Sounds like one of the RGB signal lines in the cable may be shorting. If bright red, green, or blue pixels on your monitor go to black at the same time as the white dims, then that's almost certainly it. White is a lot more obvious because it takes up more of the screen, but pay attention to the color changes too, and note which it is (red green or blue) if you take it in for repair. (White is made up of all three colors, so when one color goes out, it's still fairly bright). It could also be an RGB line short inside the monitor, but if wiggling the connector a bit affects the problem, then it's most likely cable-related.
