    Re: What type of display are you guys watching Vudu on?

    I still don't get the "color wheel" concept. I have a DLP projector in Oregon and I thought it was all about the mirrors. It does have an expensive halogen bulb but no wheels that I know of.

    A three-chip DLP projector uses a prism to split light from the lamp, and each primary color of light is then routed to its own DMD chip, then recombined and routed out through the lens. Three-chip DLP projectors can resolve finer gradations of shade and color than one-chip projectors, because each color has a longer time available to be modulated within each video frame; furthermore, there won't be any flicker or rainbow effect like with the single chip solution. Like three-tube CRT projectors, the optics for some three-chip DLP projectors must be carefully aligned. But it's more common to use a prism which makes it necessary for only one optic, instead of three, and therefore removes the problem of color separation.
    According to DLP.com, the three-chip projectors used in movie theaters can produce 35 trillion colors, which many suggest is more than the human eye can detect. The human eye is suggested to be able to detect around 16 million colors, which is theoretically possible with the single chip solution. However, this high color precision does not mean that DLP projectors are capable of displaying the entire gamut of colors we can distinguish (this is fundamentally impossible with any system composing colors by adding three constant base colors).

      This is the projector I have at my place in Oregon:

        Thats a 3 chip, read about single and triple chips here:

          I have an RP DLP set. there are no 3 chip Rp DLP sets. And any front 3 chip DLP sets are over $20K for 1080P home projectors.

            In case you are referencing my post, I understand that. Just pointing out his projector is a 3chip design.

              Mine cost only 9K

              Replacement bulbs cost $600+

                Wow! I didn't know 3chip 1080P DLP projectors had dropped so much.
                Maybe soon they can replace the lamp in the front projectors with an LED source. I know they were supposed to have some come out soon, but I think it was just for a business application.

                EDIT: That I forgot that's a 788P projector so 1080P 3 chip projector must still be much. much higher.

                  The model I posted isn't the exact model I have. I'm not in Oregon right now so I can't look to verify if it's 729 or 1080 res. But since I bought several years ago it's probably 730.

                  What I would like to know is what kind of lumens can an LED put out. Is it only good for rear projection tvs or can you actually project onto a screen.

                    You'd be amazed at what some of the new ultra-bright LED light engines can put out. I've seen LED arrays that will blind you if you look into them.

                      Cool...

                      I know that a big factor with LCD tvs is the switching/latency speed to eliminate blurring. I believe the current standard is about 4ms.

                      Do you have any idea what it is for these ultra-bright LEDs??

                      I'm really inteerested baecause I've never read about these until arronwt mentioned it.

                      BTW How's your eyesight today??

                        Back of topic: Since I'll be in Orlando on election day (yes, Election day in Florida - WHOHOO!!!), I voted this morning!

                        Then again, I live in a state where my vote is meaningless...

                                It appears to only generate white light. So for DLP it seems they would have to stick to the 3x prisim concept or three filtered output lamps.

                                I have to admit though, it sounds pretty cool!!!

                                Did you find that recently or something that was used by the alien probes on you a Ceta Beta 9 when your were just a little mouseketeer??
