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
2) Connect an audio cable from the laptop audio output to the TV audio
input or home stereo sound
3) Setup the laptop computer to be able to use your TV display.
video and audio can be
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
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.
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
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
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.
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:
1: Video hookup
2: Audio hookup
You can buy cables already made
specifically for connecting laptops to
a TV. The cost should be under $15.

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.
HDTV does not have a VGA input, only HDMI. How can I connect my laptop,
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.

How to connect Apple MACBOOK to HDTV with HDMI
There are at least two adapters with HDMI to choose from. The first one
is short and has the Mini Display Port plug on one end and a HDMI
female port on the other end. You use your own HDMI cable of chosen
length. The second is a longer cable with HDMI male on one end and mini
display plug on the other end. See the YouTube video above for step by
After you make the cable connections from laptop to TV, setup the
laptop to be able to use the TV screen.
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
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
Right Click on the laptop desktop (main screen) and go to Graphic
Properties or Graphics Options.
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.
Video Graphics Array 4:3 640 X 480
SVGA Super Video Graphics Array 4:3 800 X 600
eXtended Graphics Array 4:3 1024 X 768
WXGA Widescreen eXtended Graphics Array 5:3 1280 X 768
WXGA Widescreen eXtended Graphics Array 8:5 1280 X 800
WXGA Widescreen eXtended Graphics Array 16:9 1366 X 768
UXGA Ultra eXtended Graphics Array 4:3 1600 X 1200
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
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
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
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.
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
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.
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:
Studio XPS 16
* Full 1080p HD support and premium ATI graphics.
* 15.6" LED or optional 16" RGBLED seamless display.
ATI Mobility RADEON HD 4670-1GB

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.
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.
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.
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.
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 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

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
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
offer 1080p. The Sewell SW-4280 box accepts VGA in and outputs
video for older TVs or TVs without HDMI. The Sewell SW-23000 box will
accept VGA in and output composite video for
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
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
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.
