I am currently shopping for a new projector for our conference room, which we use with a PC for presentations, etc.. The cables are already run throughout the attic and down in through the ceiling of the conference room. The cable is VGA (standard blue female jack with three rows of pins, etc). All the projectors I am seeing are listing the computer compatibility as VESA, but when I look at the picture of the back pannel, I see the blue input that says "computer." Am I missing something? I've never heard of this "VESA" input, and I don't want to buy a $700.00 projector and it ends up being non-compatable. Any thoughts would be appreciated. Cheers!
