Android devices are great, but their small size can sometimes be limiting. When you connect your device to a projector, you can share your screen with others for business or pleasure. Here are some ways to do it.
If you don’t have a projector, you can also connect Android to a TV. Projectors are the best option, since they normally project a screen size much larger than a TV, making them ideal for multimedia playback or data presentations.
Connect wirelessly via Chromecast
The easiest way to connect an Android device to a projector is to use Google Chromecast. To do this, your projector must support HDMI connections.
Once you’ve plugged your Chromecast into the HDMI port, you can then wirelessly stream your Android device’s screen there. Your Chromecast will then display content through the projector.
Make sure you’ve turned off any power saving mode on your Android device, as this can reduce the quality of the stream.
If you don’t already have the Google Home app, download and install it from the Google Play Store.
Open the “Home” application, then tap the Accounts tab in the lower right corner.
Scroll down and tap “Mirror device”
If you see a warning that your device is not optimized for broadcast, press “OK”. That shouldn’t stop you from casting your screen to a Chromecast.
Tap “Cast screen / audio” and then select your Chromecast to connect to it.
Once connected, your screen should start streaming to your projector via your Chromecast.
If a wireless option is not suitable, you can use a wired connection instead. All Android devices come with a microUSB or USB-C option.
With the right cable, you can connect your Android device to a projector that directly uses an HDMI cable. Another supported standard is MHL, which also connects via HDMI ports.
USB-C to HDMI cable
New Android devices, like the latest Samsung phones, use USB-C to charge. If you have a USB-C device, you can use a USB-C to HDMI cable to connect your device directly to an HDMI compatible projector.
You should do nothing but connect your USB-C device to your projector. Make sure the projector is set to the correct HDMI input.
Be aware, however, that a drawback of USB-C to HDMI is the lack of power. If you use other wired methods, such as MHL, you can power your device when connected.
High Definition Mobile Link (MHL)
Mobile High-Definition Link (MHL) uses specially designed HDMI cables. Unlike the new USB-C method, MHL cables use microUSB. As mentioned above, it can also power your device while providing digital video and audio.
Some projectors support HDMI, but you will need to specifically search for an HDMI port with MHL label on your projector. If you don’t see it, it won’t power your device. Your Android device must also support MHL.
To connect via MHL, you should not do anything on your Android device, other than connecting it to your projector with an appropriate cable. On your projector, switch the input to the corresponding MHL HDMI port to see your projected Android screen.
Miracast and Wi-Fi Direct are wireless standards that connect devices to other devices like screens. Previously, Android officially supported Miracast, but dropped it with Android 6 Marshmallow. Miracast still works with some Android devices because it is based on Wi-Fi Direct, which is still supported by Android.
Unless both devices specifically state that they support Wi-Fi Direct or Miracast, the best way to see if it will connect is to use one of these standards to try it out.
To get started, on your projector, search for “Screen Mirroring”, “Device Mirroring” or a setting of the same name, and then switch to this mode.
The best way to connect using Miracast is to use a third-party application, such as CastTo, to make the connection. Since it is no longer officially supported, using Miracast with modern Android devices is not guaranteed to work.
If so, use a Chromecast, wired connection, or try using Wi-Fi Direct.
If you want to use Wi-Fi Direct, you can do so directly in Android. These steps may vary slightly depending on your version of Android and your device.
You need a projector that supports Wi-Fi Direct and allows you to broadcast your screen using this method.
To get started, swipe down on your screen to access your notification shade, and then tap the gear icon to access your Android “Settings” menu. Alternatively, you can access your “Settings” menu from the applications drawer.
If you are on a Samsung device, press “Connections”. On other Android devices, you may need to tap “Network and Internet” instead.
Press “Wi-Fi” to access the Wi-Fi menu.
In the Wi-Fi menu, make sure the setting is enabled, then tap “Wi-Fi Direct”. On other Android devices, you may need to first press “Advanced” or “Wi-Fi Preferences” in this menu, and then press “Wi-Fi Direct” to access this menu.
Your device will automatically search for available Wi-Fi Direct devices. If it locates your projector, tap the connection option, and then follow the instructions.
Smart View on Samsung devices
If you have a Samsung device, you can use Smart View to connect to certain wireless devices. Swipe down the shade of your notifications and tap “Smart View” in your quick actions list.
Your device will search for nearby Chromecast or Miracast devices. Locate your device, then tap it to connect. Your Samsung device should connect to your projector and start broadcasting there.
Some projector manufacturers offer their own Android apps that allow you to connect directly to the projector from your device via Wi-Fi.
These applications may not allow you to project your entire screen, but they should allow you to project static images or document files on your projector. While this is not a useful method for broadcasting media, it could be useful for professional presentations.
