bilgisayardan tv ye yansıtma olmuyor

hi Murat, welcome in community

try these steps:

press Windows key + K on your computer. This opens the Cast panel in the lower-right corner of the screen, from here if your TV appears in the list, select it to start mirroring. If it does not show up, continue to the next step.

Step 1: Install the Wireless Display feature In Windows 11, wireless screen sharing may be treated as an optional component that is not installed by default. Open Settings, go to System, and then to Optional features. Select View features next to the option to add new features, search for Wireless Display, select it, and proceed with the installation. After the feature is installed, restart the computer and try the Windows key + K shortcut again.

Step 2: Verify Miracast compatibility Not all systems are capable of wireless display mirroring, so it is important to confirm hardware support. Press Windows key + R, type dxdiag, and press Enter. When the DirectX Diagnostic Tool opens, choose Save All Information and store the file on your desktop. Open the saved text file and search for the term “Miracast.”

If the result shows “Available, with HDCP,” your system supports wireless mirroring. If it reports “Not Supported,” the limitation is likely due to the Wi-Fi or graphics hardware, and using a wired HDMI connection may be necessary.

if you don't know how, share here the dxdiag log

Step 3: Drivers and firewall configuration If your hardware supports Miracast but the TV still cannot be detected, driver or firewall settings may be blocking the connection.

Start by updating your network drivers: right-click the Start button, open Device Manager, expand Network adapters, right-click your Wi-Fi adapter, and choose to update the driver automatically.

After that, check the Windows Firewall settings by searching for “Allow an app through Windows Firewall” in the Start menu. Open the settings with administrative privileges, locate Wireless Display and Connect in the list, and ensure they are allowed on both private and public networks. Confirm the changes and try connecting again.

let me know how it goes
