My mistake was to post in the wrong section, though I am glad now that I did because I am learning so much.

As far as the settings I currently have. I wasn't even going to bother with it as I will be swapping this set out with the 632U model, but after searching and finding very little info out there on the 630U model, I thought I would run through and do what I could and post the settings for someone stuck in a similar situation as I was. Just trying to be helpful, not meant to ruffle any feathers whatsoever.

yeah my response is a bit late, though I still wanted to reply to your initial post


good to hear that you're learning quite a bit here, that what's this forum is for

I am a little confused though as George makes pro calibration sound like an absolute certainty, however the more I'm reading I'm learning that there are various numbers of ways to calibrate, with various different tools and various different control sets. So, in conclusion, and please correct me if I am wrong, but Pro Calibration is in, by no means, an exact science and in the end comes down to the Pro doing the Calibrating and what they feel is the best tool, control set and numbers to use?

In fact, I could probably have 2 different guys come in here at 2 different times and produce 2 very different results on the same set, correct?


You are right in that two different calibrators would likely come up with two different numerical values for your settings. Would you be able to tell the difference visually? Not likely unless one was far off and performed with a meter, equipment, and/or software that was off in some way. Or the person doing it was not familiar with your TV or not experienced enough in how to do it and/or just did not care.

On your other observation. . . I agree. I've tried many times to communicate that things do not always come across very congenial in this thread and it doesn't encourage. You shouldn't have to be made to feel you are intimidated or attacked. . . or implied that you are a troll.

Good luck on you new TV!

If it was not meant as such and I don't think it was, please explain how and why 2 professionals with equal skill sets and equipment, working on the same set, in the same environment would come up with substantial different settings.

The Rec 709 Standard an exact science but consumer sets are not perfect and many times they can not reproduce the 709 standard perfectly. This is where the experience of the real pro comes into play. They have the knowledge to know what compromises will be lease noticeable to the human eye and how to work around manufacture limitation.

Just like all service providers, all pros are not equal and it is up to the consumer to figure out which one is the good one..

The differences that would likely result would be beyond human perception for things like D65 white point and Rec. 709 gamut. Variations in gamma and peak white (aka light output) would be far more common, since there is no one correct standard/value for those parameters, only recommended ranges that are pretty loose. Another area where variation may occur is setting contrast/white-level, where each calibrator may have different viewpoints regarding WTW content and where to clip, if at all.

Right. . . as I said, they would likely be numerically different but probably not able to tell the difference visually unless something was wonky.

All of the best calibrators have had many experiences where we have to go after another calibrator and undo the mess that the original calibrator made.
Calibration is a mixture of science and art. There are always judgement calls that highly influence the outcome of the set. I have to agree with the original claim.

So true! I still recall the significant improvements and corrections you had to make as a result of that local dude I had out on my Sony CRT RPTV way back in the day. At the time, I remember him telling me he was trying to reduce red color saturation push via grayscale among other things.
