      2. It is difficult to connect an angle plug earphone or a peripheral device, so please use a straight type plug.
  • Most of our monitors are Plug-and-Play compliant, meaning that when you plug the monitor in to your computer, it will automatically work without additional setup. This is the case if you have only one monitor plugged in to your computer.

    If you have multiple devices plugged in to your monitor, use the Input button to switch between them. The Input button is located on the button bezel, most often found on the bottom of the monitor, either in the center or on the right side.

    If you have multiple monitors, you may need to configure your Operating System (on your computer) to correctly display on the additional monitor.

    • General Steps (should work with all Windows versions XP and newer):

      1. Right-click an open area on your desktop.
      2. Choose Screen Resolution from the menu that appears.
      3. The Screen Resolution menu provides several options to adjust connected monitors.
      4. Click Identify (pointed at by the top-right arrow) to display large numbers on each connected monitor corresponding to the numbers you see in this menu.
      5. In the Multiple Displays section, you have a few options.
        • Mirror/Duplicate Display will show the same screen on both monitors. This is a good option if presenting to others because you can control the computer screen while they view your actions on a different, possibly larger screen.
        • Extend Display will make the second monitor an extension of the first, meaning you will be able to view different items on each display. Simply drag a window from one screen to the next.
        • You may have options to show the desktop only on certain screens. If you use this option, whichever screen you choose will be the only one that receives a signal. This means the other monitor will either sleep, or display a no signal message. Choose one of the other options for the best experience.
      6. Click on the image corresponding to your monitor to make changes.
      7. If you have no image or a distorted image on your monitor, adjusting the resolution to the optimal setting should fix it.
      8. For help with specific versions of windows, please visit the following links:
      9. If you were unable to connect your monitor, try the Troubleshooting section to diagnose the issue (Hint: Start with the Power Issues section).
  • Available settings, and buttons for accessing menus, will differ by model. Consult your user guide for specific instructions. A user guide should have come with your monitor, but you can also download it from the product support page.

    • Enter your model number into the search box at the top of the page.
    • Choose your monitor from the dropdown list that appears.
    • Choose Product Support.
    • Go to the Manuals & Documents section, then click the link under Owner's Manual for your preferred language.
  • The Dual Linkup feature allows two compatible portable devices--such as a computer, camera, phone, or Blu-ray player--to be connected to the monitor, and both can be viewed on the same screen simultaneously.

    Note: To use Dual Linkup, one device must be connected to the DisplayPort while the other is connected to either the HDMI or DVI port.

  • Multitasking doesn't have to mean shuffling back and forth between windows. With a single click, the 4-Screen Split feature divides the screen into as many as four customizable segments, two-by-two. Now you can see four different windows at the same time.

    Note: Screen Split software runs on Windows Vista/7/8 and Mac OS.

    1. Cleaning the monitor

      Clean your monitor regularly to keep it at peak performance and to extend the product’s lifespan.

      - Before cleaning, turn the power off and disconnect the power cord and all other cables.
      - When the monitor is left unattended or unused for a long time, disconnect the power cord from the wall outlet to prevent possible damage from lightning or power surges.

    2. Screen, frame, cabinet, and stand

      To remove dust or light dirt, wipe the surface with a dry, clean, and soft cloth.
      To remove major dirt, wipe the surface with a soft cloth dampened in clean water or a diluted mild detergent. Then wipe immediately with a dry cloth.

      - Do not push, rub, or hit the surface with your fingernail or a sharp object, as this may result in scratches on the screen and image distortions.
      - Do not use any chemicals, such as waxes, benzene, alcohol, thinners, insecticides, air fresheners, or lubricants, as these may damage the screen’s finish and cause discoloration.
      - Do not spray liquid onto the surface. If water enters the TV, it may result in fire, electric shock, or malfunction.

    3. Power cord

      Remove the accumulated dust or dirt on the power cord regularly with a damp cloth while the cord is unplugged from the monitor and the wall.

  • Monitor drivers shouldn't be necessary, as all of our LG monitors are Plug-and-Play compliant. It is more likely that if your issue is driver related, the driver for your computer's video card will resolve it (these can be found at the computer or video card manufacturer's website). If you feel a monitor driver will help, visit the product support page for your model to check for available software. Otherwise, refer to the Troubleshooting section.

    To find the product support page:

    • Enter your model number into the search box at the top of the page.
    • Choose your monitor from the dropdown list that appears.
    • Choose Product Support.
    • If it exists for your model, go to the Software Update section, then click the software link.
