yy
horizontal or vertical frequency range of the monitor. Please see the Product
Specification section of this manual to set the appropriate frequency.

yy
resulting in the retention of the image.
To extend the lifetime of the monitor, use a screensaver.
yy
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
yy
be flickering. Change the resolution to 1080P or the recommended resolution.
PC(or USB host device) cannot detect USB peripheral connected to USB-A port.
Did you change the OSD Menu

use USB data.
When Set “Quick Charge” Off, device will be charged slowly, and can use
yy
USB data.
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 kHz.
