Image: Kwumsy S2 connection options. This image details three different ways to connect the Kwumsy S2 to a laptop, depending on the available ports.
- Option 1: Two Full-Featured Type-C Interfaces
Connect the S2 directly to your laptop using two USB-C to USB-C cables. This is the simplest method if your laptop has two full-featured Type-C ports. - Option 2: One Full-Featured Type-C and One HDMI + USB-A Interface
Connect one screen with a USB-C to USB-C cable to a full-featured Type-C port on your laptop. Connect the second screen using a USB-C to HDMI cable (for video signal) and a USB-C to USB-A cable (for power) to your laptop. - Option 3: Two HDMI + Two USB-A Interfaces
Connect each screen to your laptop using a USB-C to HDMI cable (for video signal) and a USB-C to USB-A cable (for power). This option requires two HDMI ports and two USB-A ports on your laptop.
Important Note: If the power supplied by your laptop's interface is insufficient for the screens, please use an external 5V/2A adapter to power the monitors.

4.3 Powering the Device
The Kwumsy S2 typically draws power from your laptop via the connected USB-C cables. For optimal performance or if your laptop's power output is limited, an external power source can be used.
- Laptop Charging: If you connect an external 65W power adapter to a full-featured Type-C port on the S2, the monitor can provide Power Delivery (PD) to charge your laptop.

7. Maintenance
To ensure the longevity and optimal performance of your Kwumsy S2 monitor, follow these maintenance guidelines:
- Cleaning: Use a soft, lint-free cloth to gently wipe the screen surfaces. For stubborn smudges, slightly dampen the cloth with water or a screen-safe cleaning solution. Avoid harsh chemicals or abrasive materials.
- Handling: Always handle the monitor extender with care. Avoid dropping it or subjecting it to strong impacts.
- Storage: When not in use, store the monitor in the provided travel bag to protect it from dust and scratches.
- Temperature: Avoid exposing the device to extreme temperatures or direct sunlight for prolonged periods.
8. Troubleshooting
If you encounter issues with your Kwumsy S2 monitor, refer to the following common problems and solutions:
- Only one monitor works:
This is typically due to the laptop's video output capabilities. Ensure your laptop supports two video signals output. Check all cable connections to ensure they are secure and correctly plugged into full-featured Type-C ports or the appropriate HDMI/USB-A combinations. Refer to Section 4.2 for connection options. - No display on either screen:
Verify that the monitors are receiving power. Check all cable connections between the S2 and your laptop. Ensure your laptop's display settings are configured to detect and extend to external monitors. - Screen blurry or incorrect resolution:
The native resolution of the screens is 1920x1080. Ensure your laptop's display settings are configured to output at this resolution for the external monitors. Adjust display scaling if text appears too small or large. - MacBook M1/M2 chip compatibility:
MacBook models with M1 or M2 chips are generally not compatible with using both external screens simultaneously due to their single external video signal output limitation. Only one screen may function. - Monitors flicker or disconnect intermittently:
This could indicate insufficient power. Ensure your laptop is adequately powered, or connect an external 5V/2A adapter to the S2 if needed. Check for loose cable connections.
