yy 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

yy 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.

yy 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 Hz.

Troubleshooting 35

NOTE

yy Check if the video 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.

yy Not setting the video card to the recommended (optimal) resolution may result in blurred text, a dimmed screen, a truncated display area or misalignment of the display.

yy The setting methods may be different depending on the computer or operating system, and some reso- lutions may not be available depending on the performance of the video card. If this is the case, contact the manufacturer of the computer or video card for assistance.

yy Some video cards may not support 4096 x 2160 / 3840 x 2160 resolution. If the resolution cannot be displayed, contact the manufacturer of your video card.
