Hi I've had a 19 inch widescreen display from hanns-g for around 2 years now and i've noticed that every so often the screen like gets sort of frequency looking waves . . . its really hard to explain its like it seems as if a connection isn't good or something or like loose but i've looked at it and everything is right . . . i have a macbook with a vga to mini dv adapter and i'd actually rather get the digital connection but thats besides the point. Anyway when i click like 100 times in a row on the website toolbar where you'd enter an address the problem gets really bad . . . at first i was thinking its cause i dropped it a couple times but I don't understand how it could be that because it gets worse during certain times while doing certain things . . . someone please help me thanks
