Hdmi on pc: How to Connect PC to TV with HDMI: 8 Steps (with Pictures)

How Many HDMI Ports Does a PC Have?

Generally, a computer comes with a host of ports to connect to external devices. A laptop may skip on specific ports, but a full-fledged stationary setup, or a desktop PC, is likely to offer you pretty much all the ports you need to roll and accomplish much more.

Most modern laptops do not come with the ports that were once standard. On the other hand, desktop PCs continue to offer pretty much all ports because there’s still lots of room on them to accommodate them all.

Needless to say, the HDMI port is the most ubiquitous of all the I/O ports. 

That begs the question, how many HDMI ports does a PC (Windows or Mac) have? 

Is an HDMI port a given with desktop and laptop computers? Can a workstation not have an HDMI port at all? And what are your options if your computing device doesn’t have an HDMI port or has just one?

Can a PC Have Multiple HDMI Ports?

Yes, a PC can most certainly have multiple HDMI ports. Since HDMI is a standard digital interface, almost no PC comes without one.

A laptop computer is likely to have just one. However, a desktop PC would have more than a single port since there’s enough space for two or more HDMI ports on it, alongside a host of other connectors.

How Many HDMI Ports Does a PC Have?

As mentioned above, a PC can have anywhere between one or two ports. 

More than two ports is not standard — be it a laptop or desktop computer. And a no-HDMI-port situation is also rare. The number of ports in a PC usually depends on a PC’s form factor and configuration.

A desktop PC usually has more than one. 

The I/O (input-output) section would have at least one HDMI output port alongside other connectors — USB (Type A and/or C), DisplayPort, LAN, audio jacks, etc. There could be one more for the video card. 

A laptop would rarely have more than one, especially the slim and light notebooks, which cut out as many ports as possible and push users to live the dongle life.

If the computer has dedicated graphics, it’s bound to have one HDMI port since it needs to output that raw graphics power to an external device, such as a monitor.

If your PC has no standalone graphics and needs one, use a separate GPU. It would lend you that HDMI port, besides all that raw power.

To get an overview of the ports a typical desktop PC would have, watch this video:

Before buying a GPU, make sure your computer is relatively new or has a capable CPU. If the primary device is more than three to five years old, the GPU will mismatch or not pair well with your archaic device.

Instead, upgrade your system to have an intelligent enough CPU to complement a powerful video card.

What Are the HDMI Ports on the PC For?

An HDMI port helps transmit audio-video signals between devices.

The HDMI ports on your PC help connect it to other devices such as an external monitor or a television. If you’d like to watch web content on a bigger screen, the HDMI port on your PC helps.

Your USB A port will not provide the video input a monitor needs. An audio-video port such as HDMI or DisplayPort is needed for that. 

HDMI is arguably the most mainstream digital interface of the two, since many more devices sport HDMI ports than they do DP. Gaming consoles, for instance, only use HDMI. 

Not to mention, HDMI transmits both audio and video signals, which other video ports such as DVI do not. 

PC HDMI Port Is Output-Only

Kindly note, the HDMI port on your desktop or laptop computer is output-only. The HDMI port on your TV or monitor, on the other hand, takes in digital information.

Your laptop or desktop PC’s HDMI ports cannot work as output jacks, since they don’t have any input circuitry.

Laptops may have an HDMI input port, but those are rare and were found only on laptops launched during the late 2000s, perhaps. Those were the days when laptops were briefcase-like thick and came with a bevy of ports, including a slot to slide in your CDs/DVDs.

The HDMI input port is pretty much non-existent on current laptops, and it looks like it won’t be returning any time soon.

Other modern electronics to sport an HDMI output port are gaming consoles (connect to monitors, projectors, etc.), set-top boxes (connect to TVs), etc.

How Can I Tell How Many HDMI Ports I Have?

If you are new to computers, you may confuse an HDMI port for a USB port, as the two don’t look very different. And because the DisplayPort jack also doesn’t have a very distinct design, you may confuse it for an HDMI port as well.

