Compatibility & Fit
Works from a USB Port
Unlike USB-C video adapters, this adapter does not rely on DisplayPort Alt Mode: it adds a display through a USB 3.0 port, so it suits desktops and notebooks without a spare video output.
Driver Software
USB display adapters of this kind use driver software on the host PC. Check Lenovo Support for the current driver for your operating system before deployment.
Native Video Outputs
If your laptop has a video-capable USB-C port, the Lenovo USB-C to DisplayPort Adapter (4X90Q93303) uses that port's native video output instead.
