Ghost lines in my new ViewSonic LCD Va1716w

Recently i bought a new ViewSonic Va1716w LCD monitor and am running it on Asus A7v400 MX SE motherboard and the LCD is connected to GeFORCE FX 5500. I am experiencing ghost lines which are extremely clear in black or dark backgrounds and are somewhat horizontal but random (not constant on the screen). I also ran the LCD on the built in graphics card in the motherboard but the problem persists. Can anyone guide out of this problem??

check if the power connector of the lcd has 3 pins or 2,

3 pins means that it is grounded while 2 pins means it is not.

chk with the other monitor ! may b the fault is in your power supply or the graphix card