Compared to the thick and heavy laptops of yore that came with pretty much all the ports you need, the existing slim and light notebooks have limited or only a handful of ports to boot.

Therefore, discerning an HDMI port from others should not be that difficult with them. But some people could still struggle due to the aforementioned similarities.  

Differentiating an HDMI Port From USB and DisplayPort

A full-size HDMI port is marginally bigger than a regular USB port if you look closely. It also has a characteristic trapezium shape, with slot sides or opposing faces of unequal length.

Though there are various HDMI port configurations and sizes, the ones in computers are usually full-sized or mini-HDMI — the latter being a lot more recognizable from your DisplayPort and USB ports since it’s a much smaller size.

To learn more about HDMI port types, the cables that go with them, and how they are different from DisplayPort, watch this video:

Ascertaining the HDMI Version

To help newbies, and for easy identification in general, the term “HDMI” is mentioned near the port on your computer.

If there are multiple HDMI ports and one is newer, the specific versions could also be marked. If the exact type is not mentioned on your PC, you may refer to the user manual or the product’s specifications online.

Since HDMI has not changed in size, shape, or design across all versions, you cannot just look at a port and say which one’s the newest.

Even if that were a possibility, only people who knew more than just a thing or two about HDMI would be able to draw that line.

Suppose you have a basic idea of what the various versions of HDMI bring to the table and your PC’s HDMI capabilities. In that case, you may be able to draw parallels and ascertain the HDMI kind on your device without perusing its manual.

For example, if the HDMI on your computer supports 4K at 60 Hz (maximum), it’s most likely HDMI 2.0 since v1.4 can transmit 4K video at only up to 30 Hz.

How Do I Add an HDMI Port to My PC?

If your computer does not have enough HDMI ports or has none at all, you can either upgrade your setup or use an HDMI splitter — with the latter being the more cost-effective option.

The HDMI adapter plugs into the HDMI port of your computer on one side, and the other side of the dongle would have two or more female ports to allow plugging in an HDMI cable.

Take a look at the following HDMI splitters:

    • Enbuer 1×4 HDMI Splitter

Do not confuse between an HDMI splitter and a switch, as the latter has one output port and multiple input ports.

The Gana HDMI Switch 4K  and Vilcome HDMI Switch , for instance, are HDMI switches even though they have “splitter” in their listing texts.

If your computer has a USB port, you may use a USB-to-HDMI adapter, such as the following:

  • Anker USB C to HDMI Adapter
  • StarTech USB 3.0 to Dual HDMI Adapter
  • TWOPAN USB C to HDMI Multiport Adapter
  • Mokai Start USB 3.0 to HDMI 5-in-1 Hub

The USB-to-HDMI adapters will also help add HDMI capabilities to laptops devoid of DisplayPort and HDMI ports.

If your computer uses only integrated graphics and wants something more powerful and discrete, use an external graphics card. The video card shall also provide you with an HDMI port (as mentioned earlier).

Also, if your device has a VGA port, which transmits analog signals to an external monitor, you may use a VGA-to-HDMI adapter — for instance, the Vention VGA to HDMI Adapter , to make the signal digital.

There is also the option to convert your computer’s VGA port into HDMI. But that’s a long and difficult path that will require enlisting the services of an expert. It is also not recommended with the much easier alternatives mentioned above.


HDMI ports are hard to not find on almost any kind of computer — of course, excluding tablet PCs and smartphones. They use micro-HDMI instead.

And even if your device doesn’t have one, adding HDMI capabilities to the machine is as straightforward as hooking it up with an adapter or dongle-like device.

Besides being “essential”, HDMI ports are also extremely robust and capable of delivering more speed or bandwidth than most other digital interfaces.

That could be one of the reasons Apple decided to bring back the legendary audio-video interface with its 2021 MacBook line-up, which was conspicuously missing on their laptops since 2016.

