I wanted to start a new thread for the 2011 LG LK Series. I almost bought a 42LK520 today but I am concerned since it is so new and there is zero information/reviews out.


I'm also interested to see if there will be a panel lottery for these sets too.

Well, I used a version of the settings listed here (with a few changes - see underlined comments) on a 42/520 and it seems great. I watched it for a few hours on various HD programs (no Blu-ray) before I gave it to my mom. She loves it. I realize using someone else's settings aren't optimal but it got the TV into the ballpark for my eyes.


BTW, the TV in my theater room is a 65 inch CRT Mits that was professionally calibrated so I know the difference between a Calibration and an APA (see otto's post).


Here is what I ended up with:



HDMI Input Set for Cable Input


ISF Expert Baseline 1


Energy Saving Off for Day Time ( Minimum or Medium at night)


Range of Values based on user reports.


Backlight 41 (27-65) Higher setting causes wash out.

using medium is pretty much all you can do in that case

yes, colorimeters and spectrophotometers exist for a valid reason, not just for making profits


even though the factory calibration of these sets is pretty crude, very high end color analyzers are used to calibrate white balance within the service menu


thinking you can set the color of white by eye is wishful thinking at best; many would consider a professionally calibrated set too dull and yellow until their eyes adapted to the calibrated image

Does anyone have a LK450 hooked up through the miniDP port of an AMD HD 6000/7000 series video card? If so, are you experiencing any flickering/blinking issues when running an intensive 3d app? (e.g., 3dmark, furmark, direct3d games, opengl games, etc).


For me, right after I start a 3d application, the television goes black for 1-2 seconds, then an image pops up for 1 second, then goes black again for 1-2 seconds, image shows up for 1 second, and repeat. During this time, Windows is making the device-connected / device-disconnected background sound. If I'm lucky, I can alt-tab out back to the desktop. But sometimes my keyboard becomes unresponsive and I have to hard reset.


The above *only* happens if I'm using the videocard's miniDP port. When using the DVI port or HDMI port, everything works fine.


My current theory is the EDID exchange is causing handshaking/synchronizing issues, and/or faulty AMD drivers when using the miniDP port. I need to find an actual PC monitor to do some more troubleshooting. But until then, anyone have any ideas?

A perfectly valid (APA) alternative would be to only adjust the highlighted settings and leave the rest at factory defaults. This will give you the best image possible without a meter and calibration software.

It may depend on your signal source. If it's cable or OTA it might change, but you don't say. Plus, was it evident with the exact same program material program material and where was contrast set? There could be several reasons one being you were using a preset and the color temperatures for some of them are fairly bright. Which preset were you using and with what input source and material?


@PlasmaPZ80U

"


And it could very well be too dull and yellow. As you know very well, Micheal Chen, the source you often quote, found that the calibration tables for many TVs and the meters were unreliable. Charts and graphs do not tell all.

The poster said he was satisfied with what he obtained even comparing it to his professionally calibrated 65" Home Theater TV.


This type of conversation perhaps is best suited to the Display calibration sub forum. All you are doing is continuing an adversarial atmosphere here. Or is that your point? Why not give this a rest and just let people make up their minds on their own instead of this continued hard sell?



We get it. You don't agree.

Glad to hear you obtained satisfactory picture quality using settings obtained by your eye! It just goes to show that with some judicious application of how the controls work results in a beautiful picture for your mother.


This line of LG TVs have a very nice palette and really shine with just some modest adjustments. Nice to know that LG has supplied such a nice array of USER accessible controls in the Expert Picture Mode including the very useful 2-Point and 10-Point Method for manually setting white balance closer to an optimum point.

Are you the spokesperson for this thread? It seems to me you are equally guilty of what you accuse me of doing. You don't need to argue with everything I say and suggest, even if you believe the exact opposite of it. Let the other posters in the thread speak for themselves instead of trying to represent everyone else here. It takes two people to have an argument.

I don't think it depends on the source. For someone who used "Medium/Neutral" color temperature, even a perfectly calibrated to D65 TV would probably seem "yellow", at first. And maybe it is, because in RGB balance one color prevails.

After all, the standard is based on daylight "color temperature", and there's heavy sun's influence.


But just for the record, my sources are pretty much everything
: Blu-Rays, DVDs, PC, Game Consoles. Satellite, too.

Are all 47" versions of the LK520 TV using the S-IPS panel type? I had seen this rumor a few places and just wondering if anyone with the 47" version ever got an MVA panel.

I think the panel lottery applies to all screen sizes and models. The safest bet would be to check that the 4th character in the product code is a Y and not a D or J.

In the 2010 models LG had some 46" and 47" LCD panels but all 47" were LG made since it is one of the "standard" sizes of panel in the LG stable of panels. This year, if I recall correctly all the 47" owners reported S-IPS panels. You can use the Search Thread option at the top right for 47LK520 or LK450 and see.


However, as was last year, as the model year wore on, some TVs started to get panels from other sources. So a lot seems to depend on manufacture date. Soon the 2012 models will be debuting and it will be interesting to see the model line up. I hope they still continue with some CCFL models or at least get more refined with LED full array TVs.

If your color temperature seems too yellow, you can check it in the Expert menu by going to Method and select 2-Point. Then scroll down and see what the R,G,B Contrast setting screen looks like. If it looks yellow or some other tint, you can try correcting by reducing red and green in that setting and even add some more blue. You don't have to leave it that way and you can always put those settings back to their respective "0" points.


But it would give you an idea how a more neutral, but warm color temperature would look. My LG is the same way and I corrected it this way as did others.

