How to connect your notebook laptop computer to your TV

Laptop to TV connection

Laptop to TV

You can connect to the TV using a wired or a wireless option.

Wired connections require a cable from the laptop to the TV. Wired connections are simple and do not require a home network as do wireless connections. Wired connections may not be as elegant as wireless but they work without complicated upgrades of software or apps or other hardware and are much more standard between manufacturers. Most TV and laptops today have HDMI for a wired connection but with wireless, you may find many incompatibilities which may result in not being able to connect.

Wired connection : Laptops for 2023-2024

Use the HDMI or the USB-C ports on the side of the laptop to connect HDMI or USB-C cables to the TV. Use the HDMI input on the TV to connect cable from laptop and select that HDMI input on the TV using the TV remote. Audio and Video are carried by HDMI and USB-C (1080p or 4K).

Use a USB-C to HDMI adapter cable if connecting USB-C to TV.

Cable USB-C to HDMI

Wired - HDMI

Connect HDMI cable from laptop HDMI output port to TV HDMI input port

The computer-to-TV connection consists of an HDMI cable from the computer HDMI output to the HDMI input on your TV. (If you have an older TV and an older laptop, you can connect using VGA video cable and 3.5mm audio cable). Be sure to select the proper input source on the TV.

How to select Display on Windows 10 and 11:

Press the Windows key and the "P" key on your keyboard at the same time. A pop-up window should appear offering 4 options for display, (1) computer only, (2) duplicate, (3) extend and (4) second screen only. Select the option you want. Duplicate option will display on both computer and the TV.

Full-sized HDMI: If your laptop has a full-sized HDMI output, you can use a standard HDMI cable to connect to your TV. Plug one end of the HDMI cable into the laptop HDMI port and the other end of the cable into HDMI input on the TV.

Mini- or micro-HDMI: If your laptop has one of these smaller versions of HDMI you just need an adapter cable to connect directly to your TV.

Thunderbolt, DisplayPort or Mini DisplayPort: All of these usually work with HDMI as well. Thunderbolt is found on many laptops. The first two versions of the connector were the same as Mini DisplayPort, so Mini DisplayPort-to-HDMI cables or adapters should work. Newer versions use the same connectors as USB-C. Full-sized DisplayPort is common to Windows PCs. Again, you need an adapter or cable with this type of connection on one end and full-sized HDMI on the other.

USB-C port: Many laptops have only this kind of port. Usually you will just need an adapter (USB-C to HDMI) and it should work. MacBooks from the last few years should work, as will Microsoft Surface laptops and many others. USB-C uses the same physical connection as Apple's Thunderbolt 3.

Wireless computer to TV

Wireless depends on what computer you have, as well as the built-in capabilities of your TV or the streaming device connected to your TV.

Most laptops today have built-in Wi-Fi capability. Desktop PCs can add Wi-Fi with a USB adapter.

USB Wi-Fi adapter for PC

Most modern TVs have Wi-Fi built-in but if your TV is an older model, you can often add wireless capability with an adapter. You can also get an HDMI wireless transmitter adapter setup so that you do not need a home network. These units use various wireless technologies to transmit audio and video to the TV.

Products tend to work as a brand partner group so if you have Google Chrome browser, Google Chromecast and an Android TV, wireless should work with those products. If you have a Samsung TV with AirPlay 2 and a current Apple computer, Airplay wireless should work for you using those products. Problems occur when using incompatible products.

Apple AirPlay

If you have an Apple computer: The easiest way is to use AirPlay. But you'll need a device that supports it, such as:

Apple TV
Apple TV 4K
A TV that's Air Play 2 compatible, such as a compatible TV from Samsung, Sony, LG or Vizio.

AirPlay Mirroring lets you show whatever is on your Mac or iOS device's screen on an HDTV using the Apple TV. This method is another OS-level feature that's not available as part of Windows, but you can try adding it with 3rd party software.

How do I turn on AirPlay?

