The Official LG xxPK550 Owner's Discussion Thread [no price talk] - Page 89

http://europa.eu/rapid/pressReleases...guiLanguage=en

It has changed in the EU since july 2010.
It comes down to tv's must be more effecient then the current (written in 2009) average,or they cannot be sold in the EU.
In 1 april 2012 they must be 20% more effecient.

If i had knew this earlyer i would have gone with LED instead of the plasma,i find it disturbing that scorching deserts look like it's going to rain,because of the dimming effect.

Any ideas on how the PK550 compares to the PN50C7000?
I am trying to decide.
Which is a better set for PQ?

Thanks

Strange, mine is very white. Very far from Gray anyway. Didn't think my 60 inch would be this white, and I have to lower the contrast just because else the white is too blending.

my problem with the tv is that I still can see patterns in the tv when the picture pan. like spots and lines with higher contrast than the rest of the picture. And I've used it about 200hours now, LG wants me to wait until 400 before changing it. Anyone else noticed this?

Hi all,
its my first post here.
I baught 50PK550R two and a half years ago, no dead pixels and no special problems.
I watch only normal content with no black bars and no static images (only menus).
When i whached TV yesterday i saw that the lighting of the screen is uneven
like clowding in lcd displays.
i took some pictures during white wash and these are the results:
the first image is the original photograph during white wash

the second image is the first image after contrast enhancement in photoshop.
here you can really see the unevenness

and this is the histogram of the first image showing 0.9 ratio between the darkest to the brightest colors.

is this normal?
should i get it replaced?
should it go away?

Thanks for the answers

I wouldn't say it's normal for plasma. But it does eventually go away after many hours(hundreds). All these PK sets do this.

Also my deserts don't look like it's going to rain, ABL isn't nearly that bad for me o_O

I am seriousely considering this TV. I live in a efficiency apartment that is one room. With the way the TV would go, it would be facing a window in front of it and a window on the right side of it. However, I work a graveyard shift and I pretty much would only be watching TV at night on my nights off. So, my main concern would be the ceiling fan light fixture. I have 10 foot hi ceilings and my TV would be placed on a HDTV stand that is low to the ground. Would the ceiling fan lights be caught by the TV screen?

Put a mirror where you will locate the TV. That's the "glare/reflections" you will see. Overhead lights are a no-no for any type of critical viewing anyways.

i've been compareing the two myself at the electronics store. the pk550 has way better colors and is more vivid. the c7000 is way better for less reflection, and a slightly smoother picture, and little more depth. that being said...i myself am leaning to toward the pk550 because the colors are just so much more beautifull and vivid(without being artificial which is a big downfall on the c7000 from what i witnessed).

this was viewing content on a 720p feed(which wasn't that good)...not 1080p.

i don't have a 50 inch mirror. but the way that sounds the only option for watching pk550 is in the dark. is this so?

Unless you don't mind staring at yourself in the shadows of the picture lol

let me ask this so I can get an idea.... I just got rid of my old tv. It was a Sony 27" Trinitron. Would the PK550 be more reflective than the Sony trinitron I had?

It is indeed more reflective than those Sonys. My PK550 replaced a 36", or maybe it was a 34" HD trinitron and I find the LG just as, if not more, reflective than my old set.

Shaddix was this a reply for my previous post or someone elses? (Hope it was for mine)

I just purchased the C7000, and am thinking of returning it.
The picture looks like what some say is a soap opera effect.

years or weeks ?

I think he replied to both of us because we asked the same question i think.
look at the photos i posted earlier, is this what you see?

You might try talking to the people in the C7000 thread and see if there are settings you can adjust to lessen that issue before making your final decision.

yeah that's correct


re: C7000, turn game mode on then off to disable soap opera effect

Ah ok. Sort off, the patterns I see are more formed as smudged lines (both vertical and horizontal). The vertical lines are visible when the picture pan sideways and the horizontal when the picture pan up and down.

It's easy to spot when watching football (soccer), or when watching a pan over light surfaces in a movie. When using burnin patterns I can also see the patterns, easiest on light red and green colored ones.

I meant use a mirror to "test" the location of the TV. What you see in the mirror is what will glare off the TV once it's located in the same spot. i don't think the glare is bad and my living room is relatively bright.

My living room is attached to our dining room. Our TV is in one corner between 2 windows on one side of the living room while an overhead hanging light and 3 windows reside on the opposite end in the dining room (approx 30 ft from end to end).

Natural lighting is controlled by white blinds and do a good job of reducing reflections on the screen during the daytime. The overhead light in the dining room actually isn't much of a problem when it's on since it sits higher than my viewing angle when watching TV and there is no direct glare.

We do, however, have a lamp that sits to the right of the sofa on an end table that is positioned right in the middle of the TV from my main viewing area. This lamp CANNOT be on when watching TV because it is all my eyes will focus on. It's not so bad during the daytime (when you don't really need it to be on), but it's horrible at night. My wife likes to read on the love seat while I watch TV on the sofa (you actually can't see the glare from the lamp when watching from the love seat, but it's at an awkward angle to the TV and the sofa is the sweet spot) and she needs that light on.

