Details: The white PT-DZ780WU 7000L WUXGA 1-Chip DLP Projector with 25.6-35.7mm Lens from Panasonic provides a high brightness of 7000 lumens, 3000:1 contrast, and dramatically reduced noise (30 dB), thanks to a carefully designed airflow control system and cooling fans. The image processing circuit analyzes the video signal frequency range for each scene by extracting data on the distribution of high, mid, and low-frequency components, bringing out fine details accordingly. The projector uses high-power 310W lamps that have a long replacement cycle of up to 4,000 hours. The dual-lamp system eliminates any type of interruption if a lamp should fail (in dual-lamp operation mode), ensuring 24/7 projection. Dynamic RGB Booster ensures remarkable balance of brightness and color reproduction. The dual-lamp system contributes to reliable operation, less downtime, and low maintenance costs.
