Mini DisplayPort 8K cable for laptops and desktops

This CableDeconn cable links a Mini DisplayPort source to a full-size DisplayPort display or works in reverse from a DisplayPort computer to a Mini DisplayPort monitor. It targets users who need 8K 60 Hz or 4K 144 Hz video on external screens for meetings, home theatre or gaming.

Bi-directional wiring replaces two separate adapters

The single 9.9 ft assembly carries signals both ways so one cable serves a Mini DP laptop driving a big monitor and a desktop driving a Mini DP panel. It supports DP Alternate Mode on the source side and requires the Mini DP display to be a true DisplayPort connector not Thunderbolt 1 or 2.

DisplayPort 1.4 bandwidth caps resolution

The 32.4 Gbps link allows 7680 x 4320 at 60 Hz or 3840 x 2160 at 144 Hz and is backward compatible with earlier DisplayPort versions. The cable carries only video so it cannot transfer data and true 8K devices remain uncommon on the market today.

Questions about this item

Will the DisplayPort 1.4 connectors on this 9.9 ft cable need replacement over time?

The gold-plated DisplayPort 1.4 connectors are rated for thousands of insertion cycles and should not need replacement under normal use.

What bandwidth limit appears first during sustained 8K 60 Hz output?

The cable is certified for the full 32.4 Gbps DisplayPort 1.4 bandwidth, so the host GPU or display controller will reach its limit before the cable does.

Does the 3 m length add noticeable heat or power draw during all-day 4K 144 Hz gaming?

The passive copper construction draws no extra power and generates no measurable heat, even during continuous high-refresh-rate sessions.
