Right-angle HDMI adapter pack

The LUOM 4-pack supplies both 90 degree and 270 degree male-to-female HDMI changers. Each adapter lets you route a cable upward or downward when the port sits flush against a wall or tight cabinet. They suit media sticks, consoles, PCs and projectors where rear clearance is minimal. The gold-plated contacts preserve signal integrity across repeated insertions.

Signal performance and clearance

The adapters pass HDMI 2.0 bandwidth and support resolutions up to 4096x2160 and 3840x2160 alongside 2560x1600, 2560x1440, 1920x1200 and 1080p. They carry ARC, HEC, 48 bit colour, 32 channel audio and Dolby True HD 7.1 without added compression. HDCP compliance keeps protected content playing. The body extends less than one inch from the port, adding no measurable heat or power draw.

Build quality and daily use

A textured grip surface makes plugging and unplugging easy even in cramped AV racks. The right-angle geometry acts as a port saver by redirecting cable strain away from the host socket. Four units in the pack cover multiple devices such as a FireTV stick, Roku, Chromecast, Xbox, PlayStation or Switch simultaneously. No driver or firmware is required; the connection is purely passive.

Questions about this item

How do I install the 90-degree and 270-degree HDMI adapters on a wall-mounted TV with limited clearance?

Plug the male HDMI end into the TV port; the adapter extends less than 1 inch. Choose the 90-degree unit to route the cable downward or the 270-degree unit to route it upward, matching the port orientation.

What maintenance will the gold-plated connectors need over time?

Gold-plated contacts resist oxidation. If dust builds up, disconnect the adapter and use a dry compressed-air can to clear the ports; no lubricants or abrasive cleaners are required.

What is the first signal limit reached when running 4K at 60 Hz through these adapters?

The adapters support HDMI 2.0 bandwidth, so 4K 60 Hz 4:4:4 48-bit colour and 32-channel audio pass through; the first limit is the source or display device, not the adapter itself.
