Added functions for the economical use of energy and the reduction of total cost of ownership

Equipped with an automatic Eco Mode to automatically control picture brightness

Equipped with an automatic Eco Mode to automatically control picture brightness

Eco Mode reduces light intensity automatically and imperceptibly when switching from white screens like charts or bright images to a dark screen or image. This function can reduce the power consumption by up to 24%. Both the projector and its remote are equipped with an Eco button for easy setting of Eco Mode.

Lengthen lamp lifetime

Replacement lamp

Using Eco Mode can increase the lamp lifetime to 3500 hours*. Furthermore, the low-energy design keeps power consumption to 0.2 W during standby (low energy consumption), which helps reduce total cost of ownership.

  • *This is not a guaranteed value.

The Carbon Meter lets you visually check the amount CO2 you reduced

Equipped with an abundance of handy functionality.

High brightness up to 4200 ANSI lumens

Built-in monaural speaker with a powerful 10 W output

  • *Not available on M420XV

Computer-free presentations

The projector allows you to project images without a computer. Simply insert a USB memory device loaded with image data directly into the projector.
