8K USB-C to DisplayPort 1.4 Cable

This 3.3ft unidirectional cable connects a USB-C or Thunderbolt 3/4 source with DP Alt Mode to a DisplayPort monitor. It supports resolutions up to 8K at 60Hz and 4K at 240Hz with HDR and DSC. It is built for gamers and professionals who need high refresh rates from a compatible laptop or phone.

Bandwidth and resolution limits

The link runs at 32.4 Gbps using HBR3 and DSC 1.2, enabling 8K 60Hz 10-bit HDR, 5K 60Hz, 4K at 120/144/165/240Hz, and 2K at 240Hz. Both source and display must support the target resolution and refresh rate. The cable is backwards compatible with DP 1.3 and 1.2 but cannot carry video from a DisplayPort source to a USB-C screen.

Installation notes

Plug the USB-C end into the host and the DP end into the monitor; no driver is required. The built-in CYPD smart chip and 28 AWG tinned copper conductors stabilise the signal. Ensure the host port implements DP Alt Mode and that both devices share the desired mode, otherwise the link will fall back to a lower resolution or show no image.

Questions about this item

Should I pick the 3.3ft length or look for a longer cable?

The 3.3ft cable suits a desktop monitor placed close to the host; if your screen sits farther away you will need a longer run.

What does the 32.4Gbps bandwidth actually deliver on my monitor?

It enables up to 8K at 60Hz with 10-bit HDR, 4K at 240Hz or 165Hz, and 2K at 240Hz, provided both source and display support those modes.

Does the USB-C end work with Thunderbolt 3 and 4 ports?

Yes, the cable is compatible with Thunderbolt 3 and 4 hosts that offer DP Alt Mode, and it is backwards compatible with DP 1.3 and 1.2 displays.
