The manual for the projector actually shows what you need to buy. I have a Sharp projector and connected it to a laptop with a DVD player using the big sub D RGB cable and then the earphone cable to my sterio for sound.
I have since gotten a Sharp blueray DVD player -figuring it would connect easily - wrong- I needed a special cable, to go from projector's RGB D sub end to an HDMI end plug in to the DVD player. It couldn't be found in local stores, it only could be bought in this configuration on ebay. Hope this helps some.
I want to play dvd movies and/or presentations on my digital projector with one of those inexpensive ($150) portable dvd players, but there is no compatable hook up. The digital projector has computer plugs for video in from a computer and the dvd player just has rca sound and video plugs. Does anyone no of a way to accomplish this short of purchasing a laptop with dvd/cd drive ? Any help would be appreciated.
