Screen mirroring is not as streamlined as we think, it is because various factors are involved. Many people think that this system is not perfect, but that is not the case. If you know the problem, you can solve it in advance. When your screen mirroring system doesn’t work, you can use various techniques to solve the issue.
Many people find it difficult to organize this system, and they consider it to be a hit and miss technology. They do not know that they can take various measures to stop their screen mirror system from working as you want. If you have limited knowledge about screen mirroring, you’re likely to run into problems.
With screen mirror technology, you can easily switch from the media that is playing on your Apple, Windows, or Android devices on a large screen such as media projector, television, etc. You can mirror your games, videos, music, personal photos, and much more. You can also view applications that run through the internet, such as YouTube and Netflix.
Laptops have more than one display mode while mirroring. Usually, you will encounter four types of displays.
1.External display only
2.Laptop display only
3.Extending the laptop display on your external display.
4.Duplicating the display of a laptop on an external display.
Sometimes, when you connect your device to a projector for external display, you will not be able to see the display. This usually happens when you incorrectly select the mode of display. Presenters usually use two types of displays. Some presenters are comfortable in using extended display, in which you need to set the presenter view options to this model. Some presenters use duplicate display, which displays the same content on the projector and the laptop.
In the presenter's view, you will be able to view upcoming slides, the current slide, and notes. Meanwhile, in an external display, you will be showing slides. This mode sounds amazing, but it depends on the projector and the computer’s capabilities. Also, many presenters are unable to control this feature. Experts don’t recommend this mode as it may sometimes cause confusion, and you may think that the screen isn’t mirroring. Many laptops are set to extended display mode on default when you connect your projector to your laptop, but you may feel like screen mirroring is not working.
To solve this problem, you need to switch your display mode. For that, you need to press Windows + P in Windows 8 or 10 (simply hold the Windows button and press P). Now, a screen will appear, showing you all the display modes.
You can shift through modes using the arrow keys. On many laptops, you can rotate between modes using key combinations. For instance, if you are using Windows 7, you can shift through the display mode with this method. Various computers have a dedicated key to switch to display mode. Make sure that you are pressing the function key along with the display mode key. After you press the key, you need to wait a few seconds for the setting to appear.
For the longest time, presenters relied on a VGA cable connection in their laptops, but they have now shifted to HDMI for screen mirroring. Nonetheless, many projectors are still using both VGA and HDMI cables to mirror the screen from your device to the projector and display the mirrored screen on the wall or white screen. There is a connector on both ends, which has 15 pins. You can use it to connect your devices to the projector. If your projector has an HDMI connection, we recommend you to connect your system with this cable for greater compatibility.
While connecting your data projector to your computer, you may experience a loose cable problem sometimes.
You need to connect all your cables securely in their suitable ports as many laptops require dongles to convert between VGA or HDMI and a USB-C or DisplayPort cable. Hence, carefully check each cable connection. You should remove all cables and re-seat them to make sure that the cables have proper connections.
Some projectors may have multiple input sources. It’s possible that the selected input source on the projector is using an input source that’s different from what your laptop is connected to.
On top of your projector, you can see a button. If it is not on the top, it may be on the sides of your projector. This button allows you to toggle through different input sources. If you cannot find the button on your projector, you can also change your laptop’s input source so that both devices are using the same input source. If you have an older projector, there may not be a button to toggle through the input sources. To change the input source on an old projector, you need to go through the settings and search for the option. Simply change the input source, and you can enable screen mirroring.
Forgetting to turn on the power is another reason why your projector may not be displaying the screen. This is also a common problem.
This problem occurs because when we turn on our laptop, you may not have connected it to a charger, making it run on battery. We forget and do not realize that our projector is not connected to a power source. Hence, when we try to turn on the projector, nothing will happen.
You need to check if you plugged in the power cord correctly or not. If it isn’t connected properly, make sure to plug it into a suitable power outlet. It’s likely that you have plugged in the power cord but forgotten to turn on the switch.
If you cannot find any of the above issues, this may be the problem. If you have connected your computer to the projector, but the display is not available, check if the projector is on the standby mode.
When your projector is on standby mode, the fan of the projector will keep on running, but the bulb will turn off. Standby mode is to cool down the projector after you are done with the presentation.
To solve this problem, you need to press the button to turn it on, and the projector will start running normally.
When you usually move or transfer your data projector, the cover of your projector may sometimes get loose. When this happens, even if you have plugged in the cord and turned on the switch, your projector will not work. Even if the projector is powered on, the bulb will not turn on due to safety reasons.
To solve this problem, you need to check all the covers to see if it is properly connected or not. If the covers don’t fit properly, you need to fix them, so they are no longer loose. Always remember, never check if your covers are loose or not while the projector is on. You may burn a component inside your projector or will be at risk of electrocution.
If your projector detects any problems, it automatically turns off. If you are experiencing a similar issue, the problem is not about your screen mirroring, but there may be two possibilities. Either the filters or fans are dirty, or the generic lamp is not working
To solve this problem, you need to open your projector’s case and clean out the dirt and dust with a blower. This will allow the components of your projector to work again. If you have cleaned the projector and it is still not working, then dirt may not be the problem.
Another reason for this problem will be the lamp. If you recently changed the projector’s lamp, you need to check if the lamp is suitable for your projector model or not. Generic lamps aren’t compatible with all projector models. Installing such lamps will cause an imbalance in the system, and your projector will shutdown. The only solution to this problem is to replace the lamp with an original one that suits your projector model.
By following the above methods and techniques to solve the issue of screen mirroring, you can solve the problem. If the projector is still not working, you need to take the projector to an expert. Proper maintenance of your projector is important as you can get into trouble if you want to use the projector, and it fails to work.
