Projecting image from computer that is a distance away For our schools theatrical production class, we need to project an image using a projector, however the only way to use the projector is to hang it on a lighting bar (Not a problem)  The problem is that we do not have a long enough VGA cord to hook that projector up to a laptop/desktop.  I have called around and asked about a 200ft VGA cable, but at that length that would loose signal.  So I thought I would ask this form what would be the best solution to my problem.  I have thought about getting a 200 coax cable with VGA ends, but is that even possible?

Thanks in advance.
It's possible to amplify VGA for long runs, but since that's an analog signal it's usually not the best option. VGA over coax is probably more trouble than it's worth (you'd have to merge the many VGA channels somehow to use the single coax pin, and then reverse it).

VGA over Cat5e is fairly common. You still aren't running an analog signal over 200ft, but there's hardware to convert from VGA to a digital signal and then convert back at the other end with minimal latency. For example, this product, which also has a monitor port at the source end.

A less reliable option, but possibly less pricey if your projector supports it, is wireless projection over wi-fi. But like I said, this may be not reliable enough for theater application.
