6. Connectivity Options
The S8PRO offers flexible connection methods depending on your laptop's ports:
6.1 Two Full-featured USB-C Ports
If your laptop has two full-featured USB-C ports, use two USB-C to USB-C cables to connect both screens. This provides video, audio, and power through a single cable per screen.
6.2 One Full-featured USB-C Port and HDMI/USB-A
If your laptop has one full-featured USB-C port, use a USB-C to USB-C cable for one monitor. For the second monitor, use an HDMI cable for video and a USB-A to USB-C cable for power and data.
6.3 Laptops Without Full-featured USB-C (Using H5-T Adapter)
For laptops lacking full-featured USB-C ports, an H5-T compatibility cable is provided. This adapter converts USB-A/C to video output. Connect the H5-T adapter along with an HDMI cable for video, and a USB-A to USB-C cable for power. An external power supply may be required for optimal performance.
