2011 LG XXPV450 and 400 Owner's Thread - Page 13

post #361 of 844
This thread seems to be more active with people adjusting their pots. I have the PZ950 and was one of the first few to attempt the potis tweak on it. It made a noticeable difference, but I am about to try it again with the findings in this thread.

Based on my hours of tweaking last time, I think I can get it inky black this time with the way you guys tweaked it. Keep in mind I had massive artifacts when set-up was turned all the way up on my panel. I'm going to try again with Vy and stock Set-Dn and see what happens. Probably will happen this weekend.

This is all a bit bizarre.

I'm happy that people are able to improve their black levels on these sets but it made me think: if it is just a matter of tweaking a couple of nobs why don't LG do it themselves before the sets leave the factory? LG obviously appreciate that good black levels in a plasma is a BIG deal and a big selling point and realise that once released their plasmas will be reviewed against the competition. With black level being the single most obsessed about attribute of any plasma you would think LG would "dial in" as much "blackness" as possible... but it would appear they haven't?

The most obvious reason why LG plasmas have a higher MLL is that it is the nature of the panel and circuitry LG use and that is the limiting factor but I wonder if LG aren't just taking a pragmatic approach with their panel factory settings in the knowledge that 9/10 people who walk into a shop to buy a new television don't have any knowledge about MLL, grey scales or anything else and just buy what looks good and is at a good price. Let's face it not everyone in the market for a new plasma is a videophile who will spend hours on the net researching their options.

Every AV forum I have visited is full of threads with titles like: "fluctuating whites", "rising blacks", "floating blacks", "buzz" etc, etc but always in relation to Panasonic and Samsung plasmas; I hardly ever see a thread dedicated to specific problems with LG plasmas. Maybe it has got more to do with demographics than panels but I find it interesting.

I'll soon be buying the 50PZ950 to replace a horrible 46" Samsung LCD and if it is half as good as my old '08 LG plasma I'll be more than happy.

Sorry if this was off-topic

Maybe we should start a LG Potis Tweak thread, I'm not about to touch my PX950 as yet, but after getting the PX my PG25 from 2008 definitely pales in comparison.
For those with the technical know how what exactly are we adjusting with the Set-dn and the Set-up, is it just the amount of current applied to the panel?

For those how have not seen it, most Panel Alignments are listed under each model here.

You are completely correct. I sold my LG 50PS80 because I wanted better black level(no problems at all). Before I could try the potis tweek, my wife had sold it. So I ordered the LV9500 LED. Sweet tv, mine just had a couple of problems, so I returned it. So now I've been looking ever since. Now that everybody is doing this and with good results, I may dip into a 60PZ750 i've had my eye on.

And yes to SARGE, your television looks quite good. How is your fade to black? I am very curious what that looks like on your television.

Honestly I believe that LG sets specs that are stable for a certain panel and ships them out using those specs. They don't take the time to tweak each set based on individual panels and voltages.......I would assume this would be to costly, at least on the lower and mid level sets. So we get some people that seem to have high MLL, and some have lower MLL and are perfectly happy.

In my case, I knew I was buying a budget set, I was going for the biggest size I could afford at the time. I read all about the higher MLL on the LG sets, and took the plunge anyway. And I was happy, especially for the price I paid. Plus, LG does so many things right in my opinion compared to other sets, color and motion handling for sure. Then I just happened to read about the potis tweak, and well the rest is history, made my purchase even that much better! My wife watched the film Beastly last night, was almost finished when I got home from work so I saw the last half hour or so. That is a very dark movie, and it looked great!

anyone been able to unlock the service usb port on this thing?
post #367 of 844
After changing my settings I noticed a flickering white pixel that was not there before. I changed the settings back to stock because of bad artifacting. The artifacts are gone but the white pixel is still there. Is this the pixel misfire that was mentioned earlier or is this a stuck pixel?

