Are you looking for how to connect Displayport 1.2 Monitor To 1.4 GPU? A helpful video connector, DisplayPort, is found in many PCs and displays. To compete with other video connections, DisplayPort releases updated versions of its video ports and video cables on a regular basis.

Depending on when you purchased your devices and cables, you most likely have several DisplayPort versions on them. However, what should you do to connect two DisplayPort components of different versions?

Can I use Displayport 1.2 Monitor To 1.4 GPU:  Due to DisplayPort’s complete backward compatibility, we have discovered that using DisplayPort 1.4 on 1.2 is OK. This implies that any version can be used with any other version, regardless of whether the parts are cables or video ports. We recommend choosing 1.4 for the cable to get the best video quality.

Displayport 1.2 Monitor To 1.4 GPU

Club3D VESA  Licensed CAC-2068 1.2 devices can use 1.4 wires without any issues. Will a 1.4 GPU operate with a display port 1.2 connection and monitor? Yes, if it is certified as HDMI 1.2, it will function at least up to 1080p 60Hz; however, this is not assured. It may also function higher to give 1440p and 4K output.

How To Use Displayport 1.2 Monitor To 1.4 GPU

Any HDMI-spec device will function with any HDMI cable. However, the signal speeds it can pass may be constrained. It will still negotiate down. If you’re concerned, spend $10 on an HDMI 2.1 cable and start using it; that way, the cable will be as “future-proof” as possible while you gradually upgrade your equipment.

What Is DisplayPort 1.2?

DisplayPort 1.2 includes four data lanes, a refresh rate of 60 Hz, and a maximum adequate bandwidth of 17.28 Gbps. It also supports 4K monitor resolutions. HBR2’s second iteration was released with DP 1.2, featuring the Multi-Stream Transport System ( More on MST Here).

What Is DisplayPort 1.2

DisplayPort is also compatible with Thunderbolt, Mini DisplayPort, and USB-C connectors. Both adaptive and passive adapters are DP 1.2 compliant and exhibit noticeable audio and video synchronization improvements.

What Is DisplayPort 2.0?

In 2019, DisplayPort 2.0 was introduced. This new standard now includes several capabilities thanks to DP 2.0. Monitor resolutions up to 8K @ 60 Hz are supported via DisplayPort 2.0. For true cutting-edge enthusiasts, 10K @ 60Hz & 16K @ 60 Hz monitor resolutions are also supported.

What Is DisplayPort 2.0

The adequate bandwidth now has the most recent Ultra High Bit Rate and was increased to 77.4 Gbps (UHBR). DisplayPort 2.0 additionally has an optional feature called adaptive sync.

The DP 2.0 standard data lanes would be incorporated into the USB-C connector using DisplayPort Alt-Mode. Three 4K monitors at 144 Hz could be supported using USB-C DP Alt-Mode by employing DSC. Future products will use the DP Alt-Mode more frequently as the size and compatibility of devices migrate to USB-C.

What Is DisplayPort 1.4?

In 2016, DisplayPort 1.4, which followed the unimpressive DP 1.3 release, brought about several significant advancements. Depending on the resolution selected, DisplayPort 1.4 enables refresh rates up to 120 Hz and 60 Hz for both 4K and 8K monitor resolutions.

What Is DisplayPort 1.4

Four data lanes were added, increasing the bandwidth to 25.92 Gbps. With DP 1.4, HBR3 (Bit Rate Class 3) was added. Display Stream Compression (DSC), a feature of Display Port 1.4, enables the presentation of 4K content at 240 Hz.

DisplayPort Pros

  • Royalty-Free – Lowers costs for OEM, ODM, and end users.
  • MST Support – Multi-Stream Support simplifies expanding your desktop. SST needs to be clarified and constrained.
  • 8K Resolution – 8K is the new 4K, so bring in the high resolutions. The resolutions are growing better and more seamless each time.
  • DP Adapters – It’s a big thing for a widely used standard like DisplayPort to function with other standards like HDMI.
  • Type-C Alt Mode Connection: USB-C is the future! Simply put, Displayport increased its power. Compared to Thunderbolt 3 or 4 solutions, USB-C DP Alt-Mode is far cheaper, and depending on what you need it for, it can be mighty.

How Do You Use DisplayPort 1.4 On 1.2?

Here’s how to use DisplayPort 1.4 on 1.2:

  • Use the most recent version of the DisplayPort video cable.
  • Connect one end to your computer’s video port.
  • Connect the other end to your display’s video port.
  • Please turn on your display by connecting it to a power source.
  • Start your computer. Its video ought to now be visible on your screen.

What Happens If I Use HDMI 1.4 For A 144Hz Monitor On A 1440p Resolution?

Nothing unique! Your only restriction will be a 75Hz refresh rate. It is the HDMI 1.4 bandwidth’s maximum power. It is also capable of 4K. But only at a maximum of 30Hz. The optimal overall minimum for 1440p at 144Hz is display port 1.2.

Much better is 1.4. Regarding HDMI, the 2.0 version supports 1920×1080 at 240 Hz, 1440p at 144 Hz, and 4k at 60 Hz. That is also a wise choice for you. And lastly, 4K at 120Hz is supported by HDMi 2.1. I have not heard of anything newer than HDMI 2.1 or Display Port 1.4.

Yet, considering that Display Port 1.4 is much more recent than HDMI 2.1, Display Port is probably due for an update. What will the version be called, though? 1.5? 1.6? Or 2.0? Nobody is yet aware!

Which DisplayPort Cables To Buy?

Given all of the upgrades in DisplayPort 1.4, it easily wins. Get a high-quality DisplayPort 1.4 cable from a firm like Cable Matters if you’re looking for a DisplayPort cable. A high-quality DisplayPort 1.4 cable is still a fantastic option, even if your current hardware only supports DisplayPort 1.2. When you decide to upgrade your gear, you can avoid new cables since they are backward compatible with your current setup.

What’s Next?

For many years, DisplayPort 1.4 has been the best high-end cable, especially if you purchased it from Cable Matters, where we can ensure that the connectors have high-quality anti-noise shielding and anti-corrosion protection. However, DisplayPort and its rivals’ standards are constantly changing.

The last few years have seen the adoption of HDMI 2.1 as the new standard for A/V and gaming connectivity because it is a more capable cable, and more devices are supporting it, especially in light of the introduction of new gaming consoles from Sony and Microsoft.

However, with the recent ratification of DisplayPort 2.0 as a standard, high-performance connectors and cabling will retake the lead. The debate between DisplayPort 1.4 and 1.2 is crucial, but shortly, it will be between DisplayPort 2.0 and HDMI 2.1.


Because DisplayPort is backward compatible, you can use any version on any other version, so you can use DisplayPort 1.4 on 1.2. The video broadcast, however, might have a reduced quality if you utilize a DisplayPort video connection that is an older version than your video ports.

The fundamental changes between DisplayPort 1.4 and 1.2 are as follows: DisplayPort 1.4 offers Display Stream Connection with a greater maximum total bandwidth, data rate, resolution, and FPS. There is no doubt that DisplayPort 1.4 is superior to DisplayPort 1.2 for a high-quality video connection.

If you have an HDMI 2.1 port, DisplayPort 1.4 is inferior to HDMI 2.1 in terms of performance. Use the optic cable with the highest version and connect the ports to use Displayport 1.2 Monitor To 1.4 GPU. We hope you found this helpful post.
