About persistent images
• Displaying a still image for a long time can create a persistent image or stain on the screen. If you intend to leave the
display on, but will not use it for a long time, set the power-saving mode or a screen saver on to protect the screen.
• An LCD panel is made up of millions of sub-pixels. Due to the technological constraints of LCD panel manufacture,
approximately one out of every 1 million sub-pixels appears either brighter or darker than normal.
To calculate the number of sub-pixels on your LCD panel, multiply the Max. Horizontal Resolution by the Max. Vertical
Resolution, and then multiply that result by 3.
Example: If the maximum resolution of your LCD panel is 1680 x 1050, the number of sub-pixels = 1680 x 1050 x 3 which equals
5,292,000.
Clean the product with a soft dry cloth.
• Do not clean the product with a flammable substance such as benzene
or thinner, or clean with a wet cloth. This can cause a problem with the
product.
• Do not scratch the screen with your fingernails or a sharp object.
This can cause permanent scratches and damage to the product.
• Do not clean the product by spraying water directly onto the product.
If water enters the product, it can cause fire, electric shock, or a problem with
the product.
• Do not use a supersonic humidifer near the monitor. A supersonic
humidifier can cause a white stain to appear on the high-gloss portions
of the product due to the inherent characteristics of the high golss
material.
The appearance and the color may differ depending on the model.
