NOTE
•
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.
•
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.
•
Check if the graphics card's resolution or frequency is within the range allowed by the monitor and in Windows set it to the recommended (optimal) resolution in Control Panel > Display > Settings. (The settings
may differ depending on the operating system (OS) you use.)
•
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.
•
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.
•
Normal graphics cards do not support 1280 x1024 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?
Set the number of colors to 24 bits (true colors) or higher: In Windows Control Panel > Display > Settings > Color Quality (The settings may differ depending
•
on the operating system (OS) you use.)
•
Check if the signal cable is connected properly. Reconnect the cable or reinsert the PC's graphics card.
•
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.
