Does DisplayPort support 144Hz?

To experience gaming at 144Hz refresh rate, you need three important hardware. These; To get the most out of the monitor, a good graphics card, a monitor that supports 144Hz and an optimal data transmission cable compatible with bandwidth. So does DisplayPort support 144Hz?

Usually when we buy a new monitor, there is no cable in the box to connect it to the computer, so you need to know which type of cable is compatible with the bandwidth of your monitor. Not all data transfer cables are the same, and it is most convenient to use the cable that allows us to get the most out of our monitor.

If you have a monitor with a 144Hz refresh rate, there are various cable types depending on the resolution and refresh rate you want to achieve. Below we will see all the relevant information that will help you choose the best option for you.

Which types of cables are compatible with 144Hz?

Resolution Refresh rate Cable type
1080p 144Hz DisplayPort, HDMI 1.3 or Dual-Link DVI
1440p 144Hz DisplayPort 1.2 or HDMI 2.0
4K 144Hz DisplayPort 1.4 or HDMI 2.1

It should be noted that a DisplayPort, DVI Dual-Link, or HDMI 1.3 cable is required to transmit content at 1080p @ 144 Hz, but some monitors limit the refresh rate to 60 Hz or 120 Hz with HDMI; therefore you should consult the manufacturer’s manual. It will always be more convenient to choose the DisplayPort cable.

Does DisplayPort support 144Hz?

DisplayPort cables are one of the most popular options in the gaming world for achieving good resolutions and high refresh rates without sacrificing image quality. As you can see in the table above, all versions of DisplayPort support 144Hz.

  • Gaming monitors with a DisplayPort 1.2 port offer native support for 1080p@240Hz, 1440p@165Hz, and 4K@75Hz.
  • With DisplayPort 1.3 and DisplayPort 1.4, you have enough bandwidth to playback at 1440p@240Hz, 4K@120Hz, 5K@60Hz, 8K@30Hz.
  • The main difference between DisplayPort 1.3 and DisplayPort 1.4 is that DisplayPort 1.4 supports DSC, which allows you to achieve 4K@144Hz, 5K@120Hz, 8K@60Hz with compression.
  • As for Mini DisplayPort cables, they can transmit the same amount of bandwidth as the bandwidth they are based on; hence the mini DisplayPort 1.2 cable supports 1080p@240Hz, 1440p@165Hz, 4K@75Hz etc. It can work at resolutions.

It is worth noting that USB Type C has replaced mini DisplayPort in more modern monitors because it can transmit signals for audio and video, as well as simultaneously charge the device and transfer data.
