    Got my 7200 yesterday :)

    Just finished watching a DVD and have noticed very mild screen burn at top and bottom. :eek: My problem is i dont want to stretch the films aspect with zoom so everything looks out of proportion, i'm using full mode, but the fillm aspects are'nt true 16:9 so you still get the letterbox effect, 1.35:1 or whatever it is.

    The Hitachi has a white screen thing which seemed to get rid of the marks after a few seconds switched on, but i'm a little concerned of long term effects. I have contrast, brightness and everything else set to 0. I read they are less susceptible after 100 hours use.

    On the subject of my plasma, thought i'd get a new DVD player (pioneer 585a) because my old player only had s-vid and RGB, and it looks crap even through the funky QED component lead. Should progressive component look grainy and rough edged? the players going back because it hums all the time, but the picture's not as good as my 4 year old Aiwa through RGB. Dissapointed :(

    Don't worry about the after image, it will, as you've seen, go after a few seconds. It's not screen burn, just image retention.

    As an alternative to the white screen, just watch some full screen video which will do the same job. I've had the 5300 (which has the same panel as yours) for well over a year now and have no problems with screen burn.

    As for progressive, it shouldn't be grainy but, as the Hitachi is an ALIS panel and therefore interlaced, a progressive signal (IMHO after LOTS of testing) looks no better than an interlaced one.

    Thanks, feel less concerned now.

    So what DVD player would you recommend to gain an improvement? Should i stick with RGB?

    RGB through scart looks fine from my cheapy Skyworth DVD :smashin:
    But settings are critical.
    Don't forget that DVD input settings will be different to Sky etc.
    Contrast,brightness, colour, etc all different.
    I'd be amazed if you have it set up properly already.
    Keep playing with it, you'll get it sorted :smashin:

    What do you mean when you say RGB? do you mean RGB scart? RGBcvS? or when you say RGB do you mean 3 RCA connections coloured red green and blue? (this is Component YUV/YPbPr)

    I forgot.
    The AV1 input doesn't do RGB.
    Don't know if that helps at all :confused:

    RGBcvS is RGB composite video Sync (RGB scart) so you are using RGBcvS

    RGB requires a sync there are RGBHV RGBS RGBcvS RGsB so there are lots of types of RGB. so back to the original point component YUV aka YPbPr will most likely give you a better picture
