USB 3.0 is the standard thin rectangular USB port called a Type-A connection.

Be careful, not all Type-A connections are 3.0. Look for a USB icon (trident tipped with a circle, triangle, and square) with the letters SS (SuperSpeed). If you don’t see an icon, look in the port, you should see blue.

What to expect

A USB 3.0 connection has a maximum bandwidth of 5 Gbps. That should be more than enough to drive multiple displays, and peripherals. It is worth noting that a USB 3.0 port will not supply charging power to your laptop, so you’ll still need your own power cord.

The newest connection type, USB Type-C (USB-C) is a thin oval-shaped port.

This one can get tricky. Just looking at the shape of the port might not be enough, as not all USB-C ports are the same. Just because a laptop has a USB-C port, doesn’t mean that the port supports video and charging.

What to expect

USB-C ports are designed to deliver a lot of performance. Depending on your computer, a USB-C port is capable of charging--so you don’t need an extra power cord--and data-transfer speeds between 10 Gbps and 40 Gbps. That’s more than enough power to drive extra screens and peripherals.

It’s worth noting that not all USB-C ports support video (Alt Mode) or charging (Power Delivery). Some USB-C ports support data transfer only, so you'll want to double-check with your computer manufacturer.

The newest connection type, Thunderbolt 3 is a thin oval-shaped port.

This one can get tricky. Just looking at the shape of the port might not be enough, as Thunderbolt 3 ports share the same Type-C connection as USB-C. Look for the Thunderbolt icon (lightning-bolt tipped with an arrow). If you see a trident topped with a circle, triangle, and square it’s a USB-C port. If no icons are present, you may need to check with the manufacturer.

What to expect

With Thunderbolt 3, you always know you’re getting incredibly fast 40 Gbps data-transfer speeds. That’s going to give you enough power to drive even the most high-end monitors and external drives, not to mention any other peripheral you need to connect.

The most common video connection, HDMI carries a high-resolution digital video signal with support for audio. HDMI can be converted to DVI by using a separate adapter, or specialized cable.

A connection common on high-definition monitors, DisplayPort carries a high-resolution digital video signal with support for audio.

DVI or Digital Video Interface supports resolution of up to 1900x1200. Look for a large rectangular port with a grid pattern and a “plus” shaped pinhole.

Remember, DVI is video only. You’ll still need to account for audio.

The oldest of the video connections, VGA is a trapezoid shaped port capable of carrying an analog signal up to 1920x1200.

Remember, VGA is video only. You’ll still need to account for audio.

USB 3.0 appears as a horizontal port with the bottom portion dedicated to pin connectors.

You can usually distinguish it port by observing the port being blue, as well as USB 3.0 iconography
