Mini Displayport comes with some of the features common to DisplayPorts. One of the most important features of DisplayPorts is audio and video transmission. Support for audio and video is what makes it possible to carry content from a computer to a monitor. Mini DisplayPorts become unique for almost the same features.
What is Mini DisplayPort?
You must have heard about DisplayPort, an audio visual digital interface, and mini DisplayPort is a miniature version of DisplayPort. Introduced by Apple in 2008, this port became common in all Apple computers like MacBook. But a few years later, mini DisplayPort saw a replacement in the form of USB-C connectors. You can also find mini DisplayPort in video cards and motherboards of brands like Microsoft, Asus, Lenovo and many others.
The mini DisplayPort supports resolutions up to 2560×1600 for the version DisplayPort 1.1a and 4096×2160 (4K) for the version DisplayPort 1.2. Using an adapter makes mini DisplayPort compatible with HDMI, VGA, and DVI interfaces. DisplayPort 1.2 technology has become popular for its support for multi-channel audio, uncompressed 4K video at 60Hz, and 3D stereo.
Mini Displayports are compatible with Thunderbolt devices and enable users to enjoy digital audio. Another feature is that mini DisplayPorts can be connected to the HDMI using a split cable. Its capability to connect to a USB port is the unique feature that is made possible by adapters.
Mini Displayport and Audio
A lot of users cloud the internet with this question – Does mini DisplayPort carry audio? The simple answer to this is yes, mini DisplayPort does carry sound and video. The mini DisplayPorts present on MacBook Pros manufactured before 2010 did not use to carry audio, but now they do in the latest versions.
Previously, the MacBook Pros, MacBooks etc, provided audio signal through Firewire, USB, and the audio line out port. This created issue for users who wanted to connect these devices to their HDTVs using a Mini DisplayPort to HDMI adapter.
A solution for this was the dual or triple-headed adapters that got video from Mini DisplayPort, power from a USB port, and audio from the optical-out port or the USB port. At the end is the HDMI connector that lets audio and video be transmitted over a single HDMI cable.
Mini DisplayPort to HDMI
Mini DisplayPort to HDMI supports audio. The HDMI connector can be connected to a monitor, and the USB and mini DisplayPort can be connected to a PC or Mac. When the connection is made, 2-channel analog audio passes to the HDMI connection, thus enabling the display to receive quality sound. The advantage here is that just a single HDMI cable is needed for this to happen.
So the good news is Mini DisplayPort does carry audio though this was not the case in previous versions of Apple devices like MacBooks. If you own an older device, you can use a Mini DisplayPort to HDMI adapter which would solve the compatibility issue.
