had connected my music system to the comp and kept the speakers right next to the monitor. did notice some distirion on the monitor when i did.. so i moved them slightly farther apart and it looked fine. one month down the line.. just moved the speakers away and theres this nice huge dark glob at the bottom left of my screen!! is there anything i can do about this? it lookss fine if the speakers are kept the way they were. What do i do??
