So will this patch allow the game to fill the screen without leaving 2 black spots on each side of the game in short resolution.

I have tried many alternatives that people have said, these do not work
=/ the game would need 1280x800 reso at least to fit my monitors

=/ but i just want D2 to fill the monitor at the reso's it has

I don't think you really want to stretch the image to fit, do you? It's going to make everything look fat and blurry.
