Port 1.4 vs. 1.2: What is the Difference?

While there are various types of high-end cables, very few can match the performance of DisplayPort cables. These cables deliver a wide-ranging bandwidth transmission. DisplayPort 1.2 was the first version and DisplayPort 1.4 version followed soon after. One notable feature about the DisplayPort versions is that the newer version improved the features that came with its predecessor. While this is the case, DisplayPort 1.2 is still remarkable when it comes to performance.


The performance

DisplayPort 1.2 delivers an impressive bandwidth of about 21.6 Gigabytes per second over four lanes. It also has a maximum data transfer rate of about 17.28 gigabytes per second. When it comes to the DisplayPort 1.4, it features a 4-lane construction but offers advanced performance. This model has an impressive bandwidth of up to 32.40 gigabytes per second and a 25.92 Gbps maximum data rate.

The performance rate for DisplayPort 1.3 and DisplayPort 1.4 is similar, except for one updated feature on the latter. Unlike the predecessor, DisplayPort 1.4 includes a Display Stream Compression (DSC). This compression format offers a broader resolution range and higher refresh rates in comparison those allowed by its bandwidth. So what is the main difference between DisplayPort 1.2 and DisplayPort 1.4?

Which DisplayPort is right for you?

When comparing the two DisplayPort, one thing is clear, DisplayPort 1.4 has improved specifications than the DisplayPort 1.2. Nevertheless, what do these numbers mean? After releasing the DisplayPort 1.2 in 2010, the model brought about a revolution in the data transmission field. DisplayPort 1.2 was the first model to bring exclusive features such as self-panel refresh and adaptive synchronization. The version also improved on the resolution allowing it to reach a resolution of 1080P at up to 240Hz, 4K at 75Hz, and opening an option of 5K resolution at 30Hz.

As mentioned earlier, DisplayPort 1.4 improves performance. In terms of resolution and refresh rate, the model supports 1440p at refresh rates of up to 240Hz. It also supports 4K at refresh rates of up to 120Hz, 5K at 60HZ refresh rate, and an impressive 8K resolution at 30Hz.

DisplayPort 1.4 also integrates the DSC 1.2 to handle a more comprehensive resolution range and higher refresh rates in comparison those allowed by its bandwidth. Specifically, when the DSC is enabled, this version can handle 4K at a refresh rate of 60Hz with HDR. Even better, it can also achieve an 8K resolution at a refresh rate of up to 60Hz. It is also important to note that the DisplayPort 1.4 works with previous version DisplayPort devices that use a standard size or the mini DisplayPort commotion.

DisplayPort 1.4 vs. 1.2 cables – Our verdict

Thanks to the advanced features that come with the DisplayPort 1.4, this model is the absolute winner. It is important to note that even if your device comes with a DisplayPort1.2 using a DisplayPort 1.4 cable is wise. As stated, the cables are backward compatible. This means you can still use the cable when you upgrade the hardware. Of course, this will save you the costs of replacing the cables.
