Run a longer HDMI cable to a loss of quality?
- Lengths of 10 or 20 meters are for the loss-free Transmission with HDMI cables, not a Problem in theory, as long as the quality is right. The cables are of inferior quality, often increases the rate of loss of length of the cable.
- The operating voltage of HDMI cables is 3.3 volts. The margin of Tolerance is quite low: Only 5 percent of the deviation of said voltage are allowed.
- Many devices such as a TV or DVD Player, take advantage of this margin of Tolerance already, thus, not exactly the 3.3 Volt voltage. A single damaged contact is added to this circumstance, still, it is irritating to the tolerance too much, so that the quality decreases. Such damage is caused by slight corrosion or abrasion by the connecting and Disconnecting of the cable.
- The longer the cable, the more it can deviate from the actual voltage to the level required. Thus, losses in quality occur. With well-manufactured cables that will not happen, however, in the rule.
- Conclusion: when buying a longer HDMI cable necessarily on the quality of the cable. The is not only on price but also on the customer reviews. Several customers report the case of a cheap cable no losses, you can access it there as well.
