How many HZ does DisplayPort Support?

Refresh Rate (HZ) & Resolution of DisplayPort [All Version]

Refresh Rate & Resolution is crucial when you play games, stream, video edit, and do other high-end stuff.

When you have a new DisplayPort setup, you must know its refresh rate and resolution capability to fulfill your needs.

So, How Much Refresh Rate (HZ) & Resolution Does DisplayPort Support?

The Refresh Rate & Resolutions of DisplayPort depends on its version, and there are different versions of DisplayPort. The most popular DisplayPort version, 1.2, can support 60 Hz for 4k resolution, whereas the current most sold DisplayPort 1.4 can support 120 Hz for 4k and 60 Hz for 8k. The latest DisplayPort 2.0 can support 144 Hz for 4k, 120 Hz for 8k, and 60 Hz for 16k resolution.

The refresh rate depends on resolution; if the resolution increases, the refresh rate decreases. That’s why it is more important to look at the capabilities before shifting to DisplayPort.

Refresh Rate & Resolution of DisplayPort 1.0

DisplayPort 1.0 is the first version, released in 2007 by VESA. So in terms of specification, you can understand it has pretty outdated features.

The oldest DisplayPort 1.0 is capable of a 144Hz refresh rate at 1080p resolution, which I think was a great starting by VESA. It has a bandwidth of 10.8 Gbit/s.

As mentioned earlier, it does not have some advanced features like backward compatibility and others.

Refresh Rate & Resolution of DisplayPort 1.2

Launched in 2010, DisplayPort 1.2 is the most popular DisplayPort version. Although, people are shifting to the newest versions, according to various data on the web.

So, the DisplayPort 1.2 can support 3840 × 2160 or 4k resolutions at a 60HZ refresh rate or 60 FPS. If you run videos or games at 1080p or 1440p resolutions, you can get up to a 144Hz refresh rate.

Playing games at 4k resolution is fine and has the most advanced features.

Refresh Rate & Resolution of DisplayPort 1.3

DisplayPort 1.3 is not that popular, and people have not brought it much.

DisplayPort 1.3 supports 4k UHD resolutions at a 120 Hz refresh rate. So again, great if you play games at 4k and your FPS requirement is 120HZ.

This version launched only a year after DP 1.2, so people mostly adapted to 1.2, and this version is not that popular.

Refresh Rate & Resolution of DisplayPort 1.4

Now, the most used version at present, DisplayPort 1.4, has some cool features for all of us. It was launched in 2016.

DisplayPort 1.4 supports 8K UHD (7680 × 4320) resolutions at a 60hz refresh rate; if you run 4k resolution, it can have a 120hz refresh rate. It is the first version to support 8k resolution.

This can be great if you play games or do other things at 4k and 8k resolutions.

DisplayPort 1.4a, which VESA launched in 2018, but not many details are available about this version.

Refresh Rate & Resolution of DisplayPort 2.0

Now, let’s dive into the latest and most exciting version of DisplayPort, which is DisplayPort 2.0. It was launched in 2016, but the greater production started after 2021.

This DisplayPort 2.0 can support 16k resolution at a 60Hz refresh rate. So this is the starting, or we can say the first port with 16k resolution capability. As it supports the higher resolution, it is obvious it will be a great option for a multi-monitor setup or daisy chain.

If you run 8k resolution with DisplayPort 2.0, it can handle 120HZ; for 4k resolutions, it is capable of 144HZ; for 2k resolution, 165HZ refresh rate at max.

Let’s take a look at how many resolutions and refresh rates you’ll get with a single and multi-monitor setup;

1) Single display resolution

  • 16K display at 60Hz
  • 10K display at 60Hz

2) Dual Display Resolution

  • Two 8K displays at the rate of 120Hz
  • Two 4K displays at the rate of 144Hz

3) Triple Display Resolution

  • Three 10K displays at the rate of 60Hz
  • Three 4K displays at the rate of 90Hz

Which DisplayPort Versions Should You Have?

The answer depends on you and your daily life requirements. If you play games at 4k resolution and 60 fps, then you can go with 1.2, whereas if you have a requirement of 120hz with 4k resolution, then DisplayPort 1.4 is the perfect suit; and if you’re quite advanced and want to play games at 4k @144hz, then latest 2.0 is best for you.

If you don’t play games at 4k or are a new gamer, then DisplayPort 1.2 is well enough for you. Although, you have to take care of the refresh rate and buy the version according.

For 8k gamers, DisplayPort 1.4 and 2.0 is suitable, whereas for 16k resolution, DisplayPort 2.0 is the only option.

Another important thing is deciding if you want more resolution or refresh rate [FPS] as I told refresh rate decreases if you increase the resolutions.

So the refresh rate will depend on what resolution you play games or stream videos. Thus, you can manually set the resolution to increase the refresh rate.

I hope this post can tell you how many Hz DisplayPort support and what resolution you can get.
