I recently bought one off Ebay and I'm not sure how to connect it to my computer. It didn't come with any cables or instructions. I wrongly assumed that all projectors had a place to plug in a monitor cable. Naturally the one I bought doesn't. I was hoping somebody that's had this model might be able to help. Is there some type of adapter available that would allow the use of the monitor cable? This is the only video out connection I have on the computer. Thanks.
