Yeah, 90% of the speed of light is pretty pokey. Better find the shortest HDMI cable you can get your hands on!

Hmm. How does full 1080p of motion not suck? We're settling for less here?

Several of Panasonic's plasmas have specs that say 1,920 x 1080 motion resolution.

Or is that all marketing?

that's with interpolation, if you keep it honest it does 900 i think. aka the same as the LGs

Notice i never said that this would even work, it was just a suggestion. I had to order new cables anyway so i just got a shorter cable and thats all i stated. No need for the sarcasm.

I'm curious about this too. Does anyone have Spears/Munsil? One of LG's 2009 plasmas was measured by Cnet to be in the 800-900 lines range, i.e. on par w/ 2007 Kuro. 2008 Kuro measured about 5-10% better, not much of an improvement.

I still see some occasional motion blur on the 550. Sometimes this is "lost" in infrequent film judder (Blu-ray) or telecine stutter (CATV) -- all the same I wish the blur weren't there at all. Maybe a next-gen plasma feature?

Panasonic claims 1080 lines motion res but I don't know whether this is achieved without frame interpolation as on LCDs-- the cure worse than the disease!

We're setting for what's realistic

Panasonic quote 1080 lines of motion resolution. From what I've seen, it's closer to 900. I believe they can manage 1080 with the Intelligent Frame Creation (as it's called on the Euro models, maybe on the US ones too?) engaged, but that system, like the MCFI on LCD TVs, introduces other artefacts, so it's really not worth it to get those extra few lines.

Edit: shaddix already answered it, oops!

However, the motion resolution tests run on the TVs are only thin black/grey bars on a grey background. I would argue that the Phosphor trails produced by a PDP TV have a negative effect on motion, which the test doesn't show up.

From recent hdguru.com impressions of 2010 Panasonic 50VT20:

"The FHP disc motion resolution test provided excellent results. Enabling the anti-blur mode made the test pattern rock solid and exhibited full 1080 line per-picture-height motion resolution. The moving sign and license plate tests confirmed a significant reduction of phosphor lag. There were no signs of phosphor lag when we switched to viewing an action movie on Blu-ray disc."

http://hdguru3d.com/index.php?option...news&Itemid=59

"Anti-blur" is frame interpolation. Reading hdguru closely, it seems to imply that without frame interpolation the VT20 did NOT get to 1080 lines motion res; Gary Merson had to turn on anti-blur to get it.

It's too bad no present-day TV has really brilliant (CRT-grade) motion performance. I guess that's for OLED in future.

Walt, I gave you explanation 12 days ago about the LG and Pannys motion resolution. Here is one of my posts:

You are right ... I must have lost the thread for a few days there when my 550 arrived and was fiddling with bias lights.

Anyway, the recent quote from hdguru suggests that the same situation holds for the '10 Panasonics as well as the '09s, despite the new "fast phosphors" or whatever it is that improves the 3D effect. Bummer in a way, I'd hoped that plasma tech could reduce the blur further, but I guess not.


Edit: Side note, one thing that still puzzles me is the way Panasonic apparently implemented frame interpolation on 60Hz North American TVs, very weird since we usu. only hear about such a feature on 120Hz (100Hz PAL) as on LCDs, Euro Pannys. (The NA 09 Pannys can't really be running at 120Hz, otherwise they could easily have implemented 5:5 for 24p; they must be effectively converting 30fps to 60fps and going at 60Hz.)

All purely academic however. I stand corrected on this question!

My personal opinion is that, also this year, panasonic plasma up to the G20 series (I have no infos about the V20, and I don't take care of the 3D VT20), are cheap plasma display as well as they were the past year, and as well as many others of other brands.

I don't give a toss about their "new" features. That one that is now creating that floating-blacks problem (i forgot its marketing name) it is not defeatable; the "super resolution" is only an edge enhancer; the "Infinite black" is another example of useless feature, and so on.

