Default Panasonic VT25 break in?

I have a Panasonic 58 inch VT25 coming on Friday.

Is there anything special I should do to break it in?

Should I break it in before I use the 3d functions on it?

Thanks
David

I broke my VT25 in the following way:

Use THX mode with Contrast dialed down to 50 only viewing mixed full-screen content (no black bars) for first 100 hours.

Excellent choice btw.

Thumbs up Break-in

Yes, that is an excellent break-in method. I did the same thing myself. Of course, right after break-in, I used my DVE BD disc to calibrate mine, though in THX mode it only needed at touch here and there to perfect it for my living room.

By all means avoid watching a static image during the break in period most of the newer Panny sets are very good at not retaining Ghost images, but why chance it during the crucial breakin period so avoid picture with fixed identification images or scrolling news bars, to be on the safe side and then enjoy the VT25's are and excellent set with some of the Pioneer technologies built in.

I use the break in slides on a SD card, and just let it slideshow for 5 days. THX mode is another good one, and low contrast and full screen is fine too.

Where could I download these break-in slides from?

Just put the images on the SD card, pop in the side, and follow D-Nice's instructions.

If you do break in your VT25 this way, then you could try D-Nice's settings instead of using a calibration disc....

The thing I like about breaking in with the slides and NO television, is that all pixels are aged equally. When calibrating the tv with a meter, it would mean the space you are reading, is giving the same result as the rest of the screen, which should make for the best results. If you break it in unevenly, then the portion of the screen you read could require different grayscale adjustment than other parts of the tv need. Could be an uneven grayscale over the course of the screen. Im sure thats a stretch, but it seems possible.

Thanks guys. Not sure sure about using the sd card break in procedure. Call me selfish but I want to watch the thing when I bring it home

I'll make sure I tone the contrast down to 50 in THX mode.

Its' fine too. What the break in really does, is allows the pixels to mature at the same rate, thru their breaking in period. This makes them as consistent as possible across the whole screen. For calibrations sake, when you shoot the meter at the center of the screen, and make adjustments, the adjustments equal what the outer pixels need too. If you break them in with TV viewing, pixels may age differently than others. I dont consider this necessary, but Ive done the procedure before and am anal, so Ill continue to do it. I guess the 100 hour mark is generally what it takes these pixels to get to maturity, but Panasonic doesnt even mention break in anymore in the manual (IIRC).

You generally also see an increase in PQ as they age.

Setting the Contrast to 50 in THX mode for 100 hours also allows the phosphors to age.

Really the only reason to use somebody else's break-in slides is if you just have to use their settings for some reason...

Thats not true at all. There are several versions of break in slides but they do the same thing. Dnice says that using the slides allows for the best result from his calibrated points. This is ONLY true because it ages all the cells equally. When you break it in with tv content, they DO NOT age the same, because the screen is inconsistent in what it displays. Breaking in with THX is fine too, but the slides are the only way to equally age the whole panel.

Like I said, it allows for a more consistent calibration, but for most that does not even matter. When someone is using a meter that only hits a 1"by1" section of the screen, and thats what you adjust the whole screen too, you want to make sure that 1x1 section is equal to the rest. Thats all.

A professional calibrator explained this to me, and D-Nice himself confirmed it for me over at the AVS forums (sorry, I can't find the post).

The reason that people use D-Nice's slides is so that they can use his settings.

The ultimate optimal settings for a plasma depend on how it was broken in. People use the slides so that they can use D-Nice's settings. Their phosphors aged the same way his did.

For people who prefer using a calibration disc, any reasonable break-in procedure will suffice.

Slides do not age your phosphors "better" than any other method.

If this were true, and eventual PQ were affected by break-in, than manufacturers would break-in the sets in the factory.

I think we are close to making the same point. Plainly, I pay to have mine calibrated, so I want to make sure the screen is uniformly broken in
