It's been almost two years since the official announcement of the DisplayPort 2.0 interface protocol (collectively referred to as the DP2.0-equipped protocol below), but there was no information on the launch of related products until recently.
According to the Video Electronics Standards Association (VESA), displays equipped with DP2.0 interfaces are being developed, while new products will use new system chips and are expected to debut in the second half of 2021.
How powerful is the DP2.0 protocol?
According to the design scheme when DP2.0 protocol was released in 19, it has a maximum transmission bandwidth of 80Gbps and a new 128/132b encoding mechanism.
Compared to the previous generation DP1.4 protocol, DP2.0 protocol has 3 times higher data bandwidth performance and up to 97% improvement in efficiency.
In addition compared to the latest HDMI 2.1 protocol, DP2.0 protocol is also 1.6 times higher transmission bandwidth performance.
In addition DP2.0 protocol allows the signal to be carried on the USB4/Thunderbolt 4 interface, although it will be limited by the protocol performance of USB4/Thunderbolt 4, limited to a maximum transmission bandwidth of 40Gbps.
The role of DP2.0 protocol
With such excellent transmission performance, DP2.0 protocol can output 16K@60Hz (DSC), 10K@60Hz lossless, 4K@240Hz, and dual-screen 8K@120Hz video output on a single screen, while also supporting HDR-10 video features. Of course, game enthusiasts like the dual-screen 4K@144Hz lossless is also not in the picture.
In short, the DP2.0 protocol allows for higher display resolutions, faster refresh rates, and support for dynamic HDR functionality, allowing for a wider variety of scenarios.
When will the DP2.0 protocol land?
DP2.0 protocol is so good, so when can we use it?
Unfortunately, DP2.0 protocol-related products will only be unveiled at the end of 2021, and I'm afraid it will take a long time to become popular.
Just as the HDMI 2.1 protocol announced in 2017, only in 2020 into the vision of ordinary consumers.
This is largely because the supporting products have not yet become mainstream, the current market more than 8K @ 60Hz, 4K @ 120Hz display devices on the low side
And the mainstream or a little higher than the mainstream display devices, or 4K@60Hz, 4K@120Hz, 2K@240Hz, not to mention that not everyone is using these types of display devices.
DP2.0 use prospects
So on the current state of the market and user demand, DP2.0 protocol is difficult to be used by ordinary consumers in a short period of time, and at the moment will continue to DP1.4 protocol and HDMII 2.1 protocol.
After all, whether the highest 48Gbps bandwidth HDMI 2.1 protocol, or up to 32Gbps bandwidth DP1.4 protocol, can meet the needs of everyday use.
In addition, even for display devices positioned at the high-end or professional, the use of HDMI 2.1 protocol or DP1.4 protocol can meet a variety of application scenarios.
Broken down into their respective application areas, multimedia terminals such as TVs and game consoles basically use the HDMI protocol, while the DP protocol is mostly found in monitors, graphics cards and other terminals.
