Although computer screens can reach large sizes, up to 27 inches diagonally, or almost 70 centimetres, they don’t match the dimensions of TVs that can exceed 2 metres. The quality of these screens is good, but there’s nothing like a big screen to watch your favourite movies or TV shows or enjoy your games.

The way you can connect your computer to your TV depends on the connections available on your computer and the ones offered by your TV. Here’s how to find the easiest solution.

1. Check your computer’s connections

The first step is to look at your computer’s video output connections.

    – Virtually all desktop, so-called fixed computers today have at least one of the following two outputs, sometimes both at the same time:

        ◦ The first is the VGA output. It is usually blue and consists of 15 holes. This connector can also be called RGB or HD-15 connector.

        ◦ The second is the DVI-D female output. It is white and consists of 24 holes plus a horizontal coding. It is newer than the VGA connector and offers a better signal quality.

    – On more recent desktop PCs, other connectors are available. Thus, you will find more and more HDMI connectivity.

    – For laptops, the presence of external video connectors is not guaranteed. Some of them have the same connectors as desktop PCs and therefore do not pose any problem. On older models of laptops, you can find the S-Video connection, inherited from the world of video.

    – On the other hand, some laptops, especially Apple models, have proprietary connectors such as the Apple Thunderbolt connector. Here, You will need specific cables to connect your computer to your TV.

2. Check the TV set’s connectors

Connect Your PC to Your TV

After you have identified the video output connectors available on your computer, you need to take a closer look at your computer to check the input connectors:

    – The most common video input is indeed the SCART. Even if it is disappearing, many TV sets are still equipped.

    – The RCA video connector, also called Cinch, is inherited from the video world. It comes in the form of a cable with a yellow plug. It can be associated with two other plugs, white and red, for the sound.

    – The Composite Video input resembles, by its connectors, the RCA video input. It can also be called YUV and be associated with the red and white RCA connectors for sound. However, all three connectors are needed to bring in the video signal here. They are red, blue and green.

    – In a more traditional way, connectors identical to those of computers are found on your television. Thus, one or more HDMI sockets and a VGA input are often available.

3. Use cables and adapters

Connect Your PC to Your TV

Now that you have identified your computer’s outgoing connections and the incoming connections of your TV, you can determine how to connect the two.

If your computer and TV have the same connections, this is ideal. You will need a single cable to connect them. This is often the case with VGA and HDMI connections.

Otherwise, You will need a special cable or adapter. The most common adapters are:

    – VGA to HDMI;

    – or DVI to HDMI because HDMI is a widespread connector on recent TVs.

If your TV set is old and has only a SCART socket, you will also need an adapter. There are adapters for RCA, S-video and even DVI connections.

Note: when using cables and adapters, please note that the length of the cable can influence the quality of the transmitted image and that there is a greater chance of poor quality with an adapter. Also, the build quality of the cable or adapter is an important factor in getting good quality. If you can use only a cable and not an adapter, do so.

4. Choose the right channel on the TV

To see what your computer is showing on your TV, you need to choose the correct video input channel, much like you choose a channel. Your remote control has either an AV button or a Source button, or an equivalent button (check your TV manual).

Press this button once or several times to select the correct input channel. It is best to do this before you turn on your computer because some computers detect when they are turned on whether the screen is off or on.

Google offers one final solution to connect your PC to your TV. 5 Another solution: connect your TV via WiFi with Chromecast

through its Chromecast system. The Chromecast comes in the form of a dongle that connects to an HDMI port on your TV and via WiFi to your computer.

To stream the image from your computer, you need to use the Google Chrome browser and the Cast extension for this browser. You will then be able to “cast”, i.e., broadcast, a browser’s tab, and its content on your TV.

Note: if you have the mini 4K box and it is connected to your TV, you can use the Chromecast system without buying and connecting the Google HDMI key. However, you still need to use the Google Chrome browser and the Cast extension.

Different types of computer mouse

Computer mouse: wireless or wired

 

It is possible to adapt the pointing of the mouse buttons depending on whether you are right or left-handed.

A laptop or desktop computer has several peripherals:

  • The computer mouse
  • The computer screen
  • The PC camera
  • The printer
  • The USB key
  • The external hard drive
  • The computer keyboard

Computer mouse: an intuitive operation

The mouse is, like the keyboard, a peripheral that allows you to send commands to the computer.

It allows you to move the cursor on the screen and click on an element to act.

The mouse generally consists of two buttons and a scroll wheel:

  • left button (central button),
  • scroll wheel,
  • right button (secondary button).

But there are also mice with three buttons. Apple even offers a mouse with four buttons.

For each main action, each button has a role:

click press on the main button; this allows you to select an item or open a menu;

double click: double press on the main button to open items;

right-click: to open a selection list;

scroll: roll the wheel; it allows you to scroll a list or a page;

middle-click on the wheel: open a link in a new tab of your browser.

Good to know: Some mice also have additional buttons for navigation, acceleration, games…

Different types of computer mouse

There are different types of mouse:

Mechanical mouse: mouse that works with a ball.

The ball transmits the movements of the mouse to the computer.

This type of mouse is less and less common.

This type of mouse will often need to be cleaned to remove the dust caught in the ball.

Optical mouse: the mouse movements are analyzed by an LED.

Laser mouse: mouse movements are transmitted by a laser.

Computer mouse: wireless or wired

As with keyboards, there are wired and wireless mice.

For wired mice, two types of connectors plug into the motherboard:

computer mouse

  • USB,
  • PS2.

There are adapters from a PS2 port to a USB mouse and vice versa.

Wireless mice work in:

computer mouse

  • Bluetooth,
  • Infrared,
  • WiFi.

Bluetooth mice tend to be the most convenient and reliable.

Good to know: Some wireless mice have a charging cradle, which avoids the problem of dead batteries.

Computer mouse performance criteria
This table allows you to compare the performance of a mouse-based on different criteria:

Criteria for choosing a computer

Explanation

Size

Unless you want to use your mouse with a laptop, it’s best to choose a full-size mouse to provide a better grip.

_

Weight

– The weight varies from one mouse to another.
– For intensive use, it is better to choose a light mouse, between 100 and 130 grams, to avoid straining the wrist.

A mouse with wires will be lighter than a wireless mouse since the weight of the batteries increases the weight of the mouse.

Accuracy

– Not all mice are equally accurate.
– To avoid wasting time clicking on the wrong folders or having selection problems, you should get a mouse with reasonable accuracy.

– In general, wired mice are more accurate than wireless mice.
– Laser mice will also be more accurate than optical LED mice and even more so than mechanical mice.

Comfort, ergonomics

– Not all mice have the same shape, so some mice have optimized ergonomics for comfort and a good grip
– You should test several mice to find the shape that best fits your hand.

_

Solidity

– Some inexpensive mice have good ergonomics and precision but need to be replaced quickly.
– For just a few dollars more, it is better to buy a mouse with a longer life span.

_

Design

– Mouse design has evolved, and there are now more and more different designs.
– You can choose the design you like the most while ensuring that it provides good ergonomics.
