HDMI Cable Helos 288399 3m HDMI Type A Standard Black Grey

The Helos 288399 HDMI cable is a 3 m HDMI Type A to Type A lead designed for connecting TVs, monitors, projectors and AV receivers. It supports HDMI 2.0 features including 3D and Audio Return Channel (ARC), and uses gold-plated contacts to help maintain reliable signal transfer. The cable arrives in a black and grey finish intended to blend with home entertainment setups.

Advantages

The 3 m length provides flexibility for routing between devices without strain. HDMI Type A connectors on both ends ensure compatibility with a wide range of consumer electronics that accept standard HDMI plugs. Support for HDMI 2.0 and 3D enables higher bandwidth content and stereoscopic video where supported, while ARC allows audio to be sent from a TV back to an AV receiver or soundbar over the same cable. Gold-plated contacts are used to reduce corrosion and support consistent electrical contact.

• Connecting Blu-ray players, game consoles and media players to HDTVs or monitors
• Linking set-top boxes or streaming devices to TVs
