DisplayPort to HDMI Cable Adapter DP to HDMI, 20 ft - 1080p

In this review of the Tripp Lite DisplayPort to HDMI Cable Adapter (20 ft) the bottom line is simple: this cable is a practical, no-fuss way to drive an HDMI monitor or TV from a DisplayPort computer when you need length and straightforward compatibility. It is best suited to systems with Dual Mode DisplayPort (DP++) outputs and users who want reliable 1080p video and audio over a single, long cable without adding a separate dongle. The main reason to buy is the cable's convenience and full audio/HDCP passthrough across a 20 ft run.

Key Features

• 20 ft length: Allows the computer to be placed well away from an HDMI display or projector while maintaining a tidy installation.
• 1080p video support: Delivers high-definition video up to 1920 x 1080 for clear presentations and video playback on larger screens.
• Passive DP++ design: Works with Dual Mode DisplayPort sources so you do not need a powered converter when the graphics card supports DP++.
• Audio and HDCP passthrough: Transmits stereo audio (when the DisplayPort output provides audio) and supports HDCP for protected content playback.
• Durable connectors: Nickel-plated DisplayPort and gold-plated HDMI contacts improve signal reliability and resistance to corrosion.

Who It's For

This cable is aimed at office and classroom users, digital signage installers, and home users who need to connect a DisplayPort-equipped laptop or desktop to an HDMI monitor, projector or TV over a 20 ft distance. It is especially useful when the priority is a single cable solution that carries video and audio and supports HDCP.

It is not the right choice for systems without Dual Mode DisplayPort (DP++) support or for users who need resolutions above 1080p such as 1440p or 4K. If you require an active converter for non-DP++ sources or long runs with higher bandwidth needs, look for an active adapter or a cable rated for higher resolutions.

Pros & Cons

Pros

• Reliable 1080p video and audio passthrough when used with DP++ sources.
• Long 20 ft length gives installation flexibility for displays and projectors.
• Solid build details like nickel-plated and gold-plated connectors help connection stability.

Cons

• The passive DisplayPort end depends on DP++ support; it will not convert signals from non-DP++ sources.
• Some users have reported durability issues with the DisplayPort end breaking under strain, so gentle handling is advised.

Our Verdict

The Tripp Lite 20 ft DisplayPort to HDMI cable is a sensible, value-focused option for anyone who needs to extend a DP++ computer to an HDMI display at 1080p with audio and HDCP support. It covers common office and home setups well, but buyers should confirm their graphics output supports Dual Mode DisplayPort and handle the DisplayPort end carefully to avoid strain-related damage.
