Active DP 1.4 to HDMI 2.1 Adapter

This active converter uses a CH7218 chip to translate DisplayPort 1.4 output into a full HDMI 2.1 signal. It targets gamers and creators who need 8K@60Hz or 4K@144Hz from a GPU that only offers DisplayPort connectors. The adapter supports HDR, VRR and ALLM for modern gaming monitors and TVs. No external power supply is required for typical desktop use.

Upgrading from passive adapters

Passive DisplayPort to HDMI dongles are often limited to lower resolutions or refresh rates and cannot pass the full 48Gbps bandwidth. This active unit removes those restrictions, enabling 8K@60Hz and 4K@144Hz where passive models fail. The jump is worth it when your display demands HDMI 2.1 features such as variable refresh rate or auto low latency mode. It also solves compatibility issues with certain graphics cards that refuse to drive passive dongles at high speeds.

Installation and common issues

The adapter is plug and play; simply connect it between the GPU DisplayPort and the display HDMI cable. Most systems recognise the link instantly without driver installation. Problems usually arise if the source port does not supply enough current for the active chip, causing signal dropouts at 8K or high refresh rates. Using a certified 48Gbps HDMI cable and keeping the total cable run short reduces the chance of instability.

Questions about this item

Does the CH7218 adapter need an external power supply?

No extra power supply is required for normal operation in most usage scenarios.

How do I connect the CH7218 adapter to my graphics card?

Plug the DisplayPort 1.4 end directly into the GPU's DP port and the HDMI 2.1 end into the display; it works plug-and-play without driver installation.

Will the CH7218 chip or adapter need firmware updates later?

The adapter operates without driver installation and has no user-serviceable firmware, so no updates are required.
