Introduction

Maybe you want to show someone a funny video that got you laughing, some photos from your latest vacation, watch a movie or a sports game from your computer. Maybe you want to show a business presentation. You don't have to crunch over and huddle around your monitor in your office or on your desk, but you can instead enjoy all that on your big screen TV.

When it comes to connecting your computer to your TV, you've got a wireless device that can help. Many modern desktops now come with wireless cards and internal bluetooth adapters, allowing you to easily cast or send your desktop to your big screen. However, if your computer doesn't come with that technology, you can easily use a Wireless Video Adapter to do the same thing.

What Is a Wireless Adapter Kit

Wireless video adapter kits vary in shape, size and connectivity. Refer to the computer's and display device's documentation to ensure you match the audio/video output and input ports they have.

A wireless video adapter will essentially connect the your computer and television using the same audio/video ports you would use when connecting a cable between them. The computer needs to be connected to the wireless transmitter, whereas the display device needs to be connected to the wireless receiver.

Microsoft Wireless Display Adapter

Microsoft has their own video adapter kits, set up especially for Windows computers.

Their adapter uses an HDMI and USB input connected into your Smart TV to enable it to connect to your Windows computer. Then, using Miracast on your Windows system, you would send your desktop to your TV.

Wireless HDMI

Wireless HDMI extenders send HDMI data wirelessly between a transmitter and receiver, letting you connect your computer to a nearby small box with a short HDMI cable, and your TV to another nearby small box with another nearby HDMI cable. This way you're not stringing cables across your house but still get the same effect. Unfortunately, these extenders are expensive and can have considerable lag. That's not a problem if you're watching movies but if you're playing a game it can cause issues.
