Official LG xxLK520 xxLK450 - Page 3

I think you'll be happy with an LG. This is my first LCD but I can't imagine a tv any better or with as many features for the price that I paid for my 47LD520. And once you correctly calibrate it.... my oh my

So I went off in search of my source for my IPS-Alpha statement, and it turns out that I stand corrected. What I meant was "AS-IPS" in the high end sets (according to my source: http://www.avforums.com/forums/lcd-l...l#post10716979 ) I got the terminology confused.

Thanks for questioning the mis-statement.

I just purchased a 32LK450 at Best Buy this last Saturday. They had it on sale for $50 off. I could have purchased online for less money, but I wanted to have an easy to return it if I don't like it.

I have it connected to my computer via the HDMI1 port. I just hooked it up and am tweaking it now. So far, I am really liking it (only two hours of use), so I will probably keep it.

Do you even know what moving picture resolution means? Because I didn't and assumed that just meant 60 hz, which is the same as the LK450. And my quick search seems to imply that too.

Don't discount Panasonic, especially considering they were the set to get for gaming prior to last year.

If I sound annoyed it is because I hate 1) people who comment on specs they don't understand 2) make unhelpful generalizations.

what product code did you get? CUSD or CUSY?

@djams - Thanks for your tips. Using the 10pt IRE, I've now gotten really accurate gamma, temperature, and luminance curves. However, I'm still struggling with the color gamut. I'm still getting red and green primaries that are outside the BT709 gamut. If I drop the red and green in CMS to match the reference, then my red and green luminance goes way down. Could you offer some suggestions to this? Could you explain the 75% technique?

Thanks.

You're very welcome.

Could you post (or PM would probably be better) your latest .chc file? I'd like to look at the color readings before giving advice. I'll try to look at it later tonight.

300 Moving Picture Resolution is VERY low according to this comparison chart. Please do yourself a favor and steer clear away from that horrible LCD!!!

Panasonic's great if you're buying plasma tv's. But when it comes to LCD's, LG, Samsung and Sony seem to be the best from all the reviews I've read AND the showroom tv's I've seen compare to the Panasonic's.

60hz ~= 300 motion picture resolution. Apparently, that makes the LK450 also "yikes" and a "horrible LCD!!! "

http://hdguru.com/how-to-pick-the-right-hdtv/2630/

"Standard LCDs incorporate a 60 Hz refresh rate. This produces motion resolution of around 320 lines (per picture height) out of a possible1080 lines. 120 Hz refresh ups the motion resolution to around 600 lines, while 240 Hz kicks it up to 900 lines or higher."

The problem I encountered with my 2010 LD series is that the CMS controls for primaries don't adjust 'right' when using 100% color windows. However, if a 75% saturation window is used, the color and tint adjustments behave as they should.

Here is a very good post that describes adjusting CMS using 75% saturations:
http://www.avsforum.com/avs-vb/showthread.php?t=1134710

Using this approach, I was able to make CMS adjustments that improved my primaries, where previously (using 100% color) my adjustments always made the deltaE's worse.

Be sure to grab the calibration aid spreadsheet that's linked in the thread - it's very handy.

From what I heard where I work, the LK530 series was a step up from the LK520 series, it added connectivity and the "Magic Remote." LG decided not to go forward with the series and only produced limited number of the LK530s.

I'll trust scientific measurements over random quotes. Thanks anyway Panasonic rep!

Yes that's what I thought , i was apparently the only one that had that model, so I decided to return it and I picked up the 47lv5500

UPDATE: Incorrect calibration file included. Do not use. I'll have new corrected on up soon.

djams,

I've been calibrating my 32LD450 using the above mentioned 75% saturation method. In HCFR, I'm actually using 8points for saturation rather than 4 points, and it seems that my saturation is pretty good up to 87%. Of course after that, it shoots up to quite high. At least 87% of my colors should stay fairly true to rec709. I'm attaching my HCFR file for you to check out.

Thanks again for all the help.

P.S. Out of curiousity, does your Eye-One Display2 work with Lacie's Blue Eye Pro software?

@emmat,

On your 47LV5500, is the Edge Enhancer forced to High for isf Expert menus in PC-input mode? Vice versa, is Edge Enhancer forced to High for non-PC input mode?

