Maintenance
Cleaning the Monitor
To clean the monitor screen and casing:
- Turn off the monitor and unplug the power cord.
- Gently wipe the screen with a soft, lint-free cloth. For stubborn marks, lightly dampen the cloth with water or a mild, non-abrasive screen cleaner.
- Wipe the casing with a soft, dry cloth.
- Avoid using harsh chemicals, abrasive cleaners, or spraying liquids directly onto the screen or casing.
Troubleshooting
If you encounter issues with your monitor, refer to the following common problems and solutions:
- No Power: Ensure the power cable and AC/DC adapter are securely connected to both the monitor and a working power outlet.
- No Signal: Verify that the video cable (HDMI or DisplayPort) is correctly connected to both the monitor and your source device. Ensure the correct input source is selected in the OSD menu.
- Washed Out Colors (with HDR): If HDR is enabled on your connected device but set to Off in the monitor's OSD, colors may appear dull. Enable HDR in the monitor's OSD settings. Note that some OSD settings may be inaccessible when HDR is active.
- Image Flickering/Tearing: Ensure AMD FreeSync is enabled on both your monitor (via OSD) and your graphics card settings.
- Motion Artifacts: If you observe ghosting or artifacts during fast motion, check the "Response Time" setting in the OSD. Setting it to "Ultra Fast" may sometimes introduce artifacts; try "Advanced" instead.
- No Sound from Monitor Speakers: Check the audio output settings on your connected device and the monitor's OSD. Ensure external speakers/headphones are properly connected to the 3.5mm audio out port if used.
- Missing HDMI Cable: Please note that while a DisplayPort cable is often included, an HDMI cable may not always be part of the standard package.
