As a reflective single-chip system, DLP delivers high intra-image contrast in rooms with ambient light, so fine structures on a light background such as text, spreadsheets and CAD drawings keep stable contours. The dynamic contrast of 3,000,000:1 is achieved via laser modulation and provides depth in darker image areas.\u003c\/p\u003e\n\u003cp\u003eThe integrated 15 W speaker provides basic sound in the meeting room.
