As of writing, though, there's no hardware that supports DisplayPort 2.0, and due to global delays, we likely won't see any until late 2021 at least.

This would theoretically make it possible to achieve resolutions of up to 16k with compression or lower resolutions with much higher refresh rates than is currently possible.

DisplayPort 2.0 has also been announced, and it has an even higher maximum bandwidth than HDMI 2.1 at nearly triple the bandwidth of DisplayPort 1.4. Compared to standard HDMI 2.0, DisplayPort 1.4 is superior. Expect that to change soon, though, as a number of manufacturers announced HDMI 2.1 monitors at CES 2021. HDMI is technically superior thanks to the release of HDMI 2.1, which surpasses the capabilities of DisplayPort 1.4, but monitors that support it are scarce. While the exact specifications vary depending on a few other factors, below is a list of the approximate maximum formats each connector can support.

Most monitors on the market today support either DisplayPort 1.2 or 1.4 and/or HDMI 1.4 or 2.0. The maximum resolution and refresh rate available depends on the specific versions of DisplayPort and HDMI available to you. Each has its own advantages depending on how you plan to use it. HDMI and DisplayPort were designed for different uses, so they support different technologies.
