Here's the original question:
On a 2009 Plasma TV, is there any value in doing a break-in if you don't intend to apply any "offsets" or any other settings from someone else's TV in general?
In either case, how long should you wait before during a full (meter) calibration to make sure it "sticks"?
My view is that if you plan on having it professionally calibrated at some point in the future, say...2 to 3 months, you can probably just watch normally and it'll "break in" on its own that way. Using the DVD just speeds up that process. It's been shown (I can't find the article right now, maybe someone can help) that the color temperature changes and settle during the first 200 hours. If I remember correctly, what they did was take measurements at specific intervals during the first 200 hours of running slides similar with Evangelo's DVD and the color temp decreased over time. I believe it was over 100K. Some might say that's a small figure, some might notice the difference. This is the AVS forum after all, and some of us are likely enthusiasts, which means we want our equipment to perform at its maximum potential.
Will the slides prevent burn in? I don't know. D-Nice doesn't seem to claim that it does. I assume that it is to help bring the plasma to a semi steady state so you can use his post break-in settings. In addition, I think that's the way he did it. Someone on the forum who used the procedure prior to having D-Nice come and calibrate his Pioneer found that the break-in + post break-in settings brought his plasma to 6500K. Now, he obviously didn't do any measurements prior to breaking it in, but I doubt it was at 6500K.
In addition, people who tried using D-Nice's post 150hr break-in PURE settings PRIOR to the 150hours found the picture a bit odd, but they looked great if you apply them AFTER breaking it in per recommendation. So yes, there is a difference.
Personally, I wish I could have D-Nice calibrated my newly bought KRP-500M this weekend or the next, but I don't know if I can, so I'm doing my best to replicated his settings.
However, in the end, it's to each his own. Cheers!
