MT-VIKI USB 3.0 & USB-C to Dual HDMI Multi-Monitor Adapter for Extended Display, 4K@30Hz + 1080P@60Hz Dual Screen Splitter, Driver Required for Windows & Mac Laptops

This MT-VIKI USB multi-display adapter acts as an external graphics card to expand your laptops display capacity via USB 3.0 or USB-C port, supporting dual-monitor mirror copy or extended independent screen mode to greatly boost multi-tasking efficiency for document editing, stock monitoring and graphic design work.

Equipped with a detachable 2-in-1 connecting cable, it eliminates the need for extra conversion adapters, seamlessly matching traditional USB-A desktops and thin Type-C ultrabooks. Two HDMI ports output different resolutions: the main port supports 4K@30Hz ultra HD fine graphics, while the secondary port outputs fluid 1080P@60P full HD images with lossless stereo audio sync.

The all-metal aluminum housing speeds up heat dissipation during long-time continuous operation and blocks electromagnetic interference to avoid screen flicker, color banding and frame drop. Important note: This device is not plug-and-play; users must download and install the official dedicated display driver before connection to activate multi-screen function.

It has clear system limits: Windows fully supports extended dual independent screens, while Mac OS only supports mirror mode due to system restrictions. Not compatible with Linux, TV boxes, iOS mobile devices, and cannot play HDCP encrypted streaming media like Netflix, Hulu.

Perfect for financial multi-monitor stock work, graphic design dual-screen editing, office conference multi-screen presentation and portable laptop external dual-display home viewing scenarios.
