Video upgrades/improvements

but I would like to think that any device would display the image as what it is.

Yes, but what is "it"? I'm under the impression that the foundation of VGA is little more than 3 composite signals - one for each color. The number of vertical lines is defined by the number of horizontal sync pulses between vertical pulses. But how is the number of horizontal pixels defined? I'm not sure as it is. So the display device just sizes to fit. I think most VGA devices rely on the source to insert any black bars to make the aspect ratio correct.

If you had fed it straight composite, I think it would have sensed the lack of letterbox lines and displayed it as 4:3. But I don't think that logic exists for the VGA input.

Thanks, I really wasn't thinking. It seems devices usually figure it out pretty well, but after thinking about that and talking with a friend that works at GenComm here in Utah, I will go back to the original plan of HDMI.

My friend just started there but said they do work for the Church and are both retrofitting old buildings and building new buildings with HDMI equipment. Extron seems to be the supplier of choice.
