Key Differences You Should Know

Now let us look at the specific areas where DisplayPort 1.2 and HDMI differ. These differences can have a big impact on your daily use.

Bandwidth and Speed

DisplayPort 1.2 offers 17.28 Gbps of bandwidth, while HDMI 1.4 maxes out at 10.2 Gbps. This is a huge gap. Higher bandwidth means more data can flow through the cable every second, which directly affects the resolutions and refresh rates you can achieve.

If you want to game at 1440p with a 144Hz refresh rate, DisplayPort 1.2 handles this effortlessly. HDMI 1.4 would struggle, and you might need to drop to 30Hz or lower the resolution. HDMI 2.0 closes this gap, but many older devices still use HDMI 1.4.

Resolution and Refresh Rate Support

Resolution and refresh rate go hand in hand when it comes to display quality. DisplayPort 1.2 can push 4K at 60Hz, which is smooth and detailed for both work and play. It can even handle 5K at 30Hz, though that is less common.

HDMI 1.4, on the other hand, can technically output 4K, but only at 30Hz. That is not smooth enough for gaming or video editing. HDMI 2.0 brings 4K at 60Hz, making it more competitive with DisplayPort 1.2 in this area.

For users who connect their setup to a 2-in-1 laptop with 16GB RAM for creative work, the choice of cable can affect how smoothly your external display performs. You can learn more about pairing your laptop with the right display in our 2-in-1 laptop with 16GB RAM guide.

Audio Capabilities

Both DisplayPort 1.2 and HDMI support multi-channel audio. They can both carry up to 8 channels of uncompressed audio. However, there is one key difference: HDMI supports ARC (Audio Return Channel) and eARC (Enhanced Audio Return Channel).

ARC lets your TV send audio back to your soundbar or receiver through the same HDMI cable. This is incredibly useful for home theater setups. DisplayPort 1.2 does not support ARC, so if you are building a home entertainment system, HDMI is the better choice.

Connector Design

The physical connectors for DisplayPort 1.2 and HDMI are different. DisplayPort has a rectangular connector with a small latch on one side. HDMI has a smaller, trapezoidal connector that also locks in place.

One thing to note is that DisplayPort 1.2 comes in two sizes: full-size and mini DisplayPort. Apple popularized the mini DisplayPort, and you can still find it on some older devices. HDMI also comes in smaller variants, including the Type C (mini HDMI) and Type D (micro HDMI), but Type A (full-size) is by far the most common.

If you are using a laptop and need to connect to an external monitor, make sure you know which port your device has. Many modern laptops use HDMI or USB-C with DisplayPort Alt Mode, so check your device specifications before buying a cable.

Adaptive Sync and Gaming Features

This is where DisplayPort 1.2 really shines. It natively supports adaptive sync technologies like AMD FreeSync and NVIDIA G-Sync. These technologies reduce screen tearing and stuttering during fast-paced games, giving you a smoother gaming experience.

HDMI did not support adaptive sync until HDMI 2.1, and even then, the feature is not as widely adopted in the PC monitor space. If you are a gamer with a DisplayPort 1.2 monitor, you can take full advantage of these features right out of the box.
