Trouble-shooting tips for long HDMI cables

High Definition Multimedia Interface (HDMI) is an interface provided by cables which allows for the high speed transmission of audiovisual signals. Sometimes you may need to connect devices at a distance from the source of the digital data.

An HDMI cable transmits data at speeds in excess of 10.2 gigabytes per second, without converting it to analog. HDMI retains the original digital nature of the signal producing crystal clear picture and sound quality.
An HDMI cable can accommodate up to 8 audio channels at one time. Here we have discussed the troubleshooting of problems encountered in using long HDMI cables.

Long HDMI cables – Diagnose and repair

An HDMI cable may not be so effective at distances beyond 50 feet. You may find HD cables in the market which are optimised for proper transmission even beyond 50 to 100 feet. However, in these cases you will most certainly require a signal booster and an equalizer. The equalizer enhances the signal quality and the booster pushes the enhanced signal across the distance.

The first effective step to knowing whether it works or not, is to simply try it out. In most cases a long HDMI cable will work well but the performance cannot be guaranteed. The booster will be needed for better performance. Even if you buy two different cables with the same specifications from one manufacturer you may find differences in performance. Some believe to have a long HDMI cable working well for you is a matter of luck.

In most cases the screen will not display any images. Try transmission with an equalizer and a booster assembly for proper diagnosis of the problem. Buy from a retailer who will allow an exchange in case the cable does not work well.
