    I got a Panasonic 37PW7 last weekend and have one question.

    When I am watching non widecreen material, I prefer to use the 4:3 mode on the screen.

    What are the dangers of screenburn on a plasma doing this.

    The user manual says to avoid using 4:3 mode for extended periods of time. How long do they regard as long periods of time, 1 hour, 6 hours, 24 hours.

    I hope some of you technical whizzes can help.

    Thanks

    As an educated guess, I would imagine that this advice is due to the possibility of different areas of the screen ageing at different rates.

    If you use 4:3 mode a lot of the time, those areas of the screen that are unused in 4:3 mode will not get the same workout as the active areas, which (in time) could result in the two areas giving different results with the same input.

    For example, if use causes the elements to gradually dim over time, the non 4:3 areas would remain bright while the 4:3 areas would gradually become dimmer, which would mean that when viewing a 16:9 signal there would be a clear distinction between the 4:3 area and the rest.

    At a guess anyway.

    don't if its the same on all pannys but on the 42pw7 (in screen saver options)you can set the side panels when viewing 4:3 to bright to reduce the risk of burn....i think the brightness changes whilst in use.

    I've had my 42PWD6 for about 18 months now and watched a lot :blush: of Big Brother in 4:3 without any signs of screen burn.

    Cheers,
    Liam

    Thanks for the info.

    I will try 4:3 with the screensaver option on.

    Could screenburn also be an issue when watching films with a 2.35:1 ascpect ratio?
