NOTE
•
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 in Windows. (The
settings may differ depending on your operating system)
•
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. Some resolutions 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 3840 x 2160 resolution. If the resolution cannot be displayed, contact the
manufacturer of your graphics card.
The display color is abnormal.
Does the display appear discolored (16
colors)?
Does the display color appear unstable
or monochrome?
Are there spots on the screen?
The 'Unknown Monitor' message appears when the monitor is connected.
Did you install the monitor driver?
•
Set the number of colors to 24-bits (True Color) or above: Control Panel
> Display > Settings > Color Quality in Windows (the settings may
differ depending on your operating system).
•
Check the connection status of the signal cable and connect it properly
or reinsert your PC's graphics card.
•
When using the monitor, pixelated spots (red, green, blue, white or black)
may appear on the screen. This is normal for an LCD screen. It is not an
error, nor is it related to the monitor's performance.
•
Install the enclosed monitor driver provided with the monitor or go to
the LG Electronics homepage (http://www.lg.com) to download and
install the monitor driver.
•
Check your graphics card user manual to see if the Plug and Play
function is supported.
