Capability library / video
Version, cable class, active conversion, direction and the chosen timing all matter.

| Name or mark | Supported reading and conditions | Do not infer | Authority |
|---|---|---|---|
| Ultra High Speed HDMI cable | Up to 48Gbps cable classVerify cable model/length, source, intermediary and display mode. | The cable class does not certify the whole setup. | S516 · HDMI Licensing AdministratorChecked 2026-10-11 |
| Ultra96 HDMI cable | Up to 96Gbps cable classCheck official certification details for the exact cable. | Does not add an unsupported source/display feature. | S516 · HDMI Licensing AdministratorChecked 2026-10-11 |
| Ultra96 on a device | Maximum may be 64, 80 or 96GbpsRead the exact port specification. | The name alone does not establish a 96Gbps port. | S517 · HDMI Licensing AdministratorChecked 2026-10-11 |
| DisplayPort 2.1b device | Version, not a fixed link-rate promiseRead the implemented rate, lanes and required features. | UHBR20 is not implied by the version alone. | S519 · VESAChecked 2026-10-11 |
| DP54 / original DP40 certified cable | DP54 performance class; original DP40 validation acknowledged by VESACheck the exact cable’s certification and both endpoint rates. | Do not apply certification claims to merely advertised DP40 cables. | S520 · VESAChecked 2026-10-11 |
| DP80 cable | Four-lane UHBR20 / 80Gbps classUHBR20-capable source and sink plus the qualified cable. | Not 80Gbps available video payload or a resolution guarantee. | S520 · VESAChecked 2026-10-11 |
| DP80LL active cable | Up to 80Gbps; up to three metersDocumented low-loss active cable and suitable endpoints. | Not a blanket approval of all cables at this length. | S520 · VESAChecked 2026-10-11 |
| USB-C to DisplayPort | Native DP Alt Mode pathHost output, cable and destination input must support the path. | USB data/charging alone does not establish Alt Mode. | S519 · VESAChecked 2026-10-11 |

02 / FOLLOW THE ACTUAL PATH
Supported under stated conditions, excluded within a stated scope, or not established. Only 6 cases belong to this desk; none is a universal compatibility approval.
Not established · not hardware tested
No exact rate follows: the official feature name covers three stated maxima.
Still unknown. The two port implementations and selected timing remain missing.
Next check. Look up the exact rate rather than using the feature name as a number.
Basis: source-scoped interpretation. This classifies only the stated proposition, not an entire equipment pairing.
HDMI LA’s Ultra96 device feature name can indicate a maximum of 64Gbps, 80Gbps or 96Gbps; the feature name alone does not identify which maximum the device implements.
Device feature naming, not the separate Ultra96 HDMI cable certification class.
HDMI LA identifies Ultra96 HDMI cables as supporting up to 96Gbps; verification information identifies the cable brand, model and length.
Exact cable-class and certification scope, separate from device implementation.

Not established · not hardware tested
A certified cable establishes a cable class, not a new endpoint feature.
Still unknown. Resolution, refresh rate, chroma, bit depth and compression are unspecified.
Next check. Check the complete timing at each stage; do not promise a mode from cable branding.
Basis: source-scoped interpretation. This classifies only the stated proposition, not an entire equipment pairing.
HDMI LA identifies Ultra High Speed HDMI cables for system configurations up to 48Gbps and requires cable certification labels.
Cable-class evidence, not proof of a source or display’s selected video timing.
HDMI LA identifies Ultra96 HDMI cables as supporting up to 96Gbps; verification information identifies the cable brand, model and length.
Exact cable-class and certification scope, separate from device implementation.
Not established · not hardware tested
No. VESA allows certification without UHBR under its specified feature conditions.
Still unknown. The endpoints’ rate capabilities have not been supplied.
Next check. Look for UHBR20 explicitly on the exact port specifications.
Basis: source-scoped interpretation. This classifies only the stated proposition, not an entire equipment pairing.
VESA permits DisplayPort 2.1b device certification without UHBR support, subject to its specified minimum and feature requirements. The version label therefore does not establish UHBR20 capability.
Version-versus-rate distinction; no detailed compliance certification performed here.
VESA describes DP80 for four-lane UHBR20 operation and says original DP40-certified cables are validated for the DP54 performance rating.
Cable-class observations; device lane/rate support and exact certification remain separate.
Excluded in stated scope · not hardware tested
VESA says no image is received when the port lacks DisplayPort over USB-C.
Still unknown. USB graphics adapters and their drivers are a separate solution class.
Next check. Find a documented video-capable output or a separately qualified graphics solution.
Basis: explicit source exclusion within stated native path. This classifies only the stated proposition, not an entire equipment pairing.
VESA states that an Alt Mode display receives no image when connected to a USB-C port that does not support DisplayPort over USB-C.
Native DisplayPort Alt Mode path only; USB graphics devices are a different technology.
Excluded in stated scope · not hardware tested
HDMI LA states that reversing the source/sink ends of its described active-cable path does not work.
Still unknown. This is not a claim about passive cable direction or all converter types.
Next check. Read both end labels before installing a long cable run.
Basis: explicit source exclusion within stated cable class. This classifies only the stated proposition, not an entire equipment pairing.
HDMI Cable Power requires support from both the active cable and the HDMI source. HDMI LA specifies source/sink direction for active cables and a separate power connector for sources without Cable Power support.
HDMI Cable Power feature scope; follow the exact cable’s instructions. Not monitor power or a universal converter-power rule.
Not established · not hardware tested
The described adapter class has a USB-C video source and HDMI destination; reverse operation is not established.
Still unknown. A reverse converter’s model, timing and power evidence is missing.
Next check. Find a converter explicitly documented for HDMI source → USB-C display.
Basis: direction-limited inference; not blanket product exclusion. This classifies only the stated proposition, not an entire equipment pairing.
VESA describes USB-C to HDMI accessories as DisplayPort Alt Mode protocol converters, with the USB-C end attached to the video source.
Described converter class and direction; do not assume passive rewiring, reverse operation or HDMI Alt Mode.
Earlier capability-library bookmarks remain available below; the table and cases above use the newer source-scoped observations.
