Mini DisplayPort to DisplayPort 8K Cable

This three-metre cable connects laptops or desktops with a Mini DisplayPort output to monitors, TVs or projectors that use a full-size DisplayPort input. It supports bi-directional transmission, so the same cable can also carry video from a DisplayPort source to a Mini DisplayPort display. The link is compatible with Thunderbolt 1 and Thunderbolt 2 ports on MacBook models.

Sustained 8K and high-refresh 4K signalling

The cable is rated for DisplayPort 1.4 with a maximum bandwidth of 32.4 Gbps, allowing a stable 7680x4320 signal at 60 Hz or 3840x2160 at 144 Hz over the full length. Because the specification is met end-to-end, the link maintains these rates during extended gaming or video sessions without dropping to a lower mode.

DisplayPort 1.4 practical limits

The 32.4 Gbps ceiling defines the highest resolution and refresh combinations the interface can carry; 8K at 60 Hz and 4K at 144 Hz sit at that boundary. Bi-directional use requires the Mini DisplayPort sink to support video transmission, otherwise the reverse direction will not function. The cable is backwards compatible with earlier DisplayPort 1.4 implementations.

Questions about this item

Does the 3 m length add measurable latency or signal loss when running 8K at 60 Hz all day?

The cable is built to the DisplayPort 1.4 spec with 32.4 Gbps bandwidth, so the 3 m run maintains full 7680x4320@60Hz integrity without added latency or degradation during continuous use.

What ports must my laptop and monitor already have for this cable to work?

Your laptop needs a Mini DisplayPort or Thunderbolt 1/2 port and your monitor needs a standard DisplayPort input; both must support video output or input respectively for the bi‑directional link to function.

Will this cable drive my older 4K 60 Hz DisplayPort monitor from a Mini DP laptop without scaling issues?

Yes, the cable is backward compatible with DisplayPort 1.4 and lower, so it will carry 3840x2160 at 60 Hz cleanly from a Mini DP source to a standard DP display.
