If you have this enabled, when you attempt to project the connect app will open on the receiving PC and show a pin number that you’ll need to type into the project menu on the projecting PC. One other thing that could halt the connection is the PIN security. Try again, and it often sorts itself out. There are a lot of moving parts with this setup, and I have found that on some devices it does fails to connect the first time. Let’s take a look at where things can go wrong next. So if you’ve checked out these things, your receiving device should be showing up in the connect list now. If you have disabled 2.4Ghz on either device it will not work. Miracast can work across 5Ghz connections – we’ll talk more about this – but it needs 2.4Ghz to initiate a connection. However, if you have limited your Wi-Fi adapter to only work on 5Ghz, Miracast will not work. Most Wi-Fi adapters – like the ones in your Surface will transmit on 2.4Ghz or 5Ghz Wi-Fi networks. So don’t turn this one off unless you have to, and remember to turn it back to on when you’re done to save on power!Īnother thing that can stop you from projecting to your Surface is your network adapter settings. If you turn it off, then it will work on battery as well, but that of course has a battery life impact. If this one is set to on, it simply won’t work unless it’s plugged into power. “This PC can only be discovered for projection when it’s plugged into a power source.” The next thing to check is the power option. So it’s usually best to select “Available everywhere on secure networks” unless you’re trying to project in one of those places.

Like at a hotel, airport lounge or shopping center for instance. This setting is there to prevent random people from projecting to your PC while you’re using somewhere in public.

Set the option to “Available everywhere” if your devices are going to be connected to an unsecured Wi-Fi network when you want to project – or if you are not going to be connected to a Wi-Fi network at all. Setting this to private means that a slightly more relaxed firewall setting will be applied, and it should start to show up! The public network profile setting blocks the Miracast connection. If the Wi-Fi network profile is set to public, then Miracast won’t work. If your 2 devices are both connected to a secured network, but the receiver is still not showing up, check the Wi-Fi network properties on the device you’re trying to project to.
