting a trumotion option available and it's questionable as to if it's even there or functioning at all... It seems SOMETHING is there in the form of a strobing backlight, but that's not really what most of us think of when we think of trumotion and the motion interpolation settings it should come with.

Apparently they are there on higher end models.

From the 47LM4600 thread

Original post: http://www.avsforum.com/t/1437359/lg-47lm4600/90#post_22777426

I just bought an 47lm4700 and I know for a fact that the trumotion feature is not active since I have another LG with 120hz trumotion feauture and can definitely tell the difference. I hope there is a fix for this soon since here in Mexico this TV is worth about a thousand dlls.

Just setup a new LG47LM4600 yesterday. Connected it to Sony 3D Bluray player (BDP-S590) with high speed HDMI cables. When I try to play a 3D movie using the Blueray player, the TV asks me if I want to watch in 3D and I select "OK". Then is shows the movie like this (split screen)




Now, when I stop the movie and restart it, it seems to play normally and 3D looks and works great. Am I missing something or have some weird setting enabled? Thanks!

Frank, I've got the same setup and have had problem getting 3D to work well with the firmware that came with the set. Check yer firmware the latest version 03.40.08 has better support for 3D.

I've got more info on firmware in this thread.

I found it interesting that it was very difficult to get the TV and blu player to correctly display Disney titles. Even after you get the TV and player to display "one" image I was getting what's called cross-talk. The slight ghost image to the left/right of the rest of the image. I tried a LG blu player which did better getting the initial 3D displayed, but still had a problem with the cross-talk.

Thanks. I was holding off on updating the firmware based on some other comments but I think I will give it a try. I have the feeling that both the bluray player and the TV are trying to outsmart eachother and creating an image that I can't seem to watch.

Have you been able to calibrate your TV using the 3D setup options on the Disney disc? When I try to run this and hit the "settings" button on my TV remote it says that option is disabled. Very frustrating. Maybe the new firmware fixes this?

Unfortunately, the new firmware still does not allow you to make changes to the 3D calibration settings on the fly. It appears that when 3D is engaged the TV defaults to the 'Standard' setting with increased backlight intensity. The only workaround is to modify the standard settings prior to starting the 3D movie. The backlight, however, does not appear to be adjustable. Even when the backlight is reduced to '0' the picture is still quite bright.

My TV is the LM5850 and the set came with the 03.40.08 firmware installed. Despite the above stated problem the 3D picture is amazing. Hope the new firmware fixes your issues.

One more point. The passive 3D effect is very forgiving except when it comes to the vertical viewing angle. Try to keep the horizontal center line of the TV panel at eye level. If the TV is mounted higher than this, above a fireplace for example, angle the panel down to achieve the same effect. Crosstalk definitely becomes an issue if these guidelines are not followed.

I just unboxed the 47lm4600 and i think it had like 3.06.07 or around there and I even though the firmware auto update via the tv didn't find anything I installed 3.40.08.


I cant tell a picture difference from the firmware update but man this tv is a great upgrade from my old panel

Any news on if LG is adding this feature via firmware update to the sets? Picked up the 55 and the TV is great but would like to have this option and see that the firmware hasnt been updated in almost 2 months

I'd like to have the trumotion feature too. Actually, i'm having the impression that fast moving full pictures slightly stutter. I would be interested if trumotion would change that. However, a response to a question about it on the lg website says that they have not planned adding it in a future firmware. I guess we shouldn't set our expectations too high on that.

Just picked up the 55LM4600 in the recent Sear's deal.

It's a great price, but I'm really upset by the lack of configurable TruMotion setting. I feel like this is bordering on false advertising. They should not advertise all the models as having TruMotion 120Hz without differentiating between those that have full access to the feature and those that are hardlocked to the LOW setting (it's hard to tell if even that much is true!). That's like advertising two cars with the same engine and "forgetting" to state that one of them has a governor limiting you to 60mph.

