An HDMI cable, or High-Definition Multimedia Interface, is designed to carry high-definition multimedia signals. Usually factory high quality cables are used, but sometimes it may be necessary to solder the HDMI connector yourself.
It is necessary
- - cable;
- - Collapsible HDMI plug;
- - soldering iron.
Instructions
Step 1
As a rule, there is usually no need to make an HDMI cable yourself, since you can find quite high-quality samples on the market that cost several dollars. You should be aware that there is no difference in the quality of signal transmission for such a cable and the cost of several hundred dollars. The signal goes in digital form, so it arrives without any distortion. Since a person who has bought high-definition equipment is unlikely to skimp on a cable costing $ 5-10, we can only talk about some kind of special situation. For example, you need a long cord, which you have to solder yourself.
Step 2
When making your own cable, you will need a detachable HDMI plug. Since finding this is problematic, another option is possible - buy a collapsible DVI plug, and take an HDMI adapter to it. You will also need a quality cable - twisted pair of 8th or 7th category.
Step 3
For the exact diagram of DVI and HDMI connectors, look at the sites, links to which are given at the end of the article. To work, you need a miniature soldering iron with a power of up to 25 watts. Since the wires are thin enough, you need to work very carefully. To obtain a high quality connection and prevent short circuits, use heat-shrinkable tubing. Put a short piece of tube on the wire, then solder it. Slide the heat shrink onto the contact and preheat. A connection crimped with an insulating tube will turn out to be very reliable.
Step 4
If you have to solder several pieces of cable, it is important to connect not only the wires, but also the shields. With poor shielding, interference can occur in the transmitted signal, which manifests itself in the form of the appearance on the screen of areas of the image crumbling into squares.
Step 5
Sometimes a situation may arise when the cable cannot be pushed into the hole in the wall, skirting board, furniture, etc. due to the plug. In order not to drill the walls and spoil the furniture, the easiest way is to cut the cable, push it into the hole, and then carefully solder all the wires. This is easier than, for example, removing the plug and then replacing it with a new collapsible one. Before cutting the cable, first cut off the insulation in a small area and mark all the conductors so that later they do not mix up when connecting.
