Wirelessly Connect an Android Phone to a Projector
Using wireless streaming adapters and built-in projector mirroring support, you can get your Android device on the big screen. Typically, you need an app to get this working.
Chromecast
One of the easiest options for getting your Android phone or tablet connected to a projector wirelessly is through the use of a Chromecast streaming adapter. The small device plugs into any projector with an HDMI port and can be found at most electronic retailers for about $35. Chromecast is a powerful part of the Google ecosystem. Many applications, including Spotify and Netflix, feature one-click buttons for casting. Alternatively, you can cast your entire device’s screen using the Cast Screen button in the Android navigation menu.
Manufacturer Streaming
Your projector might have built-in smart capabilities. Companies such as Samsung, LG, and others include video-streaming support with their projectors and televisions. Look up the model number of your projector on the manufacturer’s website to see if streaming or wireless device mirroring support is available. If your projector allows you to connect devices such as your Android phone, check the Play Store for the necessary application. Different manufacturers handle streaming solutions in slightly different ways, but having a smart projector is a quick way to get set up for fast streaming.
Connect an Android Device to a Projector via Wire
Wirelessly connecting your Android phone or tablet to a projector isn’t always an option. You might not have access to a wireless network to facilitate the connection between the projector and your laptop, or you might want a quick plug-and-play solution with wires being of little concern.
HDMI
Most projectors have a built-in HDMI port for supporting a hard-wired video connection. Some Android phones have a Mini-HDMI port on their exterior, which you can use to connect to a projector with a Mini-HDMI to HDMI cable. Additionally, many USB-C devices, such as the Samsung Galaxy S9 and Note 9, can use a USB-C to HDMI adapter to support the connection. If your Android phone or tablet has a USB-C port, check with your manufacturer to see if the device supports using an adapter for HDMI video out.
MHL
The micro-USB port you use on your Android phone might be more powerful than you think. Some manufacturers have opted to support a new standard known as MHL; it allows video signals to be transmitted with a special adapter from a micro-USB port. If supported, you need to purchase an MHL to HDMI adapter for your device. Knowing which devices support MHL can be tricky at first glance, but thanks to the MHL website, you can view all devices that support the standard in one easy-to-view page. Unfortunately, recent phones appear to have dropped the standard in favor of using USB-C.
