Read the instructions on the link Adjusting the Screen Resolution on the DVD, and then select the correct resolution, refresh rate and make adjustments based on these instructions. How do you use a VGA extension cable? Remove the extension cable for the test. Is the image now in focus? If not, optimize the image by working through the instructions in the Adjusting the refresh rate section on the link Adjusting the Screen Resolution. It is normal for blurring to occur due to conduction losses in extension cables. You can minimize these losses by using an extension cable with better conduction quality or with a built-in booster. Does the blurring only occur at resolutions lower than the native (maximum) resolution? Read the instructions on the link Adjusting the Screen Resolution on the DVD. Select the native resolution.

One of several pixels is permanently black, one or more pixels are permanently white, one or more pixels are permanently red, green, blue or another color. • Clean the LCD screen. • Cycle power on-off. • These are pixels that are permanently on or off and is a natural defect that occurs in LCD technology.

You are running the monitor at its native resolution, but the image is still distorted. Images from different input sources may appear distorted or stretched on the monitor running at its native resolution. To have the optimal display performance of each type of input sources, you can use the Aspect Ratio function to set a proper aspect ratio for the input sources. See Aspect Ratio on page 36 for details. The image is displaced in one direction.

54 Troubleshooting Need more help? If your problems remain after checking this manual, please contact your place of purchase or e-mail us at: [email protected]. The light sensor of the monitor does not work well. The light sensor is located at the front bottom of the monitor. Please check: • If the Eye Protect function is set to ON. Check Ergonomics > Eye Protect. • If there are any obstacles in front of the sensor that keep the sensor from detecting the light properly. • If there are any objects or clothing in bright colors in front of the sensor. Bright colors (especially white and fluorescent colors) reflect light and the sensor cannot detect the main light sources. The Eco sensor of the monitor does not work well. • The Eco sensor is located at the front bottom of the monitor. Check if there are any obstacles in front of the sensor that keep the sensor from detecting your presence properly. • The colors and the materials of your clothes may affect the detection. Adjust the sensor range if needed. See Sensor Range on page 45 for more information. • Adjust the distance between you and the monitor. If none of the proceeding actions works, it is probably because the materials of your clothes are unique and cannot be detected by the Eco sensor. Please be noted that this is neither a manufacturing defect nor is the sensor damaged. You should turn off the Eco sensor for now in Eco > Eco Sensor.
