Attaching the Monitor to Your Laptop

Connecting the Monitor
The Laptomo monitor supports multiple connection methods for video and power. Choose the method that best suits your laptop's ports.
- USB-C Connection (Full Function): If your laptop has a full-featured USB-C port (supporting video and power delivery), connect one USB-C to USB-C cable from your laptop to each monitor's USB-C port. This provides both video signal and power.
- HDMI + USB-A Connection: If your laptop has an HDMI port and a USB-A port, connect one HDMI to USB-C cable for video and one USB-A to USB-C cable for power to each monitor.
- Power Requirement: When using an HDMI connection, ensure a separate USB-A to USB-C cable is connected to the same extended screen for power.
- Plug & Play: Once connected, the monitors should be automatically detected by your operating system. You may need to adjust display settings in your OS.
