4.2 Connecting to Devices
The ZSUS portable monitor offers versatile connectivity options for various devices. For optimal performance, especially with demanding applications or when using a single Type-C cable for both power and display, it is recommended to use the provided power adapter.

4.2.1 Using Type-C (Full Function)
Connect one end of the Type-C cable to the Type-C Full Function Interface (E) on the monitor and the other end to a compatible Type-C port on your device (e.g., laptop, smartphone, Nintendo Switch). This single cable can transmit both video signal and power, provided your device's Type-C port supports DisplayPort Alternate Mode and sufficient power output. If the device cannot supply enough power, connect the power adapter to the Type-C Power Port (F) on the monitor.

4.2.2 Using Mini HDMI
Connect one end of the provided HD cable (Mini HDMI) to the Mini HDMI port (D) on the monitor and the other end (standard HDMI) to your device (e.g., laptop, gaming console, TV box). When using HDMI, you must connect the power adapter to the Type-C Power Port (F) on the monitor for power.
4.2.3 Powering the Monitor
Connect the provided power adapter to the Type-C Power Port (F) on the monitor. This ensures stable power delivery, especially when using HDMI or if your device's Type-C port does not provide sufficient power.
