I picked up one of these displays on the cheap over the holiday and was curious about what everyone else is finding on these TVs.
First, the LM4600 and LM4700 are the same display, the 4700 line includes the soundbar. Since this is a display forum I decided these two lines should be consolidated since they are both the same display units.
I had a horrible time getting one delivered. The first one came with a display defect which I discussed here
. It took 3 more attempts before getting one that wasn't destroyed in shipping. I wish there was another option that didn't involve shipping.
I had been looking at the 6700 and 4600 models before deciding I couldn't stand the silver frame. One other interesting thing I noticed about the two models is that the 4600 has more inputs than the 6700. I could live without the "smart" TV and 240Hz refresh so the 4600 looked like a good entry 3D display for the family room.
The glare on the screen is pretty strong, and something to pay attention to if you're thinking about one of these sets. This is as bad as some of the samsung plasmas which I always thought had the worst glare.
The firmware which comes on the TV is lacking a few of the features and includes some support for things NOT included in this set. Some of the lacking features are the TruMotion. I'm not sure if it's enabled or disabled, there are no menu items to indicate anything about TruMotion. LG says they are aware of this, and there will be support in a future firmware relase.
Another interesting twist on the set has to do with 3D. Before 3D is active you're allow to bring up a 3D menu which is very cryptic and not easy to understand. There are 4 choices 2D->3D, top-bottom, side-by-side, and sequental frame modes. It doesn't appear to matter which you select, the set will do what it wants. It often defaults to the sequental frame, which is active 3D and this set only supports passive 3D. (A firmware update will dim out the sequental option, but it's still displayed). Getting the 3D to work well can be difficult. I have had the most difficult time with Disney 3D movies. The "cross talk" appears unless I can get my Sony player and TV to work correctly. I've also tried a LG 3D Blu player just to make sure it's the TV and not the blu player, the results were similar, but the LG blu did integrate with the TV a bit better. Another 3D option promised in the marketing material is "3d-depth" adjustment, this feature is not currently supported. The 3d-viewing angle is supported, but only seems to shift the ghosted image from left to righ, never eliminating it.
I haven't done a full calibration on it yet, I have done the built-in easy (or perfect) picture which I was quite impressed with. It was pretty easy to follow and did a good job getting the display configured. I'll be doing a full calibration when I get a chance.
I did look at some of the "service menu" stuff. The access code is 0413 if you choose to check these out. This includes test images to check for bad pixels which I found most sets have at least one, but I didn't have any which were noticable at normal viewing distance.
A note on the 3D glasses, they aren't the "good ones" show in the marketing material. These are flimsy glasses which are easy to bend and flex. I picked up a set of the solid passive glasses which I like better.
Some other random findings:
I did open up one of these to check out the interior and it's pretty simple.There is a large power supply board, an I/O board and one other board which I'm not clear of it's function yet. The I/O board has a spot for a second USB jack, I didn't bother to solder one on and see if it works, but I wouldn't be surprised if there's a second USB port on the back (of course you can likely just hook up a hub for the same functionality).
One other note about using a USB drive, it seems that you should "unmount" the drive when done before powering down. There appear to be some reports of damaging the drives if the drive isn't unmounted. This can easily be done with the quick menu, select the USB drive and unmount it.
