## Long description

The Lenovo USB 3 to DP Adapter (USB graphics adapter Lenovo 4X90J31021) delivers combined video and audio over a single USB port to a DisplayPort monitor, supporting up to 3840 x 2160 at 30 Hz. The compact black adapter is bus-powered via USB and is backward compatible with lower-resolution QHD and HD displays. It is suitable for adding DP output to an existing PC or for connecting conference room displays and digital signage without an external power supply.
Advantages
The adapter provides high-quality video with low latency and supports resolutions up to 4K (3840 x 2160@30Hz). It is USB bus powered so no external power adapter is required, and multiple units can be used to connect up to six additional displays (one adapter per monitor). The device includes integrated DisplayPort audio and is compatible with older USB 2.0 ports, although performance above 1080p on USB 2.0 is generally limited.
Suitable for
 Adding a DisplayPort monitor to a PC or laptop without native DP output
 Connecting conference room displays and digital signage
 Extending desktop workspace with multiple USB-driven monitors (up to 6 adapters)

How to use
Plug the adapter into an available USB port on the host computer, connect a DisplayPort cable from the adapter to the DP input on the monitor, and allow the operating system to detect and install any necessary drivers. Configure display settings in the OS to extend or mirror the desktop and select the desired resolution up to 3840 x 2160@30Hz. If connecting multiple adapters, install one adapter per monitor and configure each display in the system display settings.
Usage recommendations
For best performance at resolutions above 1080p, use a USB 3.0 or higher port on the host. While the adapter is backward compatible with USB 2.0, expect reduced performance and limited resolution capability when using USB 2.0. Use high-quality DisplayPort cables for reliable 4K output and ensure the host GPU and drivers support multiple external displays when connecting several adapters.
