5. Maintenance

5.1. Cleaning the Monitor

Always unplug the monitor before cleaning.
Use a soft, lint-free cloth slightly dampened with water or a mild, non-abrasive screen cleaner.
Do not spray cleaner directly onto the screen. Apply it to the cloth first.
Avoid using benzene, thinner, ammonia-based cleaners, or abrasive materials, as these can damage the screen surface.
Wipe the screen gently to avoid scratching the matte finish.

5.2. General Care

Keep the monitor away from direct sunlight, excessive heat, or humidity.
Ensure proper ventilation around the monitor to prevent overheating.
Avoid placing heavy objects on the monitor or its cables.

6. Troubleshooting

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

Problem	Possible Solution
No image on screen	Ensure the power cable is securely connected to the monitor and a power outlet. Verify the video cable (DP/HDMI) is properly connected to both the monitor and your computer. Check if the correct input source is selected in the OSD menu. Ensure your computer is powered on and not in sleep mode.
Screen tearing or stuttering	Enable Adaptive Sync (FreeSync/G-Sync Compatible) in the monitor's OSD and your graphics card control panel. Ensure your graphics card drivers are up to date. Check that your game or application is running at a frame rate within the monitor's refresh rate range.
Poor image quality/colors	Adjust brightness, contrast, and color settings in the OSD menu. Ensure your graphics card is outputting the native resolution (3440x1440) and desired refresh rate. Consider calibrating the monitor for accurate colors.
Monitor not reaching 165Hz (or 180Hz)	Ensure you are using a DisplayPort 1.4 cable. HDMI 2.0 is limited to 100Hz at 3440x1440. Check your graphics card settings in your operating system to set the refresh rate. Update your graphics card drivers.
Physical defect (e.g., hair inside screen)	If a physical defect is present upon arrival, contact KTC customer support immediately.

8. User Tips

Higher Refresh Rate: Many users report that this monitor can achieve 180Hz refresh rate, despite being advertised as 165Hz. Check your display settings to see if this option is available for an even smoother experience.
External Speakers Recommended: The monitor does not have built-in speakers. Plan to use headphones or external speakers for audio.
Optimal for PC Gaming: While versatile, this ultrawide monitor is best suited for PC gaming and productivity due to its 21:9 aspect ratio. For console gaming (e.g., PS5), a 16:9 monitor might offer a more native full-screen experience without black bars.
Color Calibration: For the most accurate and vibrant colors, consider performing a color calibration after initial setup to match your personal preferences.

9. Warranty and Support

For warranty information, technical support, or service inquiries, please refer to the official KTC website or contact your retailer. Ensure you have your monitor's model number (H34S18S) and serial number ready when contacting support.