To turn on AirPlay on a Mac, select the AirPlay icon in the menu bar and choose your compatible TV. Within apps like Apple Music, Apple Podcasts, or Apple TV, look for the AirPlay icon. To turn on AirPlay on iPhone, open Control Center and long-press Music or tap Screen Mirroring/AirPlay Mirroring.

On a Samsung Galaxy device, the screen mirroring feature is called Smart View. You can easily mirror your screen with Smart View by just tapping the Smart View icon and doing a few simple steps.


If you have a Windows PC you may be able to use Miracast. Your Windows laptop should have it built-in. On the TV side, devices that support Miracast include:

Roku streamers
A handful of TVs, mostly LG models with some Sony and Sharp.
Wireless display adapters that plug into your TV

There are multiple ways to mirror (Duplicate) your Windows 10 desktop to your Smart TV.
1. Press the Windows key and the P key on your keyboard at the same time.
2. If Miracast or another screen share option is available, a few choices to Project to will be displayed.

You can check in the menus of the television itself to see if Miracast or casting is listed as an option. There are a few ways you can check on your Smart TV to see if Miracast is supported.
Check if your Smart TV considers Miracast an app you can run.
Press the Menu button on your remote and select Apps for your Smart TV. Look for "Miracast", "Screen Casting", or "Wi-Fi Casting" apps.

Some TVs consider Miracast another input, rather than an App.
Select Input or Source.
Look for "Miracast", "Wi-Fi Casting", or "Screen Casting".

Miracast is a standard way for a computer, smartphone, tablet, or other device with WiFi to talk directly to a smart display. Check with the WiFi Alliance for certified devices.

Project your Windows 10 or Windows 11 computer to a TV


Make sure your computer and TV have the requirements for wireless projection. Most PCs that run Windows 10 or Windows 11 will support this feature, but to check if your PC is compatible, press the Windows key and "P" key at the same time on the keyboard. A Project action bar will open. To be compatible, this action bar must contain the link "Connect to a wireless display." If it is not there, your device is not compatible.

Most Samsung Smart TVs will support screen mirroring and casting. Make sure that both the TV and PC are operating on the same Wi-Fi network. Setup the TV for wireless and the computer must have Wi-Fi.

Mirror your screen

On your Windows computer, click Start, then type in "Bluetooth and other device settings" and click on it when it appears.

Click Add device or Add Bluetooth or other device. Then, click Wireless display.

If you have a Chromebook: Computers that run Google's Chrome OS can send content to a TV wirelessly. To use it you need:

Chromecast (built-in Wi-Fi, check for max video resolution)
Chromecast Ultra
Smart TVs with "Chromecast built-in," mainly Vizio but also some other brands.
Nvidia Shield
Sony TVs that run Android TV

Casting from a Chrome browser: If you don't have a TV device with AirPlay or Miracast compatibility you can still mirror your screen from the Chrome browser on any laptop. It works with any of the devices from the Chromebook list above. Only content from the Chrome browser will be visible.

Google Chromecast lets you mirror your Chrome browser page on a TV.


Your TV and your laptop's screen are probably different resolutions. Adjust the laptop's output to match your TV's resolution. If you are trying to send audio, that might need to be switched on as well, either by clicking the speaker button in the lower right on Windows, or in System Preferences on Mac. On the TV side, make sure you disable your TV's overscan. It might be disabled automatically, but if the edges of your desktop are cutoff, look into your TV's menus for something like "size" or "zoom." If you're not getting an image on screen at all, try unplugging the HDMI and plugging it back in, and if that does not work, plug it all in, but turn the TV off, wait a few, then on.

Apple Macbook laptop to TV hookup

Many people today want to display their laptop on their HDTV so internet videos can be viewed. More and more video is available on the internet and the laptop screen is nice but the larger HDTV screen is better. Plus you have options for better audio by connecting the laptop sound to better speakers.

You need to do 3 primary things in order to view your laptop display on your home TV screen.

1) Connect a video cable from the laptop video output to the TV video input.

2) Connect an audio cable from the laptop audio output to the TV audio input or home stereo sound system.

