                                                          Either you need to re-adjust your bit rate, this can be done through your desktop properties (on Windows. ) Or your monitor's color wheel is starting to go. If your monitor is new take it back where you bought it and get a replacement. If your monitor is a few years old it would be cheaper to just replace it.
