Mini DP 1.4 cable for 8K displays

This VESA-certified Mini DisplayPort 1.4 cable connects laptops or desktops with Mini DP or Thunderbolt ports to standard DisplayPort monitors. It supports 8K at 60 Hz, 5K at 60 Hz, 4K at 144 Hz and 2K at 240 Hz with 32.4 Gbps HBR3 bandwidth. HDR10, Dolby Vision and 10-bit deep colour are carried alongside Dolby Atmos and 32 audio channels. The 3.3 ft length suits typical desk setups.

Upgrade from older DP cables for high refresh

Replaces DisplayPort 1.2 or 1.1 cables that limit 4K to 60 Hz or 1440p to 144 Hz. The jump is worth it when your monitor and GPU both support DSC 1.2, VRR, G-Sync or FreeSync at 4K 144 Hz or 1440p 240 Hz. Backward compatibility with DP 1.3, 1.2, 1.1 and 1.0 keeps older screens working, but they cannot reach the new resolution and refresh combinations.

Limited by DisplayPort 1.4 specification

Maximum bandwidth is fixed at 32.4 Gbps, so 8K 60 Hz requires DSC compression and 8K 120 Hz is not possible. HDCP 2.2 protects premium content but adds handshake steps that can fail on very long runs. The cable is bi-directional, yet the Mini DP end must match the source port; it will not fit full-size DisplayPort outputs without an adapter. Audio formats above 7.1 channels are not defined in the standard.

Questions about this item

What size Mini DisplayPort and DisplayPort connectors does this cable use?

It uses a standard Mini DisplayPort plug on one end and a full-size DisplayPort plug on the other, both with gold-plated contacts for reliable signal transfer.

How do I connect this bi-directional cable between my MacBook and monitor?

Plug the Mini DisplayPort end into the MacBook's Mini DP or Thunderbolt 2 port and the full-size DisplayPort end into the monitor; no driver installation is required.

How often should I replace this cable to maintain 8K 60 Hz performance?

The cable is passive and has no wear-out components; replace it only if the connectors are damaged or the signal becomes unstable.
