Yeah, I've looked for some kind of polarising film but haven't had much luck so far. Even though I did suggest this as a possible cure in the first place I'm not very confident about it actually working. I'm also not sure whether it would darken the actual display too much either. Still, I'd like to try it all the same. I'll let you all know if I find any polarising film and whether it helps at all.
