If you want the functions of your TCL Smart TV to run smoothly, you’ll need to ensure that you have a stable internet connection.

Various functions, such as the screen mirroring, will not work efficiently if your Wi-Fi has a poor signal or slow connection. 

Ensure to check the speed of your Wi-Fi if you are having serious problems with your screen mirroring function, and if your Wi-Fi has a poor connection, you could try connecting your Smart TV to your mobile hotspot. 

I also recommend resetting your router, even if your Wi-Fi signal seems fine:

1. Turn your router off.
2. Wait for 1-2 minutes.
3. Turn your router back on.
4. Wait for it to establish the internet connection.

Now try using the screen mirroring option and see if the reset has worked.

Tip: Please, make sure your TV and your source device are connected to the same Wi-Fi network.

2. Reset Your TCL Smart TV

The following fix is one of the most common ideas; however, from time to time, people forget this step.

You can simply restart your TCL Smart TV if you’re having a problem with the screen mirroring function, as this will give your TV a fresh start. 

1. Turn your TV off.
2. Unplug it from the power source.
3. Wait for 1 minute.
4. Plug the TV back in and turn it on.

Once the Smart TV has turned on, it may solve the error thanks to a reboot.

Typically, this can solve a handful of problems surrounding your TV, and it’s worth a try when trying to correct a screen mirroring problem. 

3. Reset Your Source Device

It always takes 2 to tango when it comes to screen mirroring, so it makes sense to reset your source device next.

This step depends on what kind of device you are using, but chances are, it will be either your smartphone or your laptop.

With your smartphone, simply power it off, then turn it back on after a minute or so.

With your laptop, press the restart button and wait for it to do its thing.

Tip: While you are at it, please, make sure your source device’s software is up-to-date and doesn’t require any updates. It’s always a good idea to clear the cache and cookies and get rid of any unused files.

4. Forget the Network

If you’ve tried the 3 steps we talked about before, here is one more thing I suggest you try.

Go to your TV’s settings and disconnect it from the internet altogether.

You can combine it with power cycling, as described is step 2.

Do exactly the same steps for your smartphone/laptop.

Disconnect them from the internet, turn them off, then back on.

Now establish a fresh connection between your TV and your source device.

I am sure that should help get rid of any software issues and finally get the screen mirroring to work.
