    Question Professional PJ's (DLP) in theaters


    I've wondered how these differ from home DLP/Displays.

    • How do they display (resolution/24hz??)
    • How come people do not see rainbows?
    • Are they Calibrated professionally?


    Just was curious, especially the first question.

    Let me try answering these


    • How do they display (resolution/24hz??)

    Most digital cinema projectors do a multiple of 24... like 72 or 96 so you don't see flicker.

    • How come people do not see rainbows?

    You don't see Rainbows because most digital cinema projectors are 3 chip DLP's...the rainbow effect comes from having a color wheel on a single chip DLP

    • Are they Calibrated professionally?

    From what I know the answer is YES..I have a close friend who works for the Academy of Motion Pictures and this is what he has told me.
    Now...digital cinema projectors calibrate way differently then Home units. On digital cinema projectors you shoot the white point and the primaries input the x,y values and the projector does the rest...kind of cool.

    Hope this answers your questions.

    Thanks Ray! So other than a full home setup calibrated properly, it's the best way to see a move.

    What do these 3chip PJ's cost? Bet the screen aint cheap either

    Well...some thing like a Christie HD3K is around $25,000
    That could be used for Home Theater

    Hi Guys,

    I have been calibrating Digital Cinema grade 3-chip DLPs for years now for very upscale clients. Ray is right on every point. Actually the calibration process that he describes is a TI (Texas Instruments) utility built into the light engines that the PJ manufacturer has to enable. In fact, I own a Samsung SP-A900B 1-chip DLP projector designed by Joe Kane that uses the same utility. Calibration produces extremely accurate results with this method, and in the case of my Samsung I also get a 5400K grayscale for Black & White material automatically. It is brilliant. Also interestingly enough Samsung had this utility built into their 1-chip DLP RPTVs years ago. They were amazing!

    You are correct on the Samsung DLP RPTV..I had a Samsung years ago..and my first venture into the service menu I was lost...till it was explained to me....after that I loved there correction system..think it was called "CCA"
    Guess all the info that I got from my buddy in the commercial cinema industry was right.

    Check out film-tech.com for info such as these. I've seen many DCI PJs go for 100k easy. One of my favs is the Barco DP2K-2.
