philips 105e - unable to change the hour glass look alike display on my screen

first of all, forgive my english...
this is some one else message which i modify to fit my need...

My monitor (philips 105e) becomes hour-glass look alike style. the left and right sides of the screen are scrunched. I tried to move the view area of my screen on the settings on the monitor itself, and it's as if the monitor lost the right and left sides. my whole screen is scrunched, but visible. I did not hear any odd noises or anything. please help...
