Samsung Syncmaster 720n Quick Start Guide

							PRODUCT INFORMATION (Image Retention Free) 
 
LCD Monitors and TVs may have image retention when switching from one image to another 
especially after displaying a stationary image for a long time.  
This guide is to demonstrate correct usage of LCD products in order to protect them from Image 
retention.  
 
WarrantyWarranty does not cover any damage caused by image retention.  
Burn-in is not covered by the warranty. 
What is Image retention ? 
During normal operation of a LCD panel, pixel image retention doesnt occur. However, 
if the same image is displayed for a long time, a slight difference in electric charge 
accumulates between the two electrodes which encase the liquid crystal. This may 
cause the liquid crystal to build up in a certain areas of the display. Thus, the previous 
image is retained when switching to a new video image. All display products, including 
LCD,are subject to image retention. This is not a product defect.  
Please follow the suggestions below to protect your LCD from image retention  
Power Off, Screen Saver, or Power Save Mode 
Ex) 
zTurn the power off when using a stationary pattern. 
zUse a Screen saver if possible 
zSet the Monitor to power off with the PC Display Properties Power Scheme.  
 - Turn the power off for 4 hours after 24 hours in use 
- Turn the power off for 2 hours after 12 hours in use  
- Screen saver in one color or a moving image is recommended.  
Suggestions for specific applications 
Ex) Airports, Transit Stations, Stock Markets, Banks, and Controlling Systems  
We recommend that you follow set up of your display system program as below: 
 
 
Display Information together with Logo or Moving image cycle. 
Ex) Cycle : Display Information for 1 hour followed by a  
Display Logo or moving image for 1 minute.  
 
Change the Color Information periodically (Use 2 different colors). 
Ex) Rotate the Color Information with 2 colors every 30 minutes.  
 
Avoid using a combination of characters and background color with large 
difference in luminance. 
Avoid using Grey colors, which can cause Image retention easily.  
 
zAvoid: Colors with big difference in luminance (Black & White, Grey)  
Ex)  
 
 
zRecommended settings: Bright colors with little difference in luminance  
- Change the characters color and background color every 30 minutes  
Ex) 
 
 
- Every 30 minutes, change the characters with movement.  
 
						

							Ex)
The best way to protect your monitor from Image retention is to set your PC or 
S
ystem to operate a Screen Saver program when you are not using it.
Image retention may not occur when a LCD panel is operated under normal conditions. 
 
Normal conditions are defined as continuously changing video patterns. When the LCD 
panel is operated for a long time with a fixed pattern (-over 12 hours-), there may be 
slight difference in voltage between electrodes that work the liquid crystal (LC) in a 
pixel. The voltage difference between electrodes increases with time, forcing the liquid 
crystal to lean. When this occurs, the previous image may be seen when the pattern is 
changed.  
To prevent this, the accumulated voltage difference must be decreased. 
 
Our LCD Monitor satisfies ISO13406-2 Pixel fault Class II
