DisplayPort 2.1
Direct Answer
DisplayPort 2.1 is a certification-level refinement of the DisplayPort 2.0 specification VESA released in October 2022. Its fastest UHBR20 mode delivers 80 Gbps raw bandwidth -- enough for a single 10K display at 60Hz uncompressed, or multiple high-refresh 4K/8K displays daisy-chained with compression.

A New Encoding Scheme for a Much Bigger Pipe
VESA released the underlying DisplayPort 2.0 specification in October 2022; DisplayPort 2.1 is a certification-level refinement of that same spec rather than a new bandwidth tier. Its fastest mode, UHBR20, uses 128b/132b encoding -- far more efficient than the 8b/10b encoding of earlier DisplayPort versions -- to push raw bandwidth to 80 Gbps, more than double DisplayPort 1.4's ceiling.
That bandwidth is enough for a single 10K (10240x4320) display at 60Hz uncompressed, or -- using Display Stream Compression -- multiple high-refresh 4K or 8K displays daisy-chained via Multi-Stream Transport from one source port, addressing use cases from professional multi-monitor workstations to next-generation home theater and VR displays.