Still considering returning the TV over this, but I think LG and/or Sear's owes me something for wasted time and mental anguish.

EDIT: Forgot to mention that I already tried upgrading to the latest firmware 3.40.08 which did not help.

Sears is not to blame, they just sell it. If anything you have to take it up with LG

Well now that I know for sure how much BS "TruMotion 120Hz" actually is. Does anybody know if it's possible to return my TV to Fry's if I no longer have the box? I am willing to yell at someone about this 120hz issue, It really ticks me off. Why hasn't there been a lawsuit for false advertising yet?

47LM4600 here.

The Fry's link doesn't even say "TruMotion 120Hz" just says 120Hz Refresh rate, which is definitely not true.

I spkoe with a rep from LG via chat today and this is what i got out of it....

"So let me clear the air over LG's Trumotion 120hz and why it doesn't look like other brands such as my friend's Samsung HDTV that has120hz. I had a chat session with an LG support rep and they informed me that the LG panels for 2012 all use a specific Backlight method. I forget what they called it, but pretty much what the TV does is throw a dark frame in between the picture which causes it to not have such a "soap opera" effect. So last year's LG 3D models all use a method where they throw in a regular picture frame that's lit instead of dark in between the picture. I asked the rep what passive 3D TV's didn't have this method and she informed me the panels from 2012 all use this "Dark Frame" method, but that panels from 2011 don't use the "Dark Frame" method. Unfortunately all panels from 2011 are active 3D TV's which is not what I want.

I then asked if she had any news on 2013 panels and if they also indeed have this "Dark Frame" feature and she was unable to give me the information because they were only in the pre-sale status. Now I apologize that I don't remember the specific name for this "Dark Frame" method but the rep was very quick to answer my question and if they weren't closed right now I would just pop in a chat session to ask again.

I hope this helps everyone and besides the 120hz feature I absolutely love my LG TV. I got it at a fantastic price of $601 at Fry's which is a steal especially since I received free shipping."


I think it's complete BS and I am also thinking about returning my TV. Although I love the screen other than that I feel cheated and I really like 120hz because motion blur is quite irritating.

Are their any 55lm4600 that have trumotion installed on them?
What lg led tv's have true 120hz ?

I'm sure that the Lm4600 does not have Trumotion implemented. Models that do have it include the LM7600, 8600, and 9600 series Tvs. I'm not 100% sure about the LM7200, but I think it might.

Active 3D yes, but not for Passive 3D. 60Hz is fine because the image is painted in halves first 540 lines vertical for one eye then 540 lines vertical the other and your eyes/brain stitch them together. (It helps me to think about Progressive vs Interlaced monitors). ANYONE JUMPING TO PAGE 8 AND NOT READING THROUGH THE THREAD OR EVEN IF YOU DID READ THE THREAD IF YOU MISSED THE POST FROM RAAGAMUFFIN ---> READ THE LINK TO THE HDGURU ANALYSIS. IT'S CLEAR BY ALL THESE QUESTIONS 6 MONTHS LATER THAT PEOPLE HAVEN'T READ THAT YET!! - http://hdguru.com/lg-55lm6700-hdtv-review-when-120-hz-isnt-120-hz-updated/8281/
Quick Summary:
-The LG ##LM6700 & below panels are 60HZ - PERIOD!
-LG put Tru-motion 120Hz on the box & on the U.S. Website but it was a LIE!
-WHY DOES the LM6700 (NOW) Have a TRU-MOTION SETTING THEN? READ THE ARTICLE. In response to HDGURU calling them out about falsely claiming 120HZ with LG added a FAUX (FAKE) Tru-motiton setting - that's why it's not on the models below it because HDGURU and other sites didn't call them out on those models specifically!
-What does LG say to this? Instead of 120Hz which the panel can't possibly do (because it has no ME/MC chip which processes the extra frame conversion, they say they have something equivalent to the advertised & claimed Tru-Motion 120HZ, they call it: "backlight scanning" - and while this technique (performed correctly can lesson motion blur - [not like 120Hz however] - but that's besides the point because these LG TVs are NOT PHYSICALLY CAPABLE of performing it correctly) SEE THE VIDEO in the Link raagamuffin posted.

