They are almost the same price in amazon... but what do you think should i get? the old 55lw5600 or the new 47lm6700???
I cant find nowhere the real differences between the 2 models..
Could you help me here please...
I had some time to compare the previous model with the new model as I had purchased both the new 47LM6700 model and the previous 47LW6500 model for $999 from different stores. Wasn't sure which one I was going to keep until I played around with them in my family room. Here is what I found out about the primary differences. I did not compare the wireless functunality of the TVs.
It is obvious that LG's engineers have improved the performance of two issues that were problematic with the older model, audio performance and input lag. The sound on the 6500 (same as 5600) was tinny and colored. The sound on the 6700 was more natural and balanced with more of a low end than what was capable on last year's model. This was accomplished by adding a larger encasement around the two rear speakers. If you are using your TV's audio, this may be a consideration in choosing between the two models. Although I have a nice surround system I usually only use it for movies, not when watching other programing. As an additional bonus, it appears that from other posts that LG has now included the ability to pass Dolby encoding through the audio output. The older models downcoded this into simple two channel stereo.
While I am not a gamer, my two kids are and that was also a consideration in which model to keep. I had my older son play some of his XBox 360 combat games which require quick responses and a TV with minimal input lag. It was quite obvious that the 6500/5600 model had issues with this even when in game mode and after disabling all video porcessing. The newer 6700 model showed no noticeable input lag when in game mode.
Even though the newer model has made improvements in the TV's audio and input lag the older model still had some advantages which may make it more appealing to some. For some reason the 6700 model does not allow the user to turn off or adjust Tru Motion while those capabilities were available on the 5600/6500 models. If you want this capability you will have to step up to the 7600 models. The funny thing is that I really did not notice the soap opera effect on the 6700. Additionally, sports action showed no motion blur or artifacts. Not sure what LG made the internal settings for Tru Motion on the 6700 with respect to Judder and Blur but they seem to have found a nice compromise for sports and movies. When I played with the 6500 models Tru Motion settings I noticed that when stepping up the Tru Motion to "high" I did notice the soap opera effect on movies. If you want the ability to fiddle with the Tru Motion settings then you will have to either buy the older 5600/6500 models or step up to the 7600. For me it was initially a big concern, but after watching various programming I found no real complaints on the 6700 model.
As has been stated by many others, the new models use a more reflective screen. While not as glossy as other manufacturers it does reflect more light than the matte screem employed on the older models. Ambient room light is not an issue but if your setup in your house has windows behind your viewing position or other source reflections then you may want to consider the matte screen. If most of your viewing comes in the evening or if you are able to cover the windows during the day when watching TV then this shouldn't be much a concern.
Both models have the same performance with respect to horizontal off-axis viewing, which is well below average for an LED TV. In an earlier post I had stated that the new model showed much better off axis image. After seeing both TVs in the same setting I can honestly say that they are equally bad. There is a noticeable dropoff in contrast and brightness when vewing from an angle greater than 30% off center, maybe even at 20%.
As for the so-called improvements in the 2D-3D conversion on the newer models, I can honestly say that I saw no difference at all. I would not suggest using the TVs for this capability as they end up providing some strange distorted images that could cause some nausea. On the other hand, the 3D image on both sets when watching actual 3D content was equally outstanding for both models.
Overall the pictures on both sets were equally appealing. The image that these LG sets produce are excellent. On axis or slight off axis images are in my opinion better than any other set in this price range.
In sumary....
6700 Pros
1. Much better natural sound from the TV
2. Significant improvement in input lag
3. Ability to pass Dolby encoding thru audio output
6700 Cons
1. More screen reflections than the matte screens used in older models
2. No ability to disabale or adjust Tru Motion settings
