Resolving 3m HDMI Cable Frequency Loss
As a rule, the shorter the distance a video signal has to travel through an HDMI cable, the better picture and audio quality you will get. All cables generate electrical resistance which affects the overall signal quality. However, you won’t likely detect any difference in video quality whether you use a 2m or 3m hdmi cable, but if you will use a sensitive testing device to measure the signal output, there would be a very slight difference.
To address this issue, cable manufacturers came up with gold-plated connectors to ensure better connection and enhanced audio/video signal transfer. Gold plating the connectors minimizes electrical resistance, which means that there is little or no frequency loss, which is crucial for high-definition transmissions.
If you are considering using 3m cables with gold-plated connectors, then it can cost you more than using an HDMI cable with standard metal connector. If you are prepared to deal with the increase in price, then you might as well invest in a high-quality gold-plated connector because superior quality gold plating produces less resistance.
If you want excellent video quality, choosing a 3m cable with superior quality gold-plated connectors will more likely deliver the same video quality as a 2m HDMI cable that comes with cheaper gold-plated connectors.
