To reduce the risk of image retention:
• Sony recommends that you turn off the TV normally by pressing
the power button on the remote control or the TV.
• Fill the screen by changing [Wide mode] to eliminate the black
bars. Select [Wide mode] other than [Normal].
• Turn off the OSD (On Screen Display) by pressing the /
button, and turn off the menus from connected equipment. For
details, refer to the instruction manuals for the connected
equipment.
• Avoid displaying static images with bright colours (including
white), clocks or logos on any portion of the screen.
• Set the picture settings based on the ambient conditions. The
Standard Picture is recommended for home use and when
viewing content that often displays the station logos, etc.
Che significa, in italiano: NON VISUALIZZARE FOTOGRAFIE con parti colorate(anche bianche) particolarmente brillanti, orologi o loghi, ed usare una modalità di visualizzazione Standard (quindi non Brillante) quando si guarda Sky o La7.
Se non hai fatto nulla di tutto ciò non è un uso improprio
