i have purple haze in the corners of my screen. why is this ??? can anyone help

Do you have speakers or a strong microphone positioned near there? If so those may well be the cause. Move them a bit and see what happens.

no i dont what else could it be

is a tv near by? do you have a good wireless mouse nearby? is your printer on, and is it near by? do you have anything on your monitor that can be causing a electomagnetic force?