An easy fix would be to move the lamp, but it's plugged into the only outlet in the living room controlled by the light switch. We are looking for another end table (that has to match our current furniture) to put next to the love seat where we can put a smaller lamp for night time reading that won't disrupt our (MY) TV watching.

P.S. Wow, I apologize for the long post, but just wanted to relay my experiences in regards to glare and lighting with this TV.

I did a lot of researching before buying this TV and this thread made me a bit nervous about the glare the set has. It is not nearly as bad as I thought it would be. There isn't much difference between this set and my six year old 32" CRT. If anything the pk550 is seems less reflective when on because of it's higher light output.
There are sliding patio doors and two windows (totaling ~12 feet long and 7 feet tall so roughly 84 square feet of glass) about 10 feet from the TV. These are perpendicular to the TV and face north. Granted I don't have direct sunlight pouring in through the windows but there is still a lot of light during the day and I don't have any major problems with glare personally. I love this set! (more than my girlfriend... at least according to her )

I just installed a HTPC for my 50PK550. One thing I noticed is that my TV has varying brightness.

When I first bought this TV, I checked for stuck/dead pixels with a completely white image. I found that the whites aren't really white. I was worried.

Now with my HTPC, I observed that it seems the TV automatically changes the brightness depending on the image. If the image has a lot of white, it'll lower the brightness. If the image is dark (blue, black), the brightness is increased. The whites look white. You can easily see the change in brightness. For example Windows 7 defaults a very blue background. As soon as I go on the internet, you can easily see the taskbar's brightness go down.

Any way to defeat this stupid feature? I like my TV and my whites bright and look white.

Thanks.

After having excellent luck with my LG 50 in plasma I bought 3 years ago I decided to upgrade to the 60pk550. It is being delivered on monday. I have been reading through a bunch of these post and have just confused myself immensely. Can I reasonably just take this tv out of the box and watch it? If not what settings do I need to change? I would really appreciate any input! Thanks

Check for automatic contrast settings on the display device as well as in the display card control panel.

It's an issue with the technology, all plasmas have it.

im reading, most lg tvs. come with picture wizard! enables you to tune the tv pretty close to the d6500 standard.

impressive. ordered the 42inch pj350. should be here friday. pisses me off because its in VA, basically an hour away. i can't go in pick it up! they don't allow you to. it's gonna take 2 days to bring it an hour.
thats slow if you ask me. but friday is gonna rule.

For those considering this set for gaming, I figured I'd post this. This is in regards to both IR (image retention) and lag.

I re-calibrated last week with my i1 LT and set contrast for a peak light output of 40ftL. For reference, contrast is set at 86 I believe. This also included a 20-point calibration of greyscale (which will get posted soon, just busy) and an end result gamma target of 2.35 (I posted the wrong number before). I know 2.22 is a reference (some say preference) but I'm happy with the gamma at 2.35.

Anyway, I've been gaming pretty heavily on it the past few days. Lots of games with bright HUD elements. Yesterday I played Left 4 Dead for about 4 hours straight, no breaks and no color wash (though I left orbiter on). After that played some Crackdown 2 last night for a few hours without changing the HUD opacity. Again, no breaks and no color wash with orbiter on while playing. After finishing up, I let the color wash pattern run its 15 minute cycle and power down the TV.

So I turn on the TV today and guess what? Absolutely 0% IR. I mean none. I was looking hard, as well. The only thing that showed up was the "NO SIGNAL" bar. That went away with a quick color wash. Needless to say, I'm impressed. I also want to mention that I played a lot of games on it within the first 100 hours, always ending with the color wash cycle and power down. Maybe that has something to do with it.

Also, I've tested, tested and tested and while the HDMI input may have more lag than the VGA input, I can't tell a difference. I tried various genres as well, some shooters, some RPGs. Nothing. Perhaps I'm not susceptible to it. I'm coming from a 3 year old Westinghouse LCD that I had no problems playing on. Then again, I do absolutely no competitive multiplayer, just single player and coop campaign. Keep that in mind as well.

So for those considering this set for gaming, I'd say at least give it a shot. Make sure to buy from a store with a liberal return policy just in case. I don't think you can go wrong with this TV unless you have a really bright room as reflections may be the only hindrance.

I saw the 50 inch PK550 at Fry's tonite, and I didn't notice any "ridiculous" reflections. It seems that the reflections of this TV, is the biggest downfall to it, but I didn't really notice it. With all the lighting in the store, wouldn't it be really noticeable? Or maybe there is just too much stuff going on in a store that it's hard to tell?

I probably should have asked the guy for a chair, and turned off the tv's on each side of it, and look at it for a awhile and try to look for the reflections, but I didn't think of it at the time. Maybe I'll go back and try to check it out again. Does Best Buy or Sears carry this TV? I want to see it a couple of places and see if the reflections are going to be a problem for me, but I don't know if a store setting is going to be misleading for me.

It's most likely the demo content combined with the torch mode settings. I doubt there was anything dark being displayed on the screen while you were there. The light output from the set can overpower any reflections if it's turned up enough. Next time you're in there, turn the set off and you'll see how much of a mirror it is.

@Big Brad: Excellent news about the IR(or lack of that is). I have been too chicken to really push mine like that so far, but I have been getting a little more relaxed about leaving things paused on the screen for more than 20 seconds.
