I have just bought myself a lovely new Fujitsu 42". The guy in the shop said running them in was a bit of a myth, but then said I could run it in low contrast if I wanted to for a bit. He suggested 50 hours. The questions: Is this really needed? Is there any hard scientific reason why this needs doing? Are there any expert links to information? I did a search on the forums under 'run in' and 'running in' and saw no other threads.
