    Couple of interesting CEDIA links for us digital guys!

    First is a link to all the DLP/LCD news:
    http://livefromcedia.com/article_140.shtml

    Next is a link to some nice piccies, mostly of the new DLP projectors (Sharp 12k, Marantz, Donino and the new Samsung etc):
    http://www.avsforum.com/avs-vb/showthread.php?s=&threadid=298767

    Word is that the new Samsung has a built-in auto calibration device for its display! Sounds like a life-saver! The new HD+ chip also seems to have made a significant impact - the Sharp 12k is reported as having a 5000:1 contrast ratio!

    No news of the NEC HT1100 other than denials of its existence (hey, NEC have shedloads of the HT1000 to sell yet so what do you expect them to say!?)

    Paul,

    The Samsung does not have auto calibration. Once you've fed it the CIE co-ordinates you measure in your room with a spectroradiometer and the luminocity values it will work out calibrated temperatures. Obviously these figures change with room decor, partnering equipment and screen type. It just makes it easier to do for ISF guys. It also has neato colourspace maping that is too confusing to explain just now as I am suffering from lack of sleep.....

    HD2+ chip is not the reason the Sharp can get that high a contrast ratio. It is being done electronically and reduces light output to under 500 LUMENS I think, but will check. Without enabling the electronic contrast enhancement it's still around 2-2500:1.....and that is not at calibrated settings so reality is it's alot less probably.

    Sort of Keyser. It has a lens cap and auto software that will calibrate using internal test patterns firing on to the tri-stimulus device in the PJ. A step in right direction of course.

    It will not take in to account partnering equipment, or the room and screen itself which are all part of the display chain. Having been in a room with three Measurement device manufacturers and a pile of calibration specialists COMPARING tri-stimulus devices and spectroradiometers I can say that measuring direct in to lens of a device v off screen can make a difference. I do applaud their attempts though!
