Once I familiarized myself with the various settings and how to use them, I did an Accurate Picture Adjustment with the AVS HD709 disk and was amazed at how close the "borrowed" settings were. A few more tweaks and tests with the AVS HD709 disk and the pq was wonderful. Confirmed it with a couple of reference DVDs (Blu-ray) and I was set. I've gone back after almost a year and checked again with the AVS disk and didn't need to make any changes. Bottom line, adjust your tv yourself with a calibration disk and/or meter for optimal pq. Using another's settings might work (and that's a big "might"), and is an excellent way to learn how to use the various settings, but ultimately you're best off to DIY.

Lots of reading here also helped me learn the basics, alot of you guys know your stuff and Im sure alot of others are as appreciative as I am! My best settings so far came from using the AVS HD709 disk for sure, and again it really was not hard at all to learn the basics and provided a nice return in the end with just a few minor adjustments. As you also said this tv is pretty darn close right out of the box.

obviously you won't be able to output actual tv channels through your stereo this way, and if your device has no analog outs either then you're screwed. it'd make things so much simpler if they just put an analog out on the tv...

Yeah, that's an idea I'll keep in mind. For the moment running audio out of the TV through the headphone port works pretty well. I haven't heard really any difference compared to running audio out of the RCA outs of the old TV. Only negative so far is a tiny bit of hiss from the speakers when I'm switched to TV and no audio is outputting.

I did more troubleshooting with my HDMI ports in the back of the TV that were giving me "no signal". I hooked up my PC to both inputs and the display came right up. So for some reason, HDMI 1 & 2 both refuse to work with my up-converting DVD player, only HDMI 3 will establish a connection. I find this puzzling because I assume all three HDMI inputs should work the same.

Is there any difference between HDMI inputs 1 & 2 versus input 3?

I have the dreaded dirty screen effect on my 55LK520. I was just wondering what the general consensus is on this issue. Is this a model-wide problem? I've seen a few people post about it. The issue is easily observed in quick panning scenes on a light background, especially with hockey and football kickoffs. It looks like the screen is dirty...dark spots on screen that do not move with the image. The spots are fixed on certain sports throughout the tv while the panning is happening. I hope some owners can check and weigh in on their experiences. I will be returning this set, but not sure if I want to take the chance with this model again. Besides the DSE, it's a great tv!

I wouldn't I went through 2 42lk520's and 2 42lk450's that had that all ips panels all made in nov '11. I got a 37lk450 yesterday and it made a buzzing noise so bad you had to turn the tv up not to hear it. If the back light was at 100 it would quiet down plus could smell burnt electronics. Took back today and got my money back. Im going to get a Panasonic TC-L37U30 need something for gaming xbox. Just thought I would share my experience.

My 42LK520 has what I guess you would call "DSE," but it's more like banding, observable on solid colored backgrounds. I don't really understand what causes it, but honestly I seem to have this problem with all LCDs I get, so I just live with it. Could be worse.

...so good. I bought the 42LK450 at Costco a week ago and so far no problems with DSE or backlight bleeding. I have played around somewhat with contrast and brightness but other than lowering the backlight, the factory settings aren't too bad. I will try out the AVSHD disk when I get around to it.
It also has the IPS panel and was manufactured in Nov '11. The one thing I like about Costco, is the two year warranty and the extended is just $29 (for under $500 TV, mine was $498) to make it 5years total.

Yea or banding not sure what to call it. If watching a movie with light colored background like the sky you could see darker spots that didn't move. All 4 of the lk's had it. And they were all made in november all with ips panels. Don't know if lg had a bad batch of panels or what. Im done with lg.

Even Sharp Elite has it, even plasmas have it. So the correct phrase should be "I'm done with TVs".

looks like the new models are almost ready for sale. they look and are priced the same as the lk series, otherwise no real info:

i'm really hoping LG doesn't deviate from their usual low lag/great color accuracy, cause i'm not waiting for reviews before buying.

Are the black levels on the LK520 sets as bad as they were on the LE5400 models? Those were more of a gray than a black.

Mine was an August build and was the IPS panel, so that would be a really large batch

I've heard some people say that all LCDs have it and that would be disappointing if it were true. I wouldn't say mine is banding and it is mostly visible in one spot and is more of a large splotch. I could be wrong as this is my first HDTV. Makes me miss the uniformity of my CRT, but it was getting really hard to watch basketball/football games on the HD channels on the CRT in the 16:9 format...way too small on a 27"er!

