Why is Screen Mirroring Not Working on My Samsung TV? + How to Fix

Screen mirroring lets you broadcast pictures, movies, and other digital materials wirelessly from your smartphone or computer to your smart TV. Basically, it allows you to mirror your smartphone’s screen onto your Samsung TV.

However, there are times when screen mirroring fails to work properly. In this article, our technicians listed the possible reasons why screen mirroring won’t work on a Samsung TV.

How to Fix Screen Mirroring Issues on a Samsung TV

Fix #1: Check Your Network Connection

You may be unaware that Samsung TV screen mirroring necessitates being on the same Wi-Fi network. It works by sending the signal from your device to the TV via your home Wi-Fi.

If you’re having trouble connecting to Wi-Fi, you may need to restart the modem and router. Here’s how:

checking router connections

Fix #2: Move the TV and Device Closer

Another potential screen mirroring solution is to move your device closer to your Samsung Smart TV. Even though a Wi-Fi connection is long-range, you may be restricted if you are near the perimeter of that range in your home network.

Fix #3: Remove Any Obstructions

Screen mirroring works with wireless technology. So, any obstacle between Samsung TV and your device can disrupt signal transmission. 

Thus, before connecting devices, remove any physical obstructions.

Fix #4: Check if They are Compatible

If the screen mirroring option is not working on your Samsung TV, check both the TV and device’s compatibility. Screen casting compatibility varies between mobile devices and televisions.

Some old Samsung TV units cannot screencast directly. However, you can connect them using other devices, such as a Chromecast device to screencast from compatible mobile devices to your TV. Chromecast should work as long as you have a Wi-Fi connection.

You should also check your smartphone’s screen compatibility with screen mirroring. Screen mirroring is not supported by all smart devices. 

Furthermore, not all devices are compatible with Smart TVs. To enjoy screen mirroring between your Samsung TV and mobile device, ensure they can support this feature.

Fix #5: Use Another Device

This time, you can try connecting to another device to diagnose the problem, whether with the TV or the mobile device. 

If the second phone begins screen mirroring, there is a problem with the previous phone. If the problem persists, proceed with the following fixes. 

Fix #6: Temporarily Disable Bluetooth

As mentioned above, screen mirroring working on a Samsung TV requires a WiFi connection, not Bluetooth. 

Bluetooth turned off

If you’re having trouble screen mirroring your Samsung television or connecting from your Samsung TV to another device, we suggest disabling Bluetooth in your Samsung TV’s settings menu. This may help you get your screencast working again.

Fix #7: Restart Your Samsung TV

As this is a common problem in Samsung TVs, restarting your Samsung Smart TV may resolve the screen mirroring problem. 

  1. Hold the standby button on your Samsung TV remote control.
  2. Wait for a while until your Samsung TV screen turns black. 
  3. Finally, press the power button or the standby button again. 

After that, see if the screen mirroring is now working on your Samsung TV.

Fix #8: Restart Your Device

If restarting your Samsung TV didn’t fix the screen mirroring problem, we suggest a restart of your gadget or mobile device. Here’s how to do it:

Power Button of Samsung TV
  1. Hold down the power button. 
  2. Then, a small screen will display on your Samsung TV screen. 
  3. From there, tap the reboot or restart option. 

Fix #9: Check for Software Updates

You need to verify if both your TV and android device (or iOS device) has the most recent software. You can start by updating your device and Samsung TV’s software.

Fix #10: Reset the TV Using the Remote

You can do a hard reset using your original Samsung TV’s remote control. Refer to the following steps:

This reset clears the memory cache, leaving you with a clean memory. This not fixes screen mirroring issues on your Samsung TV but also makes your Samsung TV run smoothly. 

Fix #11: Reset the TV Using the TV Buttons

If you don’t have your Samsung Smart TV remote, you can still do the reset using the TV buttons. Just follow these steps: 

  1. Ensure your Samsung Smart TV is turned on. 
  2. Unplug your TV (or detach it from the receptacle or power strip) to shut down your TV. (Note: Having your TV turned on during this step is part of the process.)
  3. While unplugged, wait 30 seconds before plugging it back into the power supply.
  4. Then, turn on the TV by pressing its power button until the screen goes on.

You’re cold booting the TV while discharging all residual power during this process. It clears the memory cache, and you’ll notice that your TV runs more smoothly. It will also usually resolve issues with screen mirroring.

Alternative: Use a Third-Party App

If screen mirroring still isn’t working on your Samsung TV, you can use your mobile device to connec to the TV with any third-party app. 

Third-party apps allow you to easily mirror any device to your Samsung TV or most Smart TVs. Smooth screen mirroring working on Samsung TV is possible using an external device manager like Chromecast or AirDroid Cast.
