Guide to 4K HDMI Projector: From Selection to Connection

By XGIMI Tech - 2025-4

4K HDMI projectors bring cinematic visuals and versatile connectivity to any space. Whether you’re streaming movies, gaming, or presenting, this guide covers picking the one, recommendations, and step-by-step HDMI setup tips.

What is the Best 4K HDMI projector?

The “best” 4K HDMI projector depends on your priorities: cinematic quality or seamless connectivity. For movie enthusiasts, focus on HDR performance, color accuracy, and contrast ratios. For gamers, however, high-profile HDMI 2.1 support for 4K@120Hz, VRR, and ultra-low latency is recommended.

However, the XGIMI 4K HDMI projectors are one of the best options you can choose. Some models like HORIZON S Pro offer a single HDMI 2.1 port with eARC, delivering stunning 4K visuals and immersive audio through a single cable—perfect for hassle-free streaming. Some models with dual-HDMI like HORIZON Ultra enable simultaneous connections, separating video and audio signals for theater-grade performance.

Whether you crave simplicity or versatility, XGIMI balances cutting-edge tech with user-friendly design.

How to Connect Devices to Your 4K Projector for Videos or Music?

For seamless HDMI connectivity across different kinds of devices for watching movies, gaming, streaming, or presenting, follow the steps below:

1. Confirm HDMI Compatibility

Before connecting any device, check the HDMI versions(2.1, 2.0, or 1.4) of both your source device (e.g., laptop, gaming console) and the digital projector 4K with HDMI.

2. Choose the Right HDMI Cable

Not all HDMI cables are the same. You should find the most suitable cable for your device versions among three types of HDMI cords: Ultra High-Speed HDMI (48Gbps), High-Speed HDMI (18Gbps), and Standard HDMI (Which is Only for 1080p or lower resolutions).

For example, a PS5 connected to a 4K@120Hz projector requires an Ultra High-Speed HDMI cable.

An HDMI Cable Adapter is Needed to Connect iPhone, Android, or Tablet to Projector 4K

iPhones/iPads: Use a Lightning-to-HDMI or USB-C-to-HDMI adapter (for newer iPads). Enable “Mirror Display” in Settings to project content.

Android Phones/Tablets: Requires a USB-C-to-HDMI adapter (ensure your device supports HDMI Alt Mode). Samsung DeX or Huawei Desktop Mode can transform your phone into a PC-like interface.

3. Connect Devices to Projector via Cable

Plug one end of the HDMI cable into your device’s output port and the other into the 4K projector’s HDMI input. Ensure the connection is secure.

4. Adjust Device Settings like Resolution, Refresh Rate, and Audio

After connecting, configure the output settings on your source device:

Resolution: Set to the projector’s native resolution of 4K or 1080p.

Refresh Rate: Match the projector’s max supported rate (e.g., 60Hz or 120Hz).

Audio: Select “HDMI Output” for sound (if using the projector's built-in speakers) or route audio to an external system.

On a Windows PC, you may try going to Settings > System > Display > Advanced Display Settings to adjust the resolution/refresh rate.

Note:

1. A signal booster may be required for HDMI cables longer than 5 meters.

2. Avoid cheap adapters: they often fail to transmit 4K or HDR signals.

Conclusion

Transform your space with a 4K HDMI projector—where stunning clarity meets effortless connections. Ready to dive in? Grab your remote, plug in, and let the big-screen adventure begin!