So no need to ask about TRU-Motion settings or when a Blur setting is coming because it's ALL FAKE!
Dear Brecklinton, with the luxury of the future I was quite P.O. with your first few pages of posts. HOWEVER, when I got to this one I couldn't help but feel your pain! It's a damn shame what LG did in the first place, but the bigger sin was them lying to customers as they did for so long. Customers that had a chance to return a TV but opted for trusting what LG reps had told them. To me I don't think I could handle it appropriately after all this time unless they gave me a sweetheart deal into a higher end model that had the features I was told this one did.

It seemed like you very much were liking your TV up until you found out they had lied to you. It's hard to ever look at the TV the same way again. But maybe if you are happy with the picture quality & 3D you will be able to move on. Just wanted to say I have a great deal of empathy for you in this case, not that it matters to you but thought I would say it anyway.

The problem is that these models & below DO NOT have the ME/MC processor used to do this. So what they did (besides plaster a feature it didn't & can't possibly have Tru-Motion 120Hz on the side of the box) they tried to come up with a slightly cheaper alternative done in software that shuts off the backlight (after frames) but the problem is that because of the LED array layout of these TVs (fine for most things but lower end) they can't do a complete top to bottom black frame so they do it in parts which negates the benefits a true black frame insertion might have had.

2013 MODELS will be out in a few months ---> Beware of which ones may have false claims. --- ONE additional this is not the only TV company this year that started doing the B.S.
http://hdguru.com/beware-of-phony-lcd-hdtv-refresh-rates/7726/
Raagamuffin & I answered this above but right there in that post LG is lying to you. "The 120Hz aspect of the TV..." can't be changed because it's only 60Hz & what they did do the botched black frame insertion is what is enabled at the factory & cannot be turned off!

That's incorrect. That was what people jumped to a conclusion early on. But it has nothing to do with WHEN the TVs were made. It has to do with the LINE and whether that line contained the necessary hardware to actually turn on & implement the advertised 120HZ. In response to HDGURU calling LG out on their deception & trickery on the 6700 LG put out a firmware update that APPEARED to enable "Tru-Motion" at long last. It did not as the TVs lack the hardware to actually accomplish this.
That shows LG willfully not only knew of the problem but attempted to cover it up and quiet up people that had bought these TVs.

That's false.
The TV isn't so much broken as something was advertised at there & functioning that isn't & can't be fixed with firmware (although LG sure tried to fool people that it could be).
Right!

I corrected you about this on the last thread you posted this on. It's a white wash cover up of lies. Negativity not directed @ U, but LG! I hope the old adage' is true in this case that it's not the lie, that it is their poor attempts to lie & cover up their lies that is the real problem. They could have handled this about 20 better ways. UN-

-The 2011 LCD LED panels were Passive not active 3D just like this years. The only panels that were active were the Plasmas.
-Reason it Looks different (not like Tru-motion 120Hz) is because it's attempting to add a black frame, improperly done, to the 60Hz panel after images but this can in no way create 120Hz or function or look the way properly done 120Hz can handle frame rates. This forces the 3:2 pulldown & interpolated judder problems that all 60Hz panels experience.
In 3D TVs You'd be safe getting a 7600. Not sure about the 7### below that would make sense they are grouped in tiers.
If you don't want 3D then there are models with much lower numbers there is at least one posted in this thread.
IF you or anyone else comes across a nice list of 2012-2013 models that do actually have True --> Tru-Motion 120Hz that would be really helpful to link or copy (giving credit) to who ever made it. Seeing as the 2012 TV season will soon be coming to a close that would be really helpful in ferreting out the true deals.

