Computer Ports Explained: HDMI, DisplayPort, USB-C

Tap a port to see its characteristics.

HDMI

The most common port for transmitting both video and audio together, widely used for connecting monitors, TVs, and game consoles.

DisplayPort

Similar to HDMI but supports higher resolutions and refresh rates, commonly used with high-performance gaming monitors.

Ethernet (LAN) Port

A port for a wired internet connection, offering more stable and often faster speeds than Wi-Fi.

USB-C Port

A versatile port that can handle data transfer, charging, and video output all through one connector, now widely adopted on newer laptops and smartphones.

3.5mm Audio Jack

The traditional round connector for wired earphones or headsets.

VGA

An older port that transmits video via an analog rather than digital signal, increasingly rare on newer devices.

SD Card Slot

A slot that lets you insert a camera's or other device's memory card directly into a computer to transfer data.

No More Guessing at the Ports on Your Laptop

Most people have had the experience of not knowing which port to use when connecting a monitor or plugging in an ethernet cable. Knowing each port's shape and purpose in advance makes it much easier to check compatibility when buying a new monitor or peripheral.

Why Older Ports Are Disappearing

As device designs get thinner, ports with bulky connectors or limited capability β€” like VGA β€” are increasingly being phased out in favor of compact, multi-purpose options like USB-C and HDMI.

Frequently Asked Questions

Should I use HDMI or DisplayPort?

Either is fine for typical use, but if you want to get the most out of a high-refresh-rate gaming monitor, DisplayPort is often the better choice.

Why don't newer laptops have a VGA port anymore?

VGA is analog, which limits image quality, and its bulky connector doesn't fit well with thin laptop designs β€” most newer laptops have replaced it with HDMI or USB-C.
