Does Displayport 1.4 Support 240hz?

DisplayPort 1.4 is the latest display interface standard developed by the Video Electronics Standards Association (VESA). It supports higher video resolutions, refresh rates, and color depths than its predecessors, making it ideal for demanding displays, such as high-end gaming monitors and large-scale digital signage. One of the most frequently asked questions about DisplayPort 1.4 is whether it supports a refresh rate of 240Hz, which is a popular choice among competitive gamers and enthusiasts who want the ultimate gaming experience.

The short answer is yes, DisplayPort 1.4 supports a refresh rate of 240Hz for 1080p and 1440p resolutions, and even up to 120Hz for 4K and 8K resolutions. However, achieving this level of performance requires several factors, such as the graphics card’s processing power, monitor’s capabilities, and cable’s quality and length. This article will explore the nuances of DisplayPort 1.4’s support for 240Hz, including the technical requirements, limitations, and benefits of using this high-performance display interface.

Does DisplayPort 1.4 Support 240Hz?

• DisplayPort 1.4 is a technology standard for displaying digital video and audio data between devices.

• It supports resolutions up to 8K, as well as high dynamic range (HDR) and variable refresh rates (VRR).

• The maximum refresh rate supported by DisplayPort 1.4 is 240Hz at 1080p resolution.

• However, the actual refresh rate supported by a specific device may depend on various factors such as hardware limitations, cable quality, and software settings.

• To achieve 240Hz refresh rate, both the graphics card and the monitor must support DisplayPort 1.4.

• It is also important to note that achieving a high refresh rate may affect the color accuracy and image quality of the display, particularly with certain technologies such as frame interpolation and motion blur reduction.

• In summary, DisplayPort 1.4 does support 240Hz refresh rate, but the actual performance may vary depending on the device and other factors.


1. Does DisplayPort 1.4 support 240Hz?
Yes, DisplayPort 1.4 supports up to 240Hz refresh rate at 1080p resolution and 144Hz at 1440p resolution.

2. What is the maximum resolution supported by DisplayPort 1.4?
DisplayPort 1.4 supports a maximum resolution of 7680×4320 (8K) at 60Hz and 3840×2160 (4K) at 120Hz.

3. Can I use a DisplayPort 1.4 cable with a DisplayPort 1.2 monitor?
Yes, you can use a DisplayPort 1.4 cable with a DisplayPort 1.2 monitor, but you will be limited to the maximum resolution and refresh rate supported by the monitor.

4. Does DisplayPort 1.4 support HDR (High Dynamic Range)?
Yes, DisplayPort 1.4 supports HDR with a range of 10-bit and 12-bit color depth, providing a wider range of colors and brighter highlights.

5. What is the difference between DisplayPort 1.4 and HDMI 2.0?
DisplayPort 1.4 supports higher resolutions and refresh rates, while HDMI 2.0 supports features such as 3D video and audio return channel (ARC). DisplayPort also supports adaptive sync technology, which matches the monitor’s refresh rate with the graphics card’s output for smoother gameplay.


To sum up, it is good news that DisplayPort 1.4 supports 240Hz, especially for those who need fast and responsive displays for gaming or professional work. With the increased bandwidth and data transfer rates, DisplayPort 1.4 can deliver smoother and more immersive visuals without sacrificing quality. However, it is essential to ensure that your graphics card and monitor are compatible with DisplayPort 1.4 to fully enjoy its benefits. By choosing the right setup, you can get the most out of your high-performance display and enjoy a more seamless and fluid experience.
