Types of HDMI Connectors

Types of HDMI Connectors

HDMI connectors let you link your favorite devices to displays or TVs for streaming your video and audio. There’s a good chance you’re using one of several types designed to fit different devices and needs.

Type A Connector

Type A HDMI is your standard go-to. Also known as the standard HDMI connector, it’s what you’ll typically find on the back of your TV, gaming console, or Blu-ray player. Think of it as the USB Type-A of video connections—super common and pretty much everywhere. With its 19 pins, the male connector measures 13.9mm x 4.45mm, meaning it’s fairly compact but still substantial enough to handle most of your entertainment needs.

Type C Connector

The Type C HDMI, or mini HDMI, is the sleeker, smaller sibling to Type A. You’ll find this type on portable devices where space is at a premium, like DSLR cameras, high-definition camcorders, and some tablets. Mini in size but not in power, this connector maintains the 19-pin configuration – just in a more compact form at 10.42mm x 2.42mm.

Type D Connector

Now, if you’re dealing with even smaller devices, like mobile phones or action cams, say hello to the Type D HDMI or micro HDMI. It’s the tiniest in the family, designed to fit the confined spaces of hand-held gadgets without compromising on the high-definition experience. Picture the mini connector then shrink it down to a mere 6.4mm x 2.8mm frame.

Type E Connector

Not as commonly seen in consumer electronics, the Type E HDMI, steps into the spotlight for automotive and industrial applications. It’s built to withstand the rigors of moving vehicles and outdoor conditions, sporting a locking tab to keep the cable firmly in place and dirt out. Consider Type E the fortified cousin, ensuring your in-vehicle infotainment and other rugged systems stay connected no matter the bumps on the road.

HDMI and Other Interfaces

When you’re setting up your devices, understanding how HDMI interacts with other types of connections is crucial. Let’s clear up how HDMI compares with other common interfaces you might encounter.


DVI (Digital Visual Interface) is an older type of connection that’s mainly used for computer monitors. Unlike HDMI, which carries audio and video signals, DVI connections are video only. You can often adapt DVI to HDMI with a simple cable, but keep in mind you won’t get audio through DVI.


USB-C ports are now common and can carry HDMI signals with the right adapter or cable. This means you can use a USB-C port to connect to an HDMI display, but you’ll need a cable that has a USB-C connector on one end and an HDMI connector on the other. It’s a convenient option since USB-C also supports data transfer and power delivery.

DisplayPort vs. HDMI

DisplayPort is similar to HDMI in that it also supports high-definition audio and video, but it’s often favored for PC monitors. One advantage of DisplayPort is its ability to daisy chain multiple monitors together off a single connection from your source. Although HDMI cables have their own strengths such as widespread compatibility, especially with TVs.

Improving Your HDMI Experience

When you’re looking to get the most out of your HDMI usage, whether on your desktop, laptop, or other electronics, a few simple improvements can enhance image quality and sound. Here are some practical tips:

  • Check Your HDMI Cables: An obvious but often overlooked aspect is the quality of your HDMI cable. Make sure it’s not frayed or damaged. If you need to extend your setup, opt for a high-quality cable to prevent signal degradation.

  • Correct Aspect Ratio: Ensure your device’s aspect ratio matches your display. You can usually tweak these settings with your remote control to get the full, crisp image you’re looking for without any annoying cropping or stretching.

  • Optimize Sound Settings: Your HDMI cable carries both video and audio signals. Dive into your device’s sound settings to ensure you’re getting the best audio experience. Consider a sound check or a calibration tool if your device supports it.

  • Connect Multiple Devices: To fully leverage the potential of your HDMI ports, especially if you want to switch between gaming, streaming, and other media without constantly plugging and unplugging cables, consider an HDMI switch. It’s a neat way to manage multiple HDMI connections through one port.

Remember, every device is a little different, so check your manual or online resources specific to your electronics for the best results. With these tweaks, you’ll be enjoying your HD content as it’s meant to be, with minimal hassle.