If you are not planning to buy the latest Apple computers or have a Windows PC (old or new) that doesn’t sport an HDMI port or have enough of them, an HDMI adapter is always there to save your boat.

How to connect PC / laptop to HDMI

Connecting analogue VGA signal from your PC to your digital HDMI display isn’t quite as simple as a one cable connection. However we have some fast and easy solutions to get your PC signal displaying on your HD screen.

Converting PC Signal to HDMI

Though the majority of latest edition PCs and laptops now on the market feature a HDMI output (a relatively recent standard addition), so many legacy PC devices will only feature a VGA video output – or perhaps DVI if you are lucky.

If you are looking to connect your legacy PC or laptop to a modern HD screen – which may only offer HDMI inputs, or if your TV/screen’s VGA connector is already connected to a different video source, or you need to connect your VGA output PC to a HDMI switcher or matrix; then you are going to need to connect your analogue VGA signal to a digital HDMI signal. The solution to this is simple enough – you’re going to need a ‘VGA to HDMI Converter’ also known as ‘PC to HDMI Converter’. There are a huge range of professional and consumer devices available on the market – some which are also capable of converting component or composite analogue signals to a digital HDMI output. With regards to converting VGA, it’s important to remember that a computer’s VGA signal is VIDEO ONLY, the audio signal is on a separate output. HDMI of course is a combined video and audio signal and so a VGA to HDMI converter will allow the VGA and audio signals to be inputted separately, but will then combine the two as a single output from the HDMI.

A professional analogue to digital converter, won’t just combine and convert the signals, but will also provide scaling of the video signal to ensure the best video performance on your HD display. So you need to be looking for a converter which can support up-scaling of your VGA signal to 720p and 1080p resolutions. So whether you’re connecting your PC or laptop to your HD television or integrating PC data into multi-screen, multi-channel High Definition digital signage system – a simple analogue to digital converter makes light work of the job for you.

What is a HDMI?

HDMI stands for High Definition Multimedia Interface and is the most frequently used HD signal for transferring both high definition video and audio over a single cable.

HDMI is used both in the commercial AV sector and is the most used cable in homes connecting devices such as digital TV, DVD player, BluRay player, Xbox, Playstation and AppleTV with the television.

More and more home AV devices are being connected using this simple, effective cable, but now HDMI is also featuring on laptops and PCs and therefore becoming the standard for the corporate and commercial markets – for education, presentation, digital signage and retail display.

How to connect a TV to a computer via HDMI

I decided to prepare a separate article in which I will tell in detail and show with an example how to connect a TV to a regular desktop computer using an HDMI cable. The topic is relevant, and I often get asked about it. In fact, nothing is difficult. But there are some nuances that we will try to understand in the framework of this article.

Almost every, not even the newest TV has at least one HDMI input. And in the computer, on the back panel of the system unit there is an HDMI output. This means that we can easily connect a PC to a TV using a regular HDMI cable, which you can probably buy in every digital equipment store.

Why connect them? Everything is very simple. TV can work as a monitor. That is, you can display an image from a computer on a TV screen. The TV can be used as the main monitor or as a second monitor. This means that the image from the PC will be displayed on the screen of a conventional monitor and TV at the same time. Or just on TV. It already depends on your tasks. It should be noted that HDMI outputs not only the image, but also the sound.

I myself, and other users, most often connect a PC to a TV to watch movies on the big screen, or to play games. You can also connect a gamepad to your computer and play on the big screen. Some people use TVs instead of monitors. They work with documents, surf the Internet, etc. But it seems to me that this is not very convenient. Yes, and the eyes get tired faster. For constant work at the computer, it is better to use a monitor. And connect a TV to watch movies, photos, games, etc.

The connection process will be the same for TVs from different manufacturers: LG, Samsung, Sony, Philips, Panasonic, Ergo, Hitachi, etc. Just like there will be no big differences in Windows settings. Yes, the settings in Windows 10, Windows 8, Windows 7 are slightly different, but not critical. I’ll show you everything.

