|How to Watch what is on your Computer Screen on a
Lets say you watch a show on your computer and you want to see on any
You can do this an a budget by buying simple electronic components for
What you will Need
- A "PC to TV device" about $40
- A "Video Sender device" about $50
- A Sound Card audio cable under $10
With this method, you would use a bypass electronic component called a
"PC to TV device" to capture the video signal from your VGA
cable coming out of the computer, and audio from your sound card
This device will have RCA jacks for Video and audio commonly known as
composite cables which can be used to connect to a second device called an
'Wireless AV Sender.'
The Wireless AV Sender sender is a kit which comes with a 'transmitter'
and a 'receiver'. You can simply connect the AV cables from the output of
the 'PC to TV device' to the AV cable input of the 'Wireless AV
Sender-Transmitter' which will send both the video and audio on the
airways. The transmitter has a limited range of up to 300 feet if
unobstructed and in reality about 50 feet inside a house.
Then you would connect the 'AV output' of the 'Wireless AV
Sender-Receiver' with a second set of A/V cables to an input of the
The Wireless AV Sender-Transmitter and receiver can be operated
on any of 4 different frequencies, so as long as they both are matched,
the computer video and audio will be shown on the television.
A detailed explanation of the above is shown below
1. the 'PC to TV device'.
There are a number of these devices which you can find by going to
to TV devices" page on our site.
In this example we will use the Sabrent model PC85 shown below
You can get more details, prices and a place to by this product , by
going to the 'PC-TV85"
page on our site.
this device has a video input, an audio input, a power plug (gets
power from a USB port with an included cable) and A/V output connectors,
it also acts as a pass-through from the computer VGA port to the monitor
Features of the PC-TV85
- VGA In - Imports VGA signal comes from your PC or MAC (Resolutions: 640x480, 800x600, 1024x768,
- Composite Out (Yellow RCA) - Connects to the TV (option 1)
- S-Video Out - Connects to the TV (option 2)
- Dip Switch to adjust NTSC/PAL - NTSC for North America (default); Compatible with NTSC-EIAJ, PAL-M, PAL-N)
- VGA Out - pass-through port used to connect a VGA monitor in addition to the TV
- DC 5V Power Input - Included USB cable draws power from an available USB port on the computer
- No drivers or software needed
The connection is as follows.
a) you disconnect the VGA cable from the monitor and instead plug it
in the 'VGA in" connector of the 'PC-TV 85" (see top left
b) you use the provide VGA cable and connect it to the "VGA
Out" connector of the "PC-TV85" and the other end to the
c) you connect the provided USB cable to any USB port on the computer
and the other end to the power plug shown above on the bottom right
picture (to the left of the red '12' switches)
At this point, your computer monitor will operate as it did before,
the signal will come out of the computer VGA video connector, go into
the "PC-TV85" box and then leave the box and end up on the
monitor, and since the box is powered from the USB plug the monitor
works as usual.
d) Remember at this point only "video out" is provided by
2. The 'Wireless AV Sender' kit
We list several "Wireless AV Sender" products on on
our site at the "AV
Sender Products" page. These are sometimes also called "AV
The older models send the signal in the older SDTV (standard tV)
format, newer models found here Type
- USB to HDMI connect to the HDMI port and send the HDTV
In this example we use the Lorex Model No: "VS6438" Wireless
More information and links to buy this product can be found on the VS6438
page of our site.
connect a second receiver to another television and be able to watch on
both (or more) at the same time. A single transmitter is all you need,
to send out the signal and then it can be picked up by one or more
This device also has a 4-channel capability so as long as the
receiver and transmitter are on the same channel, you can technically
run up to four transmitters at once.
On a side note, the channels used on these devices are the same as
the product you might also know as "wireless baby monitors"
which you can buy at most retail stores. The receiver of these baby
monitors can also pick up the signal of your computer.
This means that if you live in an apartment and watch your computer
on your TV, your next door neighbor can also watch the signal you send
out (within 50 feet or so).
This product has the following specifications
- 2.4 GHz Wireless 4-channel Transmitter/ Receiver
- IR Extender
- Incluades receiver, transmitter, 2 RCA cables, 2 power supplies
(9V), 1 Coaxial cable
- Up to 300 ft wireless transmission (open space)
- Send signal to a second TV from Satellite, DVD, Security Camera
- Change TV Functions from remote location using remote control
- View video from another room
- 300 ft Wireless Transmission (open space)
- 2.4 Ghz Wireless Transmission
- Crystal clear Video and Stereo audio
- 4 Channel Wireless System
- Includes: Receiver, Transmitter, IR extender2 RCA Cables, Coaxial
cable and 2 Power supplies
Basically you connect the 'Transmitter's" Video input (an RCA
jack) to the "PC Converter's" Video output. At that point the
signal is on the air.
You then connect the "Receivers'" video output to the
television's Video Input and switch the television to that one input
which you used.
3. Connecting Audio to the Wireless AV Sender.
All you need now is Sound
In order to provide audio to the Wireless AV Sender, you can
use the computer's sound card connector. You would need a cable that has
a headphone jack (ie speaker plug) on one end and 2 standard RCA
connectors at the other end. You can find such cables on our site on the
cables-3.5mm RCA" page or our site
One such example is this Belkin F8V235.
The 3.5mm connector will go the the sound card "audio out' /
headphone connector and the white and red RCA plugs will plug into the
Input of the Wireless AV Sender-Transmitter.
3. The setup of all components
The completed setup will have the VGA cable leaving the computer and
going into the PC to TV converter and another VGA cable leaving the PC
to TV converter and going to the monitor
The Video cable will go out the PC to TV converter and into the Wireless
AV Sender-Transmitter video input
The sound cable will leave the headphone jack of the computer and
connect the white and red plugs to the TV Wireless AV
At this point the transmitter will send over the air both audio and
When you connect the Wireless AV Sender 'receiver' to any
television, the transmitted signal the computer will be shown on the
In cases where you are watching movies on the computer, you can
maximize the screen so that only the movie is shown.
Below is a picture of the completed setup
The above shows the connection to the computer, at the other end (the
television) you would connect the A/V Receiver using Composite A/V cables
which will pick up the signal from the computer and feed it to the
Some computers have RCA connector video output on the video card. In
this case you can eliminate the use of the PC to TV Converter and simply
connect the Video connector of the Video card of the computer to the
Transmitter and the Sound Card to the transmitter's audio RCA connector
