DisplayPort 2: What's different and why is it important?

The Video Electronics Standards Association (VESA) has just announced the latest iteration of DisplayPort technology: DisplayPort 2. This new standard supports resolutions up to 16K and uses either traditional DisplayPort connectors or USB C. They will probably get their hands on it by the end of 2020.

What is DisplayPort?

DisplayPort is the video broadcasting standard that most people have never heard of. Basically it is almost identical to HDMI. The current iteration of DisplayPort can transmit 8K video and audio at 60 Hz to TVs and monitors (HDMI 2.1

supports 10K). It comes in a big and small form factor (like mini HDMI). And like HDMI cables, DisplayPort cables are really cheap.

Why is DisplayPort used at all? First, it is useful for multiple monitor setups. Unlike HDMI, DisplayPort has a fancy "daisy chain" feature. You can connect a monitor to your computer through DisplayPort, and then move DisplayPort cable from this first monitor to the other screens in your setup. It's clean, intuitive and loved by computer professionals and PC gamers.

However, if you do not have a high-end monitor or computer, chances are you will not be able to use DisplayPort at all. Because it's commonly used by professionals and gamers, manufacturers do not have to install DisplayPorts in cheap computers, monitors, or televisions. So you should be interested in DisplayPort 2? Is it groundbreaking in any way?

DisplayPort 2 is Future-Ready and Ready for VR

The latest version of DisplayPort is essentially an upgrade to DisplayPort's current specifications. It is nice cut and dry. DisplayPort 2 supports video resolutions of 8K, 10K, and 16K with a refresh rate of 60Hz (twice the resolution and bandwidth of current DisplayPort standards). It transmits data at a speed of 77.37 Gbps and will support HDR10. In addition, all DisplayPort 2 devices require DSC support. This is a standard for lossless image compression that some manufacturers ignore.

These specifications are impressive alone. However, they are more impressive when you consider how they can affect virtual reality gaming. DisplayPort 2's 77.37 Gbps payload transfer is more than ideal for VR games, and VESA claims that the updated video standard can simultaneously send 4K-60Hz video to up to two VR headsets ( via the daisy-chain feature, which is of course part of) from DisplayPort 2).

And fortunately, DisplayPort 2 is compatible with older DisplayPort hardware (the cable shape has not changed). This should not be a problem for small devices like phones and laptops – USB-C is also fully compatible with DisplayPort 2 (more in seconds).

With 16K video and VR-friendly data transfer speeds, DisplayPort 2 looks forward-looking. It's possible we will not see a video standard update for another decade.
