[Hoax]

Wow that looks nasty, never seen anything like it ..

EDIT - oh wait the other thing im seeing is probably from the flash or a reflecting light on the screen :P

If you still want to know what banding is:

Its a change in color because the backlights are not even ..
It will most likely show up during camera pannings or if you have a really bad set it will show up in every occasion its best visisble on occasions where the whole screen is filled with the same colour so its easier to spot uneven patterns ..

For example when you watch sports played on grass and the camera moves to the left or right you will see one or more vertical bands where the grass seems darker or lighter than the rest of the field ..
