The black PT-DW640K 1-Chip DLP Projector from Panasonic featuring a dual-lamp system, is compact but powerful. This WXGA projector is suitable for a wide variety of applications, from education and business to museums. Panasonic's light convergence technology and the color wheel work together to achieve 6000 lumens of brightness. The RGB Booster ensures vivid, colorful images, and the original Eco Filter eliminates the need for filter replacement for up to 12,000 hours. A host of terminals and advanced management functions provide enhanced system flexibility. DICOM Simulation Mode is a medical imaging standard which helps reproduce X-ray images with remarkable clarity. Vivid Color Control technology optimizes the use of the color segment areas of the color wheel. It increases the brightness of each RGB color by minimizing the unallocated portions between the colors, to achieve truly vivid coloring. The use of a full 10-bit image-processing system provides smooth tonal expression such as natural skin tones. The liquid cooling system directly cools the DLP chip to improve performance and enable operation up to 113 F (45 C). This allows you to use this projector in a wider variety of environments, while stabilizing performance and keeping the unit quiet even in harsh conditions. The Dual-Lamp System eliminates the need to interrupt a presentation if a lamp should burn out (in dual-lamp operation mode). The Lamp Relay mode also operates the lamps alternately to enable 24/7 projector operation.
