DLP Technology DLP® (Digital Light Processing) is a proprietary technology from Texas Instruments™ that offers digital projection with higher contrast, faster response time, good pixel structure and virtually no color degradation. RS-232 Control Take control of the projector using HEX or ASCII commands via RS-232 cable. Signal Power On The projector powers on when it receives a signal through the HDMI input. This ensures the projector is turned on at the same time as the source device. Four Corner Adjustment Four corner geometric correction enables quick and easy image adjustments from any of the corner points of the image. This is ideal for uneven or angled projection surfaces.
