Identify the destination and protocol
Microsoft’s external-display procedure is for a display that supports Miracast. A television supporting a different wireless protocol does not establish that this particular connection route is available. Record the receiving device’s stated protocol and the sending computer’s actual capabilities.
If another Windows PC is the destination, label it receiver in your notes and label the computer containing the presentation sender. A household can have two identical laptops, so use their recognisable device names as well. This avoids making a receiver setting change on the computer that was supposed to send.
Prepare a Windows receiver when that is the intended task
On the receiving Windows 11 PC, open Settings, System, Projecting to this PC. Use the offered optional-feature route, choose View features, search for Wireless Display and install the feature. Return to Projecting to this PC to configure its preferences, then launch the Wireless Display app.
Microsoft specifies that app for Windows 11 version 22H2 and later; its earlier-version instructions refer to the Connect app. Use the branch matching the receiver’s installed version. Finding a similarly named app on the sender is not confirmation that the receiving PC is listening.
Connect first, then select the desktop arrangement
On the sender, press Windows key plus K and select the intended ready display. Follow the destination’s on-screen instructions. Confirm the receiver’s identity before accepting a connection, especially when several names are visible.
Windows key plus P addresses the presentation arrangement, offering PC screen only, Duplicate, Extend and Second screen only. It is a separate decision from discovering and connecting to a receiver. For example, Extend can make a player remain on the laptop desktop until its window is moved; that observation is different from the destination never appearing in the connection list.
Describe the failed stage precisely
If a receiving PC is absent, Microsoft advises checking that Wi-Fi is on and the receiving app is installed and launched. Record those conditions, the Windows version and whether the name appeared. If connection succeeds but the intended window is missing, record the chosen projection mode and where the window remains.
No wireless connection was performed for this article. These documented steps do not certify protected-video playback or convert another casting protocol into Miracast. They produce a clearer support record by separating discovery, connection and desktop presentation.
