The main advantage of a flat liquid crystal product is a very large and wide screen with an expanded image, which allows you to consider the smallest details. Example, It is more convenient for a professional photographer to view images on a large TV monitor, than on a laptop.

There are various ways to connect a laptop to a TV via a cable, discussed below, but such a connection is always made in three stages.
- We determine the presence of similar connectors in the products - if possible, several options, choose the best cable to connect. Users need to know, that different brands of computers may have completely different types of connectors, example, Asus and Lenovo, but everyone has HDMI.
- We buy the necessary components: cable, cord for audio signal, if necessary, different adapters.
- Once connected, you need to find out in the operating instructions, how to set up tv (learn some nuances of setting up TV from Samsung).
Advice! Before switching the laptop to the TV, you need to check if it has a similar connector - otherwise all efforts will be in vain.
HDMI
In this section we will talk about that, how to connect a laptop to a tv HDMI TV, whose connector is present on any flat screen TV and is available in many brands of mobile products.
This type of experts consider quite simple, the main condition is the presence of a special cable with similar connectors. If you connect a laptop to a TV via HDMI, then you can transmit both audio and video, even with 3D content. The resolution will be the most favorable - 1920x1080 pixels.
HDMI cable is significantly different from others, so it will be easy for a beginner to navigate when buying.
After, how you connected the laptop to the TV with an HDMI cable, you need to make all the settings, to switch to TV that input, which you use, provide output of similar images on the monitor of the mobile product and the TV screen. Many modern flat screen TVs have several ports of this type. Therefore, the menu should select the desired, and establish it as the main source. Setting up a laptop is easy: Menu -> desktop -> screen resolution adjustment section -> a window appears -> choose Display, specify the brand of TV.
Display Port
You can connect a mobile computer to the TV using another original method of signal transmission - DisplayPort or DP. It was developed by engineers, to transfer images from a laptop to a TV screen of various modifications.
The resolution of such an image can be the maximum possible for existing technology 3840x2160 pixels. This type of connection is compatible with HDMI and DVI, therefore, if you have such a port, you only need to buy an adapter (div. Photo).
VGA
You can connect the laptop to the TV via VGA with a similar cable, just need to make sure, what is such a connector on the TV, T. TO. On some modern models it is absent.
Manufacturers label it PC or RGB (PC), call it the same when setting up the video source selection menu in the TV menu. When connected in this way, an image is transmitted to the TV screen, but there will be no sound - this cable is simply not able to transmit it. By the way, such a problem can occur with other switching methods. Why there is no sound with an HDMI connection - it is necessary to understand in more detail. The advantages include the fact, that the connector is on any laptop, even old modifications, It's up to you to decide how to connect your laptop to the TV.
DVI
DVI interface is fully compatible with HDMI and DP, experts share the following basic options:
- D;
- I;
- Dual Link or Dual Channel.
If you have the first, you can only transmit a digital video signal, in the second - digital and analog, and the third is a 3D signal.
The cable has visual differences, and the connection process is identical to VGA. To switch the image on the TV, you need to press the appropriate key on the laptop keyboard, at the same time follow the icon. Different products may have different buttons.
To enable monitor switching, you need to press Fn and the key with the icon - when you press the TV at the same time the image will appear, if you press them again, then it will return to the computer monitor. All other settings of the TV and laptop are made similarly to the above options.
S-Video
Almost all laptops have an S-Video connector, therefore, this method of connection is suitable for most users, but it can't guarantee high quality - watch videos with index HD will be impossible. exept this, this type of connection does not transmit an audio signal - you will need to use a separate cable, the TV must have a similar port or SCART jack.
Wireless
Connect the laptop to the TV via Wi-Fi - the best solution, because there are no restrictions due to the length of the cables (they simply do not exist), the computer can be connected via a router. Of course, to implement this method, the TV must have a Wi-Fi module. The main advantage of this connection of the laptop to the TV without wires - a stable signal at a distance 25 meters, which is more than enough for a city apartment.
Computer specialists assure users, that laptops based on Intel microprocessors have the ability to install wireless video transmission / audio signals via Wi-Di (wireless display). The video signal has an extension 1080 pixels and HD quality, it is freely and losslessly transmitted over Wi-Fi without restrictions. A Wi-Di adapter is connected to the TV via the HDMI connector, and in Toshiba's TV, this technology is built into the factory. To provide a wireless connection to the TV via a USB port, you can connect a special device - a receiver, and the transmitter plugs into a computer's USB port.
The disadvantages of this connection system - the device, transmitting signal, has a small margin of safety, it is recommended to work only no further 10 meters of line of sight, therefore Q-Waves Wireless USB AV is used, when both products are in the same room, example, living room.
Warning! The screen resolution of the products is different, therefore, after connecting, you need to adjust this setting for the TV.
We have given the main connection options, but they apply only to modern technology. You can connect a laptop to an old TV, but is the skin worth it?, given cable prices, adapters, including obsolete plugs, have not been in demand from buyers for a long time.
