The adapter supports video and audio transmission and is specified to handle resolutions up to 4K, enabling connection of laptops, desktops or graphics cards to monitors, TVs and projectors without requiring external power. Its small form factor and plug-and-play operation simplify temporary or permanent multi-device setups where an HDMI input is required.

Advantages

This passive DisplayPort to HDMI adapter offers a simple, no-power solution for connecting a DisplayPort output to HDMI-equipped displays. It supports native audio pass-through along with video up to 4K resolution, reducing the need for additional cables or converters. The adapter's compact design makes it easy to carry and position behind devices, and its passive nature avoids extra power supplies or drivers for most compatible sources.

Suitable for

• Connecting laptops with DisplayPort to HDMI monitors or TVs
• Attaching desktop graphics cards with DisplayPort outputs to HDMI projectors

How to use

Insert the DisplayPort end into the DisplayPort output on your laptop, desktop or graphics card, then connect an HDMI cable from the adapter's HDMI end to the HDMI input on your monitor, TV or projector. Ensure the source device is set to output via DisplayPort and select the correct HDMI input on the display. Most systems will detect the connection automatically and configure resolution and audio routing; adjust display resolution in the operating system or graphics driver settings if needed.

Usage recommendations

For optimal results, use high-quality HDMI cables rated for the intended resolution. When targeting 4K resolution, verify that both the source device and the display support 4K output and that the operating system or graphics driver is configured to allow 4K output. If audio is not detected, check the source device's audio output settings and update graphics drivers if necessary.
