Hello Abdul,
Thank you for posting in Microsoft Community.
I appreciate you raising this concern to us, and I understand that you're experiencing an issue with projecting display from your Surface. You got me here: we'll isolate this issue together. Allow me to ask this question:
- May I know what is the make and model of the TV?
- Does this work before?
Here are things you may try to fix the issue:
- Make sure that your Surface Pro 7 and your smart TV are connected to the same Wi-Fi network.
- Check if your smart TV supports Miracast. If it does, you can use these features to cast your Surface Pro 7 to your TV.
- On your Surface Pro 7, go to Settings > Devices > Bluetooth & other devices > Add Bluetooth or other device > Wireless display or dock. Your Surface Pro 7 should detect your smart TV. Select it and follow the on-screen instructions to connect.
If that doesn't work, try these:
- Try to reinstall the network adapter driver. Go to Device manager > expand Network Adapter > right click Intel R Wi-fi > select Uninstall > Restart device after.
- Allow the adapter to communicate through Windows Firewall
Windows Firewall might be preventing the adapter from connecting to your device. Here's how to allow the adapter to communicate through the firewall:
- Select **Search**on the taskbar, enter **allow firewall**, then select **Allow an app through Windows Firewall**from the list of results.
- Under **Name**, find **Wireless Display**, make sure **Private**and **Public** are selected, then select **OK**.
**Note:**If you can’t select anything in the Allowed apps and features box, you aren't logged in as an administrator. Select Change Settings, type your administrator password, and select Yes. If you're an administrator on your device, the password should be the same as the one you used to set up your device. Then, make sure Private and Public are selected and select OK.

Please let me know how it goes and hopefully it helps!
