Ah my bad, I meant too much red in the whites (greyscale).

I should probably stop making comments until I get the i1 and can actually measure the greyscale in and out of the SM

It is a about twice as bright as Cinema, but this is achieved by the awful gamma and a greatly oversaturated green primary, more than in Cinema.

So it is very bright. It has a very deep black. But it is no where near accurate. I wouldn't use it for anything other than gaming.

I am at 90 hrs. and I have continued to raise the Brightness control to avoid losing shadow detail. It is now at 52, though oddly the black level measures the same, 0.008 fL.

Please stop sending me PMs asking for my settings. Here they are again.

Cinema
Picture: 60
Brightness: 52
Color: 41
Tint: -2
Sharpness: 50
Color Temp: Warm
Black Level: Light

I calibrated another of these the other day and these settings were almost exactly the same, though his light output was a little lower. I am getting about 34 fL at the 60 Picture setting. Color decoding is nearly perfect, though the red primary is oversaturated and green is oversaturated and bluish. Gamma is a very linear 2.2-2.3.

The only thing missing from this is a professional gray scale adjustment.

I have to say that I have read this and other TH-58PZ800U threads earnestly after purchasing a floor model set a few weeks ago. As a customer/owner of front projection equipment for many years, I have been involved with calibrations and understand the process fairly well.

Having said that and after experimenting with many of the settings put forth by the esteemed group of diligent Panasonic owners here, the THX settings are completely unacceptable to most viewers in terms of flat, darkened imagery. That is not to say they are incorrect or do not track gamma properly or any of the other problems associated with incorrect calibration. It just means they are not pleasing to the eye even in low light conditions. I have had more than a dozen people over the house to look at this tv and every one has concluded the same thing so it's not a singular preference.

I've plugged in [i]gourmetcoffee, daMaster, nyny69 and StuntMan Mike's settings with Warm temperature and still come up with a less than stellar picture that otherwise should be stunning in terms of technology with eye-popping sharpness, clarity and color reproduction considering an expensive Plasma. The THX settings, regardless of whose are implemented, appears stunted, limited, dark and suppressed.

I have gone into Custom with Normal temperature and reduced somewhat the original presets to like Brightness 45, Color 40, Picture 75 and so on. The image pops and is preferred by each and every one shown the comparison. Is this consumer ignorance? Should people have to watch a dark dull image even when experts say it is at 6500k?

The point about watching the correctly calibrated THX image in a darkened room makes no sense whatsoever. So, we spend time adjusting all this going into Service Menus and the like to have to watch tv in a pitch black room? I tolerate that in my home theater since it is a Sony G90 FP CRT that requires total darkness, but I am not going to have to live with that in a family room environment.

I suppose what I'm seeking is common sense and common ground here. I am not arguing whether or not the THX image can or can't be properly calibrated. I am arguing that the THX image under a Warm temperature is not a very pleasing picture to the eye.

As far as light output is concerned, anywhere from 30-40 ftL is recommended for Plasma Displays. If THX picture mode does indeed offer that much light output, I would say it's adequate. 30 ftL is good for a dark room, while 40 ftL is ideal for a bright room. THX itself recommends 35 ftL, a balance between the two.

The warm color temp may not appear to look as good as normal until you get accustomed to it, but it is the closest to D65 and so it doesn't add a bluish tint to the whites, unlike normal (and especially cool).

Well, I don't have a light meter to tell you whether or not it's hitting between 30-40 ftl. I can tell you I followed the settings instructions to the letter from folks like daMaster, gourmet coffee and others. The picture is simply murky at best.

People do not spend close to $3000 to watch tv in the dark. As I said, I spent $30,000 to do that with my projector, but a Plasma tv should offer something different - namely the ability to watch it in a family room with the odd table lamp on. As I said, I am not arguing whether the settings produce 6500k or not and I know that is the ideal temperature to be at - but whatever it is in the THX Warm mode that causes it - it simply is not as pleasing a picture as the eye popping Normal mode that to the naked eye renders colors maginificently. I think what's happening here is the anal retentive colorimeter guys going for one standard while Mr. TV Watcher is going for another. The latter guy is looking for life like realism popping out of his screen and you can't get that from THX Warm.
post #2285 of 2470
If you watch a lot of DVD's and Blu-ray's, I think you'll find THX Warm to look best but watching regular TV, HD or SD, will have varying results since I don't believe every channel and every program follows the calibration standards of ISF/THX to a T. I find some TV shows look ugly with warm color temp while others look great and then there are those that look just plain average.

