    Hi,

    I'm very happy with this machine, thanks to all the reviewers on this forum for helping me to choose :)

    I have noticed a setting for 'comb filter' in the setup menu, I tried setting it but couldn't notice any difference - I have the EH60D connected by RGB scart - should the comb filter improve things ?

    Thanks

    Ian

    I think the comb filter may only work on a composite signal.

    Casting my mind back to the days of laserdisc....the digital comb filters would only work on the composite outputs and not the s-video outputs. I suspect this is the same on the EH60D but may work on input as well as output.

    Does the manual offer any further detailed info?

    The manual says that with it enabled 'the picture becomes clear and contour rich' and to turn it off if the picture is grainy.

    I can't see any difference through RGB or Component so you might be right.

    cheers

    Hi

    The 3D Comb filter only applies to inputs and a composite signal, i.e. the internal analogue tuner or some video connected via composite using the yellow video-in plug or via a SCART lead that is using a composite signal. The filter is what separates the colour and luminance information, in S-Video or RGB inputs this is already separated so bypasses the filter.

    You will not see a difference when playing a disc and switching the filter on and off as the comb filter isn't needed for data of the disc.

    Regards

    Philip

    The claimed advantage of a comb filter is to reduce 'dot crawl' on composite signals, particularly on the red colour.

    As PhilipL says, using RGB or S-Video achieves the same thing.