3) Setup the laptop computer to be able to use your TV display.

o How to connect an APPLE MacBook to an HDTV using HDMI

Note: If using HDMI connection, both video and audio can be carried over a single HDMI cable.

Also be sure to select on the TV (using the TV remote or button) the proper source, that is the laptop connection. The SOURCE button or INPUT Select is used to switch to the proper input to view the laptop screen.

If using an HDMI connection, select one of the HDMI inputs. If using VGA, select the PC source when navigating through the inputs on your TV.

OPTIONS for hookup:

Today, the HDMI or the VGA connections are best. Almost all laptop computers are designed to be able to use external displays. A laptop computer can have a video output jack such as an S-Video or an RCA composite video or a VGA port or a DVI port or an HDMI output and more. The video output port on your computer could be a VGA output or it could have several options. It depends on what graphics capabilities your hardware has and this determines how you connect to a TV.

If your laptop has HDMI, use that connection. If your laptop has VGA but no HDMI, you will have to use the VGA connection. In both cases you need a male to male cable to connect laptop to TV.

Many modern HDTV display panels such as plasma and LCD have a VGA input port built-in specifically for computer hookup. So you can see that there are many possibilities and options depending on what type of jacks your laptop has and what type of jacks your TV has. Depending on which video output jack(s) your computer has, you can make a direct cable connection or use one of several types of adapters.

PC or laptop to TV adapter for CRT hookup

WIRELESS LAPTOP TO TV CONNECTION - See wireless section towards bottom

You can also make a wireless connection from laptop to TV using a set of wireless boxes, transmitter and receiver, such as the ones here from SewellDirect or here from D-Link and this one has component video, composite video and VGA.

Your laptop's video and audio output jacks are along the back, sides or front of the bottom section of the computer. Your laptop may have one or more of the following ports for video and audio:

STEP 1: Video hookup



STEP 2: Audio hookup
Earphone Audio 3.5mm

Audio Cable has 3.5mm stereo plug for computer connection and at the other end is the two RCA plugs for left and right stereo channels.

Most laptops utilize a 3.5mm (1/8-in) jack as the line output connector and most TV and hi-fi equipment uses RCA type sockets for connecting audio components.

What you need:

  • Laptop computer with VGA, DVI, HDMI or S-video output jack and audio output jack.
  • TV or HDTV with available video and audio input jacks such as VGA or HDMI or S-video.
  • Cable(s) for video and audio.

Connecting laptop to HDTV with VGA and audio cables

VGA male to male cable to connect laptop to HDTV.

The VGA cable is for video only, so audio connections will need to be made for sound, if desired.

Most HDTVs today have a VGA female input port for connecting personal computers. The color is typically blue and it has 15 small openings arranged in three rows of 5 each. Most modern laptops also have this female 15 pin video output port. What you need to connect TV to laptop is a male to male VGA cable. Each end has 15 pins which insert into both female ports on the TV and computer. These VGA cables cost about $15 or so.

Question: My HDTV does not have a VGA input, only HDMI. How can I connect my laptop, without HDMI, to TV?

Answer: Your laptop should have a VGA output. VGA is analog video but the TV's HDMI input is digital video. Therefore no cable connection directly from the laptop to the TV will work, even if the cable has VGA at one end and HDMI at the other end. What you need is a VGA to HDMI converter which accepts the analog VGA video and earphone out audio from the laptop as input and then outputs HDMI video and audio to the TV. Connect to the converter using a VGA cable for video and a 3.5mm audio cable for sound. Connect a HDMI cable from the converter to the TV's HDMI input. Press Fn-f7 or Fn-f4 etc. key on laptop.

Connecting your laptop computer to your TV:

After you make the cable connections from laptop to TV, setup the laptop to be able to use the TV screen.

