My Windows 11 Lenovo laptop will not cast to Samsung TV

Hey Stephen, My name is Pau, and I'm an independent advisor. I get that this can be really frustrating, and I appreciate the clear information you shared. It really helps in figuring out this issue completely.

Considering what you've described and the troubleshooting steps you've already taken, here are all the possible solutions and checks to fix the Miracast connection issue with your Lenovo Ideapad Slim 5:

Make sure that your laptop and TV are compatible with the same version of the Miracast protocol.

Temporarily turn off any VPN or firewall on your laptop to check for interference.

On your laptop, navigate to Settings, then System, followed by Display, and finally Multiple displays. Choose your Samsung TV and click on Connect manually to try the connection again.

Open Device Manager, then go to Network adapters. Right-click on your WiFi adapter and select Properties. Next, navigate to the Power Management tab and uncheck the option that says "Allow the computer to turn off this device to save power."

In Device Manager, go to Display adapters. Reinstall your graphics driver by visiting Lenovo’s official support website. Make sure to choose the correct model and operating system version.

To run the Windows Troubleshooter, go to Settings, then Update & Security. From there, select Troubleshoot, followed by Additional troubleshooters. Finally, choose the option to find and fix problems with devices.

Check your Samsung TV to ensure that the screen mirroring or wireless display feature is turned on and not limited by any settings or parental controls.

Restart both devices after every step to ensure changes are applied.

If the issue continues, attempt to remove the TV from the list of devices paired with your laptop: Go to Settings, then Bluetooth & devices. Next, click on Devices, select the TV, and choose Remove device.

Next, attempt to add or connect the TV again using Project or Connect (Win + K).

Check if the Intel Graphics Command Center or AMD Radeon Software (based on your laptop’s GPU) has any wireless display settings that might need to be adjusted.

Temporarily turn off any third-party security or antivirus software on your laptop.

Make sure your WiFi router settings permit device-to-device communication and that “AP isolation” is turned off.

Test casting by using a Windows user account that has been created as a new profile to eliminate the possibility of user profile corruption.

If none of the above works, you can try a clean Windows reset by going to Settings, then System, then Recovery, and selecting Reset this PC as a last resort.

Kindly follow these steps and inform me of the result.

Thanks for waiting.

Kind regards,

Pau

I was facing the same problem with my Lenovo Ideapad Flex 5. I googled for the solution and ended up with your solution. I just followed the first step and it worked like charm! Thanks a bunch!

I have this problem also. Except for us, every computer and various different TV brands, including Samsung, Roku, Hisense. All worked a week and a half ago.

We can cast Tabs and they will stay up all day. When we try to cast Screens, they connect and display for about 10 seconds then drop. This happens on my work network and my home network in exactly the same way.

The only common thread is Windows.

We run automatic updates, so machines are current.

Casting is there but it no longer works like it used to two weeks ago.