Anyone know how LK520/530 compares to Samsung's D630 PQ wise?

I'm planning on using the display for computing and gaming.

Oh cool, I'm now a Panasonic Rep.

Great, I didn't even say anything good about the set aside that they list it as being IPS-Alpha!

Don't bother checking my posts to see that I mainly hang out in the LD450/LK450 threads and has been the IPS version is the set I've been trying to get. No, that would be against your jump-to-conclusions style.

Let's see, 1) dismissing a set based on a spec you know nothing about 2) making huge generalizations based on brand names as if they were fact 3) resorting to blind accusations.

Earned a spot on my ignore list.

Hi all,

I'm currently a Panny Plasma owner, but due to a laundry list of problems I care not to get into, I'm considering a return for an LCD, namely the LG 55LK520.

Can anyone (preferably an owner) offer their opinion on this set?

That looks good on the charts - did it translate to an improved picture? I see the big improvement in your grayscale measurements as well - nice job!

I don't know about the Blue Eye Pro software (never heard of it).

@djams

I spent a lot of time getting this right. My Spyder2 meter is really slow unless I extended the read time. In terms of improvement, it's definitely less saturated than before. I just wished that LG had a more flat response to the CMS controls. Nonetheless, it is really good for the money.

Out of frustration with the Spyder2, I just ordered a X-Rite Display LT meter. I hope this will improve reliability, accuracy, and read time for future calibrations.

Any LK520 calibrated settings available so far? It would be greatly appreciated if someone could post theirs!

I've tried a few LD520's settings and it looked downright horrible.

This is good info to know (you may have tried some of my LD settings). I suspected that this might be the case. So far, I've come across calibration charts for two 2011 LG LCD's (kanedo's LK, and an LW in another thread) and both had primaries that measure well outside the REC-709 color gamut before adjustment. So it may be that LG has made significant changes in the 2011 models. Can't say for sure based on only 2 observations.

Can you elaborate a little on the pq shortcomings?

FWIW, djams settings on my LD520 just look awesome, so this is interesting information.

djams, I seem to be following you today

You can't use a LD's setting on a LK. I've calibrated both a LK and LD. The LD I had a stronger red push out of the box. A lot of adjustment had to be done on it to bring it to spec. Out of the box, the LK had a more even distribution of color. However, it's still far from perfect. Either way, my calibrated settings came out quite different for a LD and LK. I would not recommend using LD setting on LK.

If anyone is interested, I can post my revised 42LK450 calibrated settings on here.

@djams, I'm getting my new Display LT today. I'll compare it to my Spyder2 readings and post an updated chart.

kanedo,

I would really appreciate that you share your settings with us. I have a brand new 42LK450, and lacking professional calibration equipment, your settings will serve me as a starting point to calibrate mine.

I look forward to seeing the comparison, and also hearing what you think of the DisplayLT vs the Spyder

Thanks for the positive comment, Otto

Hi everyone,

I just received my new 47LK520 yesterday. This is meant to be the TV for my new appartment in which I'll be moving to this july. I was going to get the 42'' model, but decided to go bigger -> Great decision.

Of course, I couldn't keep it packed.

I didn't do the loupe test yet, but the product number is 47LK520-UA.ACCYLUR. So from what I understand, this could be an S-IPS panel.

I used the picture wizard the change a few settings for now. So far I'm impressed with the picture. Colors look a little washed off but I haven't played with it much yet. I'm sure the picture can be improved with the correct settings.

As for games, there's input lag with the playstation move, but that was to be expected.

This set will be used for everything: sports, video games and blu-ray movies, as well as infomercials (just kidding).

Perhaps I could give more detailed impressions once it is correctly calibrated, though I'm no expert. In the meantime, I will be browsing this thread and trying to soak up as much information as I can.

Okay, I just did a full calibration with the Eye-One Display LT. it came out much better than the one done by the Spyder2. Gamut was almost right on with the EODLT vs the inaccurately wide gamut my Spyder2 produced. I'm including my final calibration report using HCFR.

Since the EODLT can read much lower light than the Spyder2, I'm actually getting 700-800 contrast ratio. On top of that, the read time was much quicker. I was able to do the calibration in less than half the time it would take with a Spyder2.

My Spyder2 is officially retired.
