Disruption-Free Learning for Small and Medium-Sized Classroom Featuring an brightness of 2700 ANSI lumens, ultra-sharp contrast ratio of 13000:1 and a XGA resolution, the cost-effective and eco-friendly MX503 offers a stunning full-screen presentation with the finest details regardless of the ambient light level. The Eco Blank mode allows teachers to blank the Projectorection screen whenever they need to direct their students’ focus back on them – or simply when the Projectorector is not in use. When activated, this special feature dims the lamp power automatically, lowering the total power consumption by up to 70%. The SmartEco mode is designed to use only the exact amount of lamp power a Projectorector needs to deliver the best contrast performance. With this feature, schools get to provide students and teachers uncompromised Projectorection quality and reduce the total cost of ownership by extending the lamp life and lowering power consumption. There will be times when a Projectorector is turned on without a display source, such as a classroom PC or notebook. To avoid a Projectorector from running with full lamp power, BenQ created the No Source Detected Mode to lower the Projectorector lamp brightness to 30% after the Projectorector has remained unconnected to a display source for more than three minutes.
