Target device and resolution support

This USB-C to DisplayPort adapter connects a USB-C or Thunderbolt 3 host to a DisplayPort monitor at up to 7680 x 4320 resolution at 60 Hz. It is suited for users who need 8K output from a laptop, tablet or desktop with a DisplayPort Alt Mode port.

Bandwidth and feature enablement

HBR3 bandwidth of 32.4 Gbps carries 8K 60 Hz, HDR and 7.1 channel audio through the DisplayPort 1.4 link. The adapter itself requires no driver installation and draws power from the host port.

Host port and cable length checks

Verify that your USB-C port supports DisplayPort Alt Mode and that the host GPU can drive the desired resolution. The adapter’s 0.9 in cable stub means the DisplayPort cable run to the monitor must not exceed 6.6 ft for reliable 8K signal integrity.

Questions about this item

Does the USB-C connector or the DisplayPort output wear out first with daily plugging?

The adapter has a 24-pin USB-C male input and a 20-pin DisplayPort female output; both are solid-state with no moving contacts, so neither side has a defined wear-out cycle.

What bandwidth ceiling caps sustained 8K 60Hz throughput?

HBR3 limits the link to 32.4Gbps, which is the maximum bandwidth this adapter can sustain for 7680 x 4320 at 60Hz.

Does the dongle get hot or draw extra power during all-day 8K output?

The unit is bus-powered from the USB-C port and has no active cooling; it runs at the host's supplied power with no separate thermal rating provided.
