Understanding DisplayPort Alt Mode and Connecting Your MacBook Air to a Monitor

Are you looking for a reliable way to connect your MacBook Air to an external monitor via USB-C? If so, you're probably wondering if your Mac needs the DisplayPort Alt Mode function to make it work. In this article, we'll explore the answers to these questions and provide guidance on what to look for when buying a USB-C to USB-C connection that supports display port.

Firstly, let's clarify what DisplayPort Alt Mode is. In simple terms, it's a technology that allows USB-C ports to be used as an alternate mode for carrying DisplayPort signals. This means that your MacBook Air can use its Thunderbolt 3 (USB-C) ports to output video signals to an external monitor.

So, does your MacBook Air 2018 Retina version have the DisplayPort Alt Mode function? The answer is yes! Your Mac's Thunderbolt 3 ports support DisplayPort Alt Mode, which means you can connect your laptop to a monitor via USB-C.

When shopping for a USB-C to USB-C connection that supports display port, look for cables with the following specifications:

* USB-C on both ends (not USB-A or Micro-USB)

* Support for USB 3.1 Gen 2, which includes DisplayPort Alternate Mode

* A minimum bandwidth of 10 Gbps

You can also check the packaging or product description to ensure that the cable supports display port transmission.

Another important consideration is the type of monitor you're using. In your case, you have an HP EliteDisplay E273q 27-inch Monitor. Make sure that it's compatible with USB-C and has a DisplayPort interface.

Now, let's talk about the shipped-in charger cable that came with your MacBook Air. Unfortunately, this cable only supports charging and data transmission, but not video output. To connect your laptop to an external monitor, you'll need a dedicated USB-C to USB-C connection that supports display port.

In conclusion, connecting your MacBook Air to a monitor via DisplayPort is a great way to increase productivity and reduce heat generation on your Mac. By choosing the right cable and understanding the specifications, you can enjoy seamless video output from your laptop to an external monitor.