Until they will continue to use their V-Real video-processing developed in-house, I can't see how much good those plasma can be. After so many years, even this year the G20 is not able to do a good deinterlacing, and that is a REAL shame. And you know all the other strange things.. no 96 Hz on 1080p/24 on the U.S. models, GG still present, color banding still present, and so on.

Pioneer was another story.

I agree with this. What I hate and don't fully understand as to why TV manufacturer's continually spend millions, if not billions, on making their TVs thinner, larger, run more apps, search the internet, and so on without focusing on the PQ first. It seems every year we have the same issues with motion problems, color not being accurate, less than ideal blacks, uniformity problems, and requires professional calibration to achieve acceptable quality. It amazes me how much of the features we have to turn OFF to get the best picture. The phone industry is just as bad. They keep marketing how many apps they run, number mp3 files it stores, the number of Mp camera it has, email service, watch movies on, and so on, but yet the basic purpose of the phone, the phone call, does not improve. You still get dropped calls, lots of static, un-natural sounding voice, and no or weak service. With TVs, now they're pushing 3D, which personally, I would much much rather they move to 4K2K spec first. Let's abandon the hundred year tech of 24fps movies and move it up to 60fps. It would eliminate a lot of issues we have with home TV viewing since there would be none of the tricks to make it look right.

okay enough of the rant... I need more coffee this morning.

Sorry for being ignorant, but I guess everything you guys said about Motion Resolution means that todays technology just isn't capable of displaying full 1080p motion resolution?

I never knew about this before, I just figured a 1080p set was 1080p for everything. Hey, I learn something new everyday!

Has anyone confirmed with LG or the owners manual that either the PK550 or PK750 do 3:3 pull down in order to process 24p?

According to the specs on LG's site for the PK550 (and most likely the PK750) is that is does do 3:3 pulldown for 24p playback.

Both do, and do well according to Chad B's pk550 review

Many people have mentioned that the LG's have no anti-reflective coating at all...so my question is, what is "protective skin glass"?

I think its supposed to help eliminate the double images seen in some multi-layered glass plasmas. its supposed to help some with glare as well, but as you can see from users photos, it doesn't do much.

Hey all:

This is my first post (although I've been lurking for months, ever since I decided that not being able to read any Mass Effect 2 dialog justified replacing the CRT), and I wanted to start by thanking everyone for your reports on and honest criticism of the pk550. It's refreshing to come in here and not have to slog through the Panny vs. Samsung debate.

A couple of things on my mind:

1. No local retailer (Denver) carries this set. Both BB and Ultimate Electronics gave me some FUD about parts availability and service time. Any long term LG owners care to weigh in on reliability? Anyone have an idea on why LG sets aren't in the big box stores? Is a Square Trade warranty worth it? (I know this was asked pages back, but never really addressed.)

2. No component audio out? Boo.

3. A link was given pages page to a site where you can download a calibration dvd. Is this useful without a printout to compare colors against? Any ideas on how to get ahold of Avia/DVE without purchasing/Netflix?

4. Walt - I'd appreciate some more info about your bias lighting setup, including pics. How did you mount the light? Would a longer strip fixture be necessary for the 60"? Have you had any ideas on how to improve the setup since your initial post?

Looking forward to your responses...

They definitely have some sort of coating - at least the Euro PK990 I reviewed did. When you look at extreme angles, the entire screen gets an almost "foggy" look.

I'm having second thoughts about my 58b650. I am with in 30 days to return due to some buzzing. My question is how does this compare with the 650, and would you return a 650 for this TV?

You would lose the internet widgets. I think the 650 may have a better AR coating, so you might see more reflections on the pk550 in a bright room.

the upside is you pick up a couple more inches with a 60". and no real buzz issues that i've read about yet.

The 750 and 550 I have had in my home are mirrors when turned off, coating is likely just on the 9x0 models.

My DTV DVR buzzes MUCH louder than my 60pk550, just from HD noise. I'm really sensitive to this, and the LG is very quiet. You'll be fine.
