Take a look at the open source viewer of OpenEXR at
 http://www.openexr.com

It uses OpenGL in two alternative ways:
 1. Uploads the image to GPU after each change.
 2. Uses fragment program to change the image located in GPU.

It could be that the fragment program of OpenEXR would work
for you "as is" (if you have the required card).

Some video player software uses similar techniques. Look around.
