One-cable 8K link

The StarTech CDP2DP146B is an active USB-C to DisplayPort 1.4 adapter cable that carries 7680×4320 at 30 Hz over a single 1.8 m run. It draws power from the host port and supports 7.1 surround sound, so creative pros and digital-signage installers get video and audio without extra cords.

Replaces separate cable plus dongle

A passive cable cannot drive 8K at HBR3 bandwidth; this active adapter adds the required signal conditioning inside the plug. The jump is worth it when your source supports DP Alt Mode and you need 32.4 Gbps throughput for 8K 30 Hz or high-refresh 4K without signal degradation.

Fits USB-C hosts with DP Alt Mode

The host port must expose DisplayPort alternate mode; Thunderbolt 3 ports qualify, but plain USB-C data ports do not. The 5.9 ft length reaches desktop monitors from a dock or laptop without slack, and backward compatibility with 1080p and 4K displays lets you reuse existing screens while the adapter stays in place for future 8K panels.

Questions about this item

Does the 1.8 m cable reach my monitor without extra cabling?

The 1.8 m length provides a direct USB-C to DisplayPort connection so no separate cable is needed.

My laptop only has a USB-C port — will this adapter work without drivers?

Yes, it uses plug-and-play installation; just ensure the USB-C port supports DP Alt mode.

How long before the active circuitry in this adapter might need replacement?

The active adapter has no moving parts or user-serviceable components, so it typically lasts the life of the cable.
