How To Check Does My Laptop Have HDMI Input? – HDMI Inputs Demystified

laptop HDMI input

HDMI is an abbreviation for High Definition Multimedia Interface. HDMI deals with High Definition (HD) signals, which are used to transmit high-resolution audio and video content over a single cable.

They are exclusive Audio/Video Interface and, unlike previous systems, do not require an external input audio device and cable. It is now one of the most widely used connectivity standards and can be found in TVs, monitors, laptops, and projectors. They are bi-directional in nature, which means that you can connect either end to an HDMI input or output connection.

If you’re unsure whether your laptop has HDMI input, don’t worry – you’re not alone. Many people are unsure of what type of input their laptop has, and HDMI is just one of many.

To find out if your laptop has HDMI input, look for the port on the side or back of your laptop. You have HDMI input if you see a small, rectangular port with either 19 or 29 pins.

The HDMI port in a laptop or on any device can be challenging to determine: the input or output. You can find out by reading the product manual or visiting the manufacturer’s website. Or, you can use the HDMI port to determine which is the input or output. HDMI input is a type of input that allows you to connect an HDMI device to your monitor or TV. This connection lets you share video and audio signals between the device and your TV.

HDMI input is important because it lets you use your laptop as a display device for watching videos and playing music.

HDMI Design

An HDMI connector may handle input and output, according to one theory put forth by online users.

The port we use is irrelevant based on the intended use. Whether to use the laptop as an output or an input device is up to us. Yet HDMI ports don’t operate that that. As we saw earlier, HDMI ports on the output device encode the digital signals to be carried over the twisted pair wires, and the ports on the input device decode them to be fed into the device.

They cannot perform the opposite of what they are programmed and designed to accomplish. If you want HDMI inputs and outputs, you need to have different ports since their designs are different. Several gadgets that can act as input and output have HDMI IN and OUT markings. Your laptop’s HDMI input port needs to be marked as such if it has one.

Also, some users advise utilizing a specific converter to convert the HDMI output connector on your laptop into an input port. There are no such adaptors available, and you cannot convert a port intended for signal transmission into a port for signal reception.

What Is HDMI, And How Does It Work?

HDMI is a digital interface for transmitting audio and video data. It is a small, round connector typically used on HDTVs, laptops, and other devices supporting high-definition video. HDMI uses a single cable to connect a device to a display, which makes it a convenient option for many users.

What Is HDMI Input On Laptops Used For?

HDMI input on laptops is used to connect the laptop to an external device, such as a projector, TV, or monitor.

It allows you to display what is on your laptop screen on a larger screen. HDMI input is also connected to other devices, such as a DVD player or game console.

What Does An HDMI Port Look Like?

HDMI connectors come in different sizes, with full-size HDMI slightly larger than standard USB. They’re characteristically trapezium-shaped, with opposing faces/slot sides of unequal length. Full-size HDMI connectors are the most common type, and they’re typically used with larger devices like TVs and computer monitors.

Does An HDMI Input Look The Same As An HDMI Output?

No, they don’t. An HDMI input connects an external device to your TV, while an HDMI output sends the TV’s image to another display.

Why Don’t Laptops Have HDMI Input?

HDMI ports are found on televisions, computer monitors, and some gaming consoles, but not laptops. It is because laptops are not typically used as a display for other devices.

Instead, they are the primary device that displays content. HDMI ports on laptops would be an unnecessary feature because there would be no need to connect the laptop to another display.

There are a few possible reasons:

  1. Laptops are portable, and adding an HDMI input would make them bulkier and more difficult to carry around.
  2. HDMI input requires additional hardware, which would add to the cost of laptops.
  3. Most people who want to use their laptop with an external display already have a device with HDMI output, such as a Blu-ray player or game console.

What is HDCP:

How Does HDCP Work

High-bandwidth Digital Content Protection (HDCP) is a data link protection mechanism commonly used by display devices to prevent the copying digital audio and video content.

HDCP operates by encrypting the data link between a content source and content sink (e.g., between a Blu-ray player and television).

The Difference Between Them

HDMI 2.0 and HDCP 2.2 are digital copy protection standards for 4K video. The big difference is that HDMI 2.0 is backward-compatible with previous one versions, while HDCP 2.2 is not backward-compatible regarding the 4K video.

That means you can connect older sources, like a regular Blu-ray player or cable box, to a new 4K TV and enjoy an HD picture.


How To Display HDMI Input On A Laptop?

 There are a few things you need to do:

  1. You must ensure your laptop has an HDMI port. If it does not, you will need to purchase an HDMI adapter.
  2. You need to connect your HDMI cable to your laptop and the device you want to display the input.
  3. You must configure your laptop’s display settings to show the HDMI input.

What Is The Difference Between HDMI Input And Output?

The main difference between HDMI input and output is the direction of the signal flow.

HDMI output refers to the connection that sends the video and audio signals from the source device, such as a computer or gaming console, to the display device, such as a TV or monitor.

HDMI output is a standard feature on most devices, including laptops, desktop computers, gaming consoles, and Blu-ray players.

Can you convert HDMI Output to Input?

Yes! There are a few different ways that you can do this, depending on what you need it for. If you want to use your TV’s HDMI output as a second input, you can use an HDMI to DVI adapter.

You can use an HDMI splitter if you need to connect your HDMI Output to a different device with an HDMI input.

Are there any gaming laptops that have an HDMI-In?

Yes, there are gaming laptops that come with an HDMI-In. It is an excellent feature for those who want to connect their laptop to their TV.

Some gaming laptops that have HDMI-In ports include the Alienware 18, MSI GT72 Dominator Pro, and Acer Predator 17X. These laptops typically have high-end specifications, including powerful processors and graphics cards, and are designed for gaming and multimedia use.

Can I Use the Laptop as A Monitor?

In some cases, it is possible to use a laptop as a monitor for another device, such as a gaming console or a desktop computer. However, the ability to use a laptop as a monitor depends on several factors, including the laptop’s hardware and software capabilities and the device’s output capabilities.

One way to use a laptop as a monitor is to connect the other device to the laptop using an appropriate cable, such as an HDMI or VGA cable.

The laptop must have an input port for the chosen cable type, and the device must have an output port that supports the chosen cable type.

Once the cable is connected, the laptop should be set to “input” mode to display the device’s output.

How Do I Connect HDMI Video to Windows?

To connect an HDMI video device to a Windows computer, you can follow these steps:

  • Ensure that both the HDMI device and the Windows computer are turned off.
  • Connect one end of the HDMI cable to the HDMI output port on the video device and the other end to the HDMI input port on the Windows computer.
  • Turn on the HDMI device and Windows computer.
  • The Windows computer should automatically detect the HDMI device and display its output on the computer screen. If the output is not automatically displayed, you may need to change the display settings on your computer to extend or duplicate the display to the HDMI device.
  • To change display settings, right-click on the desktop and select “Display settings” from the drop-down menu.
  • Under “Multiple displays,” select “Extend desktop” or “Duplicate desktop” to display the HDMI output on the computer screen.
  • You may need to adjust the resolution and orientation settings to optimize the display on the computer screen.


Determining if your laptop has HDMI input is an important step in connecting external devices and displays. By checking the laptop’s ports, manual, specifications, and labels, and using diagnostic tools, you can easily determine if your laptop has HDMI input.

If your laptop doesn’t have HDMI input, there are still options available, but it’s important to check for compatibility and performance before using alternative connection methods.
