Did you select the appropriate resolution?
y If the selected resolution is HDMI 1080i 60/50 Hz (interlaced), the screen may be flickering. Change the resolution to 1080P or the recommended resolution.
NOTE y Vertical frequency In order to display an image, the screen must be refreshed dozens of times per second, like a fluorescent lamp. The number of times the screen is refreshed per second is called vertical frequency, or refresh rate, and is represented by
Hz.
y Horizontal frequency The time it takes to display one horizontal line is called the horizontal cycle. If 1 is divided by the horizontal interval, the result is the number of horizontal lines displayed per second. This is called horizontal frequency and is represented by kHz.
y LED can be lighted with Set OSD Menu.

NOTE y Check if the graphics card's resolution or frequency is within the range allowed by the monitor and set it to the recommended (optimal) resolution in Control Panel > Display > settings .
y Not setting the graphics card to the recommended (optimal) resolution may result in blurred text, a dimmed screen, a truncated display area, or misalignment of the display.
y The setting methods may be different depending on the computer or operating system, and some resolutions may not be available depending on the performance of the graphics card. If this is the case, contact the manufacturer of the computer or graphics card for assistance.
y Some graphics cards may not support 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?
y Set the color to 24 bit (true color) or higher. In Windows, go to Control
Panel > Display > Settings > Color Quality.
y Check if the signal cable is connected properly. Reconnect the cable or reinsert the PC's graphics card.
y When using the monitor, pixilated 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.
Do you see an "Unrecognized monitor, Plug&Play (VESA DDC) monitor found" message?
Have you installed the display driver?
y Be sure to install the display driver from the display driver CD (or diskette) that comes with your display. Or, you can also download the driver from our web site: http://www.lg.com.
y Make sure to check if the video card supports Plug&Play function.
