Content from the small smartphone display onto a Huge canvas to project, transforms your living room into an impressive home cinema that surpasses traditional televisions in many respects (see also our comparison: Projector or TV. But how exactly do you establish the connection? The process is easier than many people think.

Whether you're looking for the maximum image quality of a wired connection or prefer the flexible freedom of a wireless solution, this guide will take you step by step to your goal. We'll explain the technical basics, show you the best methods for Android and iPhone, and help you quickly solve common problems.

Before you start: A quick 2-minute checklist

A good preparation will save you time and possible frustration. Check these three points before buying cables or adapters.

Check the connections: What does your phone have, what does the projector have?

Look briefly at the ports on your devices. Modern smartphones use almost exclusively one of two standards:

• USB-C: The oval, symmetrical connector. Standard on all current Android devices and on iPhones from the iPhone 15 onward.

• Lightning: The smaller, also symmetrical connector for iPhones up to and including model 14.

Your projector will most likely have one or more HDMI ports have as an input. This is today’s standard for transmitting image and sound.

The most important question: Does your phone support video output via USB-C?

This is the most critical point for a wired connection on many Android devices. Not every USB-C port can output a video signal. The function required for this is called DisplayPort Alternate Mode. While high-end smartphones usually have this feature, it is missing from many mid-range and entry-level devices.

Check it like this: If "DisplayPort Alternate Mode" or "video output via USB-C" is listed there, you're on the safe side.

Choose the correct source on the projector

One frequently overlooked step: the projector needs to know which input it should receive the signal from. To do this, press the button labeled on your projector remote control "Source", "Input" or a symbol showing a rectangle and an arrow. Then select the correct HDMI input (e.g. "HDMI 1" or "HDMI 2").

Method 1: The wired connection – Maximum quality and stability

For the best possible picture and sound quality, without delays or stuttering, the cable is the first choice. This is the ideal method for movie lovers and ambitious gamers.

For Android & new iPhones (from iPhone 15): connection via USB-C to HDMI

If your smartphone supports video output via USB-C, connecting it is incredibly simple. All you need is a USB-C to HDMI cable or an appropriate adapter.

1. Connect the USB-C end of the cable to your smartphone.

2. Plug the HDMI end into an available HDMI input on your projector.

3. Select the correct input source on the projector. Your phone's screen content should now automatically appear on the screen.

Expert Tip: Pay attention to a high-quality cable to ensure full 4K resolution and modern standards such as HDR. The difference in image dynamics is enormous, like our Comparison of SDR vs. HDR shows in detail.

For older iPhones (up to iPhone 14): The Lightning to Digital AV Adapter

For iPhones with a Lightning connector, you need the Apple Lightning to Digital AV Adapter.

1. Plug the adapter into your iPhone's Lightning connector.

2. Connect a standard HDMI cable to the adapter and the projector.

3. Choose the HDMI source on the projector.

Expert tip: We recommend using the official adapter from Apple. Cheaper imitations can cause issues when streaming copy-protected content from services like Netflix and may stop working after an iOS update. The original adapter also has an additional Lightning connector, allowing you to charge your iPhone during playback.

Method 2: The wireless connection – freedom without cable clutter

If flexibility and a tidy look are the priority, wireless transmission is the right choice.

Wichtig to know: The difference between mirroring and casting

• Screen Mirroring (Mirroring): Here, the entire screen content of your smartphone is mirrored to the projector 1:1 in real time. Every app, every notification – everything is displayed. This drains your phone's battery.

• Casting: This is the smarter method. An app (e.g. YouTube) only sends the link to the video to a receiving device (e.g. a Chromecast). This device then streams the content independently from the internet. Your phone then only serves as a remote control and can be used for other tasks or locked.

For Apple Users: AirPlay Simply Explained

AirPlay is Apple's protocol for wireless streaming. You need a projector with native AirPlay support or an Apple TV box connected to the projector.

1. Ensure that your iPhone and the projector/Apple TV are connected to the same Wi‑Fi network.

2. Open the Control Center on your iPhone (swipe down from the top-right corner).

3. Tap the screen mirroring icon (two overlapping rectangles) and select your device from the list.

For Android users: Miracast and Google Chromecast

The majority of modern projectors support the mirroring standard Miracast.

1. Enable the "Screen Mirroring" or "Wireless Projection" function on your projector.

2. Open the Quick Settings on your Android phone (swipe down from the top of the screen).

3. Look for the "Screen Mirroring", "Smart View", or "Cast" feature and tap it. Select your projector from the list of detected devices.

For the "casting" of content, a Google Chromecast-Dongle that connects to the projector's HDMI port, an excellent and affordable solution.
