Description
HDMI 2.0 cables rated for 4K, in the lengths a classroom actually needs — short runs from a laptop to a display, longer ones from a wall plate to a ceiling projector.
What they are:
- HDMI version 2.0, 4K capable
- Available in 1m, 2m, 3m and 5m
Choosing a length: 1m and 2m for a laptop on a desk or trolley to a nearby display; 3m for a wall-mounted screen; 5m for a ceiling-mounted projector or a run through cable trunking. Measure the actual path, not the straight line — cables that follow a wall and a ceiling need more than you'd think.
Worth keeping spares in the AV cupboard — a missing HDMI lead stops a lesson as effectively as a broken projector. Bulk quantities available on a school purchase order.
