As far as manufacturers are concerned, they can create a cable that can be longer than 50 feet just in case someone has to connect a player and a TV across the whole house. But who would want that? However, a consensus among manufacturers is that 20 feet is considered to be the maximum length of an HDMI cable if you want to retain the quality of the audio and the video. A little longer than this, and you just might ruin your own viewing and listening experience.
Why 20 feet? The rule here is that the shorter your HDMI cable is, the better the sound and video quality. Say, for some unknown reason, you need an HDMI cable that is beyond 20 feet.
What now? Again, this maximum is considered the optimal length to ensure proper signal transmission. Another option is to use a wireless HDMI kit. A wireless HDMI kit works like a wireless signal transmitter. It also allows you to plan how to set up new equipment when you know how long the cables are and how far apart everything can be from each other.
The industry will start off manufacturing what they feel are the lengths most people will end up purchasing based on their studies and knowing how specific equipment will be situated in a typical setup. For the most part, these lengths become the standard however, consumer demand often ends up dictating what the standard will be. You can identify these instances by the odd lengths of HDMI cables that start showing up on the market.
To me, these lengths do not fit the standard mold. Of course, you would need to have two identical setups running to test this out and honestly, who does this? There must be a way however, to run HDMI cables and keep the quality high and there is? Read on to find out more. If requested, new home builders are installing Cat6 wire in the walls before the walls are drywalled.
This means you only need an HDMI cable to be long enough to span from the device to the wall connection. These cables do not require an electrician to install so you can go ahead and fish Cat6 cables through your wall, if you want to modernize your networking system. There is conflicting information online regarding when and why lag appears when using long HDMI cables. How long can an HDMI cable be?
It depends on how it's made and what resolution your content is. The longer an HDMI cable is, the more signal it loses due to attenuation , which is why it needs to be made with a thicker gauge, officially known as its AWG rating; its American Wire Gauge.
The lower a cable's AWG rating, the thicker its gauge and the better equipped it is to deliver a high-resolution signal over longer distances. For example, a thin cable won't be able to transmit a 4K signal as long as a p signal. If you're just looking to buy a passive HDMI cable , then your realistic maximum range is around 25ft. Cable Matters sells a wide variety of options in that category.
Whichever one you opt for though, 25ft is about the maximum length you can use without seeing a degradation in signal quality due to attenuation.
Although passive HDMI cables can support distances more than twice that in theory, the environment would need to be practically perfect to not experience severe negative consequences of such a long cable without some sort of active power to counteract the signal degradation.
If you're looking to hook up ceiling-mounted projectors or building a home movie theatre with the media stored far from the eventual display, you'll need a relatively lengthy and hefty HDMI cable for the job. That's where you'll run into problems with standard, low-cost HDMI cables. Instead, you want to use something like the active fiber optic HDMI cable.
It supports HDMI 2. These cables are light and flexible, making them a great choice for getting to hard to reach places.
