Description

StarTech 148B-HDMI-DP-8K HDMI to DisplayPort Adapter Cable

Overview

The StarTech 148B-HDMI-DP-8K is an active adapter cable designed to convert an HDMI 2.1 output signal to a DisplayPort 1.4 signal. This is crucial for connecting newer HDMI 2.1 sources, such as advanced workstations or media players, to displays or monitors that only feature DisplayPort 1.4 inputs. It supports resolutions up to 8K at 60Hz, ensuring high-fidelity video transmission for demanding applications like video walls or high-resolution surveillance monitoring stations. The 1-foot (30cm) cable length minimizes signal degradation and clutter in tight installations.

Compatibility

This adapter is compatible with any HDMI 2.1 source device. The output is DisplayPort 1.4, making it suitable for connecting to monitors, projectors, or input cards that support the DisplayPort 1.4 standard. It supports 2-channel audio over DisplayPort. The active chipset ensures signal conversion without requiring a DP++ (dual-mode DisplayPort) output from the source, which is common on many graphics cards and devices.

Installation Notes

The adapter requires power via its USB Micro-B port, which can be sourced from a nearby USB port on the host device or a separate USB power adapter (not included). This USB power is essential for the active chipset to perform the HDMI to DisplayPort conversion. Operating temperature is between 0°C and 40°C (32°F to 104°F).
