LG claim than their 3D is "Full HD 1080p" , that its a "1080p" when its being reconstructed in the brain. Trickery..  nod.gif

Technically its still 540p.

Technically there is no such thing as 1080p + 1080p, that would be a 2160p display. Which of the sets are you referring to that has a 2160p?

If you sit close enough to the screen you know what i meant.

Anything that utilize row-interleave or field sequential have to half the resolution, its using a low pass filter, all high frequency sharpness been cut off,  but they fix it with a trick by boosting the sharpness level at output.
A true 120hz will need frame sequential technique used by active technology (have flickers) , however if you think this is true , please provide some insights how the polarizer works at 120hz, instead of static fields.

Imho, the LM series is good enough for me. I'm willing to sacrifice the full HD for its 3D friendly and cheap glasses. Anyway, this 540p is referring to half-sbs movies right? If you're playing from 3D bluray, you'll still get 1080p - right? or from full-sbs movies ?

NO, i meant its has a 540p+540p NATIVE 3D dislplay. It displays 2 frames (L+R)  one shot, whereas active uses alternating frames to display 2 frames (L+R).

YES, even the Blu-ray 3D 1.4a HDMI frame-packing format is displayed in 540p+540p.

The sad thing is details been cut in half using low pass filter.

For a full HD 1080p utilizing row-interleave polarized 3D they'll need the 2160p display (projector resolution).

Obviously PASSIVE wins over ACTIVE 3D !

During my survey, I've compated SHARP and LG.... lastly, i go for LG, coz' the give 8 glasses, and it runs without battery..... SHARP 3D Glasses is heavy, difficult to fits to my glass.....

Enjoy !

You got me wrong, Im not saying passive wasn't good. I owned an LW5700.

But my stand is its still a 540p+540p, technically its not a true 1080p.

Its only "1080p" if you see with BOTH EYES, the 1080p is a brain interpolated stereo re-construct. Your brain combines the left and right image into one

Try read the small text (6-10 pixels) with only 1 eye.


Added on December 21, 2012, 6:22 pmAnother thing to consider before getting a passive is the viewing distance, you need to be at least 5 feet or more, anything less the 3D breaks. In active 3D you can even watch at 1.5 feet from the screen.

Other than that passive 3d is great, been using my LG 90% for 3D,

However sometimes I'll rewatch using my panasonic plasma active 3d 1080p in case i missed some details in the background, and sit closer like 2 feet from the screen.

I guess these are the little things that you have to cope up with. For me, unless they make active glasses cheaper and comfortable, I'll happily stick with passive. All I know is that I'll be watching my LM with 2 eyes open and sitting 6 feet away. smile.gif Happy to be discussing with you Mea Culpa.

For me buying 5 or more active glasess doesnt make sense, it cost too much. They are a lot heavier, and bad for ppl who wear glasses.

Active 3d is more like a "lone ranger" type like a PC monitor, more suitable for small room.

For family use and big crowd nothing beats passive 3d.

Actually before I bought the LM7600, I was sure I was going to buy panny 50st50k and was ready to buy 6 active glasses! Luckily I happen to come across this site and did some research. Also, the people on this site gave good advice on the price, instead of me looking solely on advertised prices. Thank you all.

I thought the LM6700 is 120Hz but hdguru website said that it's not and that LG's claim that LM6700 is TruMotion 120Mhz is untrue?
Hi, which model of the LM7600 did you get? I am planning to get one next week to enjoy 3D movie at home during my year end break.
*
My LM7600 is the 55" version. For 2D and 3D, I turned off Trumotion as I don't like its look. Not natural. I'm sure if you read this forum and outside, most will have this feature turned off. I brought my own movie samples to the shop to try the model out. I suggest if you are able - do this. All of these terms like trumotion, mci, 120/240 Hz etc are just technical terms (at least to me). Your eyes will eventually have to tell whether you are happy with what you're seeing or not. Good luck.

Hi Raif and other LM owners,
I am deciding between 55LM6700 and 55LM7600 and the only difference between these 2 models apart from the price is LM6700 is using MCI 400 (120hz) vs LM7600 MCI800 (240hz). But the HDGuru article said that the LG panel is only 60hz and many owners recommended to turn off the TrueMotion. So, given this, is it worth paying the extra $$$ for the LM7600 or just go for the cheaper LM6700?

Your comments and advice will be much appreciated.