The truth is that there are just too many variables and variations in TV programming and as a result, there is no one specific set of settings that will make all TV programming look best. With movies there is a more level playing field, but regardless of settings some movies will look better than others and that has a lot to do with the movies themselves and not your display.

If you don't care about a calibrated display, you can use whatever settings look best to your eyes, but keep in mind this will result in a less accurate picture assuming the source material is following that calibrated standard.

You're at +58 for Picture under Cinema or THX Warm???? Most people are at 100

There is no THX mode for the pz80/pz85u models.
post #2289 of 2470
Mike, your thinking of a different line of Pannys.

For the PZ80 or PZ85, most people seem to be around 60ish up to 65.

So Plasma's level of 58 is right in the ballpark to where it should be.

Any chance you did before and after service menu changes?

I'm both curious on how much one can improve in the service menu and, because I'm not one to enter it, wondered what you came up with for ideal settings on the 80u before doing so.

Currently, I can't seem to go much higher than 50 for picture without it starting to get too bright for my eyes. Seems okay for movies but as soon as I hit the DirecTV program guide, it is just too much.

Color at 41 often seems to push being oversaturated also. Never tried going higher than that either (or moving the tint down).

The above is just done by eye so nowhere near as accurate as others settings.

I did post my SM before and after settings in my earlier post and also the user settings that go with it.

Like I said earlier, before using the i1d2 my grayscale showed green and red tracking well, but there was a significant blue deficiency throughout the entire grayscale. This was creating a yellowish tint for the entire grayscale and resulted in a color temp between 6000k and 6250k.

I cannot provide user settings to go with your SM defaults so the best thing you can do is use DVE or AVSHD709 and tweak your display with the test patterns/color filters. A light meter could help you set picture/contrast but you may also just find a setting that is not too dim nor too bright under average viewing conditions.

Without entering the service menu, you can get a good picture with DVE/AVSHD709 but grayscale will not be perfect.
post #2292 of 2470
Last night I decided to go through a few more rounds of grayscale calibration and while checking and setting white level (picture), I noticed an issue that was present during my earlier calibration as well: when taking continuous readings and observing a 100% gray pattern the ftL slowly drops as the readings update, so much that I ended cranking picture to 100 only the notice the light output was still slowly dropping so that my light output was still around 35 ftL after displaying the pattern for 5-10 mins.

Is is normal for the ftL reading to continuously drop in small increments during continuous measurements with a 100% gray pattern? (I got a light output of almost 39 ftL during the 10-point grayscale measurement at the end of my calibration, however.) I'm quite confused about what to do regarding this issue since the picture level affects the grayscale substantially, especially blue tracking.

Well, I think other members have recommended making adjustments inside the SM and then take the readings outside of SM. Does the picture level drop like that outside of the SM? Are the greyscale readings the same in and out of the SM?
post #2294 of 2470
I made 100% of my measurements outside of the SM. I need to figure out how to get stable ftL readings so that I can properly adjust my grayscale to the right picture level. Any advice or feedback would be appreciated. I'm considering using the 10 point measurement ftL value for 100 IRE instead of continuous measurements, but would like to avoid that approach if possible.

Not necessarily.

My 85u was calibrated by Gregg Loewen of LionAv and was left in the default cinema mode (pic of 100).

He made adjustments in the SM, then tweaked black level and color in the UM.

Pic stayed at 100

Lots of good stuff in here!

I just picked up a 50PZ85U two days ago from Costco for 700$ I'm not kidding it was a flawless openbox that they sold as new with the 90day/2yr costco guarantee.

So far I've been trying everyones settings and the results have been good. I am upgrading from a many years old Pioneer PRO-810HD (43" Plasma Monitor) and am very pleased with the blacks. I still think the colors on my PIO are better but I have had it ISF calibrated by a tech a few years ago.

Does anyone have the service menu settings specific to the 50PZ85U? While it was easy to justify to the wife to pick this panel up for 700$ it will not be easy to justify a 350$ calibration.

I'm also using a PS3 for all my media streaming/bluray with a COX DVR

Odds are you're better off leaving the service menu alone unless you plan on using a colorimeter to calibrate the grayscale. That is the only thing you can do in the service menu in terms of calibration as there are no gamma or CMS adjustments.

