How long hdmi cable before quality loss

While HDMI cables are pretty popular these days, their types and lengths are not things people normally know about. In a nutshell, yes, the length of the cable affects the audio and the video quality.

This is mainly because of the fluctuating signals as t he sound and video travel through the HDMI cable. In general, there is no specific length that tells you that the HDMI cable is too long or too short. In fact, manufacturers and sites have different answers on how long an HDMI cable should be.

For the ordinary customer, this is confusing. Sorry to burst their bubble, but HDMI cable quality is not dependent on the brand of the cable. If they have passed the specification requirements, then both will work just fine. If you want to buy the more expensive one, know that this can end up being an excessive buy since you can buy the same quality for a cheaper price. So are cheap HDMI cables better?

A cheaper HDMI cable is only better if and only if it has passed specification requirements. This is what other more expensive brands are taking advantage of. On the other hand, more expensive cables are not entirely bad, especially if they have other features included in the HDMI cable.

Some have more heavy-duty connectors which are really important for durability purposes. 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.

Cable Matters. Hello Nathan, For distances of 50 feet, you'll definitely need an active cable. Please shoot us an email at support cablematters. So i need a HDMI connection for pretty exactly 20m Or shall i use something different? I dont wanna spend too much, so i am not gonna buy a glass fibre or similar, its kind of temporary.

Hey there, A repeater plus two 25 ft. Amit Tyagi. Hi Amit, yes our cables support eARC as well! Would require about 25 meter long single cable run to complete the connection. What should be the cable type, specification etc. Hello Matthew, An active optical cable would be required at that length, though they are typically several hundred dollars. You can simply run a 25m Cat6a cable instead. I've found lots of cables that are capable of 40k60fps , but none that work or Generally, when it comes to HDMI cables, the shorter, the better.

This is to prevent signal degradation which tends to occur around the ft mark. In some cases, a long cable will just be unreliable. An HDMI cable can still work over long distances, but you might run into graphical artefacts, a loss of brightness, input lag, a low refresh rate, and other issues.

When you start encountering those issues, you can bet that the cable is running into issues. While there are many different types of HDMI cables, most of them start to encounter signal degradation around the meter mark 50 feet. Another thing to keep in mind is that sharp bends can degrade the signal further.

Since 4K requires a lot of bandwidth, most cables cannot transfer the resolution over distances of more than three meters. In some cases, the distance will be much shorter, around the one to two-meter mark.

The longer the cable, the lower the resolution. If you want to get the absolute best resolution, make sure the HDMI cable is no longer than necessary. What these devices do is, in simple terms, add more power to the cable, to boost the digital signal. The devices strengthen the HDMI digital signals. What you do is plug the signal booster into a power source, and then plug an HDMI into either end. These signals can boost the usable distance of cables. The effectiveness of the repeaters varies, but it usually falls within 10 to 15 meters.

For example, you can run a meter cable from your computer to repeater, connect another meter cable to that repeater, and finally to a display. This solution works okay for outdoor projectors or digital signage. That creates a lot of cables. I would only recommend this if you already have Cat cables lying around that are not in use. Regular copper HDMI cables have a number of limitations, such as the distance signals can transfer without losing data. The technology is quite different.