Thanks.

Hi chowkh. The only reason I can think of, when I bought the 7600 as oppose to 6700 is because it is the higher model tongue.gif However, you never know if future fw upgrades make the trumotion better, in this case since 7600 has 240Hz, it would be better than 6700(120Hz). Only you can decide.

Hi I just bought my 55LM7600 from Desa Home yesterday. I got it for RM6300 with 3D camcorder and 12 passive 3D glasses. The box come with dual play glasses as well. This Christmas present made my hubby very happy. He's fixing up PS3 and HDD to the TV. We are still not very clear about downloaded 3D movie, something to do with file format so perhaps someone here can advice.

A 3D movie in a external HDD, mkv format. Connect via USB to the TV, can watch? It's USB, not HDMI. USB transfer audio and sound? I'm a bit lost here.
It's very cheap indeed, worth the price! smile.gif
Depends on where you buy from. Normally you take to the service center directly. However, I bought from Desa Home, LG 55LM7600, 2 years warranty. They said we can call them and they will follow up with LG for us for on-site repairs and such. It's not easy to transport a 55" so getting on-site support is better.
LG 55" LM7600 for RM6300 with 3D camcorder and 12 passive 3D glasses.
Hi chowkh,
The 55LM6700 is <RM5k. The 55LM7600 is 6.3k. The difference is the refresh rate. I think for LED there's only 2 types at 120 and 240. And according to HDGuru, the LM6700 is not true 6700. All this does not really bother me because I dont think our eyes can tell the difference but I simply chose the LM7600 because flatpanelshd.com reviewed it and said it's one of the better panels and best bang for buck if compared to LM8600 or LM9600 which we cannot afford anyway. You're spending in the range of 5k+/-, why save that bit of money and regret later? Just go for the best you can afford.

Congrats merchant9. For playing movies, I rely on media player rather than the tv usb player but it's your choice. I know a mr X will suggest using a bluray player biggrin.gif

You need a media player latest ver. that capable play 3d. But some 3D format still cannot playable. So you got to becarefull when buy a media player. Makesure it can paly all the format.

I try to play the 3D file from the ext HDD direct to my tv via USB. It can play the file. But audio format not support.
*
Yes, that was mainly the issue, the audio and sometimes some video formats will not be supported too. Well, if you're serious about buying a media player and a 3D one, I would suggest acryan HD 3D which is around RM5++. This player can play 2D as well as 3D. On the audio side, sometimes you can downmix it (audio processed by acryan) or passthrough - audio passed to receiver. If you're a movie enthusiast, just invest in a good receiver/speakers and get surround sound to boot.

Actually, I'm trying to get mede8er 10003dx locally but no luck. If anyone here has any news on this player, I'll be happy to hear from you.

Thanks! The TV is great and we both love it but drawback is our baby is sleeping in the room and we cannot turn on the volume at night. Sometimes have to watch the TV with very low volume. I am thinking of a media player too. Desa Home recommended me one with the latest Realtek technology for RM480 but I held back, didnt buy yet. Still surveying. What you using?

I was also told that HDMI cable v1.4 only support 3D and anything before that does not. I read somewhere that HDMI is the same regardless expensive or cheap but not sure if that's true.

Currently, we are trying to furnish our room, finding a suitable wardrobe + tv cabinet but there's nothing that supports up to 55". Just got back from IKEA and max out is only 42".
Yeah, I'm still looking for some, will get my brother (IT guy at home) to read some review. Any recommendations are welcomed. Thank you.
*
Since you mentioned IKEA. I just got this TV table and I use this for my 55LM7600. Got it at IKEA Bandar Utama (near IKANO)

http://www.ikea.com/us/en/catalog/products...5340/#/20105341

Even though its specification mentioned tv up to 50" , looks like it's strong enough. Maybe the tv is thin.
I would like to know the brand of the realtek player Desa Home recommended to you. Perhaps a name and phone number of the seller would be helpful. Thanks.

On the HDMI v1.4 issue, I believe that only v1.4 will send the proper 3d (frame-packed) signals to the tv and the tv will automatically change to 3d mode but if you still use the old v1.3, you will still be able to play 3d on the LM but you need to press the 3d button. To me, I don't mind. Anybody care to add or comment on this, as this is what I understand at the moment.

