    IM thinking about getting the new Samsung DLP, 43 inch hln series soon to be released.
    Can anybody inform me how isf calibration will be done on dlp?
    1. do you have to refocus dlp? like crt.
    2. is there any new geometry problems or is that a thing of the past?
    3. Does it still need color calibration? and do you have to adjust the grey scale on every input or just one?
    4. can I line the tv with felt to stop reflections?

    Just a few questions there to keep you going.
    Carl.

    Carl,

    You can focus a DLP.
    Geometry possibly, but convergence should not be an issue.
    Yes, it most definitely needs color calibration. How the grayscale is calibration is performed is dependent on each make and model.
    Yes, you can line these with duvetyne to limit reflections. I am calibrating one of these this weekend where lining the set will most likely be done. I will try to post my results when finished.

    Thanks David, I would love to see the results from the tv. Would the ISF results be the same on another set.
    I mean, will the red cut, and blue drv etc, be the same on every set in the same series?

    CRT, all sets are different, but because DLP is digital so I can imagine that there should be one setting that is right on all tvs in that series?

    Carl.

    Carl,

    Most likely the answer is no. This is due to parts tolerances inside the actually set itself. Capacitors, transistors, etc...can have anywhere from 2%-10% parts tolerance. This means that they will give different results. Most calibrators usually notice these problems in DVD Players when setting a brightness or contrast adjustment.

    I have a new Samsung sir-ts160 direct tv, high der reciever.
    It has the option of video output of 720p or 1080i, if I get the DLP to which eccepts 720p should I use that setting?
    Is the the resolution the same through the 720p as 1080?
    Any advise.
    Carl.

    David, How much would it cost to get the Samsung DLP calibrated?
    Do you live in NEW YORK?
    I am interested.
