Immediately, way to connect your computer to your TV, we will introduce. In addition, since smartphones and tablets can now be connected to TVs, we will also introduce how to do that.

Use an HDMI cable

To connect your computer to your TV, you first need an HDMI cable. To take advantage of this method, your computer and TV must have an HDMI terminal.

At least one of the PCs and TVs released in the last few years has an HDMI terminal, so look for a terminal labeled HDMI that looks like a trapezoid.

HDMI cables can be purchased for around 1,000 yen. The price varies depending on the length, but it is easy to buy if you can buy it for 1,000 yen. Since HDMI can handle audio files and image files, it is possible to output sound from a TV.

The sound generated from the browser displayed on the TV screen will not be heard from the personal computer speakers but will be properly output from the TV.

The general way to connect your computer to your TV is with HDMI, so first check if your computer and TV have an HDMI terminal, then purchase an HDMI cable of the required length and connect.

How to output your computer screen to your TV with HDMI

When you connect your computer to your TV, your computer will recognize your TV as a display. However, if you already have a computer display, you will need to set your TV as a sub-display.

This is called multi-monitor or dual display. The following is a summary of the setting method when setting multi-display in Windows 10.

  1. Right-click on the desktop screen to launch the menu
  2. Select’s “Display Settings”
  3. Select “Extend display screen” from “Multiple display settings.”
  4. Select “Keep Changes” in the “Keep Display Settings?” Dialog
  5. Once the settings are reflected, you can set the screen by dragging and dropping from the setting screen.

With the above procedure, you can set up multiple displays.

Starting with Windows 10, setting up multiple displays is fairly easy.

By selecting “Expand the display screen” of the display, the TV is recognized as a display, and it is possible to freely arrange the location of the main display and the sub-display.

You can also connect your smartphone or tablet to your TV!

For use as a multi-display device, such as when a personal computer is connected to a TV, a dedicated dock is often used for each smartphone or tablet.

However, by utilizing Google’s Chromecast or Apple’s Apple TV, it will be possible to display it on the TV of the smartphone screen via Wi-Fi. Not all can be displayed. Only compatible apps such as Youtube, Hulu, and Netflix can be displayed.

Many of the compatible apps are video-on-demand services related to video, and you can display the screen you normally see on your smartphone on the large screen of your TV.

Display method when HDMI connection is made

When you connect your computer to your TV with an HDMI cable, you can choose from the following three screen display methods.

  1. Duplicate
  2. Expansion
  3. Second screen

Make sure to select the appropriate display method according to the intended use.

  1. Duplicate

” Duplicate ” is a method to display the same screen on both a computer and a TV.

It is recommended to use it when you want to watch an image on a TV with a large display while operating it on your computer. When watching “NetFlix” or “Fulu,” it is recommended to select this connection method.

  1. Expansion

” Extension ” is the display method that can take advantage of Levi as a personal computer of dual display. You can handle the screen of your computer and your TV screen as one display, which is recommended when you want to work side-by-side with your computer and TV. If you want to work on a large screen, select “Extend” to display it.

  1. Second screen

” Second screen ” is a method that allows you to turn off the computer screen and display only the TV screen.

If you want to use the work on your computer on a larger screen, you should select “Second screen.”

Connection method when there is no HDMI terminal

Depending on the type of computer and TV, there may be no HDMI terminal. For Macbooks, etc., the existing HDMI terminal has been abolished, and only the USB Type C port has been used, so an adapter or cable to convert to HDMI is required.

Conversion adapters and cables are often sold for around 1,000 to 2,000 yen. If your computer has only next-generation ports such as USB Type C and the TV has an HDMI terminal, buy an adapter or cable to convert it.

Find a VGA or DVI port

If you are using an older type of TV, you may not have an HDMI terminal. There are rare TVs that do not have an HDMI terminal, even if they are cheap.

In that case, look for a VGA or DVI port.

The VGA terminal is often the blue terminal, and the DVI terminal is often the white terminal. If you have either terminal, you can output video and treat the TV as a sub-display, enabling multi-display.

However, at this time, there are cases where the personal computer does not have a VGA terminal or DVI terminal. In that case, you need to purchase another adapter or cable that converts the USB terminal to a VGA terminal or DVI terminal.

The cables and adapters there is also about 1,000 to 2,000 yen.

Items to prepare for connecting to a TV (when connecting with VGA terminal or DVI terminal): How to connect laptop to tv

Since both video and audio can be output from the HDMI terminal, the video and audio that you are watching and listening to can be output as they are with a single cable.

However, the VGA terminal and DVI terminal cannot output audio. It is possible to output sound from the speakers connected to the computer or the speakers built into the computer. Still, if you want to output sound from the monitor connected to the TV, you need to prepare an external speaker.

In that case, connect an external speaker to the speaker terminal or earphone jack on your computer, and the sound will be linked. It is a pain point that you can output video but not audio, so it is also recommended to prepare an adapter that converts the VGA terminal or DVI terminal to the HDMI terminal.

What to do when it does not appear How to connect the laptop to tv

Lastly, I would like to introduce what to do when the image is not reflected on the TV even though the computer and the TV connection are good.

First of all, let’s check if the cable is connected properly and if the settings such as “Expand the display screen” are made properly. Let’s take a closer look at what to do if you still can’t see the video on your TV.

Try turning your monitor or TV off and then on again

First, try turning your monitor or TV off and then on again. Even if you connect the cable, it may take some time before it recognizes as a display, depending on the monitor or TV.

Therefore, please turn off the power once, wait about 10 seconds, and then turn it on again. Then, it may recognize that it connects to a cable and recognize the TV as a display.

Let’s reconnect the cable

One of the possible causes is that the cables are not connected properly. Alternatively, the TV may not recognize that the cable has been connected.

Therefore, when you turn the power off and then on again, as described above, try reconnecting the cable as well. It may recognize by carefully checking the orientation of the terminals and reconnecting them straight.

Also, if you are using a conversion adapter, try reconnecting it as well.

The cable may break: How to connect laptop to tv

If the image is not reflected on the TV, the cable may break. HDMI cables, VGA cables, and DVI cables are relatively thick and sturdy, but they may still break inside. It’s hard to say, but you have the option of buying a new cable.

Summary

By connecting a TV to your computer, you can treat the TV as a sub-display. With more sub-displays, you can do a lot more work.

Nowadays, more work is done to spread files on a computer display than to spread documents on a desk. Therefore, having a sub-display makes your work much more efficient as if your desk were wider. If you want to connect your computer to your TV, please refer to the method introduced here.
