Visual impact of projected slides, lost?

My pet peeve about digital projectors is the horizontal chip. Slide projectors display horizontal and vertical images the same size. When the digital projector shows horizontals full frame the verticals are smaller with big borders on the sides. To show both formats the same size, you have to make the horizontals the same smaller size as the verticals but now they project with borders around all four sides. And the projection must be done at a higher magnification to fill the screen with a loss in resolution.
A square chip in the digital projector would allow for a uniform presentation of both horizontal and vertical images at maximum resolution. However, the chip makers seem to have little interest in catering to photographers. Business presentations are the larger market, and photographers have not been vocal in their dismay.

Doh! you'd think the geniuses who design these things would realize that. The problem is that the nerds only think about Powerpoint presentations when they design those projectors!

Sounds like a market niche needing to be filled...
