Samsung D7000 & D8000 Settings/Calibration Thread - Page 78

Jeff, a small addition to Larry's notes in case you didn't know. Step e will generate target Y values to achieve your target gamma in the HCFR table window. Use these values during step f to adjust your luminance at each step.

Thanks, zoyd. I'll add those additional HCFR specific points. But I'll wait a while to see if there are any other contributions.

Because of the large number of members that have been buying meters, I've been toying with the idea of putting together these notes to help them climb the learning curve. This afternoon seemed to be the right time for me. If anyone has additions, corrections, clarifications, or general comments, please let me know and I'll get them incorporated.

Larry

Great idea, Samsung specific workflow FAQ would be handy.

hey guys,i wonder if anyone with knowledge of calibration can have a look at my calreport from the geek squad. im going to have to email it to you because the file is too large to upload in this post. please reply. btw,its a pn64d8k.

ok,sorry for the way i did this,but this is my calreport.

cont....

please help. this looks wrong to me.

I am not an expert on calibration. But I did spend 5 hours this last Friday asking questions and learning from a 10 year pro.

This is my post calibration report on my d7000. My amateur reading of your reports, I'd say it is possible to get more accuracy.

Hey guys just got my TV calibrated by
Gregg Loewen -President, Lion Audio Video Consultants Inc.
Lead THX Video Standards Instructor
Highly recommend him. My viewing area is very dark he told me to put black trash bags on the window and had all the lights turn off. My room is 12x13 with no sun light or any other light coming from any where. If you have a lot of light coming from anywhere try the same settings but change the Gamma +1 or +2 what ever looks better to you.

Cant upload the primary/secondary Chromaticity page because is to big to upload it but trust me when i tell you they are perfect.
PS: english is my second language so if I write anything wrong bare with me LOL

can you tell me which one shows my MLL?

It's not shown in the pages that you posted. It would be under a 0% luminance heading and your data only goes down to 20%. This is not unusual for a report by the way.

Hi all..new to the forums and picked up a D7000 a few days ago. I've been reading this thread, using some suggested calibrations, and also tried adjusting on my own, but I'm having one issue. The reds, yellows, greens, and blues seem to stand out more than any other color. What settings do I need to adjust to tone these down? Or...if there is a set up that I missed, that will fix this, I would appreciate being pointed in the right direction. Thanks in advance.

gotcha,i find it weird though that he was having trouble getting my greyscale and colors "correct",i thought these tvs were supposed to be easy to calibrate? also he settled on "cool" being more accurate than warm1 or 2. he unlocked the cal day/night mode and only used day.

im having a recheck on this job as the brightness seems waaay to high(blacks seem more grey,picture looks washed out) but if i dont get satisfactory results,i hope theres a factory reset that i can do which will reset his sm adjustments. will report back tomorrow after he leaves.

bsc,

We need more information to help you out. Do you mean the colors are too bright? Too saturated? Give us some viewing examples where it is apparent.



Eddie,

There is no need to go into the service menu to reset anything. Just note all the settings that were made. Use Elvin's post above as a template.

One thing that I would suggest is to change the Gamma setting from -2 to -1 or even zero and see if that helps. The calibrator adjusted the TV to display with a gamma of 1.96. What you want is more like 2.2 which you will get with the Gamma control set at zero.


Larry

Yes play around with the gamma if you have a dark room put the Gamma to -1 if you have a light source or find it to dark try Gamma 0 or +1

yeah the colors look way too bright,gives a screen door effect. green seems to be exaggerated it kinda "pushes" green from places it shouldnt be(black slacks,facial hair,anything blue). also brightness in general seems to be way too high,kinda like he tried to turn my plasma into a 10 year old lcd monitor.

i tried to set the gamma as you instructed but the cal day setting "greys" everything out except picture options like "digital noise filter" "mpeg noise filter" and "film mode",im unable to access this control it seems he locked me out from tweaking anything but post processing stuff in the normal picture options menu.

overall the color issue doesnt bother me as much as the black level. the blacks are more greenish grey. with color i wish i could fix it myself but his sm adjustments seems to have affected the other picture modes as well.

which is why i was wondering if i could have him just factory reset those sm adjustments. (the original values were not recorded for reference)

thank you for being so helpful

Eddie,

Do not enter the service mode. At your level I would recommend against it. The calibrator locked the CAL modes and that is why the controls are not available. Use the Movie mode to adjust the TV to suit your preferences. Please do not go into the service menu at this time. When you have a bit more experience, you can unlock the CAL modes by making a simple change in the service menu.

