You happen to know the build dates of those Elites?

Buzzard767,
If you don't mind, I'm curious as to the details of the CMS issue you experienced with the 3rd set. smile.gif Also, do you know the manufacturing dates of the 3 sets? And do they have screen uniformity issues when viewing 100% field gray patterns?

I calibrated my new replacement Elite last Friday. Out of the box, the default greyscale readings are MUCH better than the defaults of my old set (pics below). After calibrating the greyscale, I input the same calibrated CMS settings I used for my old set. Although I had to make very small changes, the CMS settings remained pretty much the same as my old set.

After viewing various content over the past weekend, I've got to say that my new set has much better color balance. Colors, especially skin tones, look even more natural and pleasing. Even with the slight green patches issue only visible on an all grey/white image, I prefer my new set over my old set. smile.gif

Hey Buzzard - were you calibrating the ISF modes or the THX Movie mode? When you say non-linear color tracking, does that mean you were not able to calibrate those 2 TVs to the standard, or that you were able to get them to standard but with greater effort? In the end, were you pleased with the calibration of the colors and color performance of the 2 Elites?

Thanks,
JD

Here are default color gamut readings showing Elite's non-linear color tracking. The chart shows the 25%-step saturation sweep readings of the color gamut at 75% stimulus. As you can see, 25-75% points are mostly undersaturated while 100% is oversaturated. As for cyan, you can clearly see issue Elites have with cyan, the hue is way off from 25-75%. Therefore, there is no way to get all points close to their respective targets. The only thing to do here is to pick a point to calibrate to and at the same time try to minimize the average errors. For me, I choose to calibrate the Elite using the 75% saturation points as that gets the 25%-75% range closer to their targets, ignoring the errors at 90%+.

GOT looks so good on the ELITE, can't wait for it to start up again.....winter is coming!

Well now I can't get it to flicker at all. The brightness and contrast are staying constant from scene to scene. I have the same settings now as I did when I started. It sounds like an intermittent problem though and I'm not so sure I'm interested in waiting until it eventually shows back up again. Calling a tech out at a later date only for the problem not to show itself would also kill any chance they would take me seriously.

I honestly can't remember if I have seen this problem. I finally started streaming Netflix. I hooked up digital audio out to my amp, but I can only get stereo out, not Dolby digital. All I can get from the optical is stereo. What am I doing wrong? By the way, I have had no troubles at all with my wonderfully calibrated 70".

No. They were all on walls. I do know that they, along with 4 VT50s, were purchased from BB last August.

Not much to say except it took extreme settings changes to obtain minimal results. Uniformity was okay.

ISF with ControlCal. Tracking was not so good calibrating 100% saturation and it's the reason I nearly always calibrate at 75% sat now that we have the ability to do so. Cyan was way off and I'm looking forward to getting the hours needed with an Elite to do a LightSpace LUT and see if those errors can be eliminated.

I'm a little confused.

Whether you calibrated at 75% or 100% saturation, wouldn't one or the other of those be on target?

Hi All -

Does anyone know if it's OK to use a laser pointer on a LCD TV?

I'm having a bunch of family over soon to look at some pictures (my Dad just converted a whole bunch of old slides to digital files) and it would be helpful to use the pointer for those inevitable "Who the heck is that?" questions.

Obviously, if there's any doubt at all I'm not going to point a laser at my Elite TV with a $9k MSRP!

Thanks,
JD

The chart shows the saturation sweep of the color gamut using Elite's default settings, not calibrated settings. I couldn't remember what mode this was in; it may be either Movie THX or ISF Night.

Here is a calibrated (using 75%) saturation sweep chart of one of my previous calibrations on ISF Night mode. smile.gif

FWIW you better but a ZT60 on day one because just as sure as the sun will rise tomorrow there will be people who have problems with their ZT60.

No set is perfect. Buy what you want and try it out. You can always return it if a problem arises.

I realized after I read your post that you weren't trying to show a calibrated gamut.

