• The ambient temperature of the monitor may be low. When used in
the ambient temperature less than about 15 degrees, it may cause
lower luminance. It happens in an operation of the panel protect
circuit, and this is not a malfunction. The luminance will recover by
turning on electricity for a while.
• Setup-Frequency in RGB input may be set as PC mode. When set
as PC mode, the luminance becomes lower about 10% than it is
set as Movie mode. This is not a malfunction though. If you do not
mind flickering on the display, please use in Movie mode.
