6. Maintenance

To ensure the longevity and optimal performance of your monitor, follow these maintenance guidelines:

• Power Off When Not in Use: Turn off the monitor when not in use for extended periods to save energy and prolong its lifespan.

7. Troubleshooting

If you encounter issues with your monitor, refer to the following common solutions:

• No Power: Check if the power cord is securely connected to both the monitor and the power outlet. Ensure the power adapter is functioning correctly.
• No Signal: Verify that the video cable (DP or HDMI) is correctly connected to both the monitor and your computer/device. Ensure the correct input source is selected in the OSD menu.
• Flickering Screen: This can sometimes occur with Adaptive Sync enabled. Try disabling Adaptive Sync in the OSD or your graphics card settings. Ensure your graphics drivers are up to date. A user review mentioned restarting the PC with the monitor plugged in as a fix for flickering.
• Ghosting/Motion Blur: Adjust the response time setting in the OSD menu (e.g., to 'Fast' or 'Fastest'). Note that some settings may introduce inverse ghosting.
• Image Distortion/Incorrect Colors: Reset the monitor to factory settings via the OSD menu. Check your graphics card settings for color profiles.
