Hello i just bought a new ASUSg73jw lappy, which is great..but recently i have noticed that the screen is not displaying colors correctly...it looks like some patches when i set certian images as background.It looks like pixels..i have updated my Nvidia gtx460m drivers and still getting the same problem......do any of u know what exactly is going on?????

i already sent this to ASUS tech service they told they fixed the issue but i can still see the discoloration of some images...
Any help wil be appreciated..THANKS
