Problem Solution
Uneven screen color/brightness If the screen is viewed from a certain angle, there may be
uneven colors or brightness due to the LED structure of the
LCD panel. This is a technical limitation of the LCD
technology and is not a defect. It does not affect the
performance of the display.
No sound Check the following:
• Have you turned on the mute function on the machine
or the input source device? Turn off the mute function
or increase the audio volume level and try again.
• Are there any loose cable connections? Make sure that
all cables are connected firmly.
• Check that the correct audio source is selected. For
details about how to select an input source, see
page 30 "Sound Menu".

• Have you chosen an unsupported output resolution on
the computer? Refer to page 48 "List of Video Input
Signals Supported by the Machine" to select a
supported resolution and try again.
• Use the Auto Adjustment function to let the display
automatically optimize the computer image. For details
about the Auto Adjustment function, see page 32
"Screen Menu".
• If the result of the Auto Adjustment function is not
satisfactory, use the Phase, Clock Frequency, H.
Position and V. Position functions to manually adjust the
image.
• Reconnect the cable, and then check that the cable is
connected correctly.
• Save the changes to the file you are working on, and
then quickly press and release the power button of the
display. When the machine shuts down, press the
power button again to restart the machine.