But this isn't much better. If nothing else, shouldn't 75% saturation be on target all the way around?

Me too. I was just about to pull the trigger on the 70" until I read about the issues that seem to cropping up lately. To get a killer price you need to order online. If you order online its a one shot deal. No returns. I just can't afford to gamble with $6K.

I'm waiting for the ZT60 as well. Looks like it might be a sweet TV.

Received Elite 70" #5 and green /pinkish blotches continue on this unit too. This time green is in the middle of the screen, and rosy red is on both sides. On top of that, set exhibits fair amount of typical DSE that I did not see before. Best Buy was promising a set from the new batch but I ended up with the set from the same Nov2012 batch and with serial numbers very close together.
A week ago, I started shopping for regular full-array 70" Sharp from a year ago and found 70LE732U from the local guy. I went to see it today and I must say that the screen is perfectly uniform grey, no problem at all. So all that BS about limitation of LCD technology and DSE being on every set that Sharp gave me is just that - BS. 70LE732U is 12 months old set and QC were present at the Mexico facility. I did not buy it because I could not stand the blacks, or lack of black and on top of that viewing angles on the set were really worst that I have seen. Major color shift even 3-4 feet off center.

Thought I would finally make a post in this thread. I have recently been looking for a new TV to replace my nearly 7 year old Sony LCD TV. I am not really the person that has to have the latest technology and often buy closeout deals or products near the end of their life cycles. Knowing that this is usually the best time to buy a TV, with the new models being announced and the current line seeing substantial discounts, I headed out and took a look at what was available. I knew about the Elite TV's from when they were first announced over a year and half ago, but like a lot of buyers I simply marveled at the outstanding picture quality and deep blacks, but pretty much took them off my list because of the high prices, and not really being something I could justify spending that kind of money. So I decided to take advantage of the substantial discounts that have recently cropped up on the Panasonic VT50 line. I want get into price, since it's not really recommended on the forums, but suffice to say I think most people are aware of what many of these flat panels are going for at the moment.

So anyway I took the salesman advice and went with the 65" VT50 (As a note: The Elite's were no longer being stocked at the BB near where I live, and I was told by the salesman that the line had been discontinued and they could not order any more sets.) So it pretty much made my buying decision rather easy, as no other set they had in stock or could order approached the picture of the Panasonic. Skipping ahead I had the TV delivered and setup and used my silver status as a Rewards Zone member to have the set calibrated. First few days were good. Colors looked very accurate, though not with the same amount of pop I am used to, but still the picture was very nice. Contrast was good, with dark areas showing good shadow detail and blacks looking deep. But the more dark content I watched, such as Cabin in the Woods (BD) I started to notice what I could only describe as small white dots in the black areas. (Sorry I am not much of a videophile, my expertise is in audio.) I am not sure if this is what is known as "dithering" or something else. Anyway the problem seemed to vary greatly depending on the content. Also while watching the same movie as listed above, some of the really dark areas descended into a slight fog, instead of the detail that should be there. Note this was not a problem most of the time and it could be a problem with that specific movie or how it was encoded. I am really not 100% sure. But the main problem I had with the Panasonic was that it would flicker like crazy on bright scenes. I tried adjusting the refresh rates, but it still persisted to some degree. Aside from these issues the picture was still tough to resist. On other movies like Harry Potter (last film in the series) the black levels and shadow detail were excellent, right up there with some of the best I have seen. Interestingly on this film, I didn't notice any of the slight gray fog in the shadows, and saw plenty of detail. But I did still notice some picture noise on the darkest of content. Best way to describe it, was like the white dots were dancing in the background. Unfortunately my wife experienced the flickering also and stated that I should contact BB.

