DisplayPort Cable for 240hz – 2023 Buyer’s Guide

DisplayPort cable allows you to use a single cable to send both audio and video signals from a source device like a PC or laptop to a display or monitor. They’re comparable to HDMI cables. However, they currently only work between computers and monitors, so you can’t use them with gaming systems. 

The best DisplayPort cables for 240 Hz refresh rates in 2023 are all DisplayPort 1.4 cables. They work well for professionals, individuals, and gamers who need to transfer visual and audio data from their computer to a single or multiple monitors.  

Best DisplayPort Cable for Gaming

While DisplayPort 2.0 cables have been out since 2019, they’re still not as easy to find in 2002. Thus, DisplayPort 1.4 remains the most popular version and maintains the highest ratings in the market. 

Plus, many computer display devices haven’t yet caught up to the technology of DisplayPort 2.0. Thus, the best DisplayPort cables for 240 Hz for 2022 are all DisplayPort 1.4 cables.

DisplayPort Types

There are two main types of DisplayPort cables: 

  • Standard DisplayPort cable: Most common
  • Mini DisplayPort cable: Smaller cables, ideal for smaller devices, compatible with Apple devices, widely used with Thunderbolt technology

However, DisplayPort has released seven different versions of DisplayPort cables:

  • DisplayPort 1.0 (2006): typical resolution of 1440p @ 60 Hz
  • DisplayPort 2.0 (2007): typical resolution of 1440p @ 60 Hz
  • DisplayPort 1.2 (2009): typical resolution of 4k @ 60 Hz
  • DisplayPort 1.3 (2014): typical resolution of 4K @ 120 Hz, 8K @ 60 Hz (with DSC)
  • DisplayPort 1.4 (2016): typical resolution of 4K @ 120 Hz, 8K @ 60 Hz (with DSC)
  • DisplayPort 1.4a (2018): typical resolution of 4K @ 120 Hz, 8K @ 60 Hz (with DSC)
  • DisplayPort 2.0 (2019): typical resolution of 8K @ 60 Hz

Lowest and Highest Specifications the DisplayPort Cable Supports

DisplayPort cables handle a wide range of resolution and refresh rates:

  • Resolution: 2K (25060 x 1440) to 16K (15360 x 8640)
  • Refresh rate: 60 Hz to 240 Hz

However, accomplishing a 240 Hz refresh rate requires a smaller, 4K resolution. Meanwhile, having the largest 16K resolution leaves you at a 60 Hz refresh rate.

Uses of DisplayPort Cable

Common uses for DisplayPort cables include: 

  • Professional business displays: DisplayPort cables originally were most popular for business-related, professional-grade laptops and desktops. 
  • High-end graphics cards and high-resolution monitors: DisplayPort cables are common on high-quality devices with high-end graphics cards or high-resolution monitors. They support high resolutions and high refresh rates. 
  • Multiple monitors: One common use of DisplayPort cables is for multiple desktop monitors. Having multiple monitors can increase productivity, while having a single cable to transfer both video and audio to each monitor is more convenient.
  • PC gaming: Another common use of DisplayPort cables is for PC gaming because higher refresh rates provide a better and faster graphics experience. 
  • Freeing up HDMI ports: Additionally, using a DisplayPort cable can free up your HDMI ports if you want to connect a game console or other device.

How 240 Hz Helps With Gaming

A DisplayPort cable allows gamers to experience the full capabilities of advanced graphics. While it’s possible to use an HDMI connection, DisplayPort cables tend to be a better option because they support a wider range of resolutions and refresh rates. 

For the purpose of gaming, monitors with 240hz refresh rates give you 

  • Smoother, less choppy animations
  • Easier target tracking
  • Reduced ghosting
  • Reduced tearing
  • Minimized distracting effects
  • Less lag time


Here are common questions that people ask about DisplayPort cables. 

What’s max distance a DisplayPort cable can handle?

The maximum length of a DisplayPort cable is 49 feet. However, most come in sizes up to 15 feet. DisplayPort extension cables beyond 30 feet can cause a decrease in signal quality for some resolutions.  

Is DisplayPort better than HDMI?

Whether a DisplayPort cable is better than HDMI depends on your needs. DisplayPort cables can support a higher bandwidth than HDMI cables. Meanwhile, HDMI 2.1 can support a wider range of resolutions and is compatible with more devices beyond monitors and computers.  

What’s the speed of transfer on a DisplayPort cable?

DisplayPort 2.0 has the highest transfer speed of 77.36 Gbps. However, the data transfer speed for DisplayPort depends on the version of the cable that you have, with: 

  • DisplayPort 1.0: 5.18/8.65 Gbps
  • DisplayPort 1.1: 8.64 Gbps
  • DisplayPort 1.2: 17.28 Gbps
  • DisplayPort 13: 25.92 Gbps
  • DisplayPort 1.4: 25.92 Gbps
  • DisplayPort 14.a: 25.92 Gbps
  • DisplayPort 2.0: 80 Gbps

What is the highest resolution for DisplayPort?

DisplayPort 2.0 produces the highest resolution: 16K at 60 Hz with DSC (15360 x 8640 pixels).

What is the max refresh rate for DisplayPort?

The highest refresh rate for most DisplayPort cables is 240Hz. However, the infinnit DisplayPort cable has maximum refresh rates up to 390Hz.

Do all DisplayPort cables support 240Hz?

All DisplayPort cables are capable of supporting 240Hz. 

What cable supports 1440p 240Hz?

DisplayPort 1.2, DisplayPort 1.3, DisplayPort 1.4, DisplayPort 1.4a, and DisplayPort 2.0 cables all support 1440p at 240Hz.

Final Thoughts on DisplayPort Cables for 240hz

DisplayPort cables tend to provide a better, clearer, more dependable image experience than some of the cables that come with some monitors. So, they can solve many glitching, ghosting, and syncing issues. 

All DisplayPort cables can support 240Hz refresh rates (and some support even higher refresh rates). However, keep in mind that a higher refresh rate comes with a decreased resolution between 1080P and 4K.  

In 2023, the best DisplayPort cables are still the 1.4 versions, but 2.0s are right around the corner as the technology becomes more readily available.
