toroidal ferrite on HDMI cable, what is the purpose?

The ferrite cores are used to block unwanted interference and high frequency noise from affecting your sound on digital cables. Whether you notice a difference or not would depend on many environment variables, but they can't hurt.

to eliminate interference from magnetic waves in the device itself and others around interfering with sound quality. Ferrite is often used to dampen any potential electrical sideways output and usually put in to get UL or CE listing so they can sell.

These are basically inductors used to cancel out radio frequency,which can be noise.

U could use this cord for connecting your laptop to your HDTV if your laptop uses a VGA connection as opposed to an hdmi connection. Your tv will also have to have a VGA connection to. If not I would suggest a VGA to hdmi or an hdmi to hdmi cord. It just depends on which ports your tv and computer have on them already.

Typically, "NO." 1). The field of the permanent magnet is too weak to propagate very far beyond the ferrite attaching surface. What DOES propogate is significantly deminished. 2). The magntic field will "distort" -- to follow the attaching surface. 3). Modern, QUALITY electronics are generally sheilded as a part of their design. You are much MORE vulnerable to the "Vagaries" in your line power -- a result of a decaying, ill-maintained infrastructure.

It converts the component input to an hdmi output. It does not convert the other way.

Hi!Actually, this is not as straightforward as just a cable ... I have an mini HDMI to HDMI that works great to connect my Transformer to several HDMI devices and have watched streamed TV shows in full HiDef with NO hiccups. VGA is another animal (think fish vs mammal ... ;-) ), HDMI is a DIGITAL signal, and VGA is ANOLOG. You can't just "connect" them, you must CONVERT them. Monoprice.com has very good quality cables & convertors at very reasonable prices if you don't find one you like here on Amazon.

It is a large ceramic or ferrite doughnut magnet, not exactly sure. I am sure they are NOT, "rare earth magnets".

that was my situation, which this converter solved perfectly. The yellow cable is likely standard def HVHS, which won't look good at all. don't know what the coax is, an rf signal supposed to go into a tuner?? the hdmi will work with Loftek box. cheers, bill taylor

There is a port on the back of the machine that looks like one, but when I inserted an HDMI cable it didn't seem snug at all. There is a small symbol next to that port that looks like an uppercase "D". I'm not familiar with that symbol. I don't think it is HDMI.

Sorry. We only use them here at the office to back up laptops that have critical information. Haven't used it on a TV.

The BlueRigger High Speed HDMI Cable with Ethernet 6.6 Feet (2-Pack) - Supports 3D and Audio Return [Latest Version] does not have ferrite cores. You can order the individual BlueRigger cables with ferrite cores for a negligible difference. I have never had any issues with noise while using this product.

Iv'e never heard of that happing.Possibley their is a built in on auto switch in the hdmi circut.

Experiment #128 does. You need a radio, it produces static in it as the output. Also, you have to hold the metal right up to the ferrite antenna coil. I haven't built that one yet, just what the manual reads.

The HDMI interface is designed to transfer high quality, digital, multi-channel audio signals along with video at extremely high resolutions and color bit-rates. Being a digital signal with data error correction, it is much less susceptible to low-intensity radio frequency and electromagnetic interference, which would cause snow, ghosting, or other signal distortions in an analog signal.

It was marketed a RCA. From what I understand either works. Its a matter of shielding. I am running this cable next to six other cables without problems.

Sorry, I'm not sure if this cable has ferrite cores. I do not run this cable through the wall. It might be something that you will need to ask the manufacturer.

It allows you to take a standard HDMI and shrink it by one or two sizes. If you have an HDMI cable that has the large flat adapter and want to turn it into the one that fits some smaller laptops, or the one that fits into a camera, this is what you would use.

Not a bad unit Jay. It picks up interference from the internal electronics and power cord. Did you put the ferrite choke on the power cord? I am not too impressed with this unit. For 1000w witch I doubt and the money I would not buy it again. Ken
