    Brightness and ND filter on 4805

    Hello,
    Since i bought the projector i had issue with the brightness of the image.. it was to bright so the black seems..well bright :roll:

    Now i´m considering a ND4 filter, i already have ND2 filter but even with it still bright.

    I dont´want to over do it... so this is why i ask.

    My screen is 72" and it has 38.7 lamberts (according to infocus excel calculator).

    What do you think?.. a ND3 will be perfect but i don´t think they do ND3 filters.
Working...
