Not all owners of modern Smart TV and Android smartphones or tablets know that it is possible to transfer images from a phone to a TV via Wi-Fi using Miracast technology. There are other ways, for example, using an MHL or Chromecast cable (a separate device that connects to the TV’s HDMI port and receives an image via Wi-Fi) or using DLNA when connected to the same network.
This guide details how to use the ability to broadcast images with sound from your Android phone 9, 8, 7 and earlier to a TV that supports Miracast technology (Screen Mirroring). At the same time, despite the fact that the connection is via Wi-FI, the presence of a home router is not required, in any case for direct transmission, which is discussed in the first part of the manual.

Checking screencast support on Android and enabling streaming
In order not to waste time, I recommend first to make sure that your phone or tablet supports displaying images on wireless displays: the fact is that not every Android device is capable of this - many of them related to the lower and partially to the middle price segment are not support Miracast.
- On Android 9 (in the case of a clean OS) go to Settings - Connected devices - Connection settings - Broadcast and make sure that the option to transfer images from your phone is enabled in the menu, as in the screenshot below.
- On Samsung Galaxy smartphones, open the notification area completely and see if there is a Smart View icon (note that the icons in the notification area can be scrolled and the desired one may not appear on the first page).
- On earlier versions of the OS, go to Settings - Screen and see if there is an item “Broadcast” (in Android 6 and 7) or “Wireless Display (Miracast)” (Android 5 and some devices with branded shells). If the item is present, you can immediately switch it to the “On” state using the menu (called up by three points) on pure Android or the On-off switch in some shells.
- Another location where you can detect the presence or absence of the wireless image transfer function (“Send Screen” or “Broadcast”) is the quick settings area in the Android notification area (however, it may be that the function is supported, but there is no button to enable broadcasting, or it is hidden and can be turned on in the settings, as shown in the video below).
If you didn’t find the parameters of the wireless display, Screen Mirroring, Smart View, Broadcast, Miracast or WiDi functions, try searching the settings by going to the settings and using the search field. If nothing of the kind is found - with a high probability, your device does not support the wireless transmission of images to a TV or other compatible screen.
How to enable Miracast (WiDI) image broadcast support on Samsung, LG, Sony and Philips TVs
Usually, in order to be able to transfer the image from the phone to the TV, it is enough for the TV to be turned on and the Wi-Fi adapter turned on, but sometimes the wireless display function is turned off on the TV and you may need to turn it on in the settings first. Below are examples of such settings, on your TV the items may vary slightly, but the logic is usually the same and you can find the necessary parameters.
- Samsung - on the TV remote control, press the Source button and select Screen Mirroring. Also, the network settings of some Samsung TVs may contain additional settings for mirroring the screen.
- LG - go to settings (Settings button on the remote) - Network - Miracast (Intel WiDi) and enable this function.
- Sony Bravia - press the source selection button on the TV remote control (usually top left) and select “Screen Duplication”. Also, if you turn on the Built-in Wi-Fi and a separate Wi-Fi Direct item in the TV’s network settings (go to Home, open Settings - Network there), the broadcast can be started without selecting a signal source (the TV will automatically switch to wireless broadcasting), but while the TV should already be turned on.
- Philips - the option is turned on in Settings - Network Settings - Wi-Fi Miracast.
Theoretically, the points may change from model to model, but almost all of today's TVs with a Wi-Fi module support image reception over Wi-Fi, and I'm sure you can find the right menu item.
Transferring images to an Android TV via Wi-Fi (Miracast)
Before you start, be sure to turn on Wi-Fi on your Android phone or tablet, otherwise the following steps will show that wireless screens are not available.
Slightly different actions may be required to transfer the image from the phone to the TV depending on the version of Android and the brand of the smartphone, but the following options are usually available:
- In the notification area, find the “Broadcast” icon, and after searching for available TVs, click on the desired one and wait for the broadcast to begin.
- If you have a Samsung Galaxy phone, in the notification area, find the Smart View icon, click on it, wait for the TV to be found, click on it and wait for the broadcast to start.
- Go to Settings - Screen - Broadcast (or Miracast Wireless Screen), your TV will be displayed in the list (it should be turned on at that moment). Click on it and wait until the connection is completed. On some TVs, you will need to “allow” to connect (a request appears on the TV screen).
- Open the quick action list in the Android notification area, select the “Broadcast” button (it may be absent), after finding your TV, click on it.
That's all - if everything went well, then after a short time you will see the screen of your smartphone or tablet on the TV (in the photo below, the Camera application is open on the device and the image is duplicated on TV).
You might also find the additional information useful:
- Connection is not always the first time (sometimes it tries to connect for a long time and nothing comes out), but if everything that is required is enabled and supported, you usually manage to achieve a positive result.
- The transmission speed of the image and sound may not be the best, so playing in most games will not work.
- If you run some kind of video on the phone, and it is transmitted to the TV as a black screen (which may be in some players and with protected content), it is better to use the transfer methods described later in the section with additional image transfer methods.
- If you usually use the portrait (vertical) orientation of the screen, then turning on the automatic rotation and turning the device, you will make the image occupy the entire screen of the TV.

Additional features for transferring images, videos and photos from Android to TV
If your task is to transfer videos and photos to a TV, and not just transfer the screen with all its limitations, I recommend using other methods, but keep in mind that, unlike the previous method, it requires that both the TV and smartphone are connected to the same Networks (via cable or Wi-Fi - does not matter):
I hope one of the proposed solutions turned out to be workable for your scenario of sharing a phone and a TV.