I went back to the store and spoke to a different salesperson and stated my observations. He recommended that I look at a comparable LCD flat panel. Looked at the displays in the MHT department. Then I overheard another customer in the MHT who was apparently purchasing an Elite TV, 70 inch in size. I was confused because the other salesperson indicated that they had no stock of the Elites. The salesperson stated that MHT was selling the two demo models they had setup. I went over and watched the 60 inch version. Picture looked incredible with the content that was on the BB demo reel, but I asked the salesperson if I could come back the next day, which was Saturday with my wife, and if I could bring some discs with we to get a better idea of just what the TV had to offer. He agreed. So next day I brought in a few blu-ray disc tiles, including the same copy of Cabin in the Woods that I had watched a couple of nights earlier. The salesperson, who was wonderful BTW, hooked a blu-ray player up to the TV and we popped in Cabin in the Woods. I skipped ahead to the very dark scenes that I has seen on the Panasonic. The first thing I noticed was that the white noise in the dark areas was gone. I could also see the fine details in the shadows that were a slight gray fog in some cases on the Panasonic. Most importantly I saw no flickering, which had really driven me crazy with the Panasonic. For what it's worth the screen looked perfect, at least to my eyes. The colors were certainly more vidid, and perhaps slightly more saturated on the Elite, as compared to the Panasonic, and I was told that a calibration would take care of that to a degree - though even the salesperson agreed that the colors would not be quite as accurate as the Panasonic. So it really came done to which little caveats I could live with. In the end the floor model was substantially discounted and I decided to take the plunge.

Please forgive me for the incredibly long post, I do tend to ramble. But BB will be swapping the sets early next week. I will post my more thorough impression then and of course any problems with the set that I notice. Though I will go ahead and state up front that my impressions of what make a good picture might be little help to many potential buyers. For example, I don't mind slightly more vivid colors and I couldn't tell you much about the grayscale or any other issues others may have noticed. But I will post my findings anyway for anyone who is interested.

White sparkles in dark areas sounds a lot like a loose HDMI or bad HDMI cable. Check to see if both ends are fully inserted.

Thanks Jim. I have since disconnected the Panasonic and put it back in it's box as it will be swapped this weekend. It is very possible that it could have been a problem with connection, though I used an older HDMI cable that seemed to work fine with an older Sony set. It could also be that I an not accurately describing the problem. I should also point out that I have very little experience with Plasma sets so it could have been something that I noticed that could have gone away with a proper setting or with a little more time for the Plasma to break-in. BTW, I still believe that picture was incredible.

Guys I am trying to keep up with the new issue while on vacation. Is the latest color problem just on the 70? I have the 60, but am upgrading to the 70 next week when I get home. This is through Best Buy in Illinois. Thanks Jon.

And it looks like Nov. builds may be the last. I really think their might been some QC issues on the Nov. builds.

Matts, interesting post, thanks. Good luck with your new display.

FWIW, I too noticed exactly the issue you described with my 60" Kuro plasma. However in my case it was only noticeable in those dark areas at closer than normal viewing distances, not at my regular seating position. But it was there. In my case it was not an HDMI cable causing the issue as I had swapped it out.

Well, some of the previous problems I was seeing have cropped up again (pulsing and some blacks turning purplish-gray for a second or two). However, it is only intermittent and a tech isn't going to sit there and watch a whole movie waiting for the problem to show up. If this were a $1500 TV I wouldn't mind it but even at 27% off its a $6300 TV after tax.

I've already gotten used to the larger size, so going back to my old 52" will be difficult. But I guess I will wait on the next generation of TVs

EDIT: On an interesting note, I finally hooked up my Darbee to the Elite that I was previously using on my projector. I was surprised that it made a significant improvement to the picture quality. It made only a marginal difference in PQ on my projector and I thought it would be hardly noticeable on the TV but I was wrong on that.

blacks turning purple is a really strange one that I've never seen or even heard before, and for you to get two sets to do this just boggles my mind. Sorry for your problems, maybe there are quality control issues with the latest builds... Sad really as this is such a gorgeous display.