If you have a laptop, then you can do everything according to this article: how to connect a laptop to a TV via HDMI.

Preparation: check HDMI ports on TV and computer, select cable

First we need to check if our devices have the required ports. We also need an HDMI cable to connect. Let’s look at everything in more detail. If you have everything, then you can go directly to the connection and configuration.

  1. The HDMI input on the TV is usually located on the side, or on the back panel (sometimes here and there). They must be signed and numbered. They look like this (Philips on the left, LG on the right):
    If your TV has at least one such port, then everything will work out.
  2. Next, take a look at the back panel of your computer (I will enter the system unit). There we need to find the HDMI output. HDMI can be either on the motherboard (integrated graphics on newer boards) or on the video card. But, even if you have this port on the motherboard (as I have in the photo below), and there is a separate discrete video card with HDMI output, then the TV needs to be connected to the video card.
    I took a photo of the system unit in a horizontal position. In my case, the TV can be connected to the HDMI output on the video card. If your computer does not have an HDMI output, but has DVI, then you can buy a DVI-HDMI adapter. And if there is only the old VGA, then you can also use a VGA-HDMI adapter, but then the sound will not be output to the TV, since VGA is not a digital output. If you want to connect a TV and a monitor to your computer at the same time, you will need either two HDMI or HDMI and DVI. We will also need the appropriate cables.
  3. HDMI cable must be the length we need. If I’m not mistaken, they are up to 20 meters. If you do not have a separate cable, then you can use the one with which the monitor is connected. If you have it connected via HDMI. I have this cable:
    The most common, inexpensive cable.

If you have ports on both devices and a cable, then you can connect.

Connect TV to computer using HDMI cable

Simply take a cable, plug it into the HDMI output on your computer and the HDMI input on your TV.

Important! Devices need to be connected when they are turned off and the power is off. There is a risk of burning ports. There are such cases.

If you connect the TV as a monitor, that is, the only screen, then the circuit will look something like this:

Also, let’s look at another case when a TV and a monitor are connected at the same time.

TV set as second monitor for PC

The monitor can also be connected via HDMI (as I have in the photo below), via DVI, or even via VGA. As a result, two screens will be connected to the PC.

We figured out the connection. Most likely, in your case there will already be a system unit with a monitor connected to it. And all you need to do is connect a TV to it.

Select HDMI input as signal source in TV settings

Most often, after connecting and turning on devices, there is no image on the TV. There will be an inscription like “No signal”, “No signal source selected” or something like that. On the TV, you need to select the signal source. The port where we connected the cable.

To do this, your TV remote must have a separate “SOURCES”, or “INPUT” button.

After clicking on it, a menu should open in which you can select the signal source. You can see which port on the TV you connected the cable to (each port has its own number). Or just select an active source. The process itself may differ depending on the TV. I have an old LG.

The picture from the computer should appear on the TV. This will be either a copy of what is displayed on the monitor (if any), or a blank desktop (expand).

An article that may come in handy at this stage: why there is no image on the TV from a computer (laptop) via an HDMI cable.

The main thing is that the picture from the computer appeared on the TV screen. Further, in the Windows settings, we can already change the image output mode. There are several of them.

Setting up an HDMI-connected TV in Windows

The screen resolution is adjusted automatically in most cases. So in the Windows settings, we can only change the mode of operation with multiple displays. This is only relevant when a monitor and TV are connected to the PC. If there is only one display, then these settings are not needed.

The easiest way to change the mode in Windows 10, Windows 8 and Windows 7 is the keyboard shortcut Win + P .

After clicking on them, the “Project” menu will appear. In ten it looks like this:

In Windows 7:

Let’s look at each mode in more detail.

