Dual 4K DisplayFor devices supporting DP Alt Mode 1.4, output content to two displays simultaneously at resolutions up to 4K@60Hz. If your device only supports DP Alt Mode 1.2, the maximum resolution for dual displays is 4K@30Hz. With this Reborn USB C to Dual HDMI Adapter, you can enjoy vivid visuals on dual screens. Its a 4 in 1 USB C Hub Multiport Adapter featuring dual HDMI ports, a USB 3.0 port, and 100W PD charging functionality. Ideal for MacBook, Lenovo Yoga, Thinkpad, XPS, etc., macOS only supports Single-Stream Transport (SST) mode for this adapter. Important Note for macOS UsersThis HDMI splitter for dual monitors doesn't support MST on macOS. Due to system constraints, it only works in mirror mode, displaying the same content on both monitors, and can't extend two distinct screens. Before buying, verify that your device's USB-C port supports video output or DP Alt mode (look for the DP logo near the port). Unsure? Contact our customer service for help.
