A 20-metre HDMI 1.4 cable that carries Full HD 1080p video and audio from a distant source to a projector, TV or stage screen. It is tested before every rental, so it just works on the day.
This is a 20-metre HDMI cable built to the HDMI 1.4 standard, branded VCOM, with full-size HDMI Type-A male plugs on both ends.
It carries picture and sound on a single lead, so you do not need a separate audio cable running the length of the room. The headline is Full HD 1080p, and that is the honest target for a run this long.
HDMI 1.4 can technically carry 4K at 30Hz, but 20 metres is near the practical limit of a passive copper cable, so the steady, dependable result is 1080p from end to end.
Twenty metres is a lot of cable, and it exists to solve one problem: reaching a display that sits far from the source.
Think of a laptop at a control desk feeding a projector on the far side of a hall, or a media player driving a screen mounted high on a stage.
Because the run is long, the signal has further to travel, so image quality is best held at 1080p. For a demanding source over the full length, a signal booster or an active repeater can help hold a clean picture.
Both ends still need a full-size HDMI port, and the source and display devices are not part of the rental. If you need native 4K, a shorter HDMI 2.0 cable is the right choice instead.
