  If nothing is displayed on your LG Monitor screen, try the following: * Ensure the power cord is correctly plugged into the power outlet. * Check the power indicator. * Verify that the connected input is enabled via Menu > Input. * If the monitor is in power-saving mode, move the mouse or press any key on the keyboard. * Confirm that the computer is turned on. * Check the cable and reconnect if the signal cable between the PC and the monitor is missing or disconnected. * If signals transferred from the PC (video card) are out of the horizontal or vertical frequency range of the monitor, set the appropriate frequency according to the "Product Specification" section of this manual.

  If your LG Monitor screen retains an image, it may be due to displaying a still image for a prolonged time, which can cause damage. Use a screen saver to protect the screen when using the monitor for a prolonged period of time.

  If the display color is abnormal on your LG Monitor, here are a few things you can try: * Set the color to 24 bit (true color) or higher by going to Control Panel > Display > Settings > Color Quality in Windows. * Check if the signal cable is connected properly; try reconnecting the cable or reinserting the PC's video card. Note that pixilated spots (red, green, blue, white, or black) may appear on the screen. This is not an error and is unrelated to the monitor's performance.
