Screen display is unstable and shaky / Images displayed on the monitor leave shadow trails.
Did you select the appropriate
resolution?

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.
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.

TROUBLESHOOTING
y
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.
y

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 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.
y
Some video cards may not support 3440 x 1440 resolution. If the resolution cannot be displayed, con-
tact the manufacturer of your video card.
