Texas Instruments answers the challenge of new LDC and LCoS projectors with the new Dark Chip 4 1080p DLP digital micromirrror device. Claimed to produce a native contrast ratio of up to 15,000:1, it will soon appear in DLP projectors from Marantz, SIM2, BenQ, and, in 2008, likely others as well. An impressive TI demo utilized a new SIM2 DC4 1080p projector. The modified Samsung in the photo also sported a DV4 chip. I'm not sure where the 100,000:1 claim came from, though. A tad optimistic, perhaps?
