What Is the Connect App in Windows?
The Connect app is a Windows component used to turn your PC into a wireless display receiver. When it is available and configured correctly, another device can project its screen to your computer without an HDMI cable. In modern Windows builds, this functionality is provided through the Wireless Display optional feature and the Projecting to this PC settings page.
In practice, the app is used for screen mirroring, presentations, quick device testing, and displaying content from another Windows PC, Android device, or Miracast-capable source. It is not the same as Remote Desktop: the Connect app is mainly for projection and display sharing, not for full remote administration.
If you search for Connect and cannot find it, the feature is usually not installed. Install Wireless Display from Optional features, then configure Projecting to this PC.
Connect App vs. Wireless Display: What Changed?
Older guides often refer to the Connect app directly. On many current Windows installations, however, the user-facing feature appears as Wireless Display. After the Wireless Display optional feature is installed, Windows enables the receiver components used by the Connect/Wireless Display experience.
This is why different names may appear in search results, Settings, and troubleshooting dialogs:
- Connect app — the older or commonly used name for the receiver app.
- Wireless Display — the optional feature that installs the projection receiver components.
- Projecting to this PC — the Settings page where you control whether other devices can discover and project to your PC.
- Cast or Project — the action used on the sending device to connect to your PC.
System Requirements for Windows Connect App and Wireless Display
Before installing or troubleshooting the Connect app, make sure the PC supports wireless projection. The most important requirement is Miracast support. A computer may run Windows 10 or Windows 11 perfectly but still fail to receive projection if the Wi-Fi adapter or display driver does not support the required technology.
| Requirement | Why It Matters |
|---|---|
| Windows 10 or Windows 11 | The Wireless Display optional feature is available in supported Windows editions and builds. |
| Miracast-capable Wi-Fi adapter | Wireless projection relies on Wi-Fi Direct/Miracast, not only on standard internet connectivity. |
| Compatible graphics driver | The display driver must support wireless display output and encoding. |
| Enabled wireless networking | Wi-Fi must be turned on even if the PC is also connected through Ethernet. |
| Private or trusted network profile | Discovery and firewall behavior are usually more reliable on trusted networks. |
How to Check Miracast Support
- Press Win + R, type
dxdiag, and press Enter. - Click Save All Information and save the text file.
- Open the saved file and search for Miracast.
- If it says Available, your hardware and drivers are likely compatible. If it says Not Supported, update drivers or use another device.
How to Install the Connect App on Windows 11
On Windows 11, the Connect app functionality is installed by adding the Wireless Display optional feature. You can do this from Settings.
- Open Settings using Win + I.
- Go to System → Optional features. On some builds, you may find it under Apps → Optional features.
- Next to Add an optional feature, click View features.
- Search for Wireless Display.
- Select Wireless Display, click Next, then click Install.
- After installation, return to Settings → System → Projecting to this PC.
After the feature is installed, type Wireless Display or Connect in Start search. The visible app name can vary depending on Windows version and language pack.
How to Install the Connect App on Windows 10
In Windows 10, the steps are similar, but the Optional features interface may look slightly different depending on the build.
- Open Settings.
- Go to Apps → Optional features.
- Click Add a feature.
- Search for Wireless Display.
- Select it and click Install.
- Go to Settings → System → Projecting to this PC to configure receiver options.
Install Wireless Display with PowerShell or DISM
If the graphical Settings app fails, you can try installing the feature from an elevated terminal.
DISM /Online /Add-Capability /CapabilityName:App.WirelessDisplay.Connect~~~~0.0.1.0To remove the feature later, use:
DISM /Online /Remove-Capability /CapabilityName:App.WirelessDisplay.Connect~~~~0.0.1.0How to Configure Projecting to This PC in Windows
Installing Wireless Display is only the first step. You also need to allow other devices to discover your PC.
- Open Settings → System → Projecting to this PC.
- Set Some Windows and Android devices can project to this PC when you say it is OK to an available mode.
- Choose whether projection is allowed everywhere or only on secure networks.
- Enable Ask to project to this PC for better control.
- Use Require PIN for pairing if you want to prevent accidental or unauthorized connections.
- Launch the Wireless Display/Connect app and keep it open while connecting from the sending device.
Do not leave your PC discoverable on public or untrusted networks. Use PIN pairing and confirmation prompts if you enable projection in shared spaces such as offices, classrooms, or public Wi-Fi networks.
How to Use the Connect App for Screen Mirroring
Project from Another Windows PC
- On the receiving PC, open Wireless Display or Connect.
- On the sending PC, press Win + K.
- Select the receiving PC from the list of available displays.
- Confirm the connection request on the receiving PC.
- Choose whether to duplicate, extend, or use the second screen only from the projection options.
Project from an Android Phone or Tablet
Android device manufacturers use different names for screen mirroring. Look for options such as Cast, Smart View, Wireless Projection, Screen Cast, or Miracast.
- Open the Connect/Wireless Display app on the Windows PC.
- Open the screen mirroring feature on the Android device.
- Select your Windows PC from the device list.
- Confirm the pairing request in Windows.
Some modern Android devices support Google Cast but not Miracast. If your phone cannot see the PC, the phone may not support the required projection standard even though it can cast to a Chromecast or smart TV.
How to Fix Connect App and Miracast Problems in Windows
If the Connect app is missing, the PC is not discoverable, or wireless projection fails, work through the fixes below in order.
1. Make Sure Wireless Display Is Installed
Open Settings → Optional features and check the installed features list. If Wireless Display is missing, install it again.
2. Check Miracast Compatibility
Run dxdiag and verify that Miracast is available. If it is not supported, the Connect app may install but projection will not work reliably.
3. Update Wi-Fi and Graphics Drivers
Install the latest drivers from the PC manufacturer, motherboard manufacturer, graphics card vendor, or Wi-Fi adapter vendor. Avoid relying only on old generic drivers if wireless display stopped working after a Windows reinstall.
4. Turn Wi-Fi On
Miracast requires Wi-Fi functionality. Even if the receiving PC uses Ethernet for internet access, Wi-Fi must usually remain enabled for wireless display discovery and pairing.
5. Allow Wireless Display Through Windows Firewall
- Open Start and search for Allow an app through Windows Firewall.
- Click Change settings.
- Find Wireless Display.
- Allow it on the appropriate network types, preferably trusted private networks.
6. Remove and Reconnect the Wireless Display
On the sending device, remove the saved wireless display from Bluetooth or device settings, restart both devices, and pair again.
7. Check Network Profile and VPN Software
VPN clients, strict firewall suites, hotspot utilities, and public network profiles can interfere with discovery. Temporarily disable third-party network filters and test on a private network.
8. Restart the Wireless Display Feature
If the feature appears broken after an upgrade, remove Wireless Display from Optional features, restart Windows, install it again, then restart once more.
Best Use Cases
- Projecting from a laptop to another Windows PC
- Showing a phone screen during a demonstration
- Using a spare laptop as a temporary second display
- Testing Miracast support without extra hardware
Common Limitations
- Latency is higher than with an HDMI cable
- Gaming and fast video may feel delayed
- Some phones support Chromecast but not Miracast
