Featuring a brightness of 3200 ANSI Lumens and a high contrast ratio of 13000:1, the cost-effective and eco-friendly MX507 offers a stunning full-screen presentation with the finest details regardless of the ambient light level. Offering lower TCO and optimized projection through dynamic power saving, uncompromised brightness, exquisite picture quality and optimized lamp life - SmartEcoTechnology has perfected what a DLP projector can do. With this innovation, schools and corporations are able to save up to 70% of lamp power consumption and lower maintenance costs through dynamic power saving features while bringing an ultra-vivid viewing experience into every presentation. The SmartEco Mode, which cleverly adjusts the lamp power to maximize power saving by delivering the best contrast and brightness performance using only as much light as needed. Projector lamp replacement costs make up the biggest part of the total cost of projector ownership. The LampSave Mode is designed to adjust the lamp power dynamically by content brightness level to extend projector lamp life significantly by 50%! The lamp replacement frequency is also reduced by up to 50% to lower the replacement costs. The Eco Blank mode allows teachers to blank the projection screen whenever they need to direct their students' focus back on them - or simply when the projector is not in use. When activated, this special feature dims the lamp power automatically, lowering the total power consumption by 70%. The automatic switch to Eco Blank Mode after the projector is turned on for over three minutes without a display source, eliminating unnecessary energy waste and prolonging the life of the projector lamp. When inactive, the MX507 keeps power consumption to a minimum with 0.5W standby power, achieving what was once a challenge for earlier projector models. This technological advancement in energy saving certainly helps extend the projector lamp life and lower energy costs. With the built-in speaker, the MX507 can be used as an audio system when it's on the standby mode. This saves you the trouble as well as the extra budget for getting a separate audio system.
