How to Connect an Android Phone to a Projector with USB

In the digital age, one of the most useful aspects of Android devices is their ability to share content on larger displays. This guide is aimed at helping you understand how to connect your Android phone to a projector using a USB or USB-C cable. Several methods are available, and the most suitable for you will depend on the type of connectivity your projector and phone offer.

Step 1: Understanding your Projector’s Connectivity Options

The first step in connecting your Android device to a projector with a USB or USB-C cable is to identify the types of connections your projector offers. Modern projectors often come equipped with an array of output options, ranging from HDMI ports and USB to VGA and on-board Bluetooth.

Using an HDMI Cable for Superior Quality

HDMI (High Definition Multimedia Interface) is arguably the best option for delivering superior picture and sound quality. This connection type is prevalent in most modern projectors and is ideal for connecting gaming systems (find our list of top gaming projectors here) or cable boxes.  However, it can be a bit more complex when dealing with Android devices, which typically only offer a single micro-USB or USB-C port.

Utilizing USB or USB-C Port

Newer projectors may feature a USB or USB-C port, which can make the connection process significantly more straightforward. If your projector has this option, all you need to do is connect a USB or USB-C cable to both your Android device and the projector. Ensure that your projector is set to the correct input channel before turning both devices on.

If your projector lacks a USB or USB-C port, assess the available connections. Even if there’s no USB, there should be at least one HDMI port which is the second-easiest method for a wired connection. If you’re dealing with an older projector that lacks HDMI ports, you might face difficulties as the VGA port and its associated adapters aren’t always reliable.

Step 2: Assessing your Android Device’s Capabilities

The type of connections your Android device supports can greatly influence your options for connecting it to a projector. Some newer devices, specifically those from brands like Samsung, support an adapter that allows you to transmit data directly from the USB or USB-C port on your phone to the HDMI port on a TV or projector.

MHL Support in Android Devices

Many Android devices support MHL (Mobile High-Definition Link). If your device has this feature, you can buy an MHL to HDMI adapter that plugs into your phone’s USB or USB-C port. (You can find several great adapter options on platforms like Amazon.) Just ensure you pay attention to the version of MHL your device requires and that the adapter you buy supports that version.

Step 3: Sourcing the Right Adapters

One of the most critical aspects of connecting an Android device to a projector using USB or USB-C is ensuring you have the right cables and peripherals. For this process, you may need an adapter that’s compatible with your specific phone model.

If possible, find an adapter made by the same company as your phone. This is the best way to ensure that it will work reliably with your device. Although this might mean spending a few extra dollars, the investment is worth it in the long run, since generic adapters are generally less reliable.  (You can find some great adapter options on >>>Amazon.)

Step 4: Assembling the Connection

For most people, the final step is as simple as connecting the HDMI cable to both your projector and your Android phone, then making sure the projector is set to the correct input. If the devices won’t communicate, try restarting them with the cable connected.

In conclusion, once you have all the right pieces in place, connecting your Android device to a projector with a USB or USB-C cable becomes an easy task! It all comes down to understanding your devices’ capabilities and acquiring the right tools for the job. With a compatible HDMI cable, an Android device with the right ports, and a projector with functional HDMI ports, you can establish a connection that allows you to project your phone’s content onto a larger screen. Whether you’re hosting a movie night or delivering a presentation, this guide to connect an Android phone to a projector should serve as a valuable resource. Enjoy your viewing experience!


What if my phone doesn’t support MHL or HDMI adapters?

If this is the case, you actually won’t be able to make a wired connection between your projector and phone using USB. This doesn’t mean all is lost, however. You can still connect your phone to the projector wirelessly. If your projector doesn’t have native wireless support, you can buy an adapter that plugs into the device’s HDMI port.

For Android phones, the two simplest ways to send a wireless signal are Chromecast and Miracast. Both require a specific adapter as well as an active Wi-Fi network to function. These options don’t exist for iPhones, unfortunately, but since modern iPhones are VGA compatible it shouldn’t be an issue. >>> If you’re searching for the Best Mini Projector for iPhone

Can I use the projector remote to control playback of content from my phone?

Not if you’re using a wired connection. Basically, you’ll just be projecting whatever is happening on your phone, so you’ll still navigate apps, choose your program, and play it the same way you normally would for watching a movie or show on the phone itself. The only things you’ll control using the projector remote are things specific to that device, like the picture and volume.

I’m getting sound but no picture (or vice versa). What should I do?

First, make sure it’s not user error. If there’s no picture, verify the projector is on the correct input channel and that the lamp is powered on. If there’s no sound, make sure neither your projector nor your phone is on mute and that the volume is at your usual listening level.

If all of those details are in place, this likely means there’s an issue with the equipment that you’re using. It could be that your adapter isn’t quite compatible with your phone. Double-check the adapter’s stats against your phone’s and your projector’s and buy a different adapter if it doesn’t match.

The cable can play a role in this too, especially if you’re repurposing an older cable you had laying around your house. Just because the connections fit doesn’t mean it’s the right cable for your signal type. Buy a new cable that’s certified to be used for your devices and connection method and this should solve the problem.
