Only Set_Up and Vy potentiometers were trimmed.

Thanks for the report! What did you feed the TV with while doing the tweaking - 24p, 50Hz or 60Hz? If you tested them all, which one was the hardest to get stable?

An X-rite i1Display 2 meter was taking constant measurements of the MLL while I trimmed the two pots. AVS HD709 BD 'black bar' scene was used to prevent the TV from entering into power saving mode.

I stopped at 0,028cd/m2 and then checked a 24hz source from PS3. The where some pixel misfires, so I trimmed the Set_Up potentiometer bit backwards and checked again - no misfires. All the 50hz inputs tested were also clean of misfires. So, the final result was 0,034cd/m2.

I think there is still room for a small enchantment, but this wasn't my tv set and the time was rather limited Someone already got below 0,03cd/m2 with more careful trimming.

Fyi for those of us using English units, 1 cd/m2 = .292 ftL.

So .034 cd/m2 = .010 ftL

I got .007 ftL with only set_up/dn but only in 60Hz mode. My 24fps is much higher at .018ftL. TV is USA 60PK540.

Sounds about right, a properly calibrated stock PK/PX950 should begin with a slightly better contrast ratio to than the PK550 (although reports have varied) and I've achieved a lower black level than the Panasonic ST30 which I believe is at .006.
Just trying to decide if I stay with the results that I got with just the Set_up or take er down again and fiddle with the Set_dn to see if I can get it even lower.

Your results are already excellent, but if you want to experiment further perhaps you should buy or borrow an i1 probe to guide you. Otherwise you will always be guessing at whether your new black is lower than before.

You can get one new here for 149. I'm sure there are used ones too. I have this one and it works great.

Not too sure I want to go lower, I've already knocked my Guinness over 2 or 3 times while watching movies, that never happened prior to tweaking.

But you're right, without a meter ones always guessing or wishful thinking.

According to current information on the PM970T plasma for 2012
"The new plasma series can, thanks to a new type of phosphorus, improving image quality at several points. With the new Super Black Panel technology is the black 40 percent darker than before, and with a new algorithm improves the contrast so that the colors are brighter and the blacks are darker."

Well we know LG can produce much lower black levels, but will they, the proof will be in the pudding

This doesn't actually tell if the contrast is better in ambient light conditions (new filter) or they've messed with the pre-discharge circuits to produce lower MLL.

Panasonic's claims appear more rewarding.

"the VT50 series, offers some of the best contrast, color saturation and black levels I've ever seen in a TV at a trade show demo"

"The black level improvement can be attributed to an enhanced pre-discharge control that enables the panel to get darker and reach these black levels faster than previous models."

Isn't that what we're doing with set_up/set_dn? Enhanced pre-discharge control? :-)

Judging from the information Panasonic has already released, it seems that the consumer line in 2012 will be using same technology as the professional / custom install series. There was actually a picture posted earlier here on avs, which shows the difference in MLL on 55GT30 (left) and 65VT50 (right).

Definitely. I don't know what that set is on the left, but it needs to have its set_up adjusted ;-)

I was finally able to get my Eye One LT to produce a useable and sustainable reading on a 0 IRE test pattern using Color HCFR. Honestly, I'm not sure what I was doing wrong before (I've never had issues like the in the past), but now I never get the "No data from sensor message" at all.

Well, the results are quite impressive. I measured my 50PK550 yesterday a few times over the course of the day. The 0 IRE read a consistent .005 MLL. I'm amazed at how low that is. Overall effective contrast has almost quadrupled, going from 1900:1 pre-tweak to a little over 7000:1 post tweak.

I initially thought that maybe I could get it a little lower with a bit more tweaking, but I decided to not attempt it as my OCD personality would never let it rest (which is why I kept at it with my Eye One LT). .005 is very, very good if you ask me. I was actually impressed with the way my greyscale and primaries/secondaries have held up. It's been about a year since I did my last calibration, and I've decided to hold off on the calibration until my TV replaces my old projector in my theater room. But it looks like I'll just need to do a few things to get it back into spec. My gamma is still spot on at 2.20.

Great results! Is this measurement at 24p or 60hz?

This measurement was done first at 24p, and that's where the .005 reading was obtained. My 60p measurements were slightly higher at .008. I know it should be the other way around, but I'm one of the few that get slightly lower MLL at 72Hz. I don't know why that is but I'll take it.

None actually. I rechecked the pluge pattern on the AVS disc as well as DVE HD Basics and my brightness didn't need to be adjusted at all. I believe it's currently 52 for my PS3 and 50 for my 360 (both calibrated with my Eye One LT in Expert 1 and 2 picture modes). Going any lower on either picture modes results in the 17 bar on the AVS HD brightness pattern disappear completely, which isn't what you want.

A question was asked earlier in the thread in regards to my backlight setup. It's not as high-end as it may sound. I use an 18-inch fluorescent under-cabinet light with a 6500K bulb (both purchased at Wal-Mart). I fabricated a housing for it to not only help it sit on my TV stand, but to control light spill. Having a glossy base for the TV stand makes for some really bright reflections. The light is nearly against the wall, so spill is now kept to a minimum and there is a nice, light "glow" coming from behind the TV. A local friend has an Idealume backlight that I compared it to. My DIY version is not an exact match to his 6500K backlight, but it's so close to my eyes that I think anyone would have a hard time discerning a difference if not compared directly.

Hey BB,what tweaks did you do on your pk550.I have had my 50pk550 since may 2010 and have noticed the black level has gone up.I found this thread and have read through it but it seems that every one has a little different method for the tweak.I love my pk550 and have contacted Chad B to do a pro calibration but if I can get the results that you and others have gotten I may hold off on having chad come by.

thanks,Uber.

My pv450 has lower MLL with 24p as well, That's why I was curious.

My experience is that the MLL tweak has no significant effect on the calibration except perhaps the slightest adjustment in brightness (+-1).

However, I would imagine Chad would be very interested in the success we've been seeing with these pot tweaks. You may want to ask him to perform the adjustment for you as part of the calibration?

Most people reporting lower MLL at 24p seem to have a 50" model. However somebody last week had this same on a 60". Was that you lifesun?

I wish I could get my 24p lower, but I can not.

I finally go around to measuring it. It is slightly higher at .009 FtL.for 24 hz source (compared to .006 FtL. for 60 hz source). This is for a 60px950.

It would be informative to know which sources are being used, for Blu-ray I’m still using a Sony BDP S-500 and for streaming Netflix the Apple TV2 . Not too sure I’ve noticed a difference in MLL when switching between the two on a regular bases but a few times with the Sony and Blu-Rays I’ve noticed a slight shift in levels, not huge but noticeable even though the LG showed 24p/1080p each time as the source.
What is interesting though while viewing my brother’s Panasonic ST30 there was a major shift with streaming Netflix, especially between the Apple TV2 at 720dpi and the X-box at 1080dpi, the Apple TV was black but the X-box showed a very noticeable rise in MLL, like changing the brightness setting from 50 to 75 for example, Blu-rays on the X-box looked fine though.

Hi Kadajo

We all want that, 0 black.
Each set is different and results will vary, photos unfortunately can never tell the real story.
On my PX950, viewing black slides the screen is just a slight notch above 0 black before going to black (one only gets a second or two to see this), alternating between a black slide and a color or white slide, the black slide will of course appear as if the set has turned off as the eye needs a few second to adjust.
In any case you will get an improvement in MLL with the pot adjustments, how much is hard to predict.
