Under normal conditions the electrical network at home is required to demonstrate the ground. In the Soviet Union such was not, in some cases, common wire vanishes. Therefore, to transfer the image from the TV to the computer can be dangerous. There is information that the body is at half voltage of the network: it is possible electric shock. If the batteries in the home of cast iron can not touch them at the same time the housing during operation. It is alleged that by being switched off, the device stores a potential danger. Let's see how to connect the TV to the PC.
Standards governing the connection of the TV to the computer
Modern computer TV yourself go online to update the firmware and the software manages the display of the scheduled channel. But still are willing to connect the plasma display to the computer.
Laptop and TV connection
Standards relating to monitors and TVs, is engaged in the organization of VESA. On the official website can be downloaded standards. But not a word is said about the connection rules. We had to hear from owners of television sets, which was a nuisance, because we judge thus:
- Carefully read these instructions before performing the connection to your TV to a computer via hdmi.
- The relevant section is not written that the instrument power is turned off.
- Therefore, in cases of trouble blame the manufacturer.
In fact, the Western companies, in contrast to the Russian officials, law-wrenching right direction, working honestly. Operating manual begins with the general rules. It indicates that the electrical connection is carried out to the standard network. By the standards of foreign countries, the house is connected to ground. But appliances have come from abroad, have to fork ends of the two ground terminals. And the complexity of the local electricians, how to conduct switching.
When it comes to simple appliances can annihilate the appropriate wire, as was the custom in the Soviet Union. Although the ground is fundamentally different. First of all, the point resistance. Earthing better conductive than conventional conductor wire. In the circuit area, usually digged into the ground, the value is a fraction Ohm.
a plurality of ports
Now we shall understand why burn ports when devices are not grounded. Between the hulls creates a potential difference. Current penetrates the insulation and causing damage. As for the practice, the potentials are equalized. Let's see what happens.
Potential equalization housings of electrical appliances
Many are concerned about the issue, why we pay attention to the ground. Repair hdmi port chip is placed four thousand. In some cases, it appears that the attempt to watch television through your computer turns into a breakdown of electronic equipment. In particular, a victim proves that the return performance of the PDP helped physically disconnected burnt chips. Otherwise, you must hike to the master.
Where on the body is taken potential. In most household appliances samples input has a line filter. It is designed so that the phase and neutral wire go through a capacitor to ground. If this place open, then a divider. Its average point goes to the body. At this point, the voltage of 110V is formed Current leaves the phase to neutral. Due to this greatly reduced filtration efficiency.
PC and TV
If two electrical appliance, whose housings are of different potential, unite, then current will flow in a particular direction. The ground he will leave through one of the neutral conductor devices. Trying to connect a TV to a computer via an hdmi on a hot dangerous. If quality grounding can not be done in the off state, connect the two housing ordinary piece of wire. Desirably, copper.
Possibly annihilate the TV and the computer. For this purpose, a surge protector is finished so that the terminals at the ends of wire went to zero. Wall outlet - stationary design. Its phase and neutral wire are on the ground. It is necessary to learn the location. Easier to do this with a special indicator, showing the presence of voltage at the contact with live parts.
Annihilate the land need. This is wrong, but will protect against breakage. Then (if the TV is not included in the reporting line filter) is connected to the housing of both units.
TV interfaces and compatibility
It just looks to have read the previous review about the interfaces for the video stream, are usually used. It provides information that is maintained backward compatibility: buying in a store appropriate adapter, there are chances to watch TV via the second port:
Different cable ports
- Let's start with a VGA graphics port. He rooted in the past, but modern displayport shows the backwards compatibility. If burned analog hdmi, the head of the signal to an old VGA. Interface connectors present in the different interfaces. Adapter solder can almost everyone.
- S-video connector is considered to be a composite channel. The sound is not transmitted. A special circuit for converting the signal for transmission over a coaxial cable. It is simple and includes a single capacitor. S-Video directly with VGA is not compatible.
- DVI digital standard structural part of the rest. The only difference in the transmission rate. The limit for the single-link resolution recognized fullhd. There is information that will interlace unfolding. Having bought the adapter and using the correct settings, the system will achieve performance, when the fault of a single port.
- hdmi inputs In modern multiple TV. Normally, up to four. The standard has gone through several generations, and the need to look at the source and the receiver in the sense of release.
- Displayport is positioned as a versatile device. To include VGA, hdmi and dvi. This information is shown according to the English-language Wikipedia domain. There is no reason to doubt the reliability of the data. More says that only need an adapter to transform signal.
From the above it is clear: if the computer does not see the TV, because of the burned-out port, try to use a different interface. The data transfer speed gradually grew in the improvement technique, however DVI slower than displayport. Therefore, the motion is sure to suffer against the timeline.
In case of a successful replacement, repair is delayed. Or consider the option of selling the forums tainted technology people do not use all the features. But it is recommended for failure to hold back and find out in advance, as a technique to be used to the fault is not surfaced.
How to connect your TV to your PC
The computer finds its own connected TV. In the settings there is an opportunity to include this field in the working screen. For example, extended desktop area. It is not dependent on the interface used. A TV on the computer you want to configure. For this special set source button. In individual cases, it is called differently. With the help of it you need to choose the right source. By pressing through the possible options.
Port Selection depends on the task. If it's just watching the news, you can use any. For those who love high-quality image, it is necessary to switch to digital interfaces. Perhaps the computer via the SCART connection using a special adapter. It is important to understand what kind of interface - analog or digital. Current standards provide the highest quality. As already mentioned, for DVI single-link is fullhd. To watch television, 2K or 4K, or find displayport hdmi.
For DVI single-link speed of 4 Gb / s. 2K and 4K resolution would require, respectively, 1.5 and 6 times greater. These are approximate figures: a lot depends on the frame rate. For example, hdmi second version is suitable to display images at a rate 4K 60 Hz shift. Accordingly, displayport is suitable for any problems that arise.
