    Default What is the difference between using "Prep-Slides" and "Breaking-in" the screen.


    Hi, this is my very first post and I would like to thank you in advance for answering it.
    I just purchased the TC-P50ST50 and was going over the D-Nice calibration settings.
    In it he mentioned that the 100hr prep-slide process is not meant to be used to break-in the screen.
    I am just curious as to what the difference is in terms of the process and overall result.

    The processes are essentially the same, but D-Nice's slides have a somewhat different purpose.

    The phosphors in a plasma TV are generally more susceptible to change during the first 100-150+ hours of use. So the similarities between D-Nice's prep and the break-in process you see some people follow, is that you run a specific order of colored slides to evenly/uniformly age all of the phosphors when they're more susceptible to change. D-Nice also does it so that others can age their panels the same way he aged his reference panel for optimal results when you plug his settings in. Because as you may know, plugging in calibration settings is rarely perfect due to panel to panel variations.

    Now the whole 'break in' procedure is still up for debate. Some people feel that it is essential to run the slides during the first 100-150hrs of use, as it reduces or eliminates the chances of Image Retention etc., but I'm personally on the side of thinking that it's just BS. Resistance to IR varies from panel to panel, model to model. IMHO, there's nothing that you can do to reduce the chances of IR, outside of keeping the contrast lower and mixing up your viewing content a little, avoiding stationary logos for long periods of time. There have been so many cases of people not running the slides and have no IR issues whatsoever (like myself), and others running the slides and getting IR, or even burn in problems.

    I do feel that there is some benefit in running the slides, even if you're not using D-Nice's settings, to evenly age the phosphors. But personally, during the first 100-150hrs of use, I would just avoid black bars as much as possible. Not worth the time IMO.

    its the same the 100 hour break in is to age the panel evenley. i ran slides for 200 hours.
    because my room was not ready for the tv to go in to so i just ran them for 200 hours.
    it does help tv looks nice on my tv and blu-rays are stunning

    Other than enhancing the likelihood that your panel might look better by applying D'Nice's settings AFTER running his break-in (or Prep...) slides, I also see no "magic" in them.

    However, I do think it makes sense to Purposefully Age a new panel, particularly during your Return Period, even if only in the hopes of uncovering any Infant Mortality issues.

    Personal preference is to avoid Bright Static Images and keep Letterbox Bars (especially Vertical ones) to a minimum for the first 150 - 250 hours.
    Note: "to a minimum", NOT "Avoid Completely!"

    We'll run a letterboxed DVD within a few days after receiving a new panel -and full-screen, "no logo" programming from the first day.

    Like to use slides, from a SD Card, to "Age" the panel during what would otherwise be "down time," as they are relatively safe: No DVD player to fail, disk to Skip, or STB to decide it is time to turn itself off! (As our Uverse boxes do after enough time with no input.)

    FWIW - being a Limited Sample Size - all three of our Panasonic plasma sets were at least Somewhat More Prone to IR early in their lives than later.
    Our newest - a 60ST50 - was VERY prone to Quick Onset IR up until some point past the 400 hour mark. Currently, it still seems slightly more prone to IR than the older panels, although Onset Time has lengthened, Visibility has Lessened, and Duration is now distinctly shorter - all steps in the right direction, and I no longer consider IR to be a Concern, at least given normal usage.

    Disclaimer: We do NOT use the set for Gaming, nor as a Super Large Computer Monitor.