Service menu can be unlocked via a harmony remote to send the code I believe. I've seen it mentioned in the forums here before.

Hi everyone,

First, have to say that right now I'm still trying to take in all the awesome from my TV. I upgraded from a Toshiba 37" LCD (720p) so to go to the 50PV450 was... just, wow.

I dislike the glare, and I need to tint a few windows to help reduce this problem, but after about 6pm it's just perfect

So now for my few questions...

1) I have never seen 24p outside of the samples in the stores, so I was really excited to try that at home... But I'm confused about a few things, hoping that I still have true 24p.

Right now, I'm using the following set-up:

PS3 --> Pioneer VSX-819H K --> My TV via HDMI (naturally)

My 24hz is set to Auto on the PS3

When I hit "Info" on the TV, it shows 1080p/24p

HOWEVER, the "Film Mode" setting is greyed out, and I can't do anything to turn it on. I was ASSUMING that it was what turned on 24p.

That said, I THINK 24p is working, the panning does look sort of smooth, and things look a little more crisp, I THINK. I'm not the best at figuring this out..

I'd appreciate any help

2) Also, my wife has told me that she officially hates the stretch mode when watching 4:3. Since we have kids and are watching tons of classic shows, they're all in 4:3. I was a little disappointed that there weren't better zoom settings in the menus to try and eliminate the bars. When I force it to 4:3, it just puts grey bars on the side and squishes the picture. It's through XBMC on my Apple TV, so maybe it's something weird there...

3) Also, I'm currently watching MvA, but will be watching other movies that have the slight black bars on the top and bottom, which of course leave some IR.

Should I just deal with Zoom modes until the 100-200 hours pass? That's so far the biggest frustration I have with Plasma versus LCD...

Thanks for listening, and sorry for my ramblings

Nick

First time I've noticed that after my Step son played some xbox for a while that now there is a faint image of his EA Sports logo and scoreboard at the bottom of my picture. Will that eventually go away or is that burn-in permanent now? Is there a setting for the input the xbox is on that would minimize this?

I've heard of White wash and color wash but don't really know what that is. I thought at first it was something you can run via the setup menu to help clear that.

THanks!

Put your television on a snow station for 60 sec. I would put it on tv input on my old lg. This should do the trick. I did this with my old Pioneer also.
post #375 of 844
@dysan911 do you have pixel orbiter on.....if yes just watch some full screen tv for about 5min and it will go away.....has the tv been properly broken in....i no its not a must to do it but there have been reports that proberly broken in plasma screens tend not to get burn in and IR that much.....if it has been broken in id dial back the contrast ratio to about 78-88 and the brightness to 45 hope this helps

That faded it a bit but Its still there. If you look for it you can clearly see allot of the info that was on the screen.

Great thanks Rob!.

BTW. I did find where I could turn on the Oribiter in the ISM setting. Is there any reason I should ever want to put it back to Normal? Does the orbit setting reduce PQ or anything adverse?

THanks again guys!

What Pixel Orbiter does is it adjusts the image and or static image left, right, up and down ever so slightly to reduce burn in or IR images in the panel...to some eyes they can not see the adjustment being made but to some who have eagle eyes will notice it move all the time but does not effect viewing....PQ is not effected by this software at all and is a must turn on even if you watch full sceen content....

Onething.....I wish that they had a timer for the Orbiter like how panasonic and samsung have unless it is set to orbit every 4-4-4-1 from factory....if anyone knows if that can be adjusted in the service menu please help and let us videophille junkys know....thanks

I've had the 50PV450 for a few days now and it has shattered my previous misconceptions of just how good plasma displays are these days. I love the black levels!

I've got a few technical questions and I will apologize in advance if these have been asked before. I did a TON of research on this specific model before purchasing and now that I have it I've been trying to go over the burn-in thread that was referenced a few posts back. That thread originated in 2007 and has hundreds of posts of a generic nature so I'm unclear if some of the methods I'm reading about are good for my TV.

