branded cables are a waste of money. Especially if you only need to purchase a short "lace" about a metre and a half long.

The quality of the cable plays a really important role in analogue technology, when the wire can really change the quality of the sound or image. After all, the analogue signal at the input and output can differ significantly and anything can affect this — from poor shielding to an oxidized contact.

In the case of a digital signal, everything is different. The information at the input and output will be the same, unless, of course, the wire is damaged. Thus, the claim that one cable can provide slightly better quality is simply wrong in its essence, since it implies that the information at the input and output will be different, which should not happen at all in the case of a digital signal.

Buy an expensive HDMI cable only if the signal is transmitted over a distance of more than a few metres. But the fact is that for most consumers, a one and a half metre cable is enough, from the signal source to the TV. And in this case, spending several tens of dollars on a cable simply does not make sense. However, even in the case of 10-metre cables, we are not talking about improving the signal at all, but about its high-quality delivery from the source to the receiver.

Of course, you should not save too much either. A good cable should be of high build quality, not "torn in the hands." The author has seen “masterpieces” made in China, in which the shielding braid was made from the thinnest foil taken from food packaging, even logos and inscriptions were preserved on it. Naturally, such purchases should be avoided.

There are also other marketing moves. For example, the label on the packaging may say that this cable is best suited for TVs with a 240 Hz refresh rate. Or specifically for TVs of certain brands. Again, all this is nothing more than a trick designed to extract an extra couple of tens of dollars from the pockets of gullible consumers.
