A Quick Guide to AV (Audio Visual) Connectivity

Traditionally we have connected computers to display devices using VGA (15pin D-type) connectors. Audio, if required, was connected through RCA phono or 3.5mm mini-jack. This is still very common and indeed many laptops/notebooks currently only provide this option. Over the years, image resolution has been increasing and as a result we are able to display crystal clear graphical content and razor sharp presentations. As resolution has increased, the shape of our content has moved from traditional ‘square’ 4:3 to widescreen HDTV 16:9.

Latest AV Connectivity – HDMI

The newest offering for best quality video is HDMI (high-definition multimedia interface). HDMI sends picture & audio down one cable and can deliver higher resolution ‘High Definition’ signal to a HD display. With tablets, portable devices and Smartphones omnipresent, wireless connectivity is becoming more common. Wireless presentation devices can be attached to displays which allow you to wirelessly connect one or multiple devices to a single display. This technology should be well tested in advance of any event and some tablet device functionality may be limited. Wired HDMI signal is typically limited to 15 mtr. Cables, however, signal can be distributed over much larger cable runs using video processors.
