USB-C Connection (Full Function):
If your device (laptop, smartphone) has a full-function USB-C port that supports video output (DisplayPort Alternate Mode) and power delivery, you can connect the monitor using a single USB-C to USB-C cable. This cable will provide power, video, and enable touchscreen functionality.
Note: Ensure your device's USB-C port supports video output. If not, you may need an additional power source for the monitor.
HDMI Connection:
Connect the monitor to your device (PC, laptop, gaming console) using the provided HDMI to Mini HDMI cable for video signal. For power, connect the monitor to a power source using the USB-A to USB-C cable and the power adapter, or another USB-C power source.
Note: Touchscreen functionality requires an additional USB connection (USB-A to USB-C) from the monitor to your device when using HDMI.
Powering the Monitor:
The monitor can be powered via USB-C from a compatible device or an external power adapter. Ensure sufficient power is supplied for stable operation, especially when using HDMI or if your USB-C source cannot provide enough power.

Use a soft, dry cloth to clean the monitor's casing. Do not use liquid cleaners directly on the casing.
Storage:
When not in use, store the monitor in a cool, dry place, away from direct sunlight and extreme temperatures. If transporting, use a protective sleeve or case to prevent scratches and damage.
Avoid Impact:
Protect the monitor from drops, impacts, and excessive pressure, especially on the screen, as this can cause permanent damage.

Problem	Possible Cause	Solution
