There are several reasons why you may want to connect your Laptop Computer to a big screen TV, considering that there are so many interesting video resources such as YouTube. Here are various ways to make this connection work.
If you’re tired of squinting over your laptop screen or if you’ve recently bought yourself a new flat screen TV, a much better option is to route the computer display to your television screen.
And in case you’re wondering if there’s an easy way to do this, there are several ways to do this depending on what ports are available on your computer and television.
Jargons Explained: S-Video, VGA, DVI, HDMI
Before we go into the details, here’s a brief overview of the various connection options that are usually available.
Most computers have an S-Video port that can be connected to the S-Video input of your TV screen using an inexpensive S-Video cable. The S-Video port allows you to connect your laptop to both analogue and digital TVs. On older monitors, you can use the 15-pin VGA cable to connect the computer to the TV and it will offer slightly better picture quality compared to the S-Video cable.
S-Video doesn’t provide High Definition (HD) quality, and only carries the video signal, so you’ll also need to hook up a separate audio cable – typically from your laptop’s 3.5mm headphone jack – to the audio inputs on your TV.
VGA is an old standard and uses analogue signal that can’t be converted into digital signal, which is what HDMI and other digital standards such as DVI use (you can use adaptors however to change between formats).
Your TV will need one of two things: either separate S-Video and phono audio ports, typically found on the front of the TV, or a SCART socket found on the back. You’ll then need to purchase an S-Video cable of suitable length, along with a suitable audio cable. If necessary, you can then purchase a SCART adapter to connect the cables to your TV.
The newer HDTVs and laptop computers have DVI ports, so a DVI Male to Male Cable or DVI to HDMI Adapter Cable (If your HDTV doesn’t have a DVI port but does have an HDMI) can be used.
For older laptops with VGA output, there are VGA to HDMI and VGA to s-video converters available but they can be expensive, and can require lot of effort to get the connection working. VGA is analogue and it doesn’t convert well.
The best option is to get laptop / television with newer technologies (HDMI), which is the easiest way. It means the laptop (Mac/PC) and the TV needs to be HDMI enabled, in which case the Television easily detects the computer once the connection is made and you’re ready to go.
Various Connection Options
To give a summary, these are some of the most common connection methods depending on the equipment you have:
Connecting the Audio
Once the computer is connected to the TV via the video cable, you need to connect the mini-to-RCA cable from your computer’s headphone jack to your TV.
Adjusting the Display Settings
On a PC, under Control Panel, you can do the adjustments to the display settings and select the option to display on both your monitor and TV set.
For Mac, you need to go under System Preferences, click on Display, and then Detect Displays.
Finding Your laptop on the Televisions
Next, you need to select your TV’s video source, usually a button called “input” or “TV/Video” on your remote, until your laptop comes up. Once your computer is selected, you’re done!
How to Proceed
So the very first thing you need to do is to check the input and outputs on your computer and TV, to help you buy the right cable.
If you have a high definition TV, you’ll want to use a DVI cable or an HDMI cable. If your PC is a bit older, then it may only be able to use VGA cables, so it’s important to check your TV has the right connections for VGA, which most do.
In the event that your TV set uses one kind of connection and your computer uses a different one, you’ll need to get an adapter (available on most stores) as per the cable input that you have to use.
Standard definition TVs typically allow S-video cable connections, so for those who have not made the move to HDTV’s, this might be the only option.
There are various gadgets available now that let you connect your PC to your TV via WI-FI. Although this might be the ideal choice, it does require additional equipment.
At times your TV may not recognize your computer’s connection. In that case, confirm your laptop or computer is switched off before inserting the lead into your TV. Then plug the lead back into the TV set and restart your system. Now, the connection should ideally be recognized. If this doesn’t occur on the first attempt, try this step a couple more times until the connection has been established.
