  If the screen color on your LG Monitor looks abnormal, first, set the number of colors to more than 24 bits (true color) via Control Panel - Display - Settings - Color Table menu in Windows. Next, check the signal cable's connection and re-insert the PC video card. Note that several pixels (red, green, white or black color) may appear on the screen, which can be attributable to the unique characteristics of the LCD panel and not a malfunction.

  If the screen image on your LG Monitor looks abnormal, and you're using a D-Sub analog signal, press the "AUTO" button on the remote to automatically optimize the screen. If it's still not right, go to [PICTURE] - [Screen] - [Position] in the OSD menu. Also, check that your video card resolution and frequency are supported; if the frequency is too high, set it to the recommended resolution in the Control Panel "Display" settings. Ensure the correct input signal is connected to the appropriate port.

Why does after-image appear on my LG Monitor?

  If you see an after-image on your LG Monitor, and you've been displaying a fixed image for a long time, the pixels may be wearing out. Try using the screen-saver function. Also, displaying a dark image after a high-contrast image can cause temporary image sticking, which is normal for LCD screens.
