    you should really set it up using a calibration DVD (as a minimum)

    this will allow you to set correct contrast and brighness and colour balance

    as a rule of thumb - I always had contrast on 50% for dvd and 55 for tv (source depending) and brightness no more than 50% in a dark room

    in a pitch black room, you can adjust the brightness up from 20% until the black background (ideally the black border on widescreen film) begins to go grey...then back down a few percent. This should be around 45 to 50% (again depending on source) and is a very non scientific way of max brightness before blacks go grey.


    also, make sure your lamp is set to film / cinema mode, this reduces the output and will lengthen the lamp life. :smashin:

    Hi avo,

    The lamp output doesn't change with brightness and contrast, only the way the mirrors dither to represent those levels. The only setting that will have an effect on your lamp is having it in low or eco mode, and so will make it last longer.

    Switching on has an effect on the lamp as it has to strike an arc, so having it on for 4 hours can make it last longer than switching it off and on again for two two hour stints.

    Gary.

    Flash it with 4800 firmware and the movie preset is pretty good. It comes very close to my 'calibrated' settings.