8 pages of complaints about the LG 3D TV with Tru Motion missing or unavailable as advertised. Time to start a class action Lawsuit! I believe the "Bait and Switch" complaint is legal in all 50 states!

Bought one of these for my sister. Feel kinda cheated, too. I would have spent more if it meant a real 120Hz panel. How do we press a more formal complaint with LG? It seems like they definitely should compensate people. I bought clearly thinking this was a model capable of 120Hz refresh.

I have to wonder if LG woudl bother to defend a small claims court filing? I would think for less than about $500 it just wouldn't be worth their time...

The problem comes from proving this kind of thing. For those of us who keep up with and understand technology it's pretty obvious, but for a juge somewhere I could easily see them being bamboozled and believing the whole strobing backlight thing....

Yeah how do we start a class action? Just got my 55LM4600 and am unhappy with picture quality. I first got their 47" LED Cinema 3D TV but then found out it was only 60hz and looked like crap. So I then decided to pay a little more to get the 55" with 120hz and looks exactly the same. Also can't take it back as I purchased off of EBay new with no return. LG is on my bad list right now for the false advertisement!

The only problem with a class action is it takes years to come through and then the lawyers involved get a few million and we all get a coupon for $12 off our new purchase of an LG Blu Ray player of $99 MSRP or more or something stupid like that.

That's not always how it works. My dad got a $66 check for a ~$400 computer and yes it sometimes does take years but sometimes they settle early and you get your $100 or whatever before thousands of people hear about it.

Besides the big win here would be to save future buyers from LG's lies.

thanks for the info DA1745.

this is getting pretty dumb with what they are doing. not just the refresh scams but also the contrast ratio. unless some 3rd party verifies things you cant trust anything.

and you'd think with companies competing one of them would stand up and say this is real info, compared to....verified by.... I dont mind paying more for the true product, but getting ripped off.

I recently bought a LG 50LS4000 LED (50") and it does have the option of setting the Trumotion level.

It even has a (user) option where you can dial up/down the level manually.

I found this set at Best Buy for $649.

Bought the 55lm4600 this weekend. I would not really care if it is truly a 120hz or 60hz panel as long as they offered a menu setting for us to adjust whatever software magic they claim to use. As long as it would appear to do what a true 120hz panel does I do not think we would feel lied to or ripped off. I would just be happy with an option to turn on the SOE at this point.

I cannot believe a major company like LG would pull something like this on it's customers. I would expect some no name knockoff company to maybe pull this bull but not LG.

It is really unfortunate that LG does not care about their customers and continues to market the TV as 120hz tru-motion and continues to lie about it being on a low setting. To bad we can't get someone more powerful on our end to take this up with LG. They do not really care what us little guys have to say......

In addition I first bought a 47lm4600 last week that is going back because of a defect but that came with software version 03.40.09 which is not even listed on LG's site yet. This version did not offer any tru-motion settings either so if LG decides to post it don't get to excited.

I just read through the whole thread. We have 55LM4600 from Sears' deal last month (came out to $230, or $180 if I count what I made selling the second one). I finally had a chance to hang it up on the wall and connect to HTPC.

It seems that TruMotion is not enabled via VGA, but enabled via HDMI. Has anyone been able to verify that via interumented test, other than my amateur eye?

I think the lm4600 owners have come to the conclusion there is no tru-motion on these TVs. You are probably just seeing a better picture with the HDMI cable.

I just got a 47LM4600 a few days ago and luckily I've found ways to circumvent the lack of built-in features by just running everything through my PC with Tridef 3D installed (awesome program). That really sucks about the false 120hz claims, but it's not like I've ever known anything different than this so I guess I'm okay with it if it can't be resolved. Otherwise this TV is way too awesome for me to want to return it. Curses upon whoever greenlit this advertising ploy at LG, though. What a steaming heap of BS.

What was that deal? That's about the slickest deal I have ever heard of...
