HDMI 2.0 vs DisplayPort 1.4
HDMI 2.0 carries 14.40 Gbps of video and DisplayPort 1.4 carries 25.92 Gbps, so DisplayPort 1.4 has 1.80 times the room. Of the 13 modes below, HDMI 2.0 carries 0 uncompressed at 10-bit and DisplayPort 1.4 carries 3.
Only DisplayPort 1.4 carries DSC; the other has no fallback when a mode is over its payload.

| 8K 120Hz | Fail, 102.20 Gbps | Fail, 127.75 Gbps | Fail, even with DSC (needs about 4.1:1) | Fail, even with DSC (needs about 5.1:1) |
Results use PC monitor timings (VESA CVT reduced blanking v2 as the headline), not the TV and console timings in CTA-861, so a TV or console may need more bandwidth than shown. RGB/4:4:4 color. DSC verdicts are at maximum compression (8 bpp), the lowest rate VESA's DSC standard allows for 4:4:4, and show the compression each mode needs.
