- USB-C Connection (Recommended for single cable solution):
If your laptop or device has a full-featured USB-C port (supporting Thunderbolt 3/4 or USB-C 3.1/3.2 DisplayPort Alt Mode), connect a USB-C to USB-C cable from your device to the monitor's USB-C port. This single cable can provide both power and video signal.
Note: Ensure your device's USB-C port supports video output and power delivery. If not, external power may be required.
- HDMI Connection (Requires external power):
Connect an HDMI cable from your device to the monitor's Mini HDMI port. When using HDMI, you must also connect the monitor to a power source using the provided power adapter and a USB-C cable for power delivery.
- Power Supply:
For stable display, especially when using HDMI or if your USB-C port does not provide sufficient power, connect the monitor to the power adapter using a USB-C cable.
3. Driver Installation
The COOLHOOD Dual Portable Monitor is designed for plug-and-play functionality. No additional drivers or software installation is typically required for Windows or macOS systems when connected via a full-featured USB-C port.

Operating Instructions
1. Powering On/Off
Press and hold the Power/Back Button located on the side of the monitor to turn it on or off.
2. Menu Navigation
Use the Pulley Button to navigate through the On-Screen Display (OSD) menu. Press the Pulley Button to enter the menu, scroll up/down to select options, and press again to confirm. The Power/Back Button can be used to go back to the previous menu or exit the OSD.
Each of the two screens has its own independent menu for configuration, allowing for separate adjustments of brightness, contrast, color settings, and more.
3. Display Modes
The monitor supports various display modes to suit your workflow:
- Mirror Mode: Both screens display the same content as your primary device.
- Extend Mode: Each screen displays different content, extending your desktop workspace.
- Link Mode: The two portable screens can be combined to act as one larger, continuous display.

You can typically switch between these modes through your operating system's display settings (e.g., Windows Display Settings or macOS System Preferences > Displays).
VESA Mounting
The COOLHOOD Dual Portable Monitor features VESA mounting holes (75mm x 75mm) on the back of each screen. This allows you to mount the monitor on compatible VESA arms or stands, providing more flexibility for your workspace setup and saving desk space.

Maintenance
Cleaning the Monitor
- Always power off the monitor and disconnect it from the power source before cleaning.
- Use a soft, lint-free cloth lightly dampened with water or a non-abrasive screen cleaner.
