Es el mismo documento que digo yo...
He leido mal, o qué?

Cito textualmente:

"After the hundred-hour break-in period, during the next nine-hundred hours:
- Continue to retain the picture setting at 50% or less.
- Limit the use of 4:3 aspect ratio mode (traditional picture size that does
not fill the entire screen) to 15% of viewing time."

No hay nada que hacer

Saludos
