MagicBright refers to a new monitor feature that offers screen
display quality twice as bright and clear than that of existing
monitors. It provides display brightness and resolution most

satisfy varying user requirements. The user may easily select one
of three pre-configured brightness and resolution options by
simply pressing one of the MagicBright control buttons located on
the monitorís front.
1 Push the MagicBright button.
Push the MagicBright button again and select the desired mode.
When Text is selected, the monitor turns on normal brightness identical to
that of existing monitors, which is suitable for reading or working with text.
When Internet is selected, the monitor turns on an enhanced brightness
for Internet browsing (text and graphics), while retaining the readability of
text characters. When Entertain is selected, the monitor switches to
maximum brightness (330 cd/m2), identical to television brightness,
which is optimum for viewing entertainment programs (animation, DVDs,
television or online games).
