yeah the Fn+F8 activates the CRT/LCD function. But it didn't work on my Dell Inspiron 1100. Just stuffed up my screen even more coz my menu bar at the bottom disappeared and a fuzzy inaccessable bar appeared up the top. but the black border's still there. I tried pressing Fn+F8 for like 5 times but still the same result.

thx for trying anewayz.
