This wikiHow teaches you how to connect different types of video devices (computers, cameras, and game consoles) through your TV’s HDMI port. HDMI (High-Definition Multimedia Interface) is a popular standard used to transmit high-quality digital video and audio between devices. Even if the device does not have an HDMI port, you can still make the connection using a cable or adapter (adapter/converter).
Steps
Connecting a standard HDMI device
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/65/Connect-HDMI-to-TV-Step-1.jpg/v4-460px-Connect-HDMI-to-TV- Step-1.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/65/Connect-HDMI-to-TV-Step-1.jpg/v4-728px-Connect- HDMI-to-TV-Step-1.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Locate the available HDMI port on the TV. Most TVs today have at least one standard-size (Type A) HDMI port with a 13.9 mm x 4.45 mm specification. These ports are often labeled as “HDMI”. If there are multiple ports, each port will be numbered (e.g. HDMI 1 , HDMI 2 ).
- Some TVs also have HDMI ports on the front or side.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/a/a7/Connect-HDMI-to-TV-Step-2.jpg/v4-460px-Connect-HDMI-to-TV- Step-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/a/a7/Connect-HDMI-to-TV-Step-2.jpg/v4-728px-Connect- HDMI-to-TV-Step-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Select the appropriate HDMI cable. If the device has an HDMI port the same size as the TV (Type A/13.99 mm x 4.45 mm), you only need a standard HDMI Type A cable with the same 19 pins on either end. However, some devices (usually cameras and portable media players) have smaller HDMI ports, which means we need a different cable:
- Type C/Mini-HDMI: This type of HDMI port is often found on older DSLR cameras and camcorders. The port measures 10.42 mm x 2.42 mm and is much smaller than the Type A port. If your device has it, you’ll need a Mini-HDMI-C to HDMI-A cable.
- Type D/Micro-HDMI: This port is even smaller than Type C, measuring only 6.4 mm x 2.8 mm and commonly found on small recording devices like GoPro or some smartphones. In this case, we need a Micro HDMI-D to HDMI-A cable.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/9/98/Connect-HDMI-to-TV-Step-3.jpg/v4-460px-Connect-HDMI-to-TV- Step-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/9/98/Connect-HDMI-to-TV-Step-3.jpg/v4-728px-Connect- HDMI-to-TV-Step-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Connect one end of the cable to the device. Turn on the device you want to connect to the TV, then gently plug the appropriate end of the cable into the HDMI port on the device.
- We can only plug the end of the HDMI cable into the port in one direction. Never try to plug the end of the cable into the port, as doing so can damage both the cable and the device.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/16/Connect-HDMI-to-TV-Step-4.jpg/v4-460px-Connect-HDMI-to-TV- Step-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/16/Connect-HDMI-to-TV-Step-4.jpg/v4-728px-Connect- HDMI-to-TV-Step-4.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Plug the other end of the cable into the TV. If the TV is off, turn on the TV and plug in the cable properly. If your TV has multiple HDMI ports, you’ll need to write down the number of the HDMI port you’re using.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/70/Connect-HDMI-to-TV-Step-5.jpg/v4-460px-Connect-HDMI-to-TV- Step-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/70/Connect-HDMI-to-TV-Step-5.jpg/v4-728px-Connect- HDMI-to-TV-Step-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Switch to the HDMI source on the TV. Use the SOURCE or INPUT button on the remote control or TV to select the HDMI port. Usually we need to press several times until we reach the correct port number. When you open to the appropriate source, an image of the device will appear on the screen.
- On Windows, press ⊞ Win + P to open the Windows Project panel, then select the option to show the screen on the TV. For example, if you want to project your desktop on your TV, choose Duplicate .
- On Mac, the screen is automatically projected onto the TV. If the size looks unbalanced, you can open Apple menu > System Preferences > Displays > Display and select Default for display . If you want to enter a specific resolution then select Scaled and enter the size. [1] X Research Source