Yeah, I noticed too that yours is 6200 while the setting is for 7600/6700. Hopefully some of the settings are 1-1. You could try and see how they match up. Perhaps that site has one for 6200? Anyway enjoy.

I had LG47LM7600 and it is awesome but one drawback to me the WIFI doesnt work and the stupid technician try to cheat me that it is due to my wifi modem.

Hey comon, it dont even detect the AP and it the end, they said this is new model and they DO NOT have the wifi dongle to replace for me and ask me to wait. I am hopefully to upgrade to 55" later since it is under warranty if they cant fix it will top up some money to them. Anyone having issue with the wifi for this TV?
*
So far none from me. During installation, connecting to Unifi wifi modem is one of the task the installer set up for the tv. My unifi modem was detected and after they left, I proceeded to update the fw online.

Exactly! You can dig my old post.

The LM6700 has  a native 60hz LCD, 120hz is archived via  black frame insertion or LED scanning.

HDGURU has proven this where a 120hz with TruMotion MC/ME (Motion compensation/ motion Estimation)  MUST produce at least 600 lines of motion resolution. In the case of LM6700 with TruMotion on, its still doing the lowly 320 lines, which is a typical 60hz LCD characteristic.

http://hdguru.com/lg-55lm6700-hdtv-review-...z-updated/8281/

Why go for 120hz ?  120hz LCD (240hz LED specification) gives you even division of 24hz, to produce proper pulldown of 5:5 for pure 24hz performance.

LM6700 is 60Hz, thus succumb to 3:2 pull down which produce JUDDER! To overcome this it must engaged Trumotion, unfortunately its not 24p BUT 60p (Soap opera effect - many people hates it) . It defeats the purpose of 24p Blu-Ray.

LM7600 is GREAT with or WITHOUT TruMotion.

On the lm7600, my eyes prefer without trumotion but that's just me tongue.gif

guys,

I need user experience with the 55" LM7600 pls. A lotta review quote the negatives being not very good black levels and bad edge light bleeding. These 2 seems to be very consistent and comes up most review.

How is real world experience ? I'm not really keen on 3d just 80% astro and 20% bluray/dvds/mkv/avis.

Thanks
*
I own that particular model. Anyway I bought this unit solely for its 3d though I admit after bought it, I don't really really see 3d as much as I expect to tongue.gif Anyway the bad edge light bleeding is quite noticeable but I'm used to it by now. Nothing major though...only when light is dark and the screen is black. To me, it's nothing, really!!

PQ is nice, astro OK (wish all channels are HD). HD material imho is superb. If you do get this unit, you've got to calibrate it to get the black levels and PQ that is optimal to you. There're few suggestions calibration presets from this thread. In conclusion, I'm so far satisfied with this unit and I believe it's a good buy, but then again it's just me. Good luck with your decision icon_rolleyes.gif

hi raif,

thanks for you input. May I ask if you have noticed severe motion blur or it it pretty good at handling it ? Especially during football and fast action . Also how do you find the black levels ? Do they appear washed out  ? I really like this unit, for the design etc but leaning towards Sharp 840X due to black levels and motion .

appreciate ur input.
*
As you know, the unit comes with trumotion but I don't like this feature and I turn this off. If you look at the suggested presets, you'll find that most too will suggest this feature be turned off. Without trumotion, I don't think there is any severe motion blur (at least I didn't notice it). I watch a lot of sports on astro and all motion have been fine. Again, black levels are fine with the presets that I use.

The video is from 2011. The model LG used was LW series. The video has much of the discussion I've read about the downside of passive 3d compared with active, so content wise, nothing new.

However, for me, the buying decision had came down to the glasses used. I have a big family and if friends and family come over, then active technology is a no-no (active glasses are expensive!!). Imho, I think the LM series offers a relatively good 3d viewing experience as long as :

1) you don't view higher than the tv (the vertical mentioned in the video)
2) You sit relatively straight looking at the tv or at most within 30 degrees viewing angle
3) sit 4 feet or more from the set

Mea Culpa, my 1st hdtv is a plasma (panny). Still using it. I decided to get a 3D tv and my 1st choice was a panny plasma but too bad, panny plasma doesn't carry passive 3D technology, otherwise I would have already bought it.

Like I said, from plasma to LED, the PQ looks almost the same (actually the LED is a tad brighter and colourful) but I sure do miss my plasma wide view angle viewing, well - almost. tongue.gif