What you can and should do is use a calibration disc like the free AVSHD709 or the DVE Blu-ray with red, blue, and green color filters to tweak user settings of picture, brightness, color, tint, and sharpness.

I recently used a colorimeter to calibrate my grayscale and I can say from personal experience that copying someone else's settings or even their offsets is pretty useless unless you broke-in your set exactly the way they did. Odds are that without a meter you won't know the effect of the changes you're making and could end up with less accurate picture than the one you started out with.

http://www.avsforum.com/avs-vb/showt...9#post16013999

This thread is for 2009 models but better explains how break-in and offsets are related to one another.
post #2298 of 2470
Just thought I would mention that if you use the PC input (VGA) you get White Balance and Gamma controls in the user menu.
post #2299 of 2470
Looking at my ColorHCFR Gamma Graph, I have the following:

10%: 1.96
20%: 2.05
30%: 2.11
40%: 2.13
50%: 2.13
60%: 2.25
70%: 2.23
80%: 2.20
90%: 2.27

Average: 2.15

Is this typical for a PZ80U or is it possible to do better (without an external VP)? From 10% to 50%, it appears to be too low. This shows up as too much luminance from zero to about 55%.

I found that a very high contrast setting (+100) would result in lower high end gamma while a lower setting (+49) resulted in the high end gamma shown above. I set brightness at +55 since I was aiming to show all above black information. Would brightness be the setting that would affect the low end gamma? Of course, I can't change it without making blacks gray or without black crush.

He most likely lowered the subcontrast level in the service menu. So 100 contrast in the user menu probably is more like 50-75. Just a guess, but most likely that is what he did so if you ever lose your settings you can just click "restore defaults" in cinema mode and be on your way.

I think the brightness control affects the lightness throughout the whole range evenly, so you can't really adjust gamma with it.

One thing I have tried to correct gamma in Cinema is reducing All-Cut and then increasing Sub-Bright. I found that it worked partially in that some of the mid range brightness was decreased (for instance 50% grey became darker than before) but then it still looked too light in the low end of the scale. Overall the picture just looked a bit stange and didn't seem to have the contrast in the right places. Also the colours seemed to go very bad the more I lowered All-Cut.
post #2302 of 2470
My understanding is that sub brightness and brightness have the same effect as each other but the cuts only affect the lower half of the grayscale. Prior to getting my colorimeter, I had lowered all-cut to 6E, raisied sub-brightness to 815, and then set brightness with a black clipping pattern. This resulted in slightly deeper blacks and the set coming out of black a little slower but on the black clipping pattern, the bars above black were flashing yet barely visible (resulting in less shadow detail).
post #2303 of 2470
Well, if you want accurate gamma you might want to calibrate in one of the other picture modes that has 2.2 gamma as default. Apart from that you could get a video scaler like the VP30/VP50 and convert to VGA so you get the gamma control in the menu.
post #2304 of 2470
My PZ80U has no VGA connection and I'm already using Cinema as my picture mode. Just wondering if there is anything I can do or should do short of getting an external VP.

Everything I've read so far regarding the PZ80/PZ85 has referred to Cinema mode as the mode with the best gamma overall. What mode(s) do you believe have better gamma and why?

I have the U.S. model (PZ80U), which model do you have?

I have the Australian models 50PX80A and 46PZ800A. The gamma is way too low in Cinema mode (~1.8) and this is the same on British/European models, so I thought it must be the same for the US. Looking at your gamma figures it looks better than ours, but still a bit too low. On our models the "Normal" picture mode gives 2.2 gamma so I am going to calibrate in that mode instead of Cinema (still waiting for my Eye-One)

Do you mind sharing your gamma readings from the ColorHCFR graph? I'm trying to get a idea how good my current readings are by comparison. Also, if your gamma is too high in the low end that could explain the lack of details in darker scenes you noticed. Mine is too low in the low end and as a result luminance is too high all the way up to 55% gray.

Reading on the forums the clear choice of video setting is the Cinema option, why? I've been comparing cinema with Game and I have to say that the Game video setting seems to produce a more pleasant picture. It is brighter and more colorful than Cinema where it looks like your looking through sunglasses and it looks dull compared to Game. I'll be getting DVE soon where i'll be able to claibrate both and see which looks better but for now Game seems to be the better option.

Gamma is way off in game, its on torch mode. You wont get a very accurate picture in game for sure. To each their own, but the most accurate picture this tv can present in in cinema/warm with a color around 41, a contrast around 70 and a brightness set with DVE Blu-ray.
