The screen image looks abnormal.
Problem Action
Is the screen position wrong? • Check if the graphics card resolution and frequency are supported by
the product. If the frequency is out of range, set to the recommended
resolution in the [Control Panel] [Display] [Setting] menu. (The
settings may differ depending on your operating system.)
The screen is displayed abnormally. • The proper input signal is not connected to the signal port. Connect
the signal cable that matches with the source input signal.
• Condensation may appear on the screen. It will disappear in a certain
period of time after the product is powered on.
- The condensation formed inside the product is a natural
phenomenon and is not covered under warranty. (IPX6 is a standard
to protect the product from 100L of water per minute and not from
infiltration of moisture in the air into the set.)
The screen’s brightness seems dark. • Change the screen brightness settings.
• Check the Easy Brightness Control settings.
• If the internal temperature of the enclosure rises, the screen’s
brightness may darken.
Make sure to regularly clean the heat exchanger within the enclosure.

turned off.
• If you use a fixed image for a long time, the pixels may be damaged.

contrast (black and white or gray), this may cause image sticking. This
is normal for LCD screen products.
