plex desktop

People who have created a sizable library of movies on their laptop can very easily stream them directly to their TV with Plex.

This platform will catalog all your audio or video files and then permit you to stream them to any other device that has the Plex app.

Many of the newer Smart TVs support the Plex platform.

The basic form of Plex is free of charge while more advanced features will cost you a monthly fee of $4.99.

Q & A

What do I need to physically connect my laptop to my TV?

To physically connect your laptop to your TV you will need an HDMI cable.

You will also need a TV which has at least one HDMI port. All Smart TVs will provide you with HDMI ports.

Your laptop will also need to have a port to take your HDMI cable.

All laptops manufactured in the last eight years will provide you with an HDMI port (except for Macs they use USB-C).

You can buy all sorts of HDMI cables at a range of prices. However, you don’t need to spend a lot of money to get a quality cable.

You should be able to pick up a very decent gold plated cable for about $10.

How do I connect a Macbook Pro to my TV?

If you have a new version of the Macbook Pro, it will have come with a USB Type C Adapter that will enable you to connect to your TV.

You can then purchase a USB-C Adapter to HDMI Adapter. Options available are the Anker Adapter and the more expensive Digital AV Multiport Adapter.

Your MacBook Pro will come with a Thunderbolt Port that is able to also serve as a Mini Display Port.

Does TV inherit the laptop’s resolution?

Inbuilt netflix on TV

No, the TV will not automatically inherit the resolution settings from the laptop.

To get the best picture you can lower the settings on your laptop to something like 1280 x 720.

Alternatively, simply switch off your laptop’s resolution settings and just go with the ones on your TV.

Can you play movies via your laptop on your TV?

Yes, you can play movies via your laptop on your TV.

You can set up your connections between the laptop and the TV either wirelessly as shown in this article or with the aid of an HDMI cable.

Keep in mind, however, that many Smart TVs now come with built-in NetFlix and YouTube so you may not have to stream from your laptop at all.

What if I don’t have an HDMI port on my laptop or my TV?


If you have got an older TV or laptop, you will not be able to use a cable with HDMI to HDMI ports.

But there are other options.

Check both your TV and your laptop ports.

If one has an HDMI and the other has a VGA port, then you will simply have to purchase an HDMI to VGA cable.

You can also purchase a VGA to VGA cable.

Should I get a mobile streaming device or buy a cable to stream my laptop on my TV?

Amazon Firestick

If your TV does not have HDMI ports then using a mobile streaming device will allow you to stream your internet screen on your TV.

The most popular mobile streaming devices are Google Chromecast and Amazon Firestick. These devices will cost you between $35-$55.

A mobile streaming device will also require that your TV is internet capable.

Buying a cable is a cheaper option but it means that you will be physically bound at the TV. In the end, it is a matter of personal preference.


Connecting your laptop to your TV wirelessly will provide you with the freedom to move your laptop around while also giving you the big screen TV experience. We provided you with a range of options to allow you to easily set up your wireless TV viewing. So, stop reading and get watching!
