When installing an HDMI system, you must choose a high-quality cable that is compatible with your device. If the cable is too short, the quality of the signal will be compromised. In addition, too long cables may be difficult to run through walls and ceilings. If you’re not sure what length you need, it’s important to ask a professional. Most people will purchase black HDMI cables, but you can also get other colors and designs.
In general, HDMI cables have a maximum length of 15 meters. Typically, cheaper cables have the same quality as higher-priced ones. Because the signals are fully digital, they won’t suffer from signal dropoffs. In fact, some HDMI cable brands feature a ten-meter cable that’s only rated for three meters. It’s important to choose a high-quality HDMI cable to avoid a signal dropout.
If you’re installing a 4K display, make sure you buy an HDMI cable that supports HDR. A ten-foot-long cable with the correct TMDS rating can support 120Hz gaming and 4K video. An HDMI cable with a lower TMDS rating will not work with 120Hz displays. If you’re using the HDMI connection in a home theater system, a three-meter HDMI cable can be helpful.
