DisplayPort to HDMI Adapter with USB Audio - Works with DP++ Sources

In this review the DisplayPort to HDMI Adapter with USB Audio is evaluated for users who need to connect a DisplayPort equipped PC to an HDMI TV or projector while carrying audio. The adapter's single purpose is straightforward: provide a reliable passive DP++ connection and route audio via a USB connection when the DisplayPort source does not supply HDMI audio. For someone using desktop systems such as Dell OptiPlex models or other DP equipped machines, this adapter delivers a simple plug-and-play path to an HDMI display at common computer resolutions.

Key Features

• Display connectivity: Lets a computer with a DisplayPort output connect to an HDMI display so a monitor, TV or projector can be used without replacing the source device.
• USB audio support: Provides audio over USB so systems that do not forward HDMI audio from the DisplayPort can still output sound to the HDMI display.
• DP++ passive design: Uses passive single-link / dual-mode DisplayPort compatibility to avoid extra power or drivers on compatible video cards and desktops.
• Practical resolution support: Supports screen resolutions up to 1920x1200, making it suitable for typical office monitors, HDTVs and projectors at 1080p.
• Simple installation: No special software required; the adapter is intended for plug-and-play use on systems with passive DP++ outputs.

Who It's For

This adapter is aimed at desktop users and IT technicians who need a compact, reliable way to connect a DisplayPort output to an HDMI input, especially in meeting rooms or home office setups. It is a good fit for common business desktops such as Dell OptiPlex where DisplayPort is available but HDMI inputs are on the external display.

It is not intended for users who require 4K resolution, HDR, or high refresh rates for gaming; those users should look for an active converter rated for higher bandwidth. Likewise, devices without DP++ support will need an active adapter rather than this passive DP to HDMI solution.

Pros & Cons

Pros

• Simple, passive DP++ design works without extra power or drivers on compatible systems.
• USB audio option resolves audio passthrough issues when the DisplayPort output does not supply HDMI audio.
• Supports common display resolutions up to 1920x1200, covering most office and presentation needs.
• Compact and easy to carry for IT or travel use.

Cons

• Limited to single-link resolutions; it does not support 4K or higher bandwidth features.
• Requires a USB connection for audio on systems that do not forward audio over DisplayPort.

Specifications

Our Verdict

The DisplayPort to HDMI Adapter with USB Audio is a practical, no-frills solution for connecting DisplayPort equipped desktops to HDMI displays when audio passthrough is uncertain. It is good value for office, classroom and presentation environments where 1080p or 1920x1200 resolution is sufficient, and where a small, passive adapter with optional USB audio is preferred over larger active converters.

Frequently Asked Questions

Will this adapter carry audio without USB?
The adapter relies on DP++ audio from the source; if the DisplayPort output does not provide HDMI audio, use the USB connection to carry audio to the display.
