    Hello,
    What surprised me recently is - switching on my LG-Phill 30" LCD set produces on completely black screen wide light up spots especially visible from aside.
    After 10-15 min the set is warmed up and the screen becomes smoothly and equally light up.
    I guess this is because of the soft polarizer coating that changes its surface flatness with the screen temperature change.
    However I'm interested if this happens with the other manufacturers LCD screens?

    I've recently noticed that when first turned on, the top left corner of my ViewSonic N3000W is slightly brighter than the rest - not sufficient to be annoying, just noticeable on some material. Within about 15 minutes or so, the screen gradually becomes evenly lit.

    No idea why - the backlight is only on the left hand side of the screen, I think, but you may be right about it being a heat-related effect.
