Well, I've clocked several hundred hours watching my Pansonic PT-L300 projector, and for those of you who may be on the fence about buying this PJ, I thought I would share my thoughts on the unit after spending so much quality time with it.
You may have read about some "issues" the PJ has, so I will address them one by one:
Scanline artifacting: Once and awhile I notice it, but 98% of the time I just watch the movie. The point being that it is probably there every minute, but I just dont notice it enough to care.
Screen Door Effect: With a 9 foot-wide screen, sitting about 13 feet away, I only notice SDE on SOME screen credits and or subtitles. Otherwise it is a NON-ISSUE. Smoothscreen technology WORKS.
Colors: Never a problem, they are always rich and vibrant.
Fan Noise: Never bothers me
Black levels/shadow detail: Ah, my one major complaint. This is the one area that annoys me to this day. Of course, when I take into account the price of the projector, I can't really complain... but the poor black levels and shadow detail definitely DO distract me from enjoying whatever I am watching. Some movies, like U-571 for instance, are simply BRUTAL in displaying this shortcoming. Then again, poor blacks are endemic to all LCD PJs I think, so one can not just single out the 300U for this. In any case, I've tried using the CC05m filter and ND filter on the lens, and also a dark grey projection surface... but alls I end up with in the end is a dimmer picture and darker greys. I wish I could get used to it, but with certain source material it's just impossible to not notice. The screen is just sometimes filled with large areas of featureless dark grey.
Overall though, the sheer fact that I can watch a 9 foot image is pretty cool. With the right source material, it looks great. With comedies (not a lot of dark scenes generally), it looks incredible, even on a bare white wall. It would be darn near perfect if it could just handle blacks better. Anyway, that's my .02 on the thing.
