When it comes to choosing an HDMI cable, you have several options. You can either get a shorter cable, which can be awkward in some circumstances, or a longer cable. However, there are a few things you should be aware of.
First, under ideal conditions, the quality of the signal transmission does not depend on the length of the cable. Second, conditions may not always be idea
Therefore, a long HDMI cable can have a negative effect on signal quality. Especially if the cable is of low quality.
Does the length of HDMI cable affect quality?
Yes, the length of the cable affects the quality of the signal. And it’s true. As I said, under ideal conditions, cable length should have very little effect on signal quality. And in expensive high quality HDMI cables, it really does. However, if you want to buy a cheaper HDMI cable, cable length will almost directly affect signal quality.
The thing is, the specifications for the cable usually do not specify the maximum length of the connection via HDMI. However, signal attenuation is often the result of using a cable that is too long. This is because signal quality is directly related to both the quality of the conductor and the quality of the cable itself. So if poor quality materials were used, the signal quality will be relatively poor.
What is the best HDMI cable length?
Now let’s talk about the ideal cable length (more precisely about the maximum cable length at which the quality of the signal will not deteriorate). Most experts agree that an HDMI cable should be 15 meters (about 50 feet) long in order to transmit the signal with maximum quality.
If you want to use a cable longer than 15 meters (50 feet), you may need signal restorers, equalizers, amplifiers, or you must use fiber optic cable.
