A recent innovation called screen mirroring (also known as miracast) enables a quick, lag-free connection between a sending device and a display receiver. As long as the two devices are linked to the same router, screen mirroring is typically pretty simple to accomplish. However, because of the nature of the technology, many users continue to have trouble getting their monitors to receive the proper visual signal.
Screen mirroring difficulties with the sender and receiver’s connections, Bluetooth interference, and active restriction settings are some of the causes of sound working but no picture when one or more devices are being used. In this thorough guide, I’ll walk you through a thorough troubleshooting procedure to assist you in identifying the cause of your screen mirroring’s lack of a picture. Then I’ll get into some of the quick, simple adjustments that can quickly and easily help you deliver a clear visual signal from one device to another.

1. Your Devices Aren’t Updated
One or more of your devices may not be updated, which is the most frequent cause of screen mirroring problems. It’s likely that the performance of your sender (a smartphone, tablet, laptop, etc.) and receiver (a monitor, projector, TV, etc.) will be subpar if they aren’t both using the most recent software available from their respective manufacturers. Therefore, I’d suggest initially checking the status of your devices’ software updates before delving into more complicated problems. In addition to the fact that this is the simplest problem to resolve, doing so can spare you from a drawn-out, tiresome debugging process.
How to Fix
Software updates for your devices are the first and simplest solution. Your transmitter and receiver must be using the most recent versions of the manufacturer’s software in order to establish a connection. To see if there are any outstanding updates, check the settings on each device.
2. Your Devices Aren’t Communicating With Each Other
As previously stated, a strong, stable connection between the transmitter and the receiver is necessary for the screen mirroring procedure to work. Because of this, it’s crucial to confirm that the two’s communication route is in good functioning order. You must make sure that all involved connectors are performing at their highest level of efficiency in order to establish stable communication between two devices.
This entails testing the functionality of your USB cable, router, and outlet. Each of these elements is essential to the signal’s transmission from one device to another. It’s possible that the image won’t ever reach its destination if one of them is broken.
How to Fix
To start with, you should rule out a router issue. You may check your connection’s speed by running a speed test using your WiFi connection and then another while using an ethernet wire. If the speed of WiFi and Ethernet varies significantly, your router may be slowing down your connection. An obsolete or faulty router is typically the blame in these situations. If your router is operating normally, you should check the locations of your devices.
It’s critical that the devices are close enough to one another and the network they’re linked to because the screen mirroring procedure depends on a strong, reliable connection. This will guarantee that the signal may pass through them without interruption.Move the transmitter device so that it is nearer the receiver. Try to move the router closer—ideally, to the same room—if it is far away from both. Make sure there are no large obstructions that can prevent the sender and receiver from transmitting a signal.
3. Bluetooth Is Interfering
The screen mirroring procedure relies heavily on a good WiFi connection. The signal you’re attempting to send through your router, though, can be hampered if Bluetooth is enabled on any of your devices.
How to Fix
Turn off Bluetooth connectivity in both the sender and the receiver to solve this problem quickly. Then, check to see if the problem has been resolved. Many people have been successful in screen mirroring while using their Bluetooth, so Bluetooth isn’t necessarily the issue. However, it can occur more frequently than you might imagine.
4. Restrictions Are Turned On
One of the hardest problems to identify is this one. There are situations when a device has default settings that prevent the screen mirroring signal from being broadcast or received; these restrictions may not even be known to you.
How to Fix
It could be a good idea to see if any of your devices demands the entry of a password before the connection is formed. If so, you should access that device’s settings and modify its connectivity limitations.
5. Your Devices are Not Compatible
A wide range of gadgets may now function as both senders and receivers thanks to technology. Your chosen equipment, however, might occasionally be incompatible with one another. For instance, it could be difficult to link an Android and iPhone device.
How to Fix
If your devices don’t work together, you might want to consider using a third-party mirroring programme. For instance, practically every operating system and browser are compatible with the Screen Mirroring App. Of course, you can always try a different device as a sender if you have the choice.
6. There’s a Software Glitch
Sometimes the gadgets themselves—rather than the connection—are the real problem. Given that the audio signal is functioning properly, a software error could be the cause of the visual signal’s failure to follow.
How to Fix
Turning both devices off, letting them a few minutes to cool off, and then turning them back on will quickly fix this problem. The majority of bugs will disappear following a restart. Try reinstalling the third-party software on both devices if the issue continues and you’re using one.
Final Thoughts
There are a number of issues that can prevent your screen mirroring from displaying any images. Fortunately, the majority of these are simple to fix. Screen mirroring (also known as Miracast) is a relatively new technology that enables a quick, lag-free connection between a sending device and a display receiver. If you find that you are still unable to resolve your issue after using this troubleshooting guide, don’t hesitate to contact a professional who can offer you technical expertise. As long as the two devices are linked to the same router, screen mirroring is typically pretty simple to accomplish.
