Connecting a TV to a computer wirelessly is almost always better than using a cable. It’s safer for the devices because chances are, someone is going to trip on that wire. It’s also a lot smoother, especially if you plan on disconnecting and reconnecting them regularly.
That said, it’s essential to know that the reliability of wireless connections largely depends on the strength of the WiFi signal. You might face issues like delay or freezing if your WiFi isn't very strong or the distance between the devices is too big.
Connecting to a Smart TV
Just about every smart TV model out there comes with WiFi network compatibility. They can be connected to a laptop or PC through casting or screen sharing.
For Windows 8 & 10 PCs and Laptops
For this method, both devices need to be connected to the same WiFi network. To connect your specific TV model to a WiFi network, check the user manual or go through the settings menu. You’ll most likely find it under “Network and connection.”
Once you’re done with that, it’s time to connect your laptop.
Press the Windows button + K on your laptop. This will open the “Connect” side panel.
Click on your TV’s name when it shows up on the list of devices. It’ll likely be the brand + model number or the name you set up when you first got the TV.
Once connected, hit the Windows button + P to view projecting options.
Choose “Extend” if you’d like to be able to put different windows on each screen, “Duplicate” if you’d like both screens to show the same thing, or “Second screen only” if you’d like to turn off the PC screen.
Unfortunately, MacBooks are not as easy to connect to a smart TV without an Apple TV. If that’s not an option, then you might have to experiment with third-party software that works for your specific TV brand. Alternatively, you can just use a wired connection.
If you do have an Apple TV, though, this connection is as easy as a click of a button.
First, make sure your TV and Apple TV are on.
On your Macbook, click on the Apple logo on the upper left corner of your screen.
Open “System Preferences” and find the “Displays” section.
Find your TV in the “AirPlay Display” section.
Connecting to a Non-Smart TV
To connect your computer to a non-smart TV, you’ll most probably need the aid of a media streamer like Chromecast or Apple TV. These are usually USB drive size gadgets that can basically turn your TV into a computer. There are lots of options on the market depending on your budget and what you need your TV to be able to do without your computer connected to it.
How to connect these depends on what brand you choose to go with.