It's pretty silly to expect every owner of a TV to go out and purchase a meter and invest the time to learn how to perform a full calibration. It's a fairly involved and complicated process.


There's also personal preference to consider. Many of my friends bring their TV's home, set it on one of the presets and just watch. To them, that becomes what a TV is supposed to look like. Plenty of people don't like the look of a calibrated picture. Fine by me. Why should I care?


Cost is another important consideration, as Phase700B keeps bringing up. In your case, you've spent what - $450 to be able to calibrate a $600 TV? And if you want to know it's right, you'll need to drop another grand or so for an i1Pro spectro - even then, how will you know you received a good, accurate unit? Sure, you'll be able to use these devices to calibrate any TV's you buy in the future, but after a few years of sitting around your devices will need to be calibrated... (BTW - you may be able to rent a i1Pro to profile your C6 - but then, who knows what kind of shape it will be in?
)


Given all this, I see no problem with a knowledgeable poster recommending that an owner tries to eyeball their white balance if they've got an issue with their picture and nothing else is working. If their picture ends up looking better to them, progress has been made - even if they end up making their white balance worse from a technical perspective.

What colorimeter do you use? I'm going to buy 1 but can't afford much. Is X-rite i1Display2 a good choice? My set is in warm mode is so terrible and yelowish, W25 seems to give best result (by eye) but I'm not so sure.


So what's the best starting point for me to start calibration? Warm mode or Medium ?

To get rid of yellow/green in the warm picture setting use one of the Expert modes instead of the Presets where the W50 - C50 can't remove it. Have you tried any of the Expert Picture modes with any settings and using the AVS HD709 disc?


Try the procedure in Post #1551 one page back from here. It worked for me. and others.


By the way, I owned both X-Rite Display 2 (D2) and Spyder 3 colorimeters and sold them. Here is a link you should read:

You make some good points. I am considering either getting a used spectro for cheap or getting a professional calibration done at a reduced rate. And I spent only $450 for my 42LK450 but at least as much for my CalMAN DIY/C6 combo.


Moving on to the average TV owner on this forum, I understand using test patterns and your eyes alone is enough for most people and if they do a basic calibration of the user controls meant to be set by eye with the aid of test patterns, that is a perfectly acceptable and reasonable decision.


However, copying settings and/or trying to set advanced picture settings like grayscale, gamma, and CMS controls by eye with test patterns alone is not only a waste of time but it also provides no guarantee of making the picture any closer to the reference standards. At best, the image is no better than when you started and at worst, it is much worse than when you started. These two approaches are simply ineffective and just plain pointless. This has been proven time and time again by calibrators, both DIY and professional. They are not viable alternatives to actual calibration, only using a setup disc to set the basic controls properly by eye is.


And this is the AV Science forum, so making white balance worse from a technical perspective is not something to encourage nor recommend to new TV owners/users of AVS. I don't think AVS needs any more posters contributing to the misinformation all too common on this side of the display forum.

I'd try getting the standard D3 colorimeter (about $300). A spectro would be ideal but I believe it would likely cost at least $500.


If you can't get either of those, I'd stick to setting the basic picture controls with a setup disc by eye. The cheaper meters like the D2 and Spyder 3 are not worth it. Use expert picture mode and preferably warm color temp. If warm looks way off to you, medium is the next best choice (though it will likely be farther off from the target D65 white point).

The only difference is of degree. To you and some others, only a calibrated "accurate" picture with use of a meter is acceptable and you do not accept that a decent and satisfying picture CAN be obtained without one and is fine for others.

Yes and no. What I'm saying is that without using a meter, you'll never be "sure" of your results and thus you will be constantly tweaking settings. One night, something will "look off" and you'll spend an entire evening "fixing" the problem, only to undo your "fix" the next night. (I may have a bit of experience with this
)


In other words, it's a waste of time that could be better spent enjoying actual programming.

Then apparently it's a waste of time also when using a meter. I just read a few recent posts in a "calibration" sub forum and another pro calibrator said the same things about those who have meters. They think they have it "right" and just know it's perfect, but then put on a movie, or watch a football game . . . and "something" just doesn't look "right". Or they read something about profiles being incorrect (many times they are) or another meter is "more" accurate and they have to look at it again. Or they bought a meter that supposedly is NIST certified only to find out that they now have to buy another meter to make sure the first one is "right".
Oh, and then the next "Best meter ever" comes along and all previous meters are cheap junk. Or they see another guys TV and it looks better so do a picture reset and start all over!



Human nature. If you say that doesn't happen just because you buy a meter you are selling snake oil.




The truth is most people can get picture quality that is absolutely great by using all the controls on their TV with a bit of knowledge. Most of us here in this thread and others are testament to that. And many of us are here to dispel

the misinformation that they have to buy an additional piece of equipment to get the best picture quality. There is always something to sell. And those who have purchased a meter (or 2,3) HAVE to defend the purchase they made lest they appear duped into a bad purchase. Agreed, though, if you want to make a hobby of using a meter that may be fine for some. But it certainly isn't necessary.

I just calibrated my settings after breaking the TV in for about a week- used the picture wizard. The wizard actually worked very well, IQ looks great and even better than other settings posted in this thread.


If you've tried other people's settings and still aren't happy, I'd suggest using the wizard since everyone's TV can be slightly different.

Yes, we are fortunate LG provided that handy little feature in the TV!



Settings also depend on the amount of room light you usually watch the TV in and, yes, each TV will be somewhat different. Even the settings you've obtained using Picture Wizard sometimes can use a little tweaking. If you get a Blu-ray disc with THX Optimizer on it you can check how the Picture Wizard settings worked out. Usually, pretty close.
