    I ran my Panasonic 50THPX600 in for about 200 hours, cinema 20%con/20%brightness.

    Yesterday I played for a couple of hours on my XBOX360 and afterwards I noticed the image of some games interface was ghosted/retention. You only notice the retention from smaller distance or when looking for it, but its still there very firmly.

    I run on the following settings:

    Normal
    Contrast: 75%
    Brightness: 25%
    Sharpness: 75% (default is 50%, I like sharp graphics)
    Color: 65%

    Questions:

    • Does sharpness have any effect on burn-in/retention propability ?
    • Is this to be expected ? Couple of hours gaming and voila image retention ?
    • Can I fix it? An hour normal video playback solves it ?
    • Could it be that I need to run the screen in some more or play at lower settings then mine above ?

    Any input is appreciated,
    Greetings,
    Marc

    Hi marc
    Its good you took it out of dynamic mode Cinema is best, those settings seem to be a bit odd from my experince too much contrast and very low brightness and lots of colour. as for sharpness how are you connected to the screen for consoles?

    Thanks for the reply,
    The settings are a bit odd, though its worth noting that I use only those setting to game on my console. I would not use these settings for realistic movie playback or anything.
    The console is connected with components cable.

    When I adjust the sharpness naturally everything gets sharper thus fixed interface windows like game health monitors brigthen a little bit up, so my guess so far war that I used exessive shapeness setting resulting in easy or fast ghosting/image retention. But that is a wild guess.

    ps: Oh and my screen is installed in a very dark place, so no much need for brightness, also I always tend to favor a darker picture then (overly) bright.

    Yes Ashroh, naughty boy!

    How dare you not calibrate your console using DVE before using your plasma. Panasonic plasmas are burn-proof don't you know - it must be your fault, obviously. :rolleyes:

    Seriously:

    Brightness does not raise the light output, that's contrast. It should be at 50% or slightly higher to see most shadow detail, although black level on anything with a pic less than half a blank screen starts to rise above 30% on Panasonics. People setting their brightness on Panny screens with a blank screen thinking 'ah, black level isn't getting higher until 70%' are sadly mistaken.

    Contrast will depend on your console - 75% isn't too high for most people for most sources.

    Sharpness shouldn't do anything for the risk of screen burn

    I think colour may be the culprit - 65% on a PX600 is probably in the very high category...
