How to Run HDMI Long Distances: The Basics
HDMI maxes out at 50 feet. This is not a hard, fast rule. Your HDMI signal depends largely on the amount of power your source device is putting out. Each device is different, therefore, your signal distance won’t be the same with every device. For example, most computers have trouble transmitting that signal over 30 feet. Most home theater devices fall pretty close to the 50 feet threshold, but again, this is not a hard and fast rule. A prime example is video game consoles, which typically max out at 20 feet. Your maximum distance may vary.
If your run is under 50 feet, depending on the device, you might still benefit from some type of signal booster or repeater. An HDMI repeater is used to connect two cables, then amplifies the signal to provide that final “oomph” it needs to transmit clearly.
If your run is over 50 feet, you most definitely will require some type of amplifier. You can use an HDMI repeater to join two cables together, or FireFold offers a 75ft HDMI cable and a 100ft HDMI cable with built-in equalizers. These equalizers amplify the signal at the display end to ensure the output signal is as strong as the input signal.
An HDBaseT setup will require both a transmitter and a receiver, with an Ethernet cable in between, so be sure you’re purchasing both. Some HDBaseT units are built into wall plates, allowing you to maintain a professional, finished look to your setup.
As you can see, long HDMI runs can be a bit tricky. But with a little research, you’ll find there are many options available. As always, those of us at FireFold are ready to help offer solutions!
