How does DisplayPort 2 stand out?

DisplayPort is a video signal delivery standard that most of us overlook. Basically, it is almost identical to the HDMI interface. The current DisplayPort standard can transmit video and audio signals at 8K 60Hz to TVs and external monitors, while HDMI 2.1 now supports output of videos with a maximum resolution of up to 10K. Of course, DisplayPort still has two sizes: standard (large) and small (similar to Mini HDMI). Just like HDMI cables, DisplayPort cables are quite cheap.

But why do people still prefer to use DisplayPort instead of HDMI? The first reason is that it is suitable for projection settings (output) to multiple screens. Unlike HDMI, DisplayPort has a 'daisy chain' feature that can output to 4 monitors with just one cable. It's neat, easy to use, and this makes computer experts or gamers prefer DisplayPort.

But unless you own a high-end monitor or computer, you'll have little chance of using the DisplayPort interface. Because professionals and gamers often use this interface, manufacturers do not integrate DisplayPort ports into cheap computers, monitors or TVs. So do you need to care about DisplayPort 2 or not? Or is it anything new compared to the old standard?

Here is some information about this new communication standard through VESA's sharing and Howtogeek's website :

Basically, DisplayPort 2 is an upgrade to the specifications compared to the current DisplayPort standard in a more powerful and practical way. Specifically, DisplayPort 2 supports 8K, 10K and 16K video resolutions with a 60 Hz refresh rate (twice the resolution and refresh rate of the old standard). In addition, it has a data transfer rate of up to 77.37 Gbps and supports HDR10. Besides, all DisplayPort 2 integrated devices must support DSC, which is the 'lossless' image compression standard (as little data loss as possible) that some previous manufacturers often overlooked.

It may seem impressive through the above statistics, but it will be even more impressive when you put it into the environment of augmented reality (VR) games. With a transfer rate of up to 77.37 Gbps, DisplayPort 2 is not only ideal for VR gaming, but VESA also claims this upgraded video transmission standard can also play 4K 60 Hz videos through up to 2 devices. wear VR at the same time (via daisy chain protocol).

What's more interesting, DisplayPort 2 is backward compatible with the old DisplayPort hardware (the cable connector doesn't change). Obviously, this new standard has no problem supporting mobile devices like laptops or smartphones, not to mention DisplayPort 2 is also fully compatible with USB Type-C.

So, with 16K video output and VR-friendly data transfer speeds, DisplayPort 2 is probably a futuristic technology and we probably won't have any more upgrades in a decade. next.

If you have never purchased a DisplayPort cable, you may never need to buy a DisplayPort 2 cable again. This is not a format push, but rather a sign that VESA knows how to ensure the existence and universality of the new DisplayPort standard. While the old DisplayPort standard required a dedicated DisplayPort connector, DisplayPort 2 could work over USB-C.

USB-C is set to replace DisplayPort and HDMI ports on most consumer electronics devices (previously it was the standard on newer Macbook models). This is because the USB-C cable also supports the second mode, in other words each USB-C cable contains four data transmission lanes and each lane has a bandwidth of 20 Gbps. In the alternate mode, it is possible to change the direction of these lanes and therefore a computer that can send data with a maximum speed of up to 80 Gbps when output via another monitor is a typical example of the application. use this.

DisplayPort 2's maximum data transfer rate of 77.37 Gbps can be almost 'fit' comfortably through the second mode of the USB-C cable. This does not mean that you will need an adapter to connect the USB-C cable to the TV or monitor. On the contrary, this means that TVs or monitors that are compatible with your future DisplayPort 2 standard will have built-in USB-C and you will be able to transfer videos from any phone or computer to the monitor. Image that is via a USB-C cable with DisplayPort 2 interface.

VESA plans to support the integration of DisplayPort 2 into terminals that will be released by the end of 2020. But really, the transition is entirely up to manufacturers of computers, phones, TVs and monitors. Figure. If a device is not built to support DisplayPort 2, it is at the manufacturer's discretion. A USB-C port will not be enough, but inside the device must be upgraded to the latest DisplayPort standard.

This means that DisplayPort 2 will most likely appear on high-end devices and displays before it can reach lower-cost laptops and TVs. Currently, HDMI 2.1 is capable of 10K video output, so there is not much motivation for manufacturers to rush to give up this technology in low-cost products.
