This super VGA extension lead is known as the best in the industry.
The lead is made in the premium 3x RGB Coax plus 9 wiring configuration, which can minimise the quality loss inlong distance.
Two ferrite filters at both ends also reduce any video interference.
Having hum issue when using the cable?
Please make sure that both VGA and Audio plugs are plugedcorrectly and connected properly into your device. Only using one plug will creat groud loop issue which results in hum.(eg. Only connecting vedio or VGA to projector and 3.5mmaudio plug to seperate active speakers)
Please use seperate cables If you are connecting seperateaudio and video devices.
