HDMI vs. DisplayPort

Designed for different uses, HDMI and DisplayPort support different technologies. Each with its advantages depending on your use. First of all, TV is equipped with HDMI, with a few infrequent exceptions. While PC monitors have both connectors. The AMD or Nvidia graphics cards have several HDMI and DisplayPort ports.

The most crucial point is simply the supported definitions as well as the refresh rate. More precisely, it is the connection of the HDMI or DisplayPort. Concretely, the higher the definition and the higher the refresh rate, the more the quantity of data that passes is essential.

The connection. Depending on the version, this connection increases with the upcoming HDMI 2.1 or DisplayPort 2.0 standards. We discuss this point in more detail in the following article.

Technologies supported by Hdmi DisplayPort Adaptor

Then to differentiate between HDMI and DisplayPort, there are the supported technologies:

  • HDMI: only compatible with FreeSync
  • DisplayPort: FreeSync and G-Sync compatible

Multi-Stream Transport or MST: This is a technology that allows several monitors to be connected in a line. Only present on DisplayPort, from version 1.2, this feature will enable you to run several streams on the same cable.

Note: The bandwidth is shared between the different monitors. It is possible to daisy chain or uses DisplayPort Hubs.

HDMI is not compatible with MST, but it is possible to achieve a similar result using one hdmi displayport adapter. However, for the supported technologies, DisplayPort has the advantage.

Hdmi Displayport Comparison

As we have seen, the main difference is the supported resolution as well as the refresh rate. It will usually guide your decision towards one or the other. To get an idea, here is a table below:

HDMI or DisplayPort? Which one is best to connect PC or TV 1

However, this table does not take DSC (Display Stream Compression) technology. The latter makes it possible to compress the video signal to increase the bandwidth, allowing DisplayPort 1.4 to manage 4K at 144 Hz. For DSC to work, all devices in the chain must be compatible. Note, HDR signals consume more bandwidth.

The standards on the market are DisplayPort 1.2 or 1.4 and HDMI 1.4 or 2.0. The HDMI 2.1 standard significantly increases the bandwidth, but it also adds VRR management for TV and an ALLM mode for low latency.

This is why if you buy a TV soon, choose a Gaming TV with HDMI 2.1. PS5 and Xbox Serie X consoles should benefit from this.

Note: Some HDMI 2.0 TV are ALLM compatible.

While waiting for the market to change, on a PC Monitor, favor DisplayPort.

HDMI or DisplayPort for 144 Hz?

The hdmi or displayport for gaming and especially for high refresh rates, Select a DisplayPort cable on a PC monitor. For buying, make sure you have at latest version 1.4. Even if your monitor only has a DisplayPort 1.2, prefer a 1.4 cable for the future.

The other argument in favor of DisplayPort is that it supports both VRR technologies, FreeSync and G-Sync.

Which DisplayPort to choose?

Make sure to take a version 1.4 at least. Whether for a PC monitor, a graphics card, or an hdmi and displayport cable.

Whether it’s DisplayPort or HDMI, both technologies have limitations on cable length. For DisplayPort, it is recommended not to exceed 3 meters. In usage, it depends on the definition. In the vast majority of cases on a PC, DisplayPort is preferred.

When buying, the 1.4 or 2.0 compatibility is not often highlighted on the product sheets. Most of the time, when not listed, the cable is DisplayPort 1.2 compatible.

Here are some links with hdmi vs displayport quality products and compatibility displayed clearly to avoid any unpleasant surprises to save time.

Which HDMI to choose?

For an HDMI cable, we prefer version 2.0 or, if possible, 2.1. To take advantage of the capabilities of version 2.1, you will need to have compatible devices, but it is also an anticipation of your future devices.

Which HDMI to choose

Regarding the maximum length, the maximum length is more significant with this type of cable: for 1080p maximum 10 meters; for 4K maximum 10 meters. Still, hesitating between HDMI or DisplayPort? If none of the above criteria have guided you, then go for DisplayPort.

While buying, check the HDMI well. If the information is not present, it is often a dated version, I.E., 1.4. Also, there is a significant price difference between a 2.0 and 2.1 cable, so if version 2.0 is enough for you, no need to spend more. To avoid unpleasant surprises when buying, here are some links with 2.0 or 2.1 certified cables:

DisplayPort Alternate over USB-C

To pass the video signal over USB-C with the DisplayPort. Alternate Mode is a feature of the DisplayPort standard since 2014. This Mode allows you to pass USB 3.0 information, USB power, and video signal with the same cable.

You will find this interface on some screens, some graphics cards, but especially on compact devices. Like, for example, laptops, smartphones or tablets, and other multimedia devices.

With the DisplayPort 2.0, it is possible to pass a video signal in 16K and 60 Hz over USB-C (USB 4.0 to come) with Alternate Mode. This means that this Mode can carry a video signal for two 8K monitors at 60 Hz.

It is just a summary of the leading technologies supported by the DisplayPort or HDMI standards. HDMI supports other technologies, such as ARC, eARC, and Ethernet-over-HDMI. But these technologies are primarily designed for TV. Usually, they are not supported on PC monitors.
