HDMI cable connection
High Definition Multimedia Interface translates to High Definition Multimedia Interface. It appeared in 2002. The first version was capable of transmitting a signal at a speed of 4.9 Gbps, digital video with a resolution of 1080 and eight-channel audio 192 kHz / 24 bit.
The development of HDMI technology has led to the emergence of the 2.0 connector. in 2013. The data transfer rate has increased to 18Gbps, can transmit Full HD 3D video with a resolution of 3840 × 2160. The number of sound channels has been increased to 32 for natural sound. Now you can transfer pictures with a ratio of 21: 9.
To connect a computer or laptop to a TV, two types of such a cable are sold:
- HDMI STANDARD;
- HDMI HIGH SPEED.
The standard is a regular version 2.0 cable, and HIGH SPEED is a “tuning” version of regular HDMI, in fact a common marketing gimmick.
Cables differ in the type of connectors. There are four of them:
- A has 19 pins. They are equipped with televisions and most computers and laptops.
- B, 29 pins. Almost never found or used.
- C or mini-HDMI. Reduced version A. Widespread and used in players, smartphones, netbooks, laptops, PCs and cameras.
- D or micro-HDMI. Even smaller version A. Fits into cameras, portable devices, smartphones and tablets.
HDMI to mini-HDMI adapter. HDMI to micro-HDMI adapter.
ATTENTION! Before buying a cable, you should carefully consider the inscription next to or the computer connector itself. TVs use regular type A connectors, laptops and PCs use regular or mini connectors.
Cables are sold in lengths from 30 cm to 15 meters. When choosing, you should pay attention not only to the type of connectors, but also to the thickness. The longer, the thicker it should be. The characteristic barrels must be present. They protect against interference and electrical interference. Lack of such protection can lead to equipment failure.
Having chosen the cable, we connect it to both devices. The TV may have several of the same connectors. Remember the number to which the cable is connected so as not to get confused when setting up.
- Almost all new TVs and computers are equipped with such connectors;
- The connection is very simple;
- Availability and low cost of the cable;
- Video and audio data is transmitted over one cable;
- A high resolution.
Wireless connection via Wi-Fi or Ethernet
For data exchange, it is necessary that the devices be equipped with a Wi-Fi module or support this technology.
For laptops, this will not be a problem; with rare exceptions, they have built-in Wi-Fi, like Smart-TV. TVs that do not support the Smart function and regular desktops will need to connect an external or built-in adapter.
ATTENTION! for TV it is better to purchase an adapter of the same brand.
The transfer of image and sound from a computer to a TV is carried out in two ways:
- Via a local Wi-Fi network with a router or cable;
- Intel Wireless Display (WiDi) or Wi-Fi Miracast.
A data transmission standard developed back in 1987. Fifteen pins have this connector and provide analog video signal transmission to a monitor or TV with a resolution of 1280×1024 pixels.
Only the image can be transmitted with the VGA cable. Separate wires must be used to transmit audio signals.
It’s easy to connect. It is not a problem to find a cable 10 meters long. You can also connect from a computer via an HDMI. VGA adapter with RCA “tulip”, then sound will be played through the TV speakers.
- Sufficiently high resolution of the video signal;
- It’s easy to connect;
- There is a nest even on laptops.
- Sound is transmitted over a separate wire;
- Not all TVs have a VGA jack.
LAN connection (or DLNA)
It is carried out by combining devices through a router. The TV must have a DLNA technology support function, this characteristic is reflected in the manual or description.
It will be necessary to create folders with movies, audio tracks, photos on the PC. LAN capabilities allow you to view the contents of folders on the TV monitor by controlling the remote.
- Configure the router to automatically distribute network settings with a password.
- Connect TV to local network. Find the Network Settings tab in the menu and activate the wireless connection (connection) function. Find your own in the list of found networks, enter the password and connect.
- For easy management of files stored on a PC, you need to download and install an access program on it, or in other words, create a media center. There are many programs, it is very easy to find understandable and convenient.
- That’s all, you can view audio, video and photos.
Using the same DLNA technology, you can connect a computer to a TV using a twisted pair cable. To do this, both devices must have LAN (Ethernet) connectors. A local network created in this way is similar to a wireless.
DVI has been in use since 1999. With its appearance, analog signal transmission was replaced by digital. DVI cable replaced SVGA. A characteristic feature of the connectors is the presence of side screws for fixing.
DVI with mono channel signal transmission provides a resolution of 1600 × 1200 pixels. With two-channel, the resolution increases to 2560 x 1600. This requires a special connecting cable with a large number of pins. Therefore, when choosing a cable, you should pay attention to the correspondence of the cable contacts and jacks. Three-channel data transmission provides up to 3.4 Gbps throughput on each channel.
On TVs, the connector is usually referred to as DVI IN, i.e. the device is working on receiving a signal. Video cards of computers and beeches are labeled. DVI OUT.
If the PDA does not have an outlet for such a cable, then you can use an HDMI. DVI adapter.
REFERENCE. Only the image can be transmitted with DVI. Separate cables must be used for audio signals.
DVI cables can be found up to 5 meters long.
- Easy to connect;
- High video resolution.
- Laptops rarely come with these connectors;
- Extra wire;
- Sound is transmitted over a separate wire.
RCA and S-Video
Good old tulip or RCA connectors are found in almost all TVs and many computers. The video signal plugs are colored yellow, and the audio plugs are white and red.
The clarity of video transmission is not high, but if there is nothing else, then this method can be used.
The tulip is connected to the TV, and to the computer through the S-Video connector. The sound will have to be played on a laptop or output on a separate wire.
- Has only for obsolete devices.
- Poor quality of the transmitted signal;
- A separate wire is required for audio transmission;
- Laptops are not equipped with such slots.
How to connect a cable from a computer or laptop to a TV?
Televisions are getting smarter every year and are already performing many of the tasks common to computers. Monitors of computers and laptops are gradually increasing and becoming more convenient, but still sometimes you want the TV to become smarter, and the computer’s screen has grown. The symbiosis of a large screen and a smart laptop can be achieved by connecting them either by cable or wirelessly.
