  To correct an incorrect display image on your LG Monitor, first, press the AUTO button to automatically adjust the image. If the image position is still incorrect, use the H position and V position icons in the on-screen display to fine-tune it. If you see vertical bars or stripes, use the CLOCK icon in the on-screen display to decrease them. For horizontal noise or unclear characters, use the PHASE icon in the on-screen display to minimize the horizontal bars. Also, check your computer's display settings in Control Panel and ensure the resolution is set to the recommended value and the color setting is higher than 24 bits (true color).
