Swapping Function
You can swap the main screen and the sub-screen when the PIP/POP/PBP function is used.
Spectacle Function
The screen center area is close to a 4:3 ratio and the outskirt area is expanded by more than 15:9.
Therefore, the different screen ratio is applied for each area. Because most ordinary people
concentrate their focus on the screen center, a non-linear ratio increase at the outskirt area is not
recognized, which makes it possible to watch 4:3 TV screen with a wide screen.
However, the spectacle function is useful in watching TV or motion pictures but is not suitable for the
PC environment in which you perform graphic or document work.
Sleep Function
When watching AV/HDTV/TV – The monitor will be automatically turned off after a certain period of
time.
Press this button repetitively to select an appropriate time duration.
