How to Watch what is on your Computer Screen on a Television

Lets say you watch a show on your computer and you want to see on any television.

You can do this an a budget by buying simple electronic components for about $100. 

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 'headphones' connector.. 

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 television

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 the "PC 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, 1280x1024)
  • 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 picture)

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 monitor 

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 the PC-TV85


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 extenders".

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 signal format


In this example we use the Lorex Model No: "VS6438" Wireless AV Sender

More information and links to buy this product can be found on the VS6438 page of our site.

You can 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 receivers. 

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 extender
  • 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 "Audio 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 Sender-Transmitter.

At this point the transmitter will send over the air both audio and video

When you connect the Wireless AV Sender 'receiver' to any television, the transmitted signal the computer will be shown on the television

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 television

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