STEP 3: Setup Laptop

To get an image on the TV, you must configure the laptop computer to display an external signal. Typically, this is done by toggling the "Fn" key + "Fx" where x=1 or 2 or 3 or 4 or 5 or 6 or 7 or 8. The actual function key varies with each laptop computer. Your laptop could be Function key and F8 key. Refer to your computer's User Manual for specific instructions for displaying an external signal. All notebooks should support an external monitor, usually with a high-density D-Shell 15 pin VGA connector. Newer laptops don't keep the external connector live by default, and some don't allow for simultaneous display on both the LCD and an external monitor. You can toggle between the notebook screen and the external display with an Fn key combination. The Fn key is located at the lower left of the laptop keyboard, normally between the CTRL and the ALT key.

Toshiba uses Fn/F5 to toggle between the laptop LCD and an external display. IBM or Lenovo uses FN/F7, Acer varies with the model, using Fn-F5, Fn-F3, Fn-F8, Sony Fn/F7, Dell Fn/F8, HP or Compaq, Fn/F4. There are variations with the age of the laptop and not all manufacturers have standardized on a key combo across the whole range, but you can usually figure it out from the little graphics on the function keys that line the top of the keyboard.

The "Fn" + "Fx" toggles between three settings, laptop display, TV only and TV and laptop together. (Sometimes, laptops do not have enough power to show both the TV and laptop displays, so only a scrambled signal is viewable on the TV.)

Some laptops today have key combinations such as CTRL/ALT/F12 for example which will bring up your graphics options. Press all three keys together.

Right Click on the laptop desktop (main screen) and go to Graphic Properties or Graphics Options.

Matching screen resolution

When you connect a TV or HDTV to your laptop, your laptop display resolution may need to be changed to match more closely the TV's screen display properties. Depending on your laptop's graphic output capabilities, you can try to match the TV's screen so that you see the proper proportions for text and images. Technologies are always changing, so consider the screen resolutions below as a guide only.

1. VGA Video Graphics Array 4:3 640 X 480
2. SVGA Super Video Graphics Array 4:3 800 X 600
3. XGA eXtended Graphics Array 4:3 1024 X 768
4. WXGA Widescreen eXtended Graphics Array 5:3 1280 X 768
5. WXGA Widescreen eXtended Graphics Array 8:5 1280 X 800
6. WXGA Widescreen eXtended Graphics Array 16:9 1366 X 768
7. UXGA Ultra eXtended Graphics Array 4:3 1600 X 1200
8. HD-1080 Full High Definition 16:9 1920 X 1080

Your computer graphics card may only have the first three possibilities for screen resolutions or if you have a newer computer or newer graphics card, you may have greater capability to match the TV's native resolution. HDTV's can have 1920 by 1080 native resolution so only the newest computer hardware can match this video resolution.

WARNING - Be very careful when adjusting screen resolutions and refresh rates as damage could result to your TV. Always read your owner's manual and follow the guidelines and parameters recommended. If in doubt, contact the TV's manufacturer before proceeding to ensure you are operating within the TV's valid parameters.

For Windows PC's, go into CONTROL PANEL, then DISPLAY and click on the SETTINGS tab. Use the slider bar to set the screen resolution you want. Next click APPLY.

For Windows Vista operating system, click START, go to Control Panel, click PERSONALIZATION, then Display Settings Adjust Screen Resolution.

Your screen resolution is the number of pixels in the width and height of your screen (width x height). A higher resolution results in a sharper image, but things will appear much smaller. When changing resolutions, you should consider the size of your monitor. Images may appear to flicker because your monitor can't keep up with the resolution and still provide a sharp image. 1024x768 is one standard screen resolution. 800x600 was a standard screen resolution. 640x480 is another, out of date, screen resolution.

In addition to your screen resolution, you should also consider the number of colors to display. Adjust the slider to increase or decrease resolution, and then click "Apply." Windows will pop up an info and warning screen. Click "OK." The screen will go blank and then come back in the new resolution. Windows will ask if you want to keep the settings. Click "Yes" or "No". If you end up not liking the new resolution, you can change it back to the old setting. When done, click "OK" to close the display properties window.

