LCD Burn In

[Jim]

About a year ago, a cable guy came here to do some work and warned me to not have the black bars on the sides of non hidef tv channels. He said it could cause burn in. Something I haven't seen in many years.

Yesterday, I noticed a black line on a hidef channel and thought it was just the recording. Today I see, my office hidef lcd tv has burn in.

Anyway, I have seen many products that claim they fix the problem but has anyone had this problem and fixed it. I understand that Macs have this problem more than any other monitor. There has to be a Mac owner that has had and fixed this problem.
