From my previous reading on the subject, HDMI comes from the TV world, and DVI comes from the computer monitor world.

On a computer display, you want each pixel to be square and to be visible on the screen, a border around all the pixles doesn't matter.

On a TV, historically, pixels didn't exist, and the nearest concept to a pixel (I forget the term) wasn't square, it was rectangular. Showing a border around the content is not acceptable, and it should go right up to the very edge. Also in the TV world, the most important thing in the image, not the pixels.

So it's this philosophical difference, and separate histories, which means you should never try to get a TV to be a monitor, or a monitor to be a TV. Of course I only learnt this after buying a device which said it could be both.
