DisplayPort 1.4 to HDMI 4K120Hz/8K60Hz Active Adapter - HighRes Bridge

Our review of the Club 3D CAC-1088 finds it to be a purpose-built adapter for users who need reliable high-resolution video from a DisplayPort source to an HDMI display. The single biggest reason to buy is straightforward: it reliably converts DP1.4 to HDMI while supporting up to 4K at 120Hz and 8K at 60Hz with HDR support, making it an easy way to connect modern gaming PCs and media players to high-refresh or high-resolution HDMI displays without extra power or drivers. Its plug-and-play simplicity and support for advanced HDR and HDCP standards are the main draws.

Key Features

• Display support: Enables connection to HDMI displays capable of 4K120Hz or 8K60Hz so users can take advantage of high-refresh gaming or high-resolution playback.
• DP1.4 with DSC: Uses DP1.4 DSC video compression technology to preserve image quality when converting signals, improving color and detail reproduction on compatible screens.
• HDR and metadata: Supports Dynamic metadata HDR10+ so HDR-enabled content can maintain dynamic tone mapping on compatible TVs and monitors.
• HDCP compatibility: Works with HDCP 1.4 and HDCP 2.3 to ensure most protected streaming content plays without handshake issues.
• Plug-and-play setup: No external power, software, or drivers required, making the adapter simple to install and use for most setups.
• High-performance targeting: Built for gamers and digital creators who need the highest-quality video output from a DisplayPort-equipped system.

Who It's For

The CAC-1088 is aimed at PC gamers, digital artists, and home theater enthusiasts who run systems with DisplayPort outputs and want to use HDMI 2.1-class displays at high refresh rates or resolutions. If you own an HDMI display rated for 4K120Hz or 8K60Hz and want a compact, no-fuss adapter that supports HDR10+ and modern content protection, this is a practical choice.

People who should look elsewhere include users requiring guaranteed VRR support across every monitor or those who need an adapter with an external power option for unusually long cable runs. Also, if your workflow depends on vendor-specific features not listed here, confirm compatibility before buying.
