BenQ’s Eco Cycle System provides optimum energy efficiency to improve your overall user experience and minimizes maintenances over the life of the MH 733. In addition to having a regular Eco Mode, SmartEco Mode and LampSave Mode adjust brightness and power on the fly so you can deliver the best possible image while maximizing the life of your projector or lamp over the long term.
In addition to the color modes, Eco Blank Mode automatically activates after 3 minutes with no source detected, saving power on your projector regularly. Lastly, like most BenQ business projectors, auto-power off after 20 minutes is a standard feature for the MH733 in order to ensure no teacher or presenter wastes those lamp hours if for some reason the projector is left on for too long.
Using LampSave mode, BenQ claims to get about 15,000 hours of lamp life. Of course, if one practices common sense, such as not leaving the projector on all night with no source, that 15K number isn’t realistic. As most projectors have “eco” solutions for no source material, the “big” number, is misleading. Especially in a network environment where projectors are monitored, automatically shut down after hours, etc.
