With new specs, you might be wondering what DP 2.1 is

Let’s say you’re enjoying 4K or 8K graphics with a fast frame rate. In this case, you need a connection and a port to manage the massive amount of data being delivered from your PC to your monitor. This is where DisplayPort 2.1 comes into play.

It should be noted that DisplayPort 2.0 has been superseded by the newer DisplayPort 2.1 specification. Therefore, all previous DP 2.0 devices are now also DP 2.1 certified. No structural changes have been made to the ports or cables of the new DisplayPort 2.1.

Instead, it focuses on improving USB4 compatibility and DisplayPort over USB Type-C (DisplayPort Alt Mode). USB-C and USB4 are separate standards developed by the USB Implementers Forum and are expected to be implemented by most devices in the coming years.

Therefore, DisplayPort 2.1 is compatible with any device or product that previously supported DisplayPort 2.0. In order to be certified for DisplayPort 2.1, manufacturers must adhere to its specifications, according to VESA’s clarification to Ars Technica.

The display standard is now more effective when used with USB, although these additions don’t increase its maximum resolution or refresh rate.

DisplayPort 2.1 includes mandatory compatibility for VESA’s Display Stream Compression (DSC) and Panel Replay technologies and bandwidth management.

Additionally, to be certified for use with DisplayPort 2.1 devices, DP40 and DP80 cables must operate at maximum capacity at lengths greater than 2 m (6.6 ft) and 1 m (3.3 ft), respectively. It seems only logical that VESA would want to ensure its standards are compatible with this port given its increasing adoption.

While there is no need to think about DP 2.1 just yet, since DP 1.4 with DSC can already deliver extremely high resolutions and refresh rates (4K 240Hz 10bit, 1440p 500Hz+ 10bit, etc.), we have seen customers waiting around their GPUs or Replace monitors until DP 2.1 comes out.

This new specification is the first to come out in the AMD RDNA 3 cards. These are due out in mid-December, but the new compatible monitors are yet to come. With a hint that they will appear in early 2023.
