Do laptops have HDMI input ports are everywhere now because of their high-quality signal transmission, and more important, their capacity to transmit video and audio signals. They let you create a home theater system or connect multiple devices, without the need of two cables. It’s the reason HDMI cables have been replaced with VGA as well as RGB cables There’s practically no gadget that doesn’t include the HDMI port.

Laptops are among the many devices that have HDMI ports. This allows users to connect to various devices as well as share audio and video. Although it’s not the most often, you might need to make use of the laptop screen as a second screen to import video or audio. It is possible to wonder whether your laptop is equipped with the HDMI input.

Does My Laptop Have An HDMI Input? (How To Check)

Find out whether your laptop is equipped with the HDMI input by examining the sides of your laptop for ports that are not included. You will find do laptops have HDMI input ports integrated into the panel right next on top of each other. Additionally, the specifications on the laptop’s owner manual and on the website will indicate the presence of an HDMI input port.

The HDMI input isn’t an usual laptop feature because they aren’t used as secondary screens to play videos from different devices. Therefore, they do not incorporate them into their designs since they’re costly and add to the cost of purchasing a laptop. You may also find older laptops, particularly models produced by Alienware that have the HDMI connection port.

HDMI Ports In Laptops

As stated, HDMI ports are found on the majority of display and input devices, as they make the transfer of audio and videos super simple. HDMI can make installation of home theaters simple since it’s a dual-in-one cable that eliminates the requirement to use separate cable connections and cables for video and audio. Laptops aren’t a rare thing.

There’s no modern laptop that doesn’t have an HDMI port as it’s necessary for streaming laptop audio and laptop images to monitors and displays. However they are HDMI ports found on laptops are usually HDMI outputs but not inputs. Here are the most important reasons why you won’t see HDMI ports on laptops.

1. Laptop Design And Purpose

Laptops are intended to be sources which generate video or data and then project the videos and images onto larger screens , such as a television or monitor. It’s not the reverse as laptops aren’t used by users to make use of laptop screens as receiving devices for displaying images generated from other gadgets. In the end, an HDMI output will be sufficient. But that does not mean that you aren’t able to use the HDMI output on your laptop.

The problem is that it’s not essential. If laptop manufacturers decide to add an HDMI input into their laptops, they’d need to go through an expensive and lengthy designing process, adding to the price of laptop. Thus, even if have a laptop that comes with the HDMI connection, the laptop is likely to be more expensive than other models due to its premium feature.

2. HDMI Design

The most popular theory online users have put forward suggests that the HDMI port is able to handle both output and input. Depending on the goal It doesn’t matter what port we choose to use. We can decide whether we want to use laptop as an input device or to be an output tool. But, HDMI ports aren’t working as they should.

As we’ve seen earlier, HDMI ports on the output device encode digital signals that are transmitted through the wires of twisted pair while the ports on the input device translate these signals and feed them to the gadget. They’re wired and designed to perform the job in question and don’t function in the opposite direction. If you’re looking to have HDMI inputs as well as outputs it is necessary to choose different ports as their designs differ.

You will see HDMI in and out labels on numerous devices that act as output and input. If your laptop is equipped with the HDMI input , the port needs to be identified as such. Additionally to this, some people suggest that you convert an laptop’s HDMI output port into an input port with an adaptor that is specifically designed for it. There aren’t such adaptors and it is impossible to modify a port made to transmit signals in order for receiving signals.

What Laptops Have HDMI Input Ports?

As we mentioned it’s possible to get HDMI input ports in laptops however, it’s not common. In the event that the maker decides to include the necessary circuitry for this feature, you will observe the HDMI-in port in the HDMI-out section on the right side of your laptop alongside other ports. You can also look up your laptop’s specifications within the user’s manual , or on the website of the manufacturer and search for HDMI-in ports.

However, a number of Alienware laptops have these ports.

  • m17x R3.
  • m17x R4.
  • m18x R2.

But, these models are outdated and obsolete. It is possible to search for alternative ways to use your laptop to display your work.


The only time you won’t get these labels–even the fact that it’s both output as well as input, is when your device is an HDMI ACR type. Audio Return Channel (ARC) HDMI ports were released with HDMI 1.4 that allows devices to function as an output and input device, transmitting as well as receiving signal. The principal purpose of ARC cables and ports is that they decrease the number of cables needed for connecting two gadgets.

But, as the name implies the ARC cable is typically utilized to transfer the audio signal between devices. As an example, if connecting an audio receiver the sound bar system using through an HDMI cable for example, you will be able to transmit audio and video through the speaker from your receiver.

