The Samsung SP-H700AE, the predecessor of the currently discussed SP-H710AE, was reviewed in the May '05 issue of Home Theater magazine, and here are some pertinent measurements vis-a-vis the Sharp XV-Z12000 MARK II, which was just reviewed by the same magazine using the same instrumentation and screen, an 87-inch wide, 1.0 gain Da-Lite Da-Mat screen :
FULL FIELD 100-IRE white } 15.92 foot-lamberts > Samsung
} 7.263 foot-lamberts > Sharp
FULL FIELD 0-IRE black } 0.011 ft-L > Samsung
} 0.002 ft-L > Sharp
......These figures are for best black level.................
----------------------------------------------------------------------------------------------------------------
FULL FIELD 100-IRE white } 20.83 ft-L > Samsung
} 22.09 ft-L > Sharp
FULL FIELD 0-IRE black } 0.014 ft-L > Samsung
} 0.016 ft-L > Sharp
.......These figures are for brightest image...............
-----------------------------------------------------------------------------------------------------------------
The Sharp also has a "medium" mode which measured 11.6 ft-L (FULL FIELD/white) and 0.005 ft-L (FULL FIELD/ black) and a "high-contrast" mode, measured at 10.6 ft-L // 0.003 ft-L ....So the Sharp does offer a few more options.......
-----------------------------------------------------------------------------------------------------------------
BEST CONTRAST RATIO } 1488.1 Samsung
} 3632.1 Sharp
---------------------------------------------------------------------------------------------------------------
ANSI CONTRAST RATIO } 370.1 Samsung
} 525.1 Sharp
----------------------------------------------------------------------------------------------------------------
Both units received ratings of "excellent" for DC RESTORATION and for COLOR DECODER
----------------------------------------------------------------------------------------------------------------
"Out -of-the-box" measured gray scale tracked very close to D6500 for both units and calibrated even closer afterwards.....
----------------------------------------------------------------------------------------------------------------
The Samsung had excellent processing, picked up the 3:2 sequence very quickly and processed incorrect 3:2 sequences and video with equal dexterity.
The Sharp picked up the 3:2 sequence quickly, with video processing only a little better than average which displayed some "jaggies"
------------------------------------------------------------------------------------------------------------------
After calibration the Samsung was described as "downright impressive/ with an accurate & almost relaxing image/colors, midtones and skintones all looking very realistic".... Some "steps" observed in test signals for gray ramp, although rarely noticed in actual video material.....The reviewer mentioned the "disappointing black level" measured, however i am not sure exactly which TI chip the SP-H700AE uses, it could very well be the DC2 instead of the DC2+ which is apparently used by the current model, the SP-H710AE.
The Sharp had an extremely detailed image with one of the smoothest gray ramps ever seen on a digital display and "blacks" that were indeed black, although they were still higher than with a CRT...The Sharp had one of the best contrast ratios ever measured in a projector, with a "punchy" and "totally watchable" image.
------------------------------------------------------------------------------------------------------------------
THe Samsung had a very unique and interesting "trick up its sleeve", so to speak : instead of measuring several different levels of gray and making a series of adjustments, a technician just measures a red field, a green field, a blue field and then a white field; The technician then enters the light level (in foot-lamberts) and x,y coordinates for each color into the projector, and the projector automatically adjusts the gray scale, gamma and color points...."Incredibly easy and accurate", as noticed by the reviewer !
Also, even the color wheel used in this projector appears to be unique, as the RED segment has GREEN/BLUE in it, the BLUE segment has RED/GREEN in it, and the GREEN segment has RED/BLUE in it, therefore allowing the technician to adjust the color points by playing around with the amounts of R/G/B available for each individual color-segment on the color wheel, aiming to bring each primary color closer to its correct point; This "allows for extremely accurate color reproduction, regardless of any minor color shift the screen may introduce" !
The color temperature of the Samsung relative to the color points of the display's red, green and blue color-filter-wheel segments were measured as being extremely close to those specified by SMPTE, as opposed to most other digital displays measured by the same magazine, making it another "rarity" !
I can't think of any other DLP projector that offers similar color adjustability by means of such unique color wheel, or am i wrong ?
