Can DisplayPort 2.1 support uncompressed 8K 60Hz? Bandwidth analysis
8K at 60 Hz with 10-bit 4:4:4 HDR needs 66.9 Gbps, the same bandwidth as 4K 240 Hz HDR, because total pixel throughput is what determines the signal requirement. DisplayPort 2.1 UHBR 20 handles it natively with roughly 13% headroom to spare.
Interface Bandwidth Analysis
See how much uncompressed and compressed bandwidth this resolution and refresh rate mode demands, compared to the native limits of common video cables.
DSC uses visually lossless 3-to-1 compression, shrinking the required bandwidth so it fits through older cables.

How this is calculated
UHBR 13.5 (52.22 Gbps) and UHBR 10 (38.69 Gbps) can't reach this mode uncompressed. You'd need DSC, 4:2:2 chroma, or an 8-bit SDR fallback to 53.5 Gbps (which UHBR 13.5 just manages). HDMI 2.1 at 40.1 Gbps real throughput requires DSC for 8K 60 in any color mode. UHBR 20 and HDMI 2.2 (85.33 Gbps) are the only interfaces carrying 8K 60 HDR uncompressed today.
Verdict
8K 60 HDR is the second flagship mode UHBR 20 was built for. For creators working at 8K or display installations needing uncompromised signal fidelity, it's the interface tier that matters.
