Connecting a laptop to a TV provides tangible benefits:
– the ability to watch movies on a large screen in good quality;

In general, there is a whole mountain of pluses and it is a sin not to use all the possibilities of modern technology, especially when they would seriously make life easier and brighten up leisure.
In this article we will look at how to connect a laptop to a TV, which connectors are there for this, which of them transmit only video, and which sound …
Stages of connecting a laptop to a TV:
1) Decide on the types of connectors. Your laptop must have at least one of the following connectors: VGA (common) or DVI , S-video, HDMI (new standard).
2) Next, go to the TV, to which we will connect our laptop. The panel with connectors on the TV must have at least one of the outputs listed above (see item 1), or the 'SCART' output.
3) The last step: if you do not have the appropriate cable, you need to purchase one. By the way, you may have to purchase an adapter.
All this in more detail.
This connector is the most advanced to date. In all new technology, it is he who is built in. If your laptop and TV were recently purchased, then 99% that you will have such a connector.
The main advantage of the HDMI connector is its ability to simultaneously transmit both video and audio signals! Moreover, you do not need any other cables and sound and video will be transmitted in high quality. Video resolution can be set up to 1920 × 1080 at 60Hz, audio signal: 24bit / 192kHz.
Needless to say, such a connector will allow you to watch videos even in the newfangled 3D format!
Quite a popular connector for connecting a laptop to a TV, which is able to provide a pretty good picture, up to 1600 × 1200 pixels.
The main disadvantage of this connection: the sound will not be transmitted. And if you plan to watch a movie, then you will need to additionally connect speakers to the laptop, or purchase another audio cable to transfer the audio signal to the TV.
In general, a very popular connector, however, you will not always find it in laptops. More common in conventional computers and televisions.
There are three different variations of DVI: DVI-D, DVI-I, and Dual Link DVI-I.
DVI-D – allows you to transmit only one video signal with a picture resolution of up to 1920 × 1080. By the way, the signal is transmitted digital.
DVI-I – Transmits both digital and analog video signals. Picture resolution as in the previous version.
Dual Link DVI-I – allows you to achieve image resolution up to 2560 × 1600! Recommended for owners of TVs and high-resolution displays.
By the way, there are special adapters that allow you to get a DVI output from a VGA signal from a laptop and easily connect to a modern TV.
The video image is pretty good. Only such a connector is practically not found on laptops: it is a thing of the past. Most likely, it can be useful to you if you want to connect your home PC to the TV, it is still quite common on them.
RCA or 'tulip'
A very common connector on all TV models. Can be found both on old models and new ones. Many set-top boxes were connected to the TV and they are connected via this cable.
On laptops, however, it is very rare: only on older models.
Found on many modern TV models. There is no such output on a laptop, and if you plan to connect a laptop to a TV using this connector, you will need an adapter. Most often on sale you can find adapters of the form: VGA -> SCART. And yet, for a modern TV, it is better to use the HDMI connector, and leave this as a fallback …
Setting up laptop and TV when connected
After the hardware preparations are over: the necessary cord and adapters are purchased, cables are inserted into the connectors, and the laptop and TV are turned on and are waiting for commands. Let's start configuring one and the second devices.
Setting up your TV
In general, nothing complicated is required to be done. You need to go to the TV settings, and turn on the active connector through which the laptop is connected. It's just that in some TV models, it can be turned off, or not automatically detected, or something else … You can select the active mode (most often) using the remote control by pressing the 'Input' button.
Go to the setting and screen properties of your OS. If it's Windows 7 – you can just right-click on the desktop and select the screen resolution.
Further, if a TV (or any other monitor or screen) is found and defined, you will be offered several actions to choose from.
Duplication means showing on the TV everything that will be shown on the monitor of the laptop itself. Conveniently, when you turn on a movie and do nothing further on your laptop.
Expand screens – an interesting opportunity to watch the desktop on one screen and work while a movie is shown on the second!