Refresh Rate
If your screen looks very bright, you may need to adjust your monitor's refresh rate (this is the speed at which the monitor "refreshes," or redraws, the image). Standard television refresh rate is 60 Hz. To change the refresh rate, click the "Advanced" button in the "Settings" tab in the "Display" control panel. Read your TV owner's manual to determine your TV's possible refresh rates and DO NOT EXCEED the values.

Troubleshooting tips:

If you have Windows Operating System,
click START -- CONTROL PANEL -- DISPLAY -- Then in Display Properties click SETTINGS Then ADVANCED.
In the MONITOR tab and the DISPLAY DEVICES tab, you can adjust properties if needed. In the DISPLAY DEVICES tab you should see both the TV and the laptop displays with check boxes you can fill in. Additionally you may require device drivers if you don't already have them installed in the laptop. Also in your laptop BIOS, make sure you have TELEVISION OUTPUT enabled and that you have NTSC selected for analog TV sets.

HDTV with HDMI connection:

Some graphics cards (video cards) have an HDMI port so you can use an HDMI cable to connect the laptop to the HDTV. The key here is to install the proper drivers for the card (if not already installed on the computer) so that you can use the newer software attributes to fine tune the HDTV connection.

One example of a modern laptop with HDMI output is:

Dell Studio XPS 16
multimedia laptop

* Full 1080p HD support and premium ATI graphics.
* 15.6" LED or optional 16" RGBLED seamless display.

ATI Mobility RADEON HD 4670-1GB

9. Click OK to close the window.

How to view NETFLIX on HDTV instantly via internet connection

Instead of going to the store to buy a DVD or waiting for a DVD to arrive in the mail from Netflix, why not view the movie instantly over the internet on your HDTV. You need a broadband internet connection, router (wired or wireless) and subscription with Netflix, plus an HDTV, computer and cables. Many people already have high-speed internet service with their TV provider and have an HDTV and laptop. Some even already have NETFLIX service and are getting DVDs in the mail.

Netflix’s “watch instantly” streaming internet video service allows you to view a movie now without waiting for a DVD to arrive in the mail. It’s easy to watch a Netflix movie on a computer screen, but now you can watch from the comfort of the couch on the giant plasma or LCD HDTV. You just need to hookup the computer/laptop to the TV.

Your broadband download connection should be at least 10 Mbps for good video. Check your speed here. and click on Begin Test.

Also, there are TV shows and movies available from sites like,,, amazon video, itunes,,,, and others.

The image below shows the ports on a modern laptop including HDMI.

SELECT proper TV input source:
You must select the source on the TV where the cable from the computer is connected. Usually the TV remote is used to select the source so that you get the output from the computer.

Tell the computer to use the external display:
Refer to your computer’s user guide for the specific keystroke for selecting an external display. On the HP Pavillion laptop for example, press Fn + F4 keys together to toggle between the laptop display, laptop and external display (TV), and external display (TV) only. On a Dell, the key combination is Fn + F7.

Configure the sound output on the computer:
With HDMI, you need to setup the computer so that the audio will output over HDMI. With a Windows computer, go into CONTROL PANEL and then into Sound and select the digital sound out so that the default is sound out via the HDMI port. Windows Vista O.S. allows you to TEST the audio so that you can hear the sound thru the TV speakers. Go into PROPERTIES, then ADVANCED and click on TEST. You can also adjust the sound volume. Other adjustments may also be needed in order to fine tune the sound such as the rate (48kHz) and setting DVD QUALITY SOUND instead of CD.

Other adjustments may be required such as cancelling the screen saver and/or power saving modes/sleep mode so that the computer does not enter sleep mode or any kind of power save mode due to inactivity while you watch the movie.

Speed of internet service:
You need a speed of 6 Mbps or more to get acceptable viewing.

Connecting home theater system speakers:
Run a digital audio cable from the HDTV into your home theater system so that you get richer sound from the loudspeakers instead of the TV speakers. Adjust the volume.

