Samsung D7000 & D8000 Settings/Calibration Thread - Page 92

Hello , Avid, my delta E's were below 3 across the board . I have the data with me at home on my laptop (i am typing from work )lunch time I have used an ID2 to calibrate my tv with. In the end with the color down to zero just to check for tinting I can clearly see it's reddish, not very neutral, it's visible in a 10 step Grey pattern too. My final numbers end up with a blue drive of 43. The meter was reading blue at around 85 % in the mid to upper end or the Grey scale prior to the calibration. I am highly suspect full that it is giving me incorrect values. I no longer have the meter the cord on it ripped, kapootcky, no more meter. Looking at getting a D3 Pro with Chromapure.

Yeah, it's not the most reliable instrument of course, but for beginners just looking to get their feet wet I think it is (was?) worth the price. Now that they've stopped making them, I guess it's probably becoming a more risky purchase, but they were known to be fairly reliable prior to that. I think Larry has found mostly red drift on his i1D2 as it has aged. I store mine in a jar with dessicant since moisture is a killer for the color filters it uses and so far I don't detect any major problems by eye. I'm sure I'll be looking to upgrade eventually, but I'm putting it off as long as possible.

So maybe I should say - do not buy a used i1D2 unless you know it has been properly cared for (or even better, checked for accuracy). New ones are probably still ok, but there may be some chance of getting a lemon at this point.

@Larry, you'll be pleased to know that your empirically derived gamma function is very similar in shape to what BT.1886 recommends for a display with your black/white setpoints.

So I noticed just before coming over here. I guess my consultant deserves some praise.

Larry

Zoyd, could you post your .chc file for the BT. 1886 calibration you did and posted the settings for in your first post?

Here it is.

Thanks.

Hmmmm ... so that gamma curve is basically the opposite of dynamic contrast. Have you defeated what you previously called the undefeatable dynamic contrast? You make low IRE lighter and high IRE darker. I can't figure out how you end up with such a high contrast ratio. Must be your "better blacks" tweaks.

Now, about that CIE ... wtf? Your points are waaay off.

-That file was just used for gamma adjustment, ignore the color measurements (and white balance).

-The contrast ratio reported is 100%/0%=120/.027= ~4500. ANSI contrast is the same but static contrast at high APL is closer to 2500. I have had the mll tweaked as low as 0.02 cd/m^2 but backed off a bit due to misfiring.

There is nothing you can do about inherent dynamic contrast., low APL has a lower gamma than high APL. I calibrated with standard window patterns so that curve reflects the low APL gamma.

Has anyone installed the new firmware update for the D7000 series? It is version 1016.2 dated May 10. The description is "makes TV available for 3D explore and new MLB TV. This firmware improves picture quality on SD pictures."

Larry

I installed it two days ago on my 64D7000 (which has a successful FBr logic board fix) and have seen exactly zero changes. I haven't checked out the smart hub though.

Quick question: is the gamma setting an 'acceptable' tool when setting brightness and contrast? I can get the two first patterns on the AVS HD DVD completely right with a gamma of 1. If I keep gamma on 0 I have to make a compromise between the two patterns. FYI, here are my ideal settings (found with the basic patterns on AVS HD):

Cell 20
Contrast 67
Brightness 59
Sharpness 5 (this could be 10 or 20 too, I just can't tell a difference)
Color 51
Tint 51/49
Gamma +1
Everything else on the defaults of Movie mode or off.

Willie,

Thanks. I installed 1016.2 late last night and also see no change in HD picture quality. SD, however, is noticeably improved. There are a few additions to the smart hub apps.


The Gamma control does indeed affect the overall brightness of the picture. A setting of +1 on a D7000 is typical for obtaining a gamma value of 2.2 to 2.3.

Your setting that you posted are fine for a peak white output of about 30 ftL. That level is where my eyes are most comfortable and where my 64D7000 is calibrated.

The Sharpness control for this model seems to be best at or below 20. I have mine at 20 when watching with the Directv box and at 10 when watching a BD or DVD.

I have a question regarding screen fit and fios stb.
The stb is output to 1080i and samsung plasma is set to screen fit.
For some content, on the top I see a less than 1/2 inch black bar gap from picture. I wonder if others have seen this as well with content.

My concern is will it cause burn in or IR and I guess there is no work-around as 16 9 mode is not true pixel mapping.

No problem on your end it seems, those would be the optimal settings. Personally, I wouldn't worry about this sort of burn if you're watching a good mix of content. Now if you have a panel that happens to be more prone to IR, maybe it's something to keep an eye on, but I haven't seen many (any?) complaints of black bar burn.