So, to my questions...

1 - I'd really like to speed up my burn-in process as getting to 200 hours using my regular viewing habits is going to take longer than I am wanting to wait to watch anything that is not 16x9...and yes, I refuse to zoom my movies to fill the screen. I also don't watch ANY slum-def (patent pending on that phrase but feel free to use it under a creative commons license! LOL). Can I use the built-in white or color shifting pattern and leave those running? I'm reluctant to leave the TV on a HD channel for fear of having a station ID logo burn in.

2 - Is there a hidden feature for me to check how many hours I have on the display?

3 - I applied the tweaks from page 3 of this thread..ummm Blacknoir's settings was it? (sorry if wrong name)...anyways, very impressed with the improvements and all but for the life of me I can't figure out why he wouldn't have used the "wide color gamut" setting?! I am using his recommended setting though. I think this question was asked a while ago but I didn't see an answer.

Thanks for reading!
Cheers

Me again.

I know this thread has stagnated a bit, unfortunately, but I'm noticing a few issues.

First, I have (over the last few nights) been watching maybe 1 - 2 hours of 1.85ish ratio movies. Tonight, we watched about an hour of The Phantom Menace (for my kids!! ) and afterwards, even after spending a good little bit watching other programs, color and white watch... I still notice that the spacing where the picture was inactive is a noticeable amount lighter shade in color.

I'm currently watching some full screen hd programming an I'll try checking it again a bit later, but I wonder if I'm going to have to deal with permanent banding.

I think, like all of us, this is the type of programming we watch and WANT to watch. Right? I refuse to deal with the zoom feature on the TV, to distort the picture any more than I already do with 4:3 programming...

At the end of the day, I bought it from costco and if I even get the slightest inkling that it's a permanent problem, it's as easy as walking into the store and walking out with another set...

But having to lug a 50" tv is so far from what I ever ever want to do.

Just would like some... Anything I guess

hey guys, hello from down under. Looking at getting an LG 60pv250 this weekend. I assume that the POT adjustments for Black levels will work just as well on one of these. The many instructions and advice offered here is well appreciated. However, what is in the end the only adjustments I have to make to make my Blacks sparkle? (for want of a better term lol) Thanks in advance guys.

Freddie,

Offtopic but where are you located? I am in Alice Springs.

I imported a U.S. spec 60pv450. Problem is this t.v. does not work with the PAL frequency range. PAL is 50Hz. This t.v. is 60Hz. My bad for not doing the research. I already have a U.S. 42" lcd which works just fine on PAL. Just figured any new t.v. would work on any broadcast system. Hopefully I can buy some kind of a convertor to watch 50Hz material...

You may be able to go into the service menu to change this.

I wish it would be that easy but I have my doubts. Here is the Owners Manual Appendix:
Power requirement AC 100-240 V ~ 50/60 H
Television System NTSC-M, ATSC, 64 & 256 QAM

Since PAL is not listed I'm doubtful it's available. However, I would love to hear otherwise...

Thanks for posting.

Yes, I tried this today, works like a charm. I first adjusted SET_UP and after that I set my Vs back two clicks, hello deeper blacks! Like someone said before, it's not Kuro black, but it's damn close!
post #388 of 844
Thats fantastic news, cant wait to get one. What direction and how much did you adjust set_up by???

Thanks again.
post #389 of 844
Hi guys,

Just got my 60PV250 yesterday and after reading about the "POT" tweaks im definately going to try that out on my set too.

My question is:

Should i do it now, or wait until after i break it in? How many hours?

regards
Jacob

All the way clockwise you will get to the point you can no longer turn, no problems at all.

@Mylle

You can do it now, this should not be a problem. In fact, it should greatly reduce any IR problems. I see far less IR since I turned my pots, although you will see some clouds everytime you turn on your tv, which will go away in a matter of seconds.
