Samsung D7000 & D8000 Settings/Calibration Thread - Page 90

post #2671 of 3298
Hi,
Hope i'm in the right thread....i've got a big issue with my ps64d8000

this picture shows what happen when i turn on the screen....and of course it remains when there is a picture....more or less noticeable depending on what colours are used...
of course i called samsung but if someone has an idea of what can be that failure...
thanks.
post #2672 of 3298
Well, this is settings and calibration, neither of which could be causing what you show here. This is not something I have seen posted before. The usual troubleshooting steps should of course be followed - confirm all inputs affected, unplug the set for an hour or so and/or perform a factory reset - but beyond that, you probably need another service call. Did they give you a warranty with your last repair?
post #2673 of 3298
Thanks for your quick answer.
Yeah i've done all the troubleshooting testd....unsuccessfully...
And yes it's still under warranty...and i call the service...and i'm waiting for an apointment...
Well...sorry for having posted here...and thanks again.

No worries, there are usually more knowledgable folks frequenting this thread, so maybe you will eventually get more insight. Good luck.

Draft #2a released on 03/15/2012. Added more detail to grayscale and gamma calibration. Added new section on calibrating the color space.

Hello Larry, thanks for the excellent work and have recently purchased a probe i1d2 and begin to experiment with the calibration ....
You'd like to ask if the draft is complete or whether it needs to be completed.

Thanks again and sorry for my bad English.

That's going to likely require a panel replacement, nothing you can do on your end.

I have Time Warner cable. When I select 1080i as the source on the box the picture is very zoomed in. This just started happening. Ant thoughts on a solution? As far as I know I did nothing to my settings to make this start. I have everything adjusted to Larry's 2d set and Screen fit. When I change the cable bxc to 720p the zoom goes away. Thanks.
post #2678 of 3298
Make sure you are in screen fit mode when feeding it 1080i.

Roby,

In essence, it is finished with respect to the technical aspects. As it stands, it is quite usable as a guide. When I get the time and can get myself motivated, I plan to fix some minor typos, clarify some sentences, and add some closing thoughts. If anything is not clear enough, let me know and I'll attempt to fix it.

By the way, your English is fine.

Larry
post #2680 of 3298
Perfect!
Your guide to the calibration together "Grayscale & COLOUR CALIBRATION For Dummies" is a great thing for a beginner.
I always set my TV with simple disk tests (such as AVS HD) also obtained good results .... but the reading of your draft to me is opening a new world!

I would like to give Chad a big thank you for the fantastic job he did calibrating my D8000. Chad was here Monday and spent a total of 5 hours working on it a long with doing something's that he did not have to do for me. He arrived on time, was prepared to start and was very professional. You can deffinently tell that he knows what he is doing.
I am a DIY calibrator with my own meter and CalMan software. So as you can imagine I asked a lot of questions. Never once did I get the feeling that he was getting irritated with me for what I am sure were a lot of stupid simple questions. He answered them and tried to make sure I understood. Also I never felt like he was in a rush to get done and leave. Again he did some extra things that he did not have to do.
At the end of the day, all I can say is wow. I have tried many, many times to calibrate this tv but never got the picture to look this good. So if your looking for a pro calibrator this is the guy you want.
Thanks again Chad.

Here's what got me interested in this: We had two HR23-700 models -- one in the living room and the other in the bedroom. The living room unit died and was replaced with an HR24-500. The black level problem was immediately apparent. The colors looked fine. (This is an HDMI problem. Black levels using component connections are not affected.)

I did some extensive experimenting over the long weekend and determined that, for the Samsung, changing the HDMI Black level is detrimental to the gamma. Significantly reducing the Brightness, however, corrects the problem while maintaining the properly calibrated gamma. I used both my i1 LT and i1 Pro meters in order to measure both black level and colors accurately.

Just to define what I mean by "significantly reducing the Brightness": For my D7000 where originally the Brightness was set at 64, I had to drop it to down to 44.

There's more to come about the results of my experimenting but it's getting late this evening. So... to be continued.

Larry

I just wanted to bring this backup concerning the HR24-500. When Chad was here caling my D8000 I talked to him about how this model was putting out RGB rather then YPbCb like the rest of the directv boxes. So he did a test with my tv. He had just got done calibrating my tv, he set his pattern generator to RGB. We looked at the HDMI black level adjustment in the tv menu and it was not grayed out. We set it to low and he then ran his tests again. There was no difference in the results. So the conclusion is if u have a HR24-500 just set your HDMI black level to low and u will be good to go. He also mentioned that this was not the case for the C series, they deffinently had a problem with RGB.

FYI, that was in fact sorted out.

I also have TWC. I had a techinician working on another problem, but he warned me about the "#" button on the remote, which can zoom in the picture. He said he gets a lot of calls about that when someone presses it by accident. It may be worth a try to see if that is your problem. It is the button to the right of the 0 on the remote.

