Maintenance
Cleaning the Screen
To clean the monitor screen, gently wipe it with a soft, lint-free cloth. For more persistent smudges, lightly dampen the cloth with water or a specialized non-abrasive screen cleaner. Avoid using harsh chemicals, alcohol-based cleaners, or abrasive materials, as these can damage the screen surface.
General Care
Keep the monitor in a clean, dry, and well-ventilated environment. Protect it from extreme temperatures, direct sunlight, and high humidity. Do not place heavy objects on the monitor or block its ventilation openings. Handle the monitor with care to avoid physical damage.
Troubleshooting
This section addresses common issues you might encounter. If your problem is not listed or persists, please contact customer support.
Issue: Touch Function Not Working
Symptom: The touchscreen is unresponsive or inaccurate.
Solution:
- Ensure the USB A-B cable is securely connected from the monitor's USB-B Touch Port to an available USB port on your computer. This connection is mandatory for touch functionality.
- For Windows users: Navigate to Control Panel > Hardware and Sound > Tablet PC Settings. Click "Calibrate" and follow the on-screen prompts to select the 27-inch touchscreen monitor.
- Note that certain devices and platforms (e.g., PS5, Xbox, Steam Deck, Nintendo Switch, Fire TV stick, and some Apple products) do not support touch functionality due to their operating system or hardware limitations.
Issue: Cursor Moves Erratically When Touching Screen (Windows)
Symptom: Touching the monitor causes the cursor on your primary PC screen to move instead of interacting with the touchscreen itself.
Solution: This indicates the touch input is incorrectly mapped to another display. To correct this, go to Control Panel > Hardware and Sound > Tablet PC Settings. Click "Calibrate" and ensure you select the correct 27-inch touchscreen monitor when prompted to identify your touch display.
Issue: Unable to Set Desired Resolution (e.g., 4K)
Symptom: The monitor does not display at its native 4K (3840x2160) resolution, or the option is unavailable.
Solution: Right-click on your desktop and select "Display Settings" (Windows) or "System Preferences > Displays" (macOS). Ensure the monitor is detected. Under "Multiple Displays" or similar settings, select the Pisichen monitor and choose the recommended resolution of 3840x2160 from the resolution options. Also, ensure your graphics card and video cable (HDMI or DisplayPort) support 4K resolution at 60Hz.
Issue: Power Adapter Does Not Fit
Symptom: The provided AC power adapter connector does not fit into the monitor's DC Power Port.
Solution: Verify that you are using the power adapter specifically supplied with your Pisichen monitor. If the issue persists, there might be a manufacturing defect; please contact customer support for assistance.
Issue: VESA Mount Screw Mismatch
Symptom: Standard M4 VESA mounting screws do not fit the monitor's VESA holes.
Solution: This monitor requires M4 fine thread screws (0.5mm pitch) for VESA mounting. Standard M4 screws typically have a 0.7mm pitch and are not compatible. Ensure you use the correct fine thread screws to avoid damaging the monitor's mounting points.
