Best Mini DisplayPort to DisplayPort Adapters: Connect Your Mac to Any Monitor
Do you find your monitor options limited with your older Mac? It doesn’t have to be that way! With a Mini DisplayPort (Mini DP) to DisplayPort (DP) adapter you can simply and affordably connect your MacBook, iMac, or other Mini DP device to the latest monitors.
In this guide, we’ll cover everything you need to know about these adapters, including recommendations for the best ones on the market.
What is a Mini DisplayPort to DisplayPort Adapter?
A Mini DisplayPort to DisplayPort adapter is a small dongle that converts the signal from your device’s Mini DP output into a standard DisplayPort signal that most monitors use.
Why would you need one? Many Apple products, particularly those manufactured before 2016, like the MacBook Air and older MacBook Pro models, used Mini DisplayPort for video output. However, Apple transitioned to USB-C ports in newer models. If you have one of these older Macs and want to connect it to a monitor with a standard DisplayPort input, a Mini DP to DP adapter is needed.
This doesn’t just affect Macs. Some Windows PCs, even in 2025, also feature Mini DP ports. For example, the Gigabyte G5 features a Mini DP 1.2 port.
How Mini DP to DP Adapters Work
Mini DisplayPort to DisplayPort adapters are incredibly simple to use. They have a male Mini DisplayPort connector on one end, which plugs into your Mac, and a female DisplayPort connector on the other end, which connects to your monitor’s DP port.
The adapter is plug-and-play and handles the signal process conversion without the need for any driver installation.
Bandwidth and Resolution: Mini DP to DP adapters support high bandwidth, allowing for resolutions up to 4K@60Hz. This means that you can enjoy crystal-clear and detailed visuals on a 4K monitor with smooth 60 frames per second. This is enough for tasks like graphic design and video editing.
