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 have HDMI ports 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 2024-2025
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.
Select the correct input source on the TV with the TV remote.

How to connect your laptop to your TV via 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.
Optional:
If you're on a Windows PC, right-click the desktop and choose Display Settings.
Scroll down to the "Multiple Displays" —you can choose to show the same thing on both screens,
extend your laptop's display to the TV, or show your desktop only on one of the two screens. Click on DETECT if the automatic connection
does not occur. ADVANCED DISPLAY SETTINGS is another option to set resolution.
Click the square that corresponds to your TV, then scroll down and make sure Display Resolution is set to the right numbers (1920x1080 for 1080p TVs, 3840 x 2160 for 4K TVs)
If you're on a Mac, go to System Preferences > Displays and click on the Arrangement tab.
Here you can check the Mirror Displays box to show the same thing on both screens, or uncheck this option to
extend the desktop across both monitors. If you choose to show the image on both screens, go to the Display tab, open the "Optimize For" dropdown, and select your TV from the list.
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.
Airplay, Miracast and Chromecast are the wireless standards for projecting wirelessly from computer or phone to TV.
Airplay is the Apple product while Miracast
is the Windows product. Google uses Chromecast. Many manufacturers incorporate these wireless technologies into their products but
not all have the same wireless built-in. For example a Samsung TV may have Airplay but not Miracast. You can get a specific adapter
for your TV and plug it into an HDMI port. Many modern TVs have some wireless casting built-in along with Wi-Fi capability.
• Adapter for wireless to TV
Wireless HDMI Display Dongle Adapter - Stream from Laptop, PC, or Smartphone to HDTV/Projector - No Setup or Apps Required - Compatible with iOS, Android, Windows, MacOS
Supports Airplay mirroring for Apple iOS/MAC and Miracast for Android/Windows, providing versatile connectivity.
Apple AirPlay
How to use Airplay to connect your Apple laptop to your smart TV:
If you have a smart TV with AirPlay 2 (most TVs manufactured in 2019 or later), you can use AirPlay to connect your laptop to your TV wirelessly.
Ensure that your laptop is connected to the same Wi-Fi network as your smart TV with AirPlay 2.
Go to the Control Center (the icon with the two switches in the top right corner) on your Mac.
Tap Screen Mirroring.
Select the device with which you want to share your display.
Click Screen Mirroring, then select Stop Mirroring to end your streaming session.
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.
Miracast
How to Use Miracast
Step 1: Make sure both your source device (computer or phone) and display device (TV) support Miracast.
Step 2: Turn on the Wi-Fi on both devices and connect them to the same Wi-Fi network.
Step 3: On your source device, go to Settings > Display > Cast Screen or Wireless Display.
Step 4: Select your display device from the list of available devices.
Step 5: Follow the on-screen instructions to complete the connection.
Newer TVs that support Miracast use brand names such as Samsung AllShare Cast or LG SmartShare.
How to turn on Miracast on Samsung TV
On the TV go to SETTINGS, then GENERAL, then NETWORK. Be sure TVs Wi-Fi is connected to your network.
How to turn on Miracast on Windows 10
On source device, be sure Wi-Fi is turned ON. Computer must have Wi-Fi and be ON. Next, click on the square at the
far bottom right of your computer screen. Next click on CONNECT. A search will begin to find display devices such as your TV.
If your TV can support Miracast and it is on your Wi-Fi network, it should show up on the list of devices and you can choose
your TV. A wireless connection from computer to TV screen is now completed.
If the Connect button in the action center doesn't find your device, try the following:
Make sure the display you want to project to supports Miracast
and that it's turned on. If it doesn't, you'll need a Miracast adapter (sometimes called a dongle) that plugs into an HDMI port on the TV.
Make sure your device drivers are up to date and the latest firmware is installed for your wireless display or adapter.
Restart your computer and the wireless display or adapter.
To remove the device on Windows, select Start > Settings > Devices > Bluetooth & other devices.
Under Wireless displays & docks, select the wireless display or adapter, then select Remove device > Yes.

The text will not appear if you do not have any compatible displays.
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.
Apps
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.
Input
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.

Google
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.
Settings
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.

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

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:

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.

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. http://www.speedtest.net
and click on Begin Test.
Also, there are TV shows and movies available from sites like
www.cbs.com, www.clicker.com, hulu.com, amazon video, itunes,
tvland.com, history.com, crackle.com, 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 www.monoprice.com
before going the $100 HDMI cable
route.

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.

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 monoprice.com
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
sewelldirect.com or Amazon.com 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.
