Bidirectional USB-C DisplayPort cable

This active cable carries video and 7.1-channel audio between a USB-C source and a DisplayPort monitor or the reverse. It requires the USB-C port to support DisplayPort Alt Mode and works with Thunderbolt 3 hosts. The one-metre length suits desktop setups without excess slack.

Sustained 8K 30Hz bandwidth

HBR3 signalling delivers up to 32.4 Gbps continuously, allowing stable 7680 x 4320 resolution at 30 Hz for extended sessions. The Chrontel CH7213C-BF, Texas Instruments TUSB544 and VIA Labs VL170 chipsets maintain link integrity without the dropouts seen on passive cables at full rate.

Passive thermals and silent operation

No onboard fan or active cooling is present; the adapter draws power from the host port and runs silently. Power consumption stays within the USB-C or Thunderbolt 3 supply budget, adding negligible heat to the workstation.

Questions about this item

Does the CDP2DP141MBD run warm or draw extra power when driving an 8K 30Hz signal all day?

The active cable uses Chrontel, Texas Instruments and VIA Labs chipsets to handle HBR3 bandwidth up to 32.4Gbps. It draws bus power only and has no fan, so it stays cool during continuous 8K 30Hz use.

My laptop only has a Thunderbolt 3 port — is that enough for the CDP2DP141MBD to work?

Yes. The cable is Thunderbolt 3 compatible and requires a USB-C port that supports DisplayPort Alt Mode. A Thunderbolt 3 port provides both, so no extra adapter or dock is needed.

Can I keep my older DisplayPort 1.2 monitor and still use the CDP2DP141MBD with a new USB-C laptop?

Yes. The bidirectional cable supports DisplayPort 1.4 and falls back to earlier revisions, so a DisplayPort 1.2 monitor will work at its native resolution and refresh rate.
