USB-C to DisplayPort Adapter for High-Resolution

This adapter connects a USB-C or Thunderbolt 3 host to a DisplayPort monitor at up to 8K 60 Hz with DSC or 4K 60 Hz without compression. It suits professionals who need a single-cable video link from thin-and-light laptops or workstations. The 12-inch attached cable keeps the desk tidy while reaching nearby panels.

DisplayPort 1.4 HBR3 Limits and Host Requirements

The link runs at HBR3 rates and relies on the host to supply DisplayPort Alt Mode video. An Intel 11th Gen processor with DSC support or a newer equivalent is required for the full 8K 60 Hz mode; older hosts fall back to lower resolutions. Maximum display distance is 6.6 ft, and the adapter carries two-channel audio alongside video.

Compact Dongle Build with Fixed Cable

The gray housing measures 0.60 by 15.40 by 1.50 inches and weighs 0.06 lb, so it adds minimal bulk to a travel kit. A 24-pin USB-C plug and a 20-pin DisplayPort connector lock securely without thumbscrews. HDCP 2.2 and 1.4 compliance allows protected content playback on tested Dell, Samsung and Asus monitors across Windows, macOS and Linux.

Questions about this item

How do I know whether my USB-C port can run 8K 60 Hz through this adapter?

Your host must provide Intel 11th Gen or newer graphics with Display Stream Compression support; otherwise the adapter falls back to 4K 60 Hz.

What does the 7680 × 4320 at 60 Hz spec actually deliver on a typical monitor?

It sends an 8K 60 Hz signal when the host GPU supports DSC over DisplayPort 1.4 HBR3; without DSC the maximum drops to 4K 60 Hz.

Does the DisplayPort 1.4 HBR3 link cap bandwidth or colour depth in real use?

HBR3 provides enough bandwidth for 8K 60 Hz with DSC or uncompressed 4K 60 Hz at 8-bit colour; 10-bit 4K 60 Hz would exceed the link.
