I just got back from a business trip and came back to find my wife watching "Big Brother Live" on E4. Apparantly, she has been doing this a lot over the last few days. To my horror, I noticed the 'Red Dot' at the top right of the screen.. Fortunatly, it hasn't done any damage, but I am wonder how long it would have to be there to burn the screen. Its not like a 'dog' which is transparant, the 'red dot' is solid in colour. Saying that, there are ad breaks ever so often, so the dot isn't ALWAYS there. After whiching a VERY large rear projection TV in my hotel bar all week, which has been destroyed by them running CNN all day, I am a little paranoid about this. Is there a real risk of an on-screen logo doing any harm??
