If you’ve ever tried connecting multiple devices to your TV or wanted to show the same video on two screens, you’ve probably heard of HDMI splitters and HDMI switches. These two devices are commonly used in our daily, but their similar names can cause confusion. Now let’s explore them in the following content. After reading this article, you can pick the right tool for your home theater, gaming setup, or workspace.

What is an HDMI switch?

An HDMI switch lets you connect multiple computers to a single TV or monitor (many to one). It solves the “not enough HDMI ports” problem, so you don’t have to crawl behind your TV to swap cables. Also, some HDMI switches are designed with KVM features, which allow users to control multiple computers by using a keyboard and mouse. And to make the management more convenient, some HDMI KVM switches are designed with widescreen LCD modules and built-in keyboards and touchpads.

How do HDMI switches work?

Connect devices: Connect your PlayStation, Apple TV, and PC to the switch’s inputs.

Switch between connected devices: Use a button, remote, or auto-detection to choose which device appears on the screen.

When to Use an HDMI Switch?

Limited HDMI Ports: Connect a soundbar, gaming console, and streaming stick to a TV with only two ports.

Hybrid Workstations: Switch between a work laptop and gaming PC on a single monitor.

AV Equipment Management: Reduce cable clutter in entertainment centers.

Data Centers: Manage multiple computers or servers from a single console to optimize space utilization and improve management efficiency.

Limitations

• Only one device can be active at a time.
• Cheap switches may introduce lag or signal drops.

What is an HDMI splitter?

We can briefly introduce that this device can share one source with multiple screens. An HDMI splitter takes one video source (like a laptop, game console, or cable box) and sends the same signal to multiple displays. Imagine watching a movie on your living room TV and bedroom TV at the same time—without moving the Blu-ray player.

Key Features of HDMI Splitter

High Resolution: HDMI splitters support high-resolution formats like 4K, 1080p, or HDR, with compatibility varying depending on the selected models.

Mirroring Content: It is ideal for mirroring content across multiple screens, including scenarios such as sharing presentations, monitoring security camera feeds, or broadcasting live gaming streams.

How do HDMI splitters work?

Connect the source: Plug your device (e.g., a PlayStation) into the splitter’s input.

Split the signal: The splitter duplicates the video/audio feed.

Send to displays: Hook up two or more TVs, monitors, or projectors to the splitter’s outputs.

When to Use an HDMI Splitter?

Multi-Room Streaming: Watch the same movie on your living room TV and patio projector.

Live Events: Broadcast a sports game or party playlist to multiple TVs.

Presentations: Show slideshows on two monitors in a conference room.

Limitations

• All connected screens show the same content.
• Lower-quality splitters may struggle with high-resolution signals over long distances.

HDMI Splitter vs. Switch: Quick Comparison (key differences)

Feature	HDMI Splitter	HDMI Switch
Purpose	Duplicate one source to many screens	Connect many devices to one screen
Use Case	Mirroring content	Expanding TV/display ports
Complexity	Plug-and-play setup	May require manual input-switching

Conclusion

An HDMI Splitter is an ideal device that can broadcast a single source like a gaming console or streaming device to multiple screens simultaneously. By doing that, the content can be shown on all screens synchronously. On the other hand, an HDMI switch is used to manage several input devices like laptops and computers from a single console (keyboard, mouse, monitor), which can eliminate redundant USB peripheral devices. Importantly, these two devices can help you improve efficiency and provide you with a comfortable experience.
