I use a HOYA PL filter and all I can say is, it looks fantastic shadows are really black no joke. Only one thing, room must be black aswell. I'd say you loose about 40% of lumen but the picture looks so much better and it gives you a 3D looking effect that you only get from CRT projectors. I tryed lots of difrent filters and found this to be the best of the best.
Note, Filter is galss and and around 100$ but absolute worth it. This works with all sources and has no need for RGB adjustment as you can just turn the filter to calibrate.
Cheers
