3.2 Connecting to Your Laptop

The KEFEYA S2 PRO MAX supports two primary connection methods:

• Option 1: Full-featured USB-C (Video & Power)
  If your laptop has two full-featured USB-C ports (supporting both video and power), connect each portable screen directly to a USB-C port on your laptop using the provided Type-C to Type-C cables. This is the simplest plug-and-play method.
• Option 2: HDMI (Video Only) + USB-A (Power Only)
  If your laptop does not have enough full-featured USB-C ports, you can use a combination of HDMI and USB-A. For each screen, connect the HDMI to Type-C cable for video and a USB-A to USB-C cable for power. Ensure the USB-C end of the HDMI cable connects to the port marked "HDMI" on the portable monitor.

Important Note for M1/M2/M3 MacBook Users: These MacBooks do not directly support triple screen output. A customized H6 video signal conversion hub (B0FRRVFN25, sold separately) is required to enable the full triple screen functionality. Without the hub, only one external screen may be supported.
