Did you know the LCD projectors you see in the classrooms require maintenance? To prolong the usefulness and efficiency of the projectors the manufacturer recommends they be periodically cleaned. An over-accumulation of dust inside a projector causes overheating and premature failure of the projector. Some projectors have a filter that require cleaning while other are filterless, however they require vacuuming to clear them of dust lodged inside. If you see a message on a screen indicating the projector filter needs cleaning please contact email@example.com with the room number where the projector is located.
Additionally, if you have ideas about new display technologies you would like to see in our classrooms please let us know. Your suggestion will be given serious consideration and possibly increase the learning experience at LTU.
