HDMI (for "High-Definition Multimedia Interface") is an audio / video standard that allows audio and digital images to be exchanged between various devices. This is what explains its current success. With an HDMI cable, you can transfer data from any compatible device (computer, console, digital player, etc.) to your television. Even if your device does not have an HDMI port, by installing an adapter, you could set up an HDMI type connection.
Method 1 of 2: Make a direct connection to the HDMI ports
Step 1. Have the correct HDMI cable
If your device has an HDMI port, all you need to do is have an HDMI cable. Of course, you will only take a cable of this type if it meets your needs.
- Today's televisions all have standard HDMI ports. This is the reason why one end of the cable must be equipped with an HDMI socket, also standard.
- Your device (computer, console, etc.) must have a standard, mini or micro HDMI port. See which of the three HDMI ports is on your device and make sure the other end of the cable fits one of those outputs.
- Make sure the HDMI cable is long enough. It should be slightly longer than the distance between your device and your TV.
Step 2. Connect the cable to your device
Connect the correct end of the HDMI cable to the corresponding HDMI port on the device.
- Your device should be on and ready to use.
- The HDMI jack must fit into the port in some sense. You should never use force to introduce the plug. You will damage the cord or your device.
Step 3. Connect the other end to the TV
Insert the other end of the cable into one of the free HDMI ports on the TV, the latter being located at the back of the screen.
- The TV must be turned on.
- If your TV has more than one HDMI port, do not plug the cable into any of them. It must be connected to one of the two ports labeled HDMI-1 or HDMI-2.
Step 4. Change the source on your TV
Using the tuning buttons on the TV or more likely on the remote, switch your TV to the appropriate port.
Usually there is an AV button (extension) or button (remote control) that allows you to change the source of the TV. On the screen, scroll through the menu until you find the connection port (HDMI-1 or HDMI-2)
Step 5. Change some video settings of the device
It is not systematic. Most of the time, the device automatically locks itself as soon as it finds the HDMI connection. If the TV screen remains blank, you may need to make some settings on the device.
- To configure a Windows PC:
- open the control panel and in the section Appearance and Personalization, select Change screen resolution;
- click on the icon of the second screen and check the setting Extend the desktop to this monitor. When it appears, click on the Apply button;
- click on the drop-down menu Resolution of the second display. Find the resolution that you think best suits your TV. The resolution should not be less than 1280 x 720 pixels.
- To set up a Mac:
- open system preferences in the menu Apple, then click Monitors;
- in the dialog box, click on the tab Disposition and check the Video mirroring box.
Step 6. Modify the audio settings of the device
Here again, this is not systematic. If you have had to make adjustments for the video input, you will also have to make adjustments for the audio input, otherwise the sound will not come out through your television, but through your device.
- If you have a Windows PC:
- open the control panel, then click His;
- on the Playback tab, right-click on the white space, then from the drop-down menu, choose Show disabled devices;
- select your TV speakers from the list.
- If you have a Mac:
- open system preferences in the menu Apple, then click His;
- under the tab Exit, locate the Type column in the frame, then locate the word HDMI. Select it and validate.
Step 7. Look at your TV screen
If everything has been done right, through your HDMI cable, your device should send crisp picture and sound to your TV.

Method 2 of 2: Make an indirect connection to the HDMI ports
Step 1. Obtain the correct adapter
If your device is not equipped with an HDMI port, you will have to resort to what is called an "adapter". The type of the latter will depend on the output you have on your device.
- If you have a DVI output, which is best for an HDMI connection, you will logically need to get a DVI-to-HDMI adapter.
- If your device does not have a DVI port, it must have at least one USB port or one standard VGA port. Adapters exist for each of these outputs.
- Many Macs have a Mini DisplayPort or Thunderbolt port. The adapters that allow the connection of an HDMI cable with this type of port are the best in Apple technology.
Step 2. Choose the correct HDMI cable
The HDMI cable you are going to take should be able to plug into the HDMI ports of the TV and the adapter.
- All televisions today have standard HDMI ports. This is why one end of your cable must have a standard HDMI socket. As for adapters, the most common also have a standard HDMI port, although some are equipped with mini ports or HDMI micro ports. Of course, the other end of the HDMI cable should be able to plug into the adapter port.
- The HDMI cable must be able to go from your device to the TV. Take a slightly longer cable to avoid too much tension on the cable itself, but also on the connections.
Step 3. Connect the cable to your TV and to the adapter
Plug the standard plug into the HDMI port on the back or side of your TV. Connect the other end of the HDMI cable to the HDMI port on the adapter.
- The television and the device must be switched on before connection.
- Never use force when making connections of this type! It is impossible to go wrong in the connections. So if you can't do it, you don't have the right cable.
- Choose one of the HDMI ports on your TV. They are usually named HDMI-1, HDMI-2, etc.
Step 4. Plug the adapter into your device
Enter the adapter plug into the correct port on your device.
- With a DVI, USB or Thunderbolt adapter, just plug it into one of these ports.
- If you have a VGA port adapter, simply match the colors of the plugs on the adapter with those of the ports, audio and video, on your computer.
Step 5. Make a separate audio connection
With some adapters, you can only stream video from the device to the TV. In this case, you need another cable to transfer the sound, an audio cable.
- This situation is rather rare these days, but it does happen if you are using a DVI-to-HDMI adapter or, even older, a USB-to-HDMI adapter.
- If your device and your TV each have the correct ports, you can connect them directly with the stereo cord of your choice.
- Otherwise, you can very well, using an audio cable, switch the sound from your device, not to the TV, but to external speakers. This is often the case when you want better sound.
Step 6. Change the source of the TV
Using the adjustment buttons on the TV or more likely on the remote, switch your TV to the HDMI port you have chosen.
- Usually there is an AV button (extension) or button (remote control) that allows you to change the source of the TV.
- Navigate through the different input options until you find the selected HDMI port. The HDMI source that appears has the same name as the HDMI port (HDMI-1, HDMI-2, etc.).
Step 7. Optionally configure your device
In most cases, the device automatically shifts, both in audio and video, as soon as it finds the HDMI connection to your TV. If the TV screen remains blank, you need to configure your device manually.
- Here is how to do it if you have a PC.
- Open the control panel, then choose Change the screen resolution. Click on the second monitor icon and check the Extend desktop onto this monitor setting. A button To apply appears, click on it to send the video to the TV.
- Go back to the control panel and choose His. On the Playback tab, right-click the white space, and then from the drop-down menu, choose Show disabled devices. Then choose your audio connection to send the sound to your television.
- Here's what to do if you have a Mac.
- Open System Preferences, then click Monitors. In the dialog box, click on the Layout tab and check the Video mirroring box. When you validate this change, the images will be sent to your computer.
- Return to the general preferences menu and click on His. On the Output tab, locate the port concerned in the Type column and select it. When you validate this change, the sound will be sent to your computer.
Step 8. Look at your TV screen
If everything has been done right, your device should send crisp picture and sound to your TV.

- You don't have to buy an expensive HDMI cable. In the matter, either the cable works or it does not. Second, the differences in signal quality between an inexpensive cable and an expensive cable are negligible.
- Regarding the ratio of cable length to picture quality, if you need to send 1080p signal over 7.5m or 1080i signal over 15m, you may need to '' use an HDMI repeater or an active cable (signal booster). These two solutions require a separate power supply.
