Hello, I recently purchased a Dell 2300mp projector on ebay. I new it would have just the old VGA connection however my Dell xps 14z laptop only has HDMI output. I purchased a cable that goes from HDMI to VGA thinking this would work. When I use the function keys on laptop to send to "projector" or "duplicate" my laptop screen acts like it connected but the projector continues to "search for signal" and never recognizes ....what am I missing here? Is the projector two old for my new laptop?
