The technology has come a long way. Earlier, we used to connect our devices using cables, but now, many devices can be connected wirelessly. One such wireless technology is Miracast. Using Miracast, you can connect your computer’s screen to a TV screen, projector and media players. This is basically HDMI over Wi-Fi. To connect the devices the other device must be a Miracast compatible device, that’s it. This technology has become very useful in the past few years. People use it for presenting slide shows, to playing games and watching movies on the large TV screen.
You can do the same. You might have this technology already on your computer, and you might not know it. But, if your computer’s a little old or this tech did not come preinstalled on your system, there is another way to fix it. How? We will show you how to setup Miracast, along with what to do if it stops working.