What content? Does this happen with a BD input? Are there adjustments on the stb?

I believe your specific problem is the first that I have heard of.

Larry

This issue happens specifically with cable content. I have not seen it with blu-ray. My stb is setup to 16 9 1080i.
The only adjustments are setting native resolution and tv aspect. As per picture it is either zoom or normal. Zoom looks distorted and normal seems to be what works with 1080 i. Funnily when I set the d7000 to 16 9 everything looks good.
My d7000 is set to screen fit currently.

Since it doesn't happen with a BD input, we can rule out a problem with the TV.

When you say "issue happens specifically with cable content," what do you mean? Does it happen with both SD and HD content? What happens when you let the stb format the picture automatically? In other words, not force it to output 16:9 1080i and let it use the station's original format.

It only happens on hd content and not on sd. With HD content it is with some stations and not all stations i.e hbo hd and max hd, you can see a horizontal black bar on top. The stb does not give the option to automatically choose native resolution. Only 1080i or 720P. I know with dtv there is an option for native resolution depending on station but on for fios.

Vanla,

Which specific stb do you have -- dvr? Motorola or Cisco? Model number?

Larry

Motorolla qip 7232 2

I see the same thing with my 64d8000 using directv. Only on some hd channels. Animal planet hd,showtime and a few others. I tried adjusting the position of screen fit but it just created a bar on bottom as well.

I've seen it on DirectTV as well (even OTA on occasion), it's clearly a problem with the content providers. It is odd that HD content isn't consistently delivered in a standard format.

Avidhiker and ipoop2much,
Thank you for the verification.

Thought I was going crazy!!!

Content is always an issue

does the new 1016.2 update have any negative effect on sets that had previously (and succesfully) applied the brightness fluctuation fix ? In my case i was sent the proper firmware from Samsung (I'm running 1014.6 on my 59D7000) and it did go through the proper optimization process. I don't want to apply the new firmware if it will mess this up as i almost never watch anything in standard def. thanks in advance

SouthFl1983,

Welcome. Update version 1016.2 does not effect the logic update. This was discussed about 13 or 14 posts ago.

Larry

im sorry, i just re read the past few pages of posts and didnt see much discussion on the issue, other than you and willie had both completed it and it didnt mess up your settings...after applying the update how do i confirm the logic update stayed the same and the brightness fluctuations wont come back...also will any other settings get messed up when upgrading to this firmware? thanks again, and sorry for my lack of knowledge on this issue

SouthFl1983,

Press mute+7+3+7+enter. (It may require that the TV be turned off and then on after a few seconds before applying the code sequence.) The logic version will be listed. To exit, turn off the TV.

WRT the fluctuating brightness: I guess you'll just have to take our word that they do not come back after the new update.

Larry

Before applying the logic board fix a couple of months ago I had highly noticeable brightness pops. The issue is still very much gone, also after updating to 1016.2. I've watched quite a few BDs since updating last week and would definitely have spotted any changes.

Just remember that the FBr effect can creep back and become noticable once again because, in fact, it hasn't been completely eliminated for everyone. Plenty of people have reported pops after applying the logic upgrade, so it seems some people's sensitivity to them may adapt a bit and start picking them up again (even though they're clearly much smaller). As for other settings being affected, this has never been confirmed for any firmware on any North American D series set AFAIK.

That said, if you are so worried about this firmware, maybe you should be patient and wait a month or so for more feedback. It's not even a week old yet!

Hiker,

This firmware update does not contain any files that would have anything to do with the logic.

Where did you find posts about fluctuating brightness that "creep back" on non North American D models? I never saw any mention of it on avforums but maybe I missed it.

Also, some people see things that do not exist and there are too many of those people in the world.

Larry

Hi Larry,

I am well aware of that and I think my post makes that clear. However, myself and others have seen pops post "fix" (sorry, I don't have time to find those posts, but most are brief mentions in the FBr fix thread from some time ago). Actually, I have found these "residual pops" increasingly noticable over time since installing 1014.6 (confirmed update). My impression is that there are others that have shared my experience (which I attribute to a preference for a high peak white and possibly a gradually increased sensitivity to FBr). Overall, I am experiencing far fewer instances of noticable pops, but they do persist (stepwise changes, just smaller in magnitude than before).

I know it may sound silly, but I can assure you they are real on my display but almost entirely limited to letter/pillarbox bars (which was not the case before the fix, when I could find them even in 16:9 content).