From the calibration report, it is not surprising that the near blacks have a green/blue tint.

Why not call the calibrator back to redo the job? Until then, use the Movie mode.


EDIT: I have to correct a statement that I made a few posts ago. What you want to do, if you could, is reduce the Gamma setting not increase it. But you only have one click remaining since it can only go down to -3. It's all moot anyway since the controls for the CAL mode are locked.



Larry

i appreciate all your advice and input larry! yes i am having a return service call to have them fix these issues(fast service btw,they scheduled me for tomorrow 12-4pm) ill stay away from the sm myself.

heres hoping tomorrow yields better results,lol.

Two pieces of advice:

1. Forget about BB, you're wasting your time and money.

2. Reset everything, read a bunch here, think carefully about all the cals that have been posted, and go to work.

My reason for 1 - I have a skill-set that would be similar to a good calibrator but in another filed. A national company decided to offer a service a few years ago that meant training people to do what I do. The skill level of their people is a joke (I played spy a few times to find out.) The primary reason for the low skill was the limited training they received. I should add that clients seemed pleased ... when you don't know anything, it's easy to be impressed if you're the trusting sort

My reason for 2 - That's what I did (before paying for a real calibration) and my results (D7000) in a few areas, using nothing but my eye, some discs and combining a few cals here (after testing many more) were better than your posted "after." That's pretty frigging scary.

That all looks great except I have a question. At that contrast/cell light level I would be concerned about eyestrain in a dark room. What was the 100% stimulus readings? At those settings it should be >40 ftL which would be more typical for a bright environment. For example I have my D8000 running at Contrast 95 Cell 13 (35 ftL) gamma -2 Day, Contrast 95 Cell 9 (28 ftL) gamma -3 Night

I'd be interested to know why he chose a target gamma of 2. That seems to be well outside the common preferences. Looks more professional than other Geek Squad calibrations I've read about (some of which are truly embarassing), but the end result still wasn't too impressive.

If I do a factory reset will it reset his service menu adjustments to my gains and drives in the Sm?

No, that's the nice thing about the cal modes - they stay set no matter what you do. But no need to worry about returning your TV to factory defaults. The calibration simply makes use of the advanced controls, all of which are easily reset to default (once you have unlocked the picture mode).

the reason i ask because even in the movie,standard and relax modes there is a green problem,as a result of his sm adjustments...

i had the geek squad come out and even they were disgusted and said the job was terrible so they called the head honcho gs calibrator guy who apparently has 10 years exp to see if he can fix it.

when i told them he calibrated using the "cool" color temp they scoffed!

The calibration should have no effect on the standard modes - you should be able to check and reset them if necessary (color space should be auto, white balance should all = 25, 10pt should be off).

The only things he should have done in the SM are enabling and locking the CAL mode. If he made changes to the ADC section of the SM, then you might have a problem. Generally speaking, there is absolutely no reason to change the SM gains or offsets. All the necessary adjustments for a full calibration are available in the Picture>Advanced Settings menu.

yep,he made changes in my sm gains and offsets. before he did,he goes"man your tv loves green"

Well if that's the case, then the original settings could be lost forever. That would be a truly monumental case of BB incompetence. At minimum I would insist they calibrate every single picture mode.

Some VERY experienced folks here have deliberately redone the calibration at the factory level, but to do so without screwing up the standard picture modes is no simple task from what I've read. I think it requires an RS-232 connection to access the TDM (top debug menu).

here is my opinion of what i should do. im going to have this new guy calibrate every picture mode and wont let him leave until im happy with everything.

if it ends up being that i dont like them,im gonna scream at best buy and hopefully get an exchange set.(even though its past the return date)

i paid alot of money for this tv and ill be damned if i have to just deal with these results.

From the gamma table shown in his 123.pdf attachment, the Y magnitude at 90% is 108 cd/m^2. At 100% it should be about 22% higher for a gamma of 2.4 which would make the peak approximately 38 ftL or so. It does seem a bit strange.
