For the first time, the function of using a computer or laptop with Windows 10 as a wireless monitor (that is, to transmit images via Wi-Fi) for an Android phone / tablet or other Windows device appeared in version 1607 in 2016 in the form of the “Connect” application . In the current version 1809 (autumn 2018), this functionality is more integrated into the system (the corresponding sections in the parameters have appeared, buttons in the notification center), but it remains in the beta version.
In this manual, details about the possibilities of broadcasting to a computer in Windows 10 in the current implementation, about how to transfer an image to a computer from an Android phone or from another computer / laptop, and about the limitations and problems that you may encounter. It may also be interesting in the context: Broadcasting an image from Android to a computer with the ability to control it in ApowerMirror , How to connect a laptop to a TV via Wi-Fi to transfer images , How to transfer an image from iPhone to computer .
The main requirement for you to be able to use this opportunity: the presence of the included Wi-Fi adapter on all connected devices, it is also desirable that they are modern. Connection does not require all devices to be connected to the same Wi-Fi router, its presence is also not required: a direct connection is established between them.
Configuring the ability to transfer images to a computer or laptop with Windows 10
In order to enable the use of a computer with Windows 10 as a wireless monitor for other devices, you can perform some settings (you may not do it, which will also be mentioned later):
- Go to Start - Settings - System - Projection on this computer.
- Indicate when image projection is possible - “Available everywhere” or “Available everywhere on secure networks”. In my case, the successful operation of the function occurred only if the first item was selected: it was still not completely clear to me what is meant by secure networks (but it's not about the private / public network profile and Wi-Fi network security).
- Additionally, you can configure the parameters of the connection request (displayed on the device to which they are connecting) and the pin code (the request is displayed on the device from which the connection is made, and the pin code itself - on the device to which they are connected).
If in the settings window “Projection onto this computer” you see the text “There may be problems displaying content on this device, since its hardware was not specially designed for wireless projection,” this usually indicates one of:
- The installed Wi-Fi adapter does not support Miracast technology or does not do what Windows 10 expects (on some older laptops or PCs with Wi-Fi).
- The correct drivers for the wireless adapter are not installed (I recommend manually installing them from the website of the manufacturer of the laptop, monoblock, or, if it is a PC with a manually installed Wi-Fi adapter, from the site of the manufacturer of this adapter).
Interestingly, even in the absence of the Wi-Fi adapter declared by the manufacturer of the Miracast support, the built-in functions of Windows 10 image translation can sometimes work properly: some additional mechanisms may be involved.
As noted above, these settings can not be changed: if you leave the option “Always off” in the projection settings on the computer, but you need to start the broadcast once, just launch the built-in “Connect” application (can be found in the search on the taskbar or in the menu Start), and then, from another device, connect by following the instructions in the “Connect” application in Windows 10 or the steps described below.
Connect to Windows 10 as a wireless monitor
You can transfer the image to a computer or laptop with Windows 10 from another similar device (including Windows 8.1) or from an Android phone / tablet.
To broadcast from Android, it is usually enough to follow these steps:
- If Wi-Fi is turned off on the phone (tablet), turn it on.
- Open the notification curtain, and then “pull” it again to open the quick action buttons.
- Press the “Broadcast” button or, for Samsung Galaxy phones, “Smart View” (on Galaxy, you may also need to scroll the quick action buttons to the right if they occupy two screens).
- Wait for a while until the name of your computer appears in the list, click on it.
- If connection requests or a PIN code are included in the projection settings, give the appropriate permission on the computer to which you are connecting or provide a PIN code.
- Wait for the connection - the image from your Android will be displayed on the computer.
Here you may encounter the following nuances:
- If the “Broadcast” or similar item is missing from the buttons, try the steps from the first part of the Transferring an Image from Android to TV instruction. Perhaps the option is still somewhere in the parameters of your smartphone (you can try using the search by settings).
- If on “pure” Android after pressing the broadcast button the available devices are not displayed, try clicking “Settings” - in the next window they can be initialized without any problems (seen on Android 6 and 7).
To connect from another device with Windows 10, several methods are possible, the simplest of which:
- Press Win + P (Latin) on the keyboard of the computer from which you are connecting. The second option: click the "Connect" or "Transfer to screen" button in the notification center (previously, if you only have 4 buttons, click "Expand").
- In the menu that opens on the right, select "Connect to a wireless display." If the item does not appear, your Wi-Fi adapter or its driver does not support the function.
- When the computer to which we are connecting appears in the list, click on it and wait for the connection to be completed, you may need to confirm the connection on the computer to which we are connecting. After that, the broadcast will begin.
- When broadcasting between Windows 10 computers and laptops, you can also choose an optimized connection mode for different types of content - watching videos, working or playing games (however, most likely it will not work, except in board games - the speed is insufficient).
If something fails while connecting, pay attention to the last section of the manual, some observations from it may be useful.
Touch input when connected to a Windows 10 wireless display
If you started transferring images to your computer from another device, it would be logical to want to control this device on this computer. It is possible, but not always:
- Apparently, the function is not supported for Android devices (tested with different equipment on both sides). In previous versions of Windows, it reported that touch input is not supported on this device, it now reports in English: To enable input, go to your PC and select Action Center - Connect - select the Allow input checkbox (check "Allow input" in the notification center on the computer from which the connection is made). However, there is no such mark.
- The indicated mark in my experiments appears only when connecting between two computers with Windows 10 (we go on the computer from which we connect to the notification center - connect - we see the connected device and the mark), but only on the condition that the device to which we connect is problem free Wi -Fi adapter with full Miracast support. Interestingly, in my test, touch input works even if you do not enable this mark.
- At the same time, for some Android phones (for example, Samsung Galaxy Note 9 with Android 8.1), input from the computer keyboard is automatically available during broadcasting (although you have to select the input field on the screen of the phone itself).
As a result, full-fledged work with input can be achieved only on two computers or laptops, provided that their configuration will completely "suit" the broadcast functions of Windows 10.
Note: for touch input during translation, the “Touch Keyboard and Handwriting Panel Service” is activated, it must be enabled: if you disabled “unnecessary” services, check.
Current Issues When Using Image Transfer on Windows 10
In addition to the already mentioned problems with the ability to enter, during the tests I noticed the following nuances:
- Sometimes the first connection works fine, then, after disconnecting, the second one becomes impossible: the wireless monitor is not displayed and is not searched. It helps: sometimes - manually launching the “Connect” application or disabling the broadcast option in the settings and re-enabling it. Sometimes it’s just a reboot. Well, be sure to make sure that both devices have Wi-Fi enabled.
- If the connection cannot be established in any way (there is no connection, the wireless monitor is not visible), it is more likely that the case is in the Wi-Fi adapter: moreover, judging by the reviews, this sometimes happens for fully compatible Miracast Wi-Fi adapters with original drivers . In any case, try manually installing the original drivers provided by the hardware manufacturer.
As a result: the function works, but not always and not for all use cases. Nevertheless, to be aware of such an opportunity, I think it will be useful. To write the material used devices:
- PC Windows 10 1809 Pro, i7-4770, Wi-Fi TP-Link adapter on Atheros AR9287
- Notebook Dell Vostro 5568, Windows 10 Pro, i5-7250, Wi-Fi adapter Intel AC3165
- Smartphones Moto X Play (Android 7.1.1) and Samsung Galaxy Note 9 (Android 8.1)
Image transfer worked in all cases, both between computers and from two phones, but full input was possible only when broadcasting from a PC to a laptop.
