DisplayPort 1.2a to 4K HDMI Active Adapter

This active adapter connects a DisplayPort source to an HDMI display. It supports resolutions up to 3840x2160p at 30Hz. The unit works with AMD Eyefinity and NVIDIA Surround multi-display modes. It is built to the DisplayPort 1.2a standard.

Compatibility checklist

Verify that your source device has a standard DisplayPort output. The adapter requires no external power and draws from the port itself. Ensure the target display accepts an HDMI input capable of 4K at 30Hz. The connector heads measure 14.5 x 25.5 x 31.0 mm and 17.5 x 27.5 x 47.0 mm.

Thermals and power

Passive components mean zero fan noise during operation. Power consumption is negligible and sourced directly from the DisplayPort connection. The short 5 inch cable and polycarbonate housings add no measurable heat to the setup. Normal use stays well within the port's current limits.