The TV is able to receive audio from the AVR and transmit audio signals to the same device. In the end there is no need for two cables to send and receiving the audio and video signals for and back to your television. But, it’s not possible to find the ARC HDMI port in a laptop, as it’s used only for audio and there’s no reason to include these ports on laptops.

How To Use Your Laptop As An Input Device?

If you’re looking to use the laptop’s monitor to act as an input device for receiving audio and video from a different device, you cannot make use of an HDMI port. The majority of HDMI ports found on laptops have output and you aren’t able to use them in both ways. But, you may make use of other solutions to receive video and audio signals from your laptop.

Here are the best:

1. Capture Card

The most commonly used method is using a camera even though these are costly, and you can buy an 4K TV for the same cost. But, you can opt to a device such as the capture card rather than the 4K TV in case you’re limited on space or want to record video during game streaming. The capture card can be described as a type of device which connects to the devices USB port.

It transmits signals for video to a PC through the conversion of video signals generated by an HDMI port into information that can be read by a computer. These cards permit you to capture video from an output console or other device and then record it if you would like.

It is also possible to have capture cards in the form of PCIe expansion cards that are used in desktop computers if their motherboards come with an available slot. Connect the capture device directly to your output device using an HDMI cable and connect it to your laptop’s USB port using the USB cable.

The videos recorded by these devices are 4K with huge quantities of data, you require an USB port that is able to transfer information quickly. Therefore, a USB-C or Thunderbolt ports is the most popular alternative to other ports. A popular and well-known cameras is Elgato 4K60S+ which is widely praised for its affordable price and performance when as compared to other cards.

However, if you’d like to purchase a different product ensure that your laptop is compatible with the system requirements. A majority of these cards require a top-of-the-line laptop equipped with powerful graphics in order to produce outstanding outcomes. It is possible to experience slow-moving images if you don’t have a laptop that can meet the requirements of your system.

Thus, you need to consider replacing an old capture card with a quality HDTV with the same price or at a lower cost. If you’re absolutely sure you need an capture card, you don’t have to choose between an internal and external card as your laptop can only take the second. Resolution is a crucial aspect based on the purpose for which you are.

If you’re looking to view videos in high-quality opt for 4K however, if you plan to create and upload videos to the internet then 720P is probably enough. However, choosing 4K resolution is most effective option if you’re looking to remain in the future and aren’t worried about the cost. The ability to support HDR (High Dynamic Range) is a further important feature which makes your camera compatible with top consoles and 4K monitors.

How Does HDMI Work?

HDMI (High-Definition Multimedia Interface) (HDMI) is a kind of signal transmission that is capable of handling high-definition video and audio signals. It operates exactly the same way, just like an electronic visually interface (DVI). The only differentiator is that HDMI also transmits audio signals as well. Before the advent of technology the devices were coaxial cables VGA and radio frequency or Scart connections that were all analog.

The result was that images were of poor aspects ratios (typically 4:3) that led to pictures that were square. Additionally these connections could only transmit audio signals and video signals needed other ports. When HDTV was introduced it was apparent that there was a need for a standard that connects digital devices using high-bandwidth connections.

The TVs feature high-definition images due to the fact that they utilize information in the form of zeros and ones. They also have larger screens that offer greater resolution and higher refresh rates. They require a standard for connection which can support high resolutions. HDMI uses TDMS (transition Minimized Differential Signing) to transmit information.

It’s an excellent method to transfer data since it reduces loss of signal usually that occurs in wired connections. This technology helps reduce signal loss through a series of decoding and decoding steps both at the source and on receiving devices and the receiving devices, respectively. Because data is transmitted in the form of ones as well as zeros shift between them could affect the signal.

Coding signals will keep them from changing electronic data to physical signals. Furthermore wires make sure that the signal doesn’t go down through the transmission of signals through one twisted pair as well as their inverse copies in a different. The receiver device receives the signal and interprets it. If the signal that is the source differs from the reverse at the time it reaches the receiver, this indicates that there is an error that the receiver must make up for.

It’s the reason you get HD audio and video via HDMI. These capabilities have allowed HDMI to work with every modern video format that includes HD, Ultra HD, and even 8K. Similar to audio. HDMI can be used to support dual-channel stereo PCM audio as well as eight-channel digital audio that is uncompressed and everything else between. These formats comprise Dolby Atmos and DTS-HD Master Audio and many more.

HDMI Security

HDMI connection is among the most secure forms of connections to stop the spread of piracy. HDMI cables utilize high-bandwidth Digital Content Protection (HDCP) to block devices from copying or recording data without authorization. The two devices connected to one another as the authorized both the sender and receiver to decode and encode signals. This procedure is known as Handshake. It prevents streaming devices or recording devices from taking the data.
