How to Connect Your Computer to a TV

You might think that connecting a computer to a TV is straightforward: you just grab an HDMI cable and connect the two together, right? But what if a PC does not have an HDMI port? This guide shows how to connect your computer to a TV in several wired and wireless ways on three major PC platforms – Windows 10, MacOS and Chrome OS.

Windows 10

All modern desktop displays and TVs have HDMI ports. In most cases, a panel at the back and / or edge has more than one. Most desktops and a good number of laptops also offer this connection option, making it one of the simplest ways to connect your computer to a TV – especially considering that it only supports video and video with one cable Audio handles both.

The two smaller versions of this interface still used today are Mini HDMI and Micro HDMI.

To wire the two devices, connect one end of the male-to-HD HDMI cable to one port on the TV and the other end to a port on the PC. Windows 10 will then recognize the TV as an external display, which can be verified by right-clicking on the desktop and selecting display settings On the pop-up menu.

Windows 10 right click display settings

To view the Windows 10 desktop on the TV, simply grab the remote and cycle through the connection until the PC’s desktop appears.

If the scene looks bizarre, do the following:

Phase 1: Right-click on the desktop and select display settings On the pop-up menu.

Phase 2: Select TV in the diagram. The primary display should be read as “one” and the TV as “two” – or something higher if more than two displays are connected.

Most desktop PCs with dedicated graphics cards come with at least one DisplayPort connector, although this is less common on laptops. Some have a converted mini-displaypart adapter. Unfortunately, TVs typically do not have DisplayPort connectors – they are reserved for most desktop monitors.

In this case, an HDMI male-to-male cable requires a DisplayPort, or you’ll need an adapter with DisplayPort male end and HDMI port female end. In both cases, the PC connects to the TV in the same way as an HDMI connection.

Windows 10 should recognize the TV as an external display and present it as an expanded or duplicate display depending on your choice.

Modern PCs without HDMI or DisplayPort connectors often have an optional option in the form of USB-C. Keep in mind that not all USB-C ports support video output – this is just an interface that promises no other technology outside of USB 3.2 connectivity. Check the specifications of the PC that supports HDMI and DisplayPort output before handling your USB-C port.

In this case, a male-to-male cable with USB-C at one end and HDMI at the other end is required. A USB-C adapter will also work with a USB-C male end and an HDMI female end.

With a standard HDMI connection, Windows 10 should detect the TV as an external display.

This port was never meant to actually push video. Unlike DisplayPort and HDMI, it requires third-party DisplayLink drivers. This method works best on the blue USB port (USB 3.0, USB 3.1), shown above, due to its speed. However, DisplayLink’s system requirements also list older USB 2.0 non-blue connections, which are slower.

This method requires an adapter or dock with an HDMI port, such as Shown above by Mokey Start. Most automatically install the DisplayLink driver when they connect to the PC’s USB-A port. However, these drivers can be outdated, requiring users to download and install the latest directly from DisplayLink.

With an adapter or dock connected and installed drivers, Windows 10 should search for a TV. Keep in mind that video output performance may vary as the PC relies on third-party software.

Short for video graphics adapter, the VGA first appeared in 1987 and only supports analog video signals. It is far from versatile, but it is usable in some cases. Use a male-to-male cable with VGA on one end and HDMI on the other, or an adapter with VGA male end and HDMI female end. The mini-VGA is a smaller version.

The digital visual interface, or DVI, is the next step and is still in use in some niche cases. There are seven versions of this interface, including DVI-I Single Link, DVI-I Dual Link, DVI-A, DVI-D Single Link, DVI-D Dual Link, Mini-DVI and Micro-DVI. This makes it difficult to purchase the correct adapter, so check your PC’s specifications to determine the correct cable or adapter before making a purchase.


Make sure the TV is compatible, powered on, and the PC is set to receive broadcasts. For example, on LG Smart TVs with webOS, owners must first load the device connector app and select it PC Option, after Screen share And Miracast.

This method will not work at all if the device is on a wired connection.

Phase 1: Press Notification Icon next to System Clock. It launches the action center.

Phase 2: Click Detailed If only four tiles are visible on the floor.

step 3: Press Assignment or Project Tile.

step 4: Choose Connect to a wireless display The roll-out is listed on the menu that appears on the right.

Step 5: Select compatible TV in the list.

Step 6: Follow the instructions on the TV, if any.

Step 7: To end the broadcast, click Disconnect Located on the toolbar shown at the top of the primary screen of the PC.

Note that this toolbar has a gear icon. Gaming, Working and Watching Video: Click this to get three customizations. For the former, it reduces the latency for optimal framerrate. Watching video mode increases latency to reduce buffering, while working mode stays between the two.

To change the broadcast mode, do the following:

Phase 1: Right-click on the desktop and select display settings On the pop-up menu.

Phase 2: The Settings app appears on the screen. Select TV in the diagram.

step 3: Scroll down Multiple displays And click the down arrow to expand the selection.

step 4: Choose a mode: Extend the desktop, duplicate the desktop, display only on TV, or disconnect.

