外観の特徴

USB 3.0 は通常 Type-A と呼ばれる薄い長方形の形状をした、標準的な USB ポートです。

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.

性能

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.

外観の特徴

最新のコネクタ・タイプである USB Type-C（USB-C）は、薄い楕円形の形状をしています。

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.

性能

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.

外観の特徴

The newest connection type, Thunderbolt 3 and 4 share the same thin oval-shaped port.

This one can get tricky. Just looking at the shape of the port might not be enough, as Thunderbolt 3/4 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.

性能

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.

With Thunderbolt 4, you can rest assured that the port suppports two 4K displays by specification. Thunderbolt 4 shares many of the other benefits of Thunderbolt 3.

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.

For monitors with a USB-C input, these still appear as a thin oval-shaped port, just like a USB-C port on a computer.

Depending on the monitor, this connection can support additional features, such as power to the host and data transfer (through a USB hub on the monitor). Certain USB-C monitors may also rely on the USB-C connection to power the monitor itself (bus-powered).

How many external monitors are you looking to connect to your configuration? Choose between 1, 2, 3, or any number of displays.

Are three displays not enough for you? Take a look at our USB graphics adapters, which allow you to drive additional monitors over a USB connection (up to six on Windows, up to four on macOS). For example, we're able to add an extra two displays to one of our dual display USB 3.0 docks—video demo available!

What is the maximum resolution you're looking to drive through your docking station? You'll want to double-check the monitors that you own, to see if they are standard 1920x1080 (1080p) office monitors, or perhaps fancy 3840x2160 (4K) displays.

For any monitor resolution in between, make sure to select the the maximum resolution one step higher than what is listed. For example, a 2560x1080 display is only supported on docks that support 2560x1440 or above.

You'll want to also pay attention to the refresh rate supported. For those with high-refresh rate gaming monitors that supports up to 144Hz, please be aware that our docks only officially support up to 60hz.
