Speaking — well, writing, actually — of my note-book computer and its display:
Instead of replacing the original glossy display with another, I chose to replace it with a non-glossy
matte display. Of course, I did this hoping for some improvement, but the improvement is substantially better than I had anticipated. For example, unlike before, the screen is now comfortably readable when (to conserve power) dimmed to the preset level for running on battery.