  • Computer screen only (turn off the projector) – in this mode, the image will be displayed only on the monitor.
  • Duplicate (duplicate) – will be the same image on the screen of the monitor and TV. There is one caveat in this mode. This is the screen resolution. For example, if you, like in my case, have a monitor resolution of 1920×1080, and a TV of 1366×768, then 1366×768 will be set on the monitor and the picture will not be very good. And if the monitor is 1920×1080 and the TV is also 1920×1080, then the picture will be clear on both screens.
  • Extend – the desktop will be extended to a second screen. In our case, this is a TV.
  • Second screen only (projector only) – this is when the image from the computer will be displayed only on the TV. The monitor is disabled.

In most cases, these settings are sufficient.

Additional screen parameters

To open them, just right-click on an empty area of ​​the desktop. In Windows 10, you need to select “Display Settings”, and in Windows 7 – “Screen Resolution”.

A settings window will open where you can see how many screens are connected to the computer.

You can also define them (by clicking on the “Define” button), change the resolution of each screen and the mode of operation (which I talked about above).

In Windows 7, the settings of a TV connected via HDMI look like this:

We figured out how to set up the image on the computer.

What should I do if the sound from the computer does not go to the TV?

This happens very often. The picture appeared on the TV, but there was no sound. It does not exist at all, or it sounds from the speaker system connected to the computer. If you want the sound to go through the TV, then first check if the sound on the TV is muted or twisted.

Next you need to go to “Playback devices”.

Your TV must be in the device list. You need to right-click on it and set “Use as default”.

If the TV is not in the list, then right-click on an empty area and check the boxes next to two items: “Show disconnected devices” and “Show disconnected devices”.

If this does not work and the TV still has no sound from the PC, then try reinstalling the video card driver. Just download it and run the installation. Let the HDMI cable be connected to the computer at this moment.

How to check these settings in Windows 7, I showed in the article Why there is no sound via HDMI on the TV when connecting a laptop (PC). Be sure to watch it and read the comments. There is a lot of useful information there.

I have never encountered a problem with HDMI audio output. How many connected, everything worked immediately after connection. But there is such a problem.

Connecting a 4k TV to a computer. Ultra HD over HDMI

If you have an Ultra HD TV (aka 4k) and your video card supports this resolution, then there is a chance to get a beautiful and clear image. I checked, everything works. I have a Philips 4K TV. And the computer has a GeForce GTX 750Ti video card that supports resolutions up to 4096×2160.

There are a lot of nuances there. I’m not a gamer, so I’ll try to explain as best I can. The fact is that you can output a 4k image via HDMI, and I did it. But most likely we will get a frame rate of 30 Hz. Which is very little. To get 60 Hz, we need a video card with HDMI 2.0 and the same cable. That is why DVI cables are used to connect to 4k monitors. And I haven’t seen anything on DVI TVs.

I connected everything, started the computer, and saw that the image on the TV was some kind of strange, wrong colors. Maybe it’s just in my case.

Everything is solved very simply. First, I tried to disable UHD (Ultra HD) in the TV settings for the HDMI port to which the PC is connected. The image became normal, but the resolution turned out to be normal, 1920×1080. Therefore, this method is not very suitable for us.

To get a real 4k image with natural colors, you just need to change the screen resolution to the maximum 3840×2160 in the display properties in Windows 10.

The image immediately returned to normal. The scale was automatically set to 300%. Otherwise everything would be very small. It can be changed if necessary. I have not tried to play at this resolution. But I don’t think it’s realistic. Moreover, the video card on my computer is not the newest and not the most powerful.

Waiting for your comments. Ask questions and don’t forget to share your tips. Best wishes!

How to connect a TV to a computer

You might think that connecting a computer to a TV is easy enough: you just need to take an HDMI cable and connect it to the TV, right? But what if your computer doesn’t have an HDMI port? This guide will show you how to connect your Windows 10 PC to your TV.


All modern desktop monitors and TVs are equipped with HDMI ports. Often you can find several ports at once on the back or side panel. Most desktops and many laptops also offer this connection option, making it one of the easiest ways to connect a computer to a TV, especially since both video and audio signals are carried with just one cable.