The resolution, scaling, and so on can be changed like any other display.

Mac OS


MacBook USB-C Port

All modern Macs from MacBook Air to Mac Pro rely on USB-C to connect external devices, be it peripherals, external drives or displays. They are all supported by Thunderbolt 3 which promises up to 40Gbps to handle all this data at once.

This method requires an adapter or cable to physically connect the Mac to the TV. However, what the user purchases depends on the actual USB-C port.

The small tree symbol printed next to the port means that it does not support Thunderbolt 3, but it handles DisplayPort video output. Lightning icon means Thunderbolt 3 included. Unfortunately, these symbols do not always appear on the chassis, so check the specifications.

Once a Mac is connected to a TV, MacOS should detect it as an external display. To change the output mode, do the following:

Phase 1: Press system Preferences Icon on the dock. Alternatively, click on Apple Logo Select more in the top left corner system Preferences From the drop-down menu.

Phase 2: Choose Presents In system Preferences Window.

MacOS Access Display Settings

step 3: Press the arrangement Tab.

step 4: To mirror the primary display, click on the box next to Mirror displays. Otherwise, MacOS defaults to extended mode.

MacOS Mirror Display Options

pay attention: Drag the white menu bar icon on the thumbnail of the primary display to the TV screen so that the latter creates your primary display.

Mini displayport

This port is found on older Macs. As shown above, it has a round, box-shaped interface (save for minor angles in the bottom left and right corners). Some only provide DisplayPort output, while others also include older Thunderbolt and Thunderbolt 2 connectivity.

As with USB-C, the printed lightning icon indicates Thunderbolt technology. Without Thunderbolt there is a square icon with a small line on each side.

This method requires a mini display port for HDMI male-to-male cable or an adapter with mini DisplayPort male end and HDMI female end. Once connected to the TV, MacOS will detect it as an external display.

If in doubt, Apple provides a list of ports that are available on past, present, and all Macs.

Apple TV

This is Apple’s approach to mirroring or extending MacOS on a TV over a wireless connection. This requires an Apple TV device that is already connected to a TV’s HDMI port and signed into an Apple account. This is the only solution for those who do not have a TV that basically supports AirPlay 2.

To get started, enable AirPlay on an Apple TV device. Like this:

Apple TV Settings App

Phase 1: Select gray and silver Gear tile On the home screen. This opens the Settings app.

Phase 2: Choose AirPlay and HomeKit On the following screen.

Enable Apple TV AirPlay

step 3: Choose AirPlay If it is not already, turn it on. A prompt asks a name to identify it at the local location and other Apple devices.

step 4: Choose allow access To configure limitations, such as creating passwords and disabling nearby AirPlay access.

Allow Apple TV AirPlay

Now Mac can connect.

Phase 1: Ensure that Mac and TV are connected to the same wireless network.

Phase 2: On a Mac, click the icon next to the Wi-Fi icon on the menu bar. It looks like a screen with an up arrow at the bottom, as shown below.

step 3: Select the target Apple TV device on the drop-down menu.

MacOS AirPlay to Apple TV

step 4: Press Airplay icon To switch between the two modes again: mirror the primary display or use the TV as a desktop extension.

MacOS AirPlay Apple TV Transformation Mode

Step 5: To disconnect, click AirPlay logo Choose more again Stop AirPlay On the drop-down menu.

AirPlay 2 TV

This is another way to wirelessly mirror or extend MacOS to a TV. These TVs have AirPlay 2, which eliminates the need to purchase Apple’s pricey set-top boxes. At the time of writing, they are manufactured only by LG, Samsung, Sony and Vizio.

This method is basically the same, although toggling on Airplay 2 is different on each TV. Take, for example, on Samsung TV Settings> General> Apple AirPlay Settings Path. Once ready, the TV should appear on the Mac’s Airplay menu.

Chrome os

Like Windows 10 and MacOS, various wired options are available to physically connect a Chromebook to a TV. Recent models have HDMI and USB-C connectivity, while other units may offer older VGA and mini DisplayPort connections – even micro HDMI in some cases.

For HDMI, a male-to-male cable or an adapter should suffice. यूएसबी-सी और अन्य सभी कनेक्टर्स के लिए, एक छोर पर एक एचडीएमआई पुरुष कनेक्टर के साथ एक केबल का उपयोग करें या एक छोर पर एचडीएमआई महिला पोर्ट के साथ एक एडाप्टर।

एक बार दोनों कनेक्ट हो जाने के बाद, क्रोम ओएस डेस्कटॉप को कनेक्टेड टीवी पर बढ़ा देना चाहिए। इसके बजाय डेस्कटॉप को मिरर करने के लिए सेटिंग कैसे बदलें:

Phase 1: दबाएं सिस्टम की घड़ी नीचे दाएं कोने में स्थित है।

Phase 2: दबाएं गियर निशान पॉप-अप मेनू पर। यह Chrome OS सेटिंग खोलता है।

step 3: Choose युक्ति बाईं ओर सूचीबद्ध है।

step 4: Choose प्रदर्शित करता है दाईं ओर सूचीबद्ध है।
