    I have an In-Focus Screenplay 5700 projector connected to a Denon AVR-2805 AV amplifier using Component Video connections.
    There are two sources connected into the Denon, a set-top box connected as composite video and a DVD player connected as Component.
    The amp up converts the composite input to component to feed the projector.

    When viewing either source via the amp on the projector an effect similar to 'posterisation' is seen on various parts of the image, but most noticeably on fleshtones.

    Both the projector and the amp are about 6 weeks old and the effect was not evident until about 2 weeks ago.

    The common components seem to be the amp, cable and projector so, anyone have any ideas on what might be the cause of the problem? Thanks :)

    Some projectors can show this effect - I think it's sometimes called 'clay face', and it can be a bit-depth problem or colour wheel index issue.

    If the amp is upconverting, then the colour bit-depth may be getting reduced, so I would try those scenes again, but connect the player straight to the projector and by-pass the amp. That would at least eliminate the amp from the equation.

    Thanks Gary, 'Clay face' is an excellent description of the effect!

    I'll give the direct connection a go, although the DVD is connected via component into the amp, and on to the PJ, so no upconverting on that source.

    Try it anyway and see what happens.

    Do you have another DVD player to try?

    I've got a cheap and cheerful Sony somewhere, but not sure if it's got component out (can't remember what model at the moment!).

    But surely if I'm getting the same effect with the set-top box source it won't be the DVD?

    I agree, that's why I suspected the amp, but it doesn't hurt to try things just as a check.

    What specific scenes do you see it in?

    Gary.

    It seems to evident on everything - especially for example on newsreaders faces on the set-top box and any scene from the DVD with fleshtones.
    I'll try the swap out later in the week (am away at the moment) and see if I can narrow it down at all.
