TROUBLESHOOTING
Check if your graphics card's resolution or frequency is within the range supported by your monitor
and set your graphics card to the recommended (optimal) resolution in Control Panel > Display >
Settings.
Not setting your graphics card to the recommended (optimal) resolution may result in blurred text, a
dimmed screen, a truncated display area or misalignment of the display.
The setting method may differ depending on the computer and operating system, and some resolu-
tions may not be available depending on your graphics card's performance. If this is the case, contact
the manufacturer of your computer or graphics card for help.
Some graphics cards may not support the 1920 x 1080 resolution. If the resolution cannot be dis-
played, contact the manufacturer of your graphics card.
NOTE
The display color is abnormal.
Does the display appear discol-
ored (16 colors)?
Set the color to 24 bit (true color) or higher. In Windows, go to
Control Panel > Display > Settings > Color Quality.
Does the display color appear
unstable or monochrome?
Check the connection status of the signal cable and connect it
properly, or reinsert your PC's graphics card.
Are there spots on the screen?

black) may appear on the screen. This is normal for an LCD screen.

Are images displayed using
HDMI input without sound?
Make sure that the headphone port connections are made prop-
erly.
