LORDWORLD HDMI 2.1 Male-to-Male 8K 60Hz Gold Adapter

HDMI 2.1 8K coupler for cable extension

This HDMI 2.1 male-to-male adapter joins two HDMI cables into a single longer run. It supports UHD 8K resolution at 60 Hz and handles HDCP and 3D signals. The gold-plated contacts and silver shield shell are built to maintain signal integrity across the connection. It is intended for installers and home-cinema owners who need to bridge a gap between existing cables.

Check cable ends and total run length

Before ordering, verify that both cables you plan to join have standard HDMI female ports. Confirm the combined cable length still meets the signal-quality requirements of your 8K 60 Hz source and display. The adapter adds no active amplification, so excessive total distance may degrade the picture. Ensure your devices negotiate HDCP correctly through the passive link.

Passive bridge that preserves bandwidth

The coupler sits between two cables and requires no external power. It passes the full HDMI 2.1 bandwidth needed for 8K 60 Hz, HDCP and 3D without compression. Gold contacts resist oxidation while the silver shield helps reject interference. It frees you from buying a single extra-long cable and lets you reuse shorter runs already in walls or conduits.
