4. Troubleshooting
If you encounter issues with your KTC H24F7 monitor, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No image on screen | Power cable disconnected; Video cable disconnected or loose; Incorrect input source selected; Monitor is off. | Ensure power cable is securely connected and monitor is on. Check video cable connections (HDMI/DisplayPort) at both the monitor and computer. Press the input source button on the monitor to cycle through inputs. |
| Image flickering or tearing | Adaptive Sync not enabled; Graphics card driver issues; Faulty video cable. | Enable Adaptive Sync in the OSD menu and your graphics card control panel. Update graphics card drivers. Try a different video cable. If using DisplayPort 1, try DisplayPort 2 or HDMI if available, as some units may experience issues with specific ports. |
| Colors appear incorrect or washed out | Color settings incorrect; HDR not properly configured; Faulty video cable. | Adjust color settings (brightness, contrast, color temperature) in the OSD menu. Ensure HDR is enabled in both the OSD and your operating system for HDR content. Try a different video cable. |
| Monitor not reaching 240Hz | Graphics card limitations; Incorrect display settings in OS; Cable bandwidth limitations. | Ensure your graphics card supports 240Hz at 1080p. Verify display settings in your operating system (e.g., Windows Display Settings or NVIDIA/AMD control panel) are set to 240Hz. Use the provided HDMI cable or a certified DisplayPort 1.4 cable. |
| Stuck or dead pixels | Manufacturing defect. | A small number of stuck or dead pixels (typically 1-3) may be considered normal for LCD panels. If the issue is severe or persistent, contact customer support. |
