DisplayPort 1.4 to HDMI 2.1 Adapter - 4K@120Hz 8K@60Hz Support

Our review of this DisplayPort 1.4 to HDMI 2.1 adapter examines who needs a simple, reliable way to connect a modern GPU or DP1.4 source to a new HDMI 4K120Hz or 8K60Hz display. The bottom line: it is a focused, single-purpose converter that brings DP1.4 DSC output to HDMI displays with support for 8K@60Hz and 4K@120Hz, making it a straightforward upgrade path for users with RTX 30-series or RDNA2 class cards who want high refresh rates or HDR on an HDMI-only monitor or TV.

Key Features

• DP1.4 to HDMI 2.1 conversion: Converts a DisplayPort 1.4 source to HDMI so newer HDMI displays can receive high-resolution, high-refresh signals from a DP output.
• High resolution support: Handles resolutions up to 8K 7680x4320@60Hz or 4K 4096x2160 at higher refresh rates when DSC is available, delivering sharper detail for large displays.
• DSC video compression: Uses DisplayPort 1.4 DSC v1.2a to enable higher resolutions and refresh rates over HDMI while preserving image fidelity and HDR metadata.
• HDR and surround sound: Supports Dynamic HDR and multichannel audio formats like 5.1-7.1, so movies and games retain color depth and immersive sound on compatible displays.
• Multi-screen support: Active DP HDMI adapter is compatible with AMD Eyefinity and SLS modes, allowing connection patterns that can extend to multiple screens when supported.
• Mirror and extended modes: Works for mirrored displays or extended desktops, useful for gaming on a TV or adding an extra workspace monitor.

Who It's For

This adapter is aimed at PC owners with a DisplayPort 1.4 output who need to connect to an HDMI display that supports HDMI 2.1 features such as 4K@120Hz or 8K@60Hz. Gamers upgrading to high-refresh TVs, content creators using large HDR displays, and anyone who wants an easy one-cable conversion from DP to HDMI will find it useful.

It is not for users who need a bi-directional cable; the adapter only converts DisplayPort source signals to HDMI displays. Also, if your source device is limited to DisplayPort 1.2 or your TV firmware and GPU drivers do not support DSC, you will not get the highest resolution or HDR benefits.

Pros & Cons

Pros

• Supports high-end display modes like 8K@60Hz and 4K@120Hz when DSC is available, unlocking advanced HDMI displays.
• Maintains HDR and multichannel audio support for a complete media experience.
• Works with mirror and extended desktop setups and supports AMD Eyefinity multi-display configurations.
• Compliant with VESA DP1.4 and HDMI specifications for broad device compatibility.

Cons

• Not bi-directional: it will not convert HDMI source signals to DisplayPort displays, which limits some use cases.
• Requires DP1.4 DSC support and up-to-date TV firmware and GPU drivers to achieve the highest resolutions and refresh rates.

Our Verdict

This DisplayPort 1.4 to HDMI 2.1 adapter is a practical, value-focused solution for users who need to bridge a DP1.4 output to a modern HDMI display and want access to 8K@60Hz or 4K@120Hz modes with HDR. It delivers on its core promise when the GPU and TV firmware support DSC, but buyers should verify DP1.4 and DSC compatibility on their devices before relying on the top-end features.

Frequently Asked Questions

Can I use this adapter in reverse?
No, this adapter is not bi-directional and only converts a DisplayPort source to an HDMI display.

Do I need to update anything to get 8K or 4K@120Hz?
Yes, update your TV firmware and GPU drivers and ensure your source supports DisplayPort 1.4 with DSC v1.2a to enable the highest resolutions and refresh rates.

Will HDR work with older DisplayPort versions?
HDR requires DP1.4; legacy DisplayPort 1.2 does not support HDR through this adapter.
