MAKING CONNECTIONS

 CAUTION

 

If you use generic cables not certified by LG, the screen may not display or there may be image noises.

 

Do not press the screen for a prolonged time. This may cause image distortion.

 

Do not display a still image on the screen for a prolonged time. This may cause image retention. Use a screensaver if possible.

 

The plugs of the cable may become hot during operation. Do not touch the plug for a long time.

 NOTE

 

When connecting the power cord to the outlet, use a grounded (3-hole) power strip or a grounded power outlet.

 

The monitor may flicker when turned on in an area where the temperature is low. This is normal.

 

Sometimes red, green, or blue spots may appear on the screen. This is normal.
