Neither the LG or the C6500 show any banding on the standard gray ramp test patterns that go all the way from 0 to 255 across the screen. That ramp covers too much range to expose the banding. In fact, that ramp is pretty much useless as a diagnostic pattern in my experience, at least for any modern display.

You need a more gradually changing gradient to expose the differences. You might find such a pattern in a movie, for example, if there is a uniform wall in the background with a dark subtle shift in luminance from right to left. Then the bands will be evident on the Samsung, and the big ugly dithers on the LG.

Do you have "Blade Runner" at Blu-ray-Disc or HD DVD at home?

I think, I knew, the transfer had banding besides the ugly DNR, but now I'm not so sure, that it isn' the LG-Plasmas fault.

I was able to get rid of the banding at Decker's door when Rachel visits him the first time, but I have still bandings in fires, lamps, skies and the dust in thy sky in the opening sequences, also the light/dust in Sebastian's house right after Decker kiled Daryl Hannah.


EDIT: And btw, I got banding with my first calibrationexperiences with the 20point-calibration in the 256 AVS709-greypattern, so it is "possible" to get banding even there.

The Blade Runner Blu-ray disc is one of the most impressive transfers I've seen. I have the full blu-ray collection. It doesn't have any banding on my Plasma that I've seen. If you have banding problems, more likely it is a setup issue or limitation with your equipment.

I mean the Final Cut, that is plagued with lots of DNR and a medicore bitrate of only 17Mbs.

I would be happy, if you could check dust, fires in the opening sequence and lighthalos in Deckards appartement and Leo's room for banding.

So there are two versions of Blade Runner on BR? 17Mbps does seem to be too low. Aren't they usually in the 25-35Mbps range?

There are even drops down to 12Mbps. Singlelayer-BD.


And the banding is indeed in the transfer-> http://www.dvdbeaver.com/film3/blu-r...blu-ray_1x.jpg

Minor update: took 2 points from LG 55LHX for the dirty screen effect issue.

Also updated the review index to include the latest 2011 reviews and the Swans loudspeaker review.

I only used 2D mode. The set was fresh out of the box. The owner is local, so we wanted to go back after a few months and see if there was a significant change from the break in process.

Really looking forward to this review Chad! Bring it out already

I too would love to hear your findings on the pz550 series...

All the documentation is available in U.S. english

This is the complete LG plasma Panel Alignment Book (quick reference), latest version (03/31/2011): http://136.166.4.200/contents/Displa...t_Handbook.pdf

LG U.S. got the explanations from the complete Training Manuals of many plasma models, and they have arranged that book. Read it carefully before start to do something. If you have never done such things before, it is better to have a look for an expert TV tech friend. The right way to arrange the tuning work, is to use a big mirror. Put the TV screen in front of the mirror and look at the mirror during tuning. Use only full plastic screwdrivers (easy available and very cheap) and remember that there could be high voltages on some circuits, so be careful. It is like to work on tube amps, you know? Only a bit more difficult because you are working on big screens, and that's the reason why you need to use a mirror (for safety reasons, at first).

For many plasma models, complete informations and training manuals (very useful) are also available. On this page there is the list: http://136.166.4.200/SubPages/Directview_PDP.htm

clic on the model you are interesting for, and on the left of the new page you will find the docs available for download. There is even the new 50PZ950 and PV450 models, as well as the PK950 and 750.

With such informations available, I think LG plasma are well worth a look. I'm going to buy a 60PK980 (same of 60PK950) during the next days. Now it has a very good price in my Country (1170 euro including shipping) and it is the right time to buy it. I'm not interesting in the actual 3D stuff.

Chad,

I don't see my 2010 PX950 model in any of the pdf documents from this link?

For the panels alignment, the boards of the PX950 should be the same of the PK950 model. The procedure is always the same and the voltages are present on the label of each individual plasma panel, as explained in the Panel Alignment Book. Take a look at the PK950 procedure, and you'll understand how it works.

The pages of that web site will be updated, as well as the docs.

BTW, I don't think this is the right thread to continue to speak about this things. But I don't know what thread could be the right one

Thanks for this info!

I don't see the LG 60PK550 listed, but I do see the 60PK750. Is that the closest match to the 550? Are there any significant differences?

The 50-60PK550 are listed in the LG plasma Panel Alignment Book (first link I gave you before).

Chad, maybe I'm doing something wrong, but the link to your overall table of all displays reviewed is missing from your signature (I can only link to your 3 most recent reviews).

I would be happy to, but I don't know very far in advance what I will have the opportunity to review.

Are there any updates in your rankings?
post #505 of 506
Please update your picture quality chart when you have time. I'm interested in seeing how the latest models you've reviewed stack up against the others. Thanks.

Thanks. I have another busy week on my calibration tour, then I have to meet with my friend/web guy to be trained on how to update my new webpage. Hopefully soon after that.
