I decided to buy the 55ln5600 instead of the 55ln5700 because the only difference I could find was the 60hz vs 120hz spec.
Before I pulled the trigger on the 5600 I did a lot of research.The service manual covers a lot of models.Included is the LN5600/5700/5710/5750/5790 and it also covers the LA6200/6205/6650/6900/6950/6970 with all screen sizes 32-60".
Most models use the same Main board with nothing more then firmware differences.Since the 55ln5600 and the 55ln5700 use the same screen part # it seemed to me that if I decided to add the TruMotion feature all I would need is the main board from a 55ln5700.I have read that LG removed the the ability to change the tool options in the service menu or that would be another way to add the fake 120hz feature.
Well,I get the 5600 and low and behold the TruMotion setting is in the menu.
However.It only has an adjustment for dejudder.There is no deblur adjustment.
Im glad I didnt spend the extra $400 for this feature or the trouble of changing the board.The SOE is very noticeable unless it is set to 1 out of 10.
I watched most of the winter Olympics on this TV without TruMotion and I could not see much blurring.It was there though.
Overall this is a great TV for the price.
Is there really any difference between the 5600 and 5700?
It seems that the 5710 and 5790 models are the same as the 5700 except there is no internal Wi Fi board so it is disabled in the menu and one of the USB inputs must be used.The 5790 comes with a sound bar.
This is similar to the models that include the Smart remote.If its an option you have to use another USB input for the receiver.
