LG 710S (01) PDF Document

To ensure your personal safety and prevent potential electrical shock or fire hazards, please observe the following basic rules for the installation, use, and servicing of your LG 710S monitor.

On Safety

• Use only the power cord supplied with the unit. If you use another power cord, make sure that it is certified by the applicable national standards. If the power cable is faulty, contact the manufacturer or an authorized repair service provider.

• The power supply cord is the main disconnect device. Ensure the socket-outlet is easily accessible after installation.

• Operate the monitor only from a power source indicated in the specifications or on the monitor itself.

• Overloaded AC outlets, extension cords, frayed power cords, and broken plugs are dangerous and may result in a shock or fire hazard. Contact a service technician for replacement.

• Ensure your hands are dry when holding the power plug to avoid electric shock.

• Do not damage the power cord by disassembling, bending, pulling, or heating it.

• Make sure to completely insert the power plug to prevent insecure connections which can cause a fire.

• Do not open the monitor. There are no user-serviceable components inside, and there are dangerous high voltages present even when the power is off.

• To avoid personal injury, do not place the monitor on a sloping shelf unless properly secured. Use only a stand recommended by the manufacturer. Do not try to roll a stand with small casters over thresholds or deep pile carpets.

To Prevent Fire or Hazards

• Always turn the monitor OFF if you leave the room for more than a short period. Never leave the monitor ON when leaving the house.

• Keep children from dropping or pushing objects into the monitor’s cabinet openings.

• Do not add accessories that have not been designed for this monitor.

• During a lightning storm or when the monitor is to be left unattended for an extended period, unplug it from the wall outlet.

• Do not bring magnetic devices such as magnets or motors near the picture tube.

Proper installation is crucial for the safe and effective operation of your LG 710S monitor.

• Do not allow anything to rest on or roll over the power cord, and do not place the monitor where the power cord is subject to damage.

• Do not use this monitor near water, such as a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool.

• The monitor has ventilation openings to release heat. If these are blocked, the built-up heat can cause failures and may result in a fire hazard. Therefore, you must NEVER do the following:

– Block the bottom ventilation slots by placing the monitor on a bed, sofa, rug, etc.

– Place the monitor in a built-in enclosure unless proper ventilation is provided.

– Cover the openings with cloth or other material.

– Place the monitor near or over a radiator or heat source.

• Do not install the monitor in a dusty area as it can cause a fire.

Before setting up your LG 710S, ensure that the power is turned off to the monitor, computer system, and other attached devices. Carefully set the monitor face-down with the underside facing you.

1. Align the hooks on the tilt/swivel stand with the matching slots in the base of the monitor.

2. Insert the hooks into the slots.

3. Slide the tilt/swivel stand toward the front of the monitor until the latches click into the locked position.

1. Connect the signal cable to your computer. When mated, tighten the thumbscrews to secure the connection.

2. Connect the power cord into a properly grounded power outlet that is easily accessible and close to the monitor.

Note for Apple Macintosh users: A separate plug adapter is needed to change the 15-pin high-density (3-row) D-sub VGA connector on the supplied cable to a 15-pin 2-row connector.

This function allows you to secure the current control settings so that they cannot be inadvertently changed.

To lock the OSD controls:

Press and hold the MENU button and the ◀ button for 3 seconds. The message “CONTROLS LOCKED” will appear.

To unlock the OSD controls:

Press and hold the MENU button and the ◀ button for 3 seconds. The message “CONTROLS UNLOCKED” will appear.

To make adjustments to the image size, position, and other operating parameters of your LG 710S, follow these steps. Note: Allow the monitor to stabilize for at least 30 minutes before making image adjustments.

1. Press the MENU Button to make the main menu of the OSD appear.

2. To access a control, use the ◀ or ▶ Buttons. When the icon you want becomes highlighted, press the SELECT Button.

3. Use the ◀ or ▶ Buttons to adjust the item to the desired level.

4. Accept the changes by pressing the SELECT Button.

5. Exit the OSD by pressing the MENU Button.

The following table describes the On-Screen Display control, adjustment, and setting menus available for your LG 710S.

*This function is available for designated models only.

If no image appears, please check the following:

• Is the power cord of the monitor connected? Check and see if the power cord is connected properly to the power outlet.

• Is the power indicator light on? Press the Power button.

• Is the power on and the power indicator green? Adjust the brightness and the contrast.

• Is the power indicator flickering? If the monitor is in power saving mode, try moving the mouse or pressing any key on the keyboard to bring up the screen.

• Do you see an “OUT OF FREQUENCY” message on the screen? This message appears when the signal from the PC (video card) is out of the horizontal or vertical frequency range of the monitor. See the ‘Specifications’ section and configure your monitor again.

• Do you see a “SELF DIAGNOSTICS” message on the screen? This message appears when the signal cable between your PC and your monitor is not connected. Check the signal cable and try again.

If your screen is flickering, try these solutions:

• Is the vertical frequency less than 70Hz or is your monitor set to the interlaced mode? Set the vertical frequency to 72Hz or higher, and consult the video card user manual for instructions on converting to a non-interlaced mode. You can typically set this option under the Display icon of the Control Panel.

• Do you have any magnetic material such as an adapter or high-voltage line near your monitor? Remove magnetic sources, such as power adapters, speakers, or high-voltage lines, away from the monitor.

• Do you hear a “~ding” sound while the monitor is flickering? Use the normal degaussing function. This function clears the screen and reduces any screen blur that may occur due to the surrounding magnetic field. The screen may flicker for about 5 seconds, accompanied by a “~ding” sound.

If the screen color is not normal, check the following points:

• Do you see basic discoloration (16 colors)? Set the color depth to 256 colors or higher. Use ‘Control Panel’ -> ‘Display’ -> ‘Settings’ -> ‘Color Palette’.

• Is the screen color unstable or monochrome? Check the connection of the signal cable. Or, pull out the video card of the PC and insert it again.

• Do you see black dots on the screen? This is due to a small amount of foreign or abnormally fluorescent material that became fastened on the mask during manufacturing. It will not affect product performance.

• Do you see a partial blurring on the screen? This happens due to interference from surrounding magnetic fields, as created when speakers, steel structures, or high-voltage lines are placed near the monitor. Remove any such materials from the immediate vicinity and use the DEGAUSS icon on the screen adjustment menu to fix the screen.

If you see an after-image on the screen:

If you see the after-image even when you turn off the monitor, a premature aging of the monitor pixels may cause the prolonged display of a single image on the screen. Be sure to use a screen saver to maximize the service life of the monitor.

If you see waves on the screen:

If you see a wave directly on the screen, this occurs in inverse proportion to the screen focus, which can be caused by a particular frequency or video card. Brighten the screen and use the ‘MOIRE’ icon on the screen adjustment menu to adjust the screen.
