40 ft HDMI 1.4 Cable

The StarTech HDMM40 is a 40-foot male-to-male HDMI cable built to the HDMI 1.4 specification. It carries both digital audio and video signals between two standard HDMI ports without requiring an external signal booster. Gold-plated contacts and moulded strain-relief connectors are fitted at each end. The cable is finished in black.

Installers Needing Long Reach

This length suits installers who must bridge a 40-foot gap between a source such as a laptop and a display such as a projector. It is not suited for setups that require 4K resolution at 60 Hz or any feature defined in later HDMI versions. Buyers needing longer runs or higher refresh rates should consider active or fibre-optic alternatives.

4K at 30 Hz Maximum Resolution

The cable supports Ultra HD resolutions up to 3840 x 2160 at a 30 Hz refresh rate. This single bandwidth limit determines whether the cable matches the display and source capabilities in a given installation.

Questions about this item

Should I choose this 40 ft length or a shorter cable for my 4K 30Hz setup?

The 40 ft length works at the full 3840x2160 30Hz rating without a booster; pick a shorter cable only if the run is significantly less than 40 ft to reduce clutter.

Will this cable actually deliver 4K at 30 Hz on my laptop and projector?

Yes, the HDMI 1.4 link supports 3840x2160 at 30 Hz end-to-end, so a laptop and projector both limited to that rate will display the full resolution.

What does the HDMI 1.4 interface limit in practice?

HDMI 1.4 caps the signal to 3840x2160 at 30 Hz and standard audio formats; higher refresh rates or 4K 60 Hz need a newer interface version.
