Have gained me the projector, if times again all foreseeable colleagues have simultaneously borrowed the equipment of the school (such as just before Christmas, -D). Since this low-cost part does not have speakers and a connector to add, you have to be connected to the source a. Run a multimedia player with 4-pin jack output via a jack / RCA adapter cable to the projector => yellow plug in the projector-RCA connector, the white and red of the active speakers. Projection Distance ok for a normal classroom., It does not have to be perfect dark. About problems with the resolution, no one has complained. Fan is barely noticeable and (great!) Has no long cooling phase! The device is very light and has the active speakers and the cables found together in an underemployed 15-inch laptop bag shelter and is so for me at any time in "emergencies" within reach.