I have the 64d8000; have followed many calibrations settings but can't improve the black level, blacks are really dark. What setting should I adjust ?? Thanks

Brightness and/or gamma. Most people here like gamma at -2 with a brightness of around 56. Also make sure all the "enhancements"like black tone and dynamic contrast are disabled.

If you don't have a cal disk there is a built-in ramp for setting contrast and brightness under advanced settings»expert pattern»pattern 1.

This is a common complaint that can be due to a misconception about calibrating gamma using a power law fit. I will be updating my calibration settings (post #2) for the D8000 with an alternative that may help you out.

Seejeffrun's settings did wonders for my 51pnd7000! I couldn't find good settings for this size and model for the longest.
Thanks for your work Jeff

I have the same TV. So, I'll give it a try.

Thanks!
post #2690 of 3298
Just remember, the color and white balance calibrations for D7000s and D8000s definitely shouldn't swapped. Basic picture settings are best done by your own eye under typical viewing conditions using a simple test disc. Try the free AVS HD 709.

zoyd,

From your updated post #2 in this thread, it appears that you decreased overall gamma (-2 to -1) and then increased the mid/mid high gamma (reducing the 10 point interval values) and greatly decreased the very low gamma (increasing the 10 point values.)

Would you please post your resulting HCFR chc file for this method? I followed your postings over at the calibration forum and find the technique very intriguing.


Larry
post #2692 of 3298
sure, here ya go. disregard the color measurements but the gamma profile is what I'm currently using. I also had to reduce brightness so that levels 17 and 18 are clipped to get the 1-4% patterns to look right. I would be interested in your impressions, especially with film based material.

post #2693 of 3298
Thanks. That's about what I pictured. What I find interesting is that for film I do prefer a reduced gamma at the low end and increase somewhat the first two 10 point intervals -- even though I post my calibrations with a pretty flat gamma curve. (I don't want to hurt the feelings of some of the certified three day wonders.)

My wife, who has the critical eye in our family, insists on a lower than normal low-end gamma. I always will yield to her more sophisticated visual memory than mine. I'll have to play around with gamma more when I get the time. With my current 10 point settings, I think that I have sufficient room to come close to reproducing your curve.

I tried at -2 but had to go up to -1 to get it flat and in the right range. Sounds like you have a good consultant there!

I'm seeing some issues on my 51D8000 with the Chroma Alignment chapter of the Spears & Munsil Blu-ray disc.

Before I spend the time here describing the problem I'm seeing, I'd like to know if anybody else has that disc so we can see if the issue looks the same on anybody else's set.

I'm not sure if this is a "settings" issue or not, but what I am sure of is that in reading every post on this thread I am convinced that this is one of the smartest bunch of guys around.

It still could be a settings issue ...
post #2696 of 3298
zoyd,

I've reproduced your gamma curve exactly. I'll be viewing various movies over the next day or two for evaluation.

Have you actually read through the S&M tutorial on color space? Looks to be a tedious job to run through the checklist, but if you seriously want to pursue it, this should allow you to pinpoint the problem:

http://www.spearsandmunsil.com/artic...olorspace.html

These sorts of errors can be related to the source, display or a combination of both. I use 4:2:2 because Janos had apparently determined that to be optimal (at least for models below the D8000), and I am confident that my Oppo BDP-83 can output that correctly. I have the S&M disc, but haven't spent much time looking at these patterns.
post #2698 of 3298
Oh my gosh.... will somebody who is truly tech savvy PLEASE help me calibrate my new samsung pn59d8000. It is not an option for me to hire a professional. We watch a ton of hockey and watching the game last was like looking at dirty ice. I had it on Dynamic, as I couldn't stomach it on another setting. If I turned it brighter, it made the other channels look horrible. I thought it might be the NBC NHL feed, so I checked out my other tv... not so. It only has about 6 hours on the tv, so I am a little nervous about doing anything incorrectly. Every calibration I have read is with people using movie mode... Movie mode for me was just simply too dark. I'm begging somebody to help me get my ice white ...Thank you!
post #2699 of 3298
Well, the problem with that request is that there is no such thing as a "sports calibration" in the true sense of the word since "calibration" generally means you are conforming to a standard (you may want to read my last post about this, sorry for the condescending tone, but I was irked). You are looking for subjective settings, which are best left for you to decide.

If you use recommended settings in this thread then you are about as close to a true calibration as you can get without advanced equipment. Movie mode has nothing to do with the brightness, you can still jack that up as much as you like using the cell, brightness and contrast settings. If that still doesn't do it for you, then also try changing the color tone to standard or warm 1. If you still can't get what you want, I'm afraid you should have gone with an LCD. If you search around here a little bit, you will find that plasma seems to disappoint a lot of hockey fans.
post #2700 of 3298
Thank you Avid... I take no offense to any tone.. Trust me, I need all the help (obviously) that I can get. I'll search out your other post about this and then try the settings that you have. I've been an LCD person since they've come out and I've always had good luck. But, hockey is tough on almost any tv I think...thanks again for your help. I really appreciate it!
