Purple hue down middle of the monitor when using the camera / All in one desktop

[Dewklaw]

When using the built-in camera, there is a purple hue in the middle of the screen. Have run diagnostics and all is fine, help.

@Dewklaw -- on your computer's screen, there are 3 "primary" colours, that can be mixed, in different proportions, to show 16 million different colours.  For example, 100% of all 3 colours gives "white".

But, if something is wrong, such that the 3rd primary colour is not being used, you can get "purple".

Thus, you have a hardware problem -- the camera is somehow interacting.  Weird.

So, can you purchase a stand-alone web-camera, and use it instead of the built-in camera in your All-In-One?
