I just received my Piano HE-3100 DLP projector that I paid only $1999 for. I guess they are having a sale to get rid of them on their home web site. I heard that the company is not selling enough of them so they will be discontinued but still offer any repairs needed. My question is where do I go to find the proper way to calibrate it? One review says red +17, green +8 and blue 0. Another says red 0, green 8 and blue 12. Should I buy one of those DVD's that help you? Thanks!