My 47LD520 (S-IPS panel) doesn't have any banding or DSE at all after a year of use.

Hey guys,

I've had my 47lk450 for about 6 months now and I'm not sure if I noticed this earlier but when watching cowboys and aliens (yes I know...I know lol) via WDTV thru HDMI, I noticed global dimming in alot of the darker scenes. Is this normal?

Dynamic Scrooge Effect........ that's funny. I believe they mean Dirty Screen Effect. The way it was explained to me is that it's like looking thru a screen door at times. I've never seen it myself. My LG has a crystal clear picture.

Plasma panels also have Dirty Screen Effect. Not just LCD panels.

It is a form of uneven screen illumination. Sometimes appearing like a slight smeared-like haze in some areas of the screen almost like you wiped it with some cleaner and it left an uneven haze behind.

OK ... that makes sense ... my acronym decoder (which is apparently powered by an original 8088 processor) finally kicked in about 5 minutes ago before I logged on.

I'm pretty sure my LK450 is "DSE" free, although there is a *very* slight unevenness to the backlight illumination that's only visible on a 100% "black" frame. My old CRT RPTV was significantly worse even after (or perhaps because of) lens-stripping.

Anyway, thanks for clearing the mental log-jam.

Wow . . lot's of history here. 8088 processor .. . a screaming 2MHz no doubt! My first Pc had one of those! Back in .. . . ? Well you don't need to know!

Ahh. . striping the 'ol RPTV . . . I had three of them from 1983 (RCA/Hitachi) to 2003, a "real" Hitachi Ultravison HDTV. Man .. . when LCD finally got good enough for me to look at in late 2006 ,early 2007 I couldn't wait to be done with red/blue shift and constant convergence. Even after striping!

Well, TVs still aren't perfect but way better now. Even a little 26" Sanyo we have in the bedroom is decent and actually has pretty even gray scale once tweaked a bit.

My 2010 42LD550 has a very nice panel in it. No DSE with just a bit of uneven back lighting with an IRE 50 or 60 screen up. . . you have to STARE at it and look really close. No flashlighting or other issues and beautiful color.

Moving on . . . ..

After reading 57 pages (yes, I admit reading every page, albeit, some posts I skimmed over) the general consensus seems to be that there is a problem with LG LCD panels. Of course, that isn't the case and we all know that most post to complain, very few post to say how much they like the product and feel that they made a wise purchase. Also, all TV manufacturers have "issues" as well, but I do like my 42LK450. The screen, at least to my eyes, is just fine.
I chose LG because my son bought a 47LB5DF back in Dec 2008 and we never had a lick of trouble with it(it also has an IPS panel). It's still going strong, but he moved it into his room a month ago for gaming, forcing me to buy a TV.
I picked an LG because I didn't want to re-program my RS 15-2116 remote.

Welcome to the LG gang!

Here is some info that may be of good use to you and help get a great picture on your new LK model.

You can use the following post to download and burn a *Free* calibration aid on a standard DVD-R, but playable on most Blu-ray players. This is fine way to get started in learning how and where to make your settings. This AVS HD709 disc also contains a video on what to look for when doing your TV settings.

Also, Post # 2 in the following thread has much in the way of valuable information to get a very good picture on your new TV!

Thanks, yup, read them all. I downloaded all 3 versions of AVSHD 709, but since I don't have a BD player, and until my DVD player blows up, have no real burning desire to get one, I use the MP4 version through my WDTV Live and set it up that way. At least set up the BtB and WtW settings. I don't have any color filters so I didn't go the rest of the way.
Like I previously posted, I really like the color and picture, and I don't notice any of the oft-mentioned screen "artifacts" that some see. I just hope I don't have to post any problems.

Good to hear the TV is looking good so far.

You know, you can use the Expert1 or Expert 2 picture modes and make some basic settings with your AVS 709 mp4 version. There are built in color filters in the Expert Control section of the Expert menus. Give it a try. You could also give the 2 Point Method a try for removing any tint in white balance.

This line of TV is a great bargain for the level of adjustablity.

Anyone else care to weigh in on if their LK520 has the dirty screen effect? You notice it on faster panning scenes(football kickoff, hockey, basketball,sky scenes) and it presents as a dark spot or blobs that does not move with the picture. I am planning to take this tv back, but I am wondering if I should take a chance with another 520. A couple have weighed in and I appreciate that, but I am looking for more input. Thanks.

The first tv I brought home had the DSE and light bleed issue. I returned it and my second one has neither issue.