Hi Matts and ty for sharing your story with us, a bad HDMI cable would not cause that kind of issue and in studies showing you would not even get a picture if you had a bad HDMI cable. It was most likely your Panasonic Plasma set causing the issue since you have ruled out poor source material on the Elite. I think you made a wise decision going with the Elite, big congrats and welcome to the Elite club! biggrin.gif

The color problem you're referring to is not really a problem as you put it and would not be something you could see outside of a comparison test unless you are watching very specific source material and have a professional calibrators eye. So the issue effects a specific luminance value that is extremely hard to see outside of a comparison test side by side with a very accurate display. And yes it effects both size Elites. cool.gif

Might be, my heart goes out to those who have got a defective set because this Elite really is the best display I've ever seen to date. In fact I don't expect anything to be better in the near future until they perfect OLED way down the road cool.gif

Sorry for the confusion, it's just this one set. When I ordered this Elite I had already made the decision that it was a one shot deal. Either it it was going to perform superbly or I stay with what I have. The blacks turning purplish gray is only for a second or two and it might happen once out of every two blu ray movies. But it's always the first 2 seconds of a scene change. And I've seen it occur both in blu ray movies and the Netflix app so it's not the source but rather something strange going on in the TV.

The flickering is more constant though and usually happens several times per movie. Usually in a scene where there is partial brightness. It's very similiar to what it would look like if there was a candle flickering in a dimly lit room.

That certainly sounds like the pulsing issue. I'm not sure if your display has the latest software update. Sharp sent one out awhile ago that greatly reduced this issue.

The purple thing is truly bizarre. I've never seen anyone comment on that on either the 60 or 70.

Best Buy was promising a set from the new batch but I ended up with the set from the same Nov2012 batch and with serial numbers very close together.
A week ago, I started shopping for regular full-array 70" Sharp from a year ago and found 70LE732U from the local guy. I went to see it today and I must say that the screen is perfectly uniform grey, no problem at all. So all that BS about limitation of LCD technology and DSE being on every set that Sharp gave me is just that - BS. 70LE732U is 12 months old set and QC were present at the Mexico facility. I did not buy it because I could not stand the blacks, or lack of black and on top of that viewing angles on the set were really worst that I have seen. Major color shift even 3-4 feet off center.

I am beginning to think that the new batch from Nov2012 may be using a different panel? I have had 3 different 70s in the past 15 months and the first two do not have the green/pink patches whatsoever, perfect uniformity. My lastest replacement set is a Nov2012 received last week and it definitely has green/pink patches. Can you see it most of the time? No. Noticeable when there is content with large white/grey backgrounds. Would I return the set if I could? You betcha. Unfortunately, I can't. I will have to live with it.

Couple of things this new Nov12 set is better than my previous 2 sets. Much better greyscale out-of-the-box on both Movie THX and ISF modes. Also has better color balance after calibration.

I don't think Surge was talking about the cyan color issue. The 'latest' color problem is the green/pink patches on the Nov12 sets. So far, I believe all Nov12 set owners have reported seeing this.

I knew someone was going to ask this question sooner or later. wink.gif

Yes, I could have moved all the 75% perfectly into their respective target squares, BUT that would not have resulted in the best quality image (at least on the Elite). smile.gif You CANNOT rely just on charts and numbers when doing a calibration. You will also have to view real world content to verify the calibration produces correct colors output, then adjust the CMS controls accordingly. The Elite does have color tracking issues with most of the colors so when calibrating the set, you will have to average out the range of errors and make sure not one section (ie. 75-100% saturation) is not totally off its reference while sacrificing some error at the middle to lower ends.

The chart I posted also only represent the hue and saturation of the colors, no luminance (the 'value' control in the CMS) values. The biggest challenge is, the Elite's CMS controls are not implemented correctly. Changing hue and saturation for one color may also change its luminance, changing red settings affect magenta, changing blue settings affect cyan, etc. So what I had to do is determine the best settings that averages out the lowest errors, watch reference content, then go back and adjust the CMS again. Painstakingly slow process, but required if you want the best image possible for the Elite. biggrin.gif