HDMI cables:
HDMI cables should cost about $10 or so. The more expensive HDMI cables are nice but the cost is too much. Try buying HDMI cables at before going the $100 HDMI cable route.

WiCast is USB powered, so there is no need for an extra adapter. Users simply plug the device into the HDMI port and the two USB ports of a laptop for power. This feature allows users to avoid the hassle of messy wires and the need to look for and be tied to power sockets.

Omni-Directional Broadcast
WiCast supports a range of up to 33 feet and WHDI transmission is not limited by directionality or line of sight. These features provide users in the education or business sector with more flexibility and convenience when connecting notebooks wirelessly with the projector to display presentations.

Small Package
At just over 4” long (both the transmitter and the receiver), WiCast is small enough to virtually disappear behind a notebook or on top of a projector, eliminating cluttering and promoting space efficiency. Lightweight, at a mere 0.242 lbs.(transmitter) and 0.352 lbs.(receiver), WiCast is easy to carry anywhere.

WiCast utilizes Wireless Home Digital Interface (WHDI) technology to wirelessly transmit high definition video and audio signals from a user's notebook to a display TV or an LCD monitor. WiCast supports latency free (less than 1ms) transmission, providing users with fluid and stutter-free playback of HD content. Low latency prevents "lip-sync" issues and enables smooth delivery of HD content. WiCast is USB powered, so there is no need for an extra adapter. Users simply plug the device into the HDMI port for a signal and two USB ports for power.

ASUS WiCAST is very small and lightweight. Everything you need is included. Transmitter, Receiver, cables and power adapters. 


Intel has a solution, WiDi for wireless display, that requires the laptop to have Windows 7 (64-bit) and the latest processor (smart 2nd generation Intel Core processor) and Wireless Display technology. You also need to buy a box like the Netgear PUSH2TV. The current release will not let you play DVD or Blu-ray to the TV. Intel is currently working on a new version of the technology (most probably WiDi 3.0), which will feature support for connecting a maximum of two monitors simultaneously.

WiDi enabled Laptops:

• HP Pavilion dv6-3150us
• Dell Inspiron 15R i15RN5110-7223DBK
• Lenovo Z570 10249LU
• HP Pavilion dv6t QE
• Lenovo Z570 10243WU
• Lenovo Z370 102527U

Question: I want to connect my laptop to my HDTV with HDMI but my HDTV speakers are not the best sound, how can I connect so that the sound goes to my home theater sound system?

Answer: Buy a switcher which allows HDMI input and HDMI output to HDTV but also has audio outputs for a stereo or audio/video receiver so a richer sound system can be used. See the switcher from below.

Question: My laptop only has VGA out and my HDTV does not have VGA input. Can I still connect laptop to HDTV?

Answer: Yes, if you get an adapter box. The SW-9393 from or can take the VGA in and send out HDMI. The HDMI is limited to 720p on this box but more expensive adapters (SW-20505) offer 1080p. The Sewell SW-4280 box accepts VGA in and outputs component video for older TVs or TVs without HDMI. The Sewell SW-23000 box will accept VGA in and output composite video for CRT tube TVs. The Sewell VGA to RCA box for $20 accepts VGA in and outputs the yellow RCA video for TV or VCR. Just connect laptop earphone out to audio input on TV or VCR/DVD recorder and enjoy!

For TVs with only a RF coax input jack, use an RF modulator connected to the adapter's yellow video output and select channel 3 on the TV.

Question: I have an older CRT TV, analog NTSC with composite video (yellow) input and I want to hookup my computer so that I can see the display from the computer on the TV. What do I need for this? Thanks, Tom K.

Answer: There are several video adapters you can buy which will accept a VGA input from the computer and output composite video. Connect an audio cable from computer to TV for sound. One example of a basic adapter to do this is reviewed here.

Question: Can I use a cable with a VGA connector on one end and a composite video (yellow) RCA connector on the other end to hookup my computer to my analog TV.

Answer: No, this will generally not work because the signals are different. You need to use a converter/adapter unit to convert from VGA to composite video.
