    Can having my contrast too high damage my RPTV? I heard this from somewhere and i was wondering what the contrast level should be at. I currently have the contrast on 40 and brightness on 75. Is this ok? Thanks.

    This is probably the most comprehensive RPTV site on the web.

    Wouldn't high contrast cause video noise?

    >>> Can having my contrast too high damage my RPTV?
    Yes, definitely and quickly. Heat as well as light is generated as the phosphors on the CRT faces are excited by the electron beams, and the phosphor coating and the glue holding it on the back of the glass are literally cooked.
    When you bring your TV home and turn it on for the first time, before you connect your DVD player and antenna, turn the contrast way down. Turn it down to a third for RPTV or FPTV, down to a half for direct view.
    You can still complete your tweaking using AVAI or Video Essentials with the contrast limited as suggedted above. If you absolutely positively cannot live with the contrast that low, you can go higher but then the chances are greater of station logos or the MUTE/channel number legends being permanently visible as shadows sooner.
    In addition, with contrast lower, circuits are not maxed out as much or as often and they too last longer on average.
    Higher contrast won't cause video noise but may accentuate snow or noise already there.