Configure the computer’s sound to play through the TV (optional). If you have connected your computer to the TV and want to make sure that the sound will play through the TV’s speakers, proceed as follows:
- On Mac : Go to Apple menu > System Preferences > Sound > Output and select TV or HDMI output.
- On Windows: Right-click the sound icon in the system tray (next to the clock), select Sound Settings and select your computer’s default audio device with the usual name Speakers (High Definition Audio). ) from the “Choose your output device” menu.
Connect a device without an HDMI port to the TV’s HDMI port
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/4/48/Connect-HDMI-to-TV-Step-7.jpg/v4-460px-Connect-HDMI-to-TV- Step-7.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/4/48/Connect-HDMI-to-TV-Step-7.jpg/v4-728px-Connect- HDMI-to-TV-Step-7.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Identify the HDMI-compatible port on the device. If your TV has an HDMI port, and your game console, computer or other electronic device doesn’t, you can still connect a converter from the given port to the HDMI Type A (standard) connector. You can find HDMI cables/converters for the following port types:
- DisplayPort: This type of port after converting to HDMI can support both high-definition video and digital audio. The label on the port will denote “DP” or “DisplayPort”. If your laptop or tablet uses a DisplayPort port, you’ll need a DisplayPort-to-HDMI-A cable or adapter. [2] X Research Source
- Some devices, including the Microsoft Surface, have Mini DisplayPort ports in place of the standard size. In this case, you will need a Mini-to-HDMI-A DisplayPort cable or converter.
- DVI: The DVI port does not support audio transmission, but you can transfer high-quality video using a DVI-to-HDMI-A cable or converter. Note: DVI ports come in different sizes, so you need to use the right cable. Count the number of pins in the DVI port and compare it to the number of pins on the existing cable and adapter.
- VGA: With the VGA port commonly found on older devices, it will be difficult for you to experience the best picture quality on TV and, of course, no sound. However, you can still connect to the device using a VGA-to-HDMI-A converter/adapter.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/68/Connect-HDMI-to-TV-Step-8.jpg/v4-460px-Connect-HDMI-to-TV- Step-8.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/68/Connect-HDMI-to-TV-Step-8.jpg/v4-728px-Connect- HDMI-to-TV-Step-8.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Select the appropriate cable or adapter.
- Most TVs these days have at least one standard 13.9 mm x 4.45 mm HDMI (Type A) port. You can easily find cables with an HDMI-A connector with the other end being DVI, DisplayPort, or VGA. Then you just need to make sure the non-HDMI plug fits into the port on the device.
- Your other option is to buy a smaller adapter/converter. With the adapter, you need to plug a standard HDMI cable into the HDMI port and a standard DVI, DisplayPort or VGA cable into the other end of the adapter. This means you will need two different cables plugged into one adapter.
- The HDMI cable should be long enough to connect the device to the TV. Choose a cord that is slightly longer than it actually is to minimize strain on the cable and both devices.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/a/a6/Connect-HDMI-to-TV-Step-9.jpg/v4-460px-Connect-HDMI-to-TV- Step-9.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/a/a6/Connect-HDMI-to-TV-Step-9.jpg/v4-728px-Connect- HDMI-to-TV-Step-9.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Plug the HDMI-A end into the port on the TV. Turn on the TV if it is not already on, then connect the cable properly. If your TV has multiple HDMI ports, you’ll need to write down the number of the HDMI port you’re using.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/db/Connect-HDMI-to-TV-Step-10.jpg/v4-460px-Connect-HDMI-to-TV- Step-10.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/db/Connect-HDMI-to-TV-Step-10.jpg/v4-728px-Connect- HDMI-to-TV-Step-10.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Plug the other end of the cable into the device or adapter. If using an HDMI-to- (other standard) cable, plug the appropriate end into that port. If you purchased an adapter, plug the end of the HDMI cable into the HDMI side of the adapter, and then connect the adapter to the device using the corresponding cable (DVI, DisplayPort, or VGA) for the device.
- Do not try to plug the end of the cable into the port. The end of the cable only plugs in one way, and if you’re having trouble, this type of cable may not be suitable.
- If you’re using an adapter for the VGA port, you’ll need to plug in the adapter according to the color corresponding to the video and audio ports on your computer.

Switch to the HDMI source on the TV. First, turn on the device without HDMI port and then use the SOURCE or INPUT button on the TV/remote to select the HDMI port. Usually you need to press a few times for the TV to go to the appropriate port number. When you open the correct HDMI port, the device’s icon will appear on the screen.
- On Windows, press ⊞ Win + P to open the Windows Project panel, then select the option to show the screen on the TV. For example, if you want to project your desktop on your TV, choose Duplicate .
- On Mac, the screen is automatically projected onto the TV. If the size looks unbalanced, you can open Apple menu > System Preferences > Displays > Display and select Default for display . If you want to enter a specific resolution then select Scaled and enter the size. [3] X Research Sources

Connect separate audio if necessary. If you’re not using DisplayPort, you’ll need to use a separate cable to output audio through the TV. [4] X Research Sources
- If both the input device and the TV have the appropriate ports, you can connect the two directly using a separate stereo cable.
- Or you can use an audio cable to redirect audio from the input device to nearby speakers already connected to the TV.
Advice
- If you don’t see a picture on the TV, you need to check the port and connector for dirt or corrosion. If normal cleaning still doesn’t work, try applying more lubricant. In order to limit short circuit caused by excess oil remaining between the contacts, you should only dip a little oil for cleaning.
- Don’t worry about having to buy expensive HDMI cables. Since the signal is digital, there are only cases where it works or not, other than that there is no significant difference in quality between cheap and expensive cables.
- Note: you may need a booster box or active cable if you want to transmit 1080p signals for longer than 7.6 m or 1080i for longer than 14.9 m. Both options above require an extension from a wall outlet. [5] X Research Sources
