What is AWG standard ?

AWG stands for American Wire Gauge. It relates to size, maximum frequency, the resistance of the conductor, and power-carrying capacity. A smaller AWG number of HDMI means a thicker conductor, less parasitic capacitance, more frequency range, less digital signal loss and less sensitivity to electromagnetic interference with other devices. The smaller the AWG number, the better. Typical HDMI cables are 28AWG for up to 10 metres and 24AWG for up to 20 metres. The quality of short HDMI cables is not critical. For lengths of 1 and 0.5 metres, AWG can be 30 without losing quality.

Expensive HDMI leads break TV sockets

There are a variety of HDMI leads available on the market. Some brands use shiny materials, thick shielding and insulation for better sales. While golden plugs look impressive, they're not better than cheap ones. Digital video and audio signals are transmitted efficiently regardless of the lead's appearance. But thick insulation adds extra weight to the HDMI socket in your device. This causes the connection to lose and eventually breaks your TV or other HDMI-connected devices quicker.
