Overview

The Monoprice Select Series USB-C to Mini DisplayPort Adapter (Model 124273) provides a simple way to connect a USB-C-equipped laptop or tablet to an external display with a Mini DisplayPort input. It supports resolutions up to 3840x2160 at 60Hz, making it suitable for 4K monitors and displays where crisp image quality is important for tasks like photo editing, design work, or multi-window productivity. The adapter works out of the box with no driver installation required, using the DisplayPort Alt Mode built into USB-C and Thunderbolt 3/4 ports.

Its compact form factor makes the adapter easy to slip into a laptop bag for on-the-go presentations or external monitor setups. The male USB-C connector plugs into the host device, while the female Mini DisplayPort port accepts a standard Mini DisplayPort cable running to your monitor. For users with Mini DisplayPort displays—common among older Apple Cinema Displays and various Dell and ASUS monitors—this adapter provides a clean, reliable connection path from modern USB-C laptops without bulky hubs or docking stations.
