Screen mirroring, which is also called Miracast, is a cutting-edge way to send content from one device to another without wires.
Screen mirroring is usually easy to do, as long as both devices are connected to the same router.
However, because of the technology’s limitations, many users still experience difficulties in getting the intended visual signal to their monitors.
Screen mirroring sounds but not images can happen if the hardware isn’t up to date, there are connection problems between the transmitter and the receiver, Bluetooth interferes, or the restriction settings are turned on.
Here I’ll walk you through a full troubleshooting approach to help you determine what’s causing your screen mirroring to be blank.
Then, I’ll talk about a few simple ways to improve the quality of the visual signal sent from one device to another that can be done quickly and effectively.
1. 1. Your Devices Aren’t Updated
2. 2. Your Devices Aren’t Communicating With Each Other
3. 3. Bluetooth Is Interfering
4. 4. Restrictions Are Turned On
5. 5. Your Devices are Not Compatible
6. 6. There’s a Software Glitch
1. Your Devices Aren’t Updated
Problems with screen mirroring typically occur when one or more of your devices aren’t up to date.
Your transmission speed and reception quality will be affected if the software on both your sending device (smartphone, tablet, laptop, etc.) and your receiving device (monitor, projector, TV, etc.) is not the most recent version available from its maker.
So, before looking into more complicated problems, I would check to see if your devices have the latest software updates.
It’s the simplest problem to solve, and fixing it might save you hours of frustration if you haven’t already.
How to Fix
One of the quickest and easiest solutions is to just update the software on your gadgets. In order for your transmitter and receiver to establish a connection, it is essential that they both use the most up-to-date software released by the manufacturer.
Check the settings of the device to see if there are any updates that need to be installed.
2. Your Devices Aren’t Communicating With Each Other
As was already said, screen mirroring needs a connection between the transmitter and the receiver that is always on and works well.
Because of this, it is very important to make sure that they can talk to each other.
You need to make sure that all the connectors between the devices are functioning at peak efficiency if you want to establish reliable communication between them.
This includes making sure your USB cord, wireless router, and wall outlet are all functioning properly.
Each of these parts is critical to the successful transmission of the signal from one gadget to another.
There is a risk that the image will never reach its intended recipient if any of the links in the chain are broken.
How to Fix
You should check your router first to make sure it isn’t malfunctioning.
To achieve this, run a speed test over your WiFi connection and then run another test while hardwired into your computer.
If you notice a significant speed difference between WiFi and Ethernet, your router may be limiting your bandwidth.
An old or broken router is generally to blame in these situations.
Check the placement of your gadgets if your network is functioning properly.
Due to the need for a solid connection for the screen mirroring procedure, it is essential that the devices be in close proximity to one another and the router.
This will ensure that the signal can pass through them without any disruptions.
You can try getting the sending device closer to the receiving one.
It would be great if the router were in the same room as the computer and the TV, so try moving it if necessary.
Check to see if there are any big things between the sender and the receiver that could mess up the signal.
There comes a time when you have to really stop and think. Is my internet connection acting up again? Is this a new problem? In fact, I have a hard time maintaining a stable connection on any of my electronic devices, including my phone, laptop, and games. now, with my screen-sharing software.
Similar issues with other wireless gadgets in the house suggest upgrading the router.
3. Bluetooth Is Interfering
If you want to mirror your screen, you’ll need a reliable WiFi connection.
However, if you have Bluetooth turned on on any of your devices, it may be interfering with the signal you are trying to send through your router.
How to Fix
To fix this problem, turn off Bluetooth on both the sending and receiving devices and see if things get better.
Many people have reported success with screen mirroring while also making use of their Bluetooth, so this may not always be the case.
Even so, it’s not as uncommon as you may expect.
4. Restrictions Are Turned On
This is a difficult problem to diagnose.
If the device is set up in a certain way, the screen-mirroring signal might not be sent or received. You might not even know this.
How to Fix
here to Find a Solution
Before you establish a connection, it’s a good idea to see if either of your gadgets needs a password.
If that’s the case, you can change the restrictions on the device’s internet access under its settings.
5. Your Devices are Not Compatible
Because technology has gotten better, more and more gadgets can now both send and receive signals.
However, there are times when the tools you’ve selected are incompatible.
For instance, it could be difficult to pair an Android and an iPhone.
How to Fix
Where to Find a Solution
You might want to try finding a mirroring app that works with your devices if you can’t find one that does.
The Screen Mirroring app, for instance, is accessible on nearly every operating system and browser.
Naturally, if you have the luxury of choice, you can also test a different device as the sender.
6. There’s a Software Glitch
It’s not always the connection that’s at fault, but rather the devices themselves.
The audio appears to be transmitting normally, so a software issue may be to blame for the video not following suit.
How to Fix
The problem can be quickly fixed by powering off both gadgets, waiting a minute or two for them to cool down, and then turning them back on.
Once you restart, most problems should be fixed.
If a third-party program is to blame, reinstalling it on both devices may solve the problem.
Final Thoughts
There are a few different issues that can prevent screen mirroring from working.
Fortunately, the vast majority of them have simple answers.
If you’ve gone through this troubleshooting tutorial and still aren’t able to resolve your issue, don’t be afraid to seek the help of a knowledgeable technical specialist.
Screen mirroring relies on a stable connection across devices, so it’s important to use a router with enough range to reach them all.
