I have a small spiderweb crack on my LCD glass. I know that it's impossible to fix, but if I could seal up the cracks with some clear epoxy or something, I may be able to minimize the effected area.
You really can't do that. The LCD glass is behind a protective plastic covering that isn't easily removable. You'd probably do more damage than good by trying to get to the cracks to try to seal them up. You'd have to replace the LCD panel itself or get another monitor.
