HDMI to DisplayPort Adapter with 4K Support - Reliable HDMI to DP

In this review the Cable Matters HDMI to DisplayPort adapter is judged on ease of use, compatibility and picture quality. It is aimed at users who need to connect an HDMI-equipped laptop or desktop to a DisplayPort monitor and want a straightforward, powered solution. The single biggest reason to buy is its active conversion with a USB power option that helps deliver a stable signal for extending a desktop or using a second monitor with up to 4K resolution.

Key Features

• Active HDMI to DisplayPort conversion: Converts HDMI output from a computer to DisplayPort input on a monitor so users can add a second display without changing the video card.
• 4K video support: Supports up to 3840x2160 at 30Hz and common lower resolutions at 60Hz for clear high-resolution output when the source supports it.
• USB powered for stability: Includes a USB power cable to boost the video signal and reduce dropouts when the HDMI source needs extra power for conversion.
• Wide laptop compatibility: Works with many HDMI-equipped laptops and desktops such as several Inspiron and HP 14 models, making it useful for typical office and home setups.
• Durable build: Gold-plated connectors and a sturdy housing are designed for frequent plugging and unplugging without obvious wear.

Who It's For

This adapter is best for users who have an HDMI-only computer and a DisplayPort monitor and want a plug-and-play way to extend their desktop or mirror the display. It is especially helpful for people who need occasional multi-monitor setups with laptops like Inspiron or standard HP models and want a simple cable adapter rather than a docking station.

Those who need true 4K at 60Hz, professional color-critical video work, or wireless display features should look elsewhere or verify their video card and monitor capabilities before buying, since the adapter supports 4K only at 30Hz and color accuracy depends on connected hardware.
