an accident that results in death or serious injury. Furthermore, when installing on a wall, a UL standard certified wall 
hanging bracket (VESA 400 × 400) must be used.   

An apparatus with CLASS I construction shall be connected to a mains socket outlet with a protective ear 
thing connection.   

AC Power Supply Cord   

The Display is designed to operate on 110 - 127 V AC, 50/60 Hz.   

Ensure that the mains plug is easily accessible.   

Do not use any power supply cord other than that provided with this unit.   
• Doing so may cause fire or electric shocks. 

 

Securely insert the power cord plug as far as it will go.   
• If the plug is not fully inserted, heat may be generated which could cause fire. If the plug is damaged or the wall 
socket plate is loose, they should not be used.   

Do not handle the power cord plug with wet hands.   
• Doing so may cause electric shocks.   

Do not do anything that might damage the power cable. When disconnecting the power cable, hold the plug, 
not the cable.   
• Do not make any modifications, place heavy objects on, place near hot objects, heat, bend, twist or forcefully pull 
the power cable. Doing so may cause damage to the power cable which can cause fire or electric shock. If damage 
to the cable is suspected, have it repaired at an Authorized Service Center.   

If this Display will not be used for a long period of time, unplug the power cord from the wall outlet.   

If problems occur during use   

If a problem occurs (such as no picture or no sound), or if smoke or an abnormal odor is detected from this 
Display, unplug the power cord immediately.   
• Continuous use of this Display under these conditions might cause fire or permanent damage to the unit. Have this 
Display evaluated at an Authorized Service Center. Services to this Display by any unauthorized personnel are 
strongly discouraged due to its high voltage dangerous nature.   

If water or foreign objects get inside this Display, if this Display is dropped, or if the cabinet becomes 
damaged, disconnect the power cord plug immediately.   
• A short may occur, which could cause fire. Contact an Authorized Service Center for any repairs that need to be 
made.

• The PC text quality is optimum in HD 1080 mode (1920 x 1080, 60Hz).   

• Your PC display screen might appear different depending on the manufacture (and your particular version of 

Windows).  

• Check your PC instruction book for information about connecting your PC to a monitor.   

• If a vertical and horizontal frequency-select mode exists, select 60Hz (vertical) and 31.5KHz (horizontal). In some 

cases, abnormal signals (such as stripes) might appear on the screen when the PC power is turned off (or if the 
PC is disconnected). If so, press the [INPUT] button to enter the video mode. Also, make sure that the PC is 
connected.  

• When horizontal synchronous signals seem irregular in RGB mode, check PC power saving mode or cable 

connections.  

• The display settings table complies to the IBM/VESA standards, and based on the analog input.   

• The DVI support mode is regarded as same to the PC support mode.   
• The best timing for the vertical frequency to each mode is 60Hz.