Two smaller versions of this interface, Mini HDMI and Micro HDMI, are also in use today.

To connect two devices, connect one end of the HDMI male to male cable to the port on the TV and the other end to the computer. Windows 10 recognizes the TV as an external display, which can be verified by right-clicking on the desktop and selecting Display Settings from the pop-up menu.

To display the Windows 10 desktop on your TV, grab the remote and cycle through connections until your PC’s desktop appears.

If the image is distorted, do the following:

Step 1: Right-click on the desktop and select “Display Options” from the pop-up menu.

Step 2: Select your TV from the diagram. The main screen should show “1” and the TV should show “2” or more if more than two displays are connected.

Here you can change the screen resolution, orientation and scaling. You can change the refresh rate if necessary. Here’s how to do it:

Step 1: In the Display panel with your TV selected, scroll down and click on Advanced Display Options.

Step 2: In the next window, click “Display Adapter Properties #” – change the symbol to the assigned TV number.

Step 3: In the pop-up window, click the “List All Modes” button.

Step 4: Select a refresh rate and click OK.

Display Port

Most desktop PCs with dedicated graphics cards have at least one DisplayPort connector, while laptops have fewer. Some laptops have a modified mini-DisplayPort adapter. Unfortunately, TVs don’t usually have DisplayPort connectors – they’re mostly designed for desktop monitors.

In this case, a DisplayPort male to HDMI male cable is required, or you will need an adapter with a DisplayPort male and HDMI jack. In both cases, the computer is connected to the TV in the same way as via HDMI.

Windows 10 should detect the TV as an external display and offer it as extended or duplicated depending on your preference.


Modern computers that do not have an HDMI or DisplayPort connector often have an alternative connection option in the form of USB-C. Keep in mind that not all USB-C ports support video output – it’s just an interface that promises no technology other than USB 3.2 connectivity. Before assuming a USB-C port supports HDMI and DisplayPort output, check your computer’s specifications.

In this case, a plug-in cable is required – a plug with USB-C on one end and HDMI on the other. A USB-C adapter with a USB-C plug and an HDMI socket will also work.

As with a standard HDMI connection, Windows 10 should recognize the TV as an external display.


This port was never really intended for video transmission. Unlike DisplayPort and HDMI, it requires third-party DisplayLink drivers. This method works best with the blue USB ports (USB 3.0, USB 3.1) shown in the image above due to their speed. However, the DisplayLink system requirements also list older non-blue USB 2.0 connections that are slower.

This method requires an adapter or docking station with an HDMI port, as shown in the image above on Mokai Start. Most of them automatically install DisplayLink drivers when they are connected to a computer’s USB-A port. However, these drivers may be out of date, so you must download and install the latest version directly from DisplayLink.

After you connect the adapter or dock and install the driver, Windows 10 should detect the TV. Please be aware that video quality may vary as PC depends on third party software.


VGA, short for Video Graphics Adapter (video adapter), first appeared in 1987 and supports only analog video signals. It cannot boast of versatility, but in some it will be useful. Use a male-to-male cable with VGA on one end and HDMI on the other, or use an adapter with VGA male and HDMI female. Mini-VGA is the smaller variant.

Digital Visual Interface, abbr. DVI – (Digital Video Interface) is a more recent development and is still used in some exceptional cases. There are seven variants of this interface: DVI-I Single Link, DVI-I Dual Link, DVI-A, DVI-D Single Link, DVI-D Dual Link, Mini-DVI, and Micro-DVI. This variety makes it difficult to find the right adapter, so check your PC’s specs to determine the right cable or adapter before you buy.


Make sure your TV is turned on, compatible, and set to receive broadcast from PC. For example, on LG Smart TVs running webOS, owners must first download the Device Connector app and select the PC option, followed by Screen Share and Miracast.

This method will not work if any device is connected to a wired network.
