After 89hours of use I find that picture seems to have gone down in contrast. I always use the dynamic mode which gave me wonderful results in the begining but now seems just ordinary. I don't know if it is because I have got used to it or if the lamp has aged. I am using the free 6ft screen that came with it, but I am seriously considering putting up an 8ft pull down screen but now I am wondering if on the 8ft screen I will loose even more contrast and brightness? The bigger the screen the duller the picture, is that correct? Also I usually use the pj once a week and when not in use I unplug it and put it away, is it better to leave it in standby when not in use? I am using it with a pioneer dcs303 s-video. Any thoughts would be much appreciated.
