If you’ve ever struggled with juggling multiple devices — gaming consoles, streaming boxes, cable, and surround sound systems — then you know how frustrating it can be to constantly swap HDMI cables. The solution? A 4K HDMI splitter that lets you connect multiple devices to multiple screens at once.
In this post, we’ll review the Blu Sky 4K HDMI Splitter, compare it to the popular Monoprice 4×2 model, and show you why it’s one of the best HDMI splitters for gaming, streaming, and home entertainment setups in 2025.
What Is an HDMI Splitter and Why You Need One
Before diving into the details, let’s quickly clarify what an HDMI splitter actually does.
A HDMI splitter works similarly to a network or Ethernet splitter. It takes multiple input devices (like your PlayStation, Xbox, cable box, and sound system) and allows you to output them to two or more TVs, monitors, or projectors simultaneously.
For example:
- Input 1: PlayStation
- Input 2: Xbox
- Input 3: Cable Box
- Input 4: Surround Sound
From there, you can use the remote or manual buttons on the device to control which input appears on each screen.
💡 Real-World Example:
If you have two TVs side by side and want to play Xbox on both screens, you can simply select the same input for both outputs — no more plugging and unplugging cables every time.
The Problem: Limited HDMI Inputs
Modern TVs often come with just 2–3 HDMI ports. If you own multiple devices — especially in a gaming or entertainment setup — you’ll quickly run out of inputs.
That’s where an HDMI splitter shines. Instead of constantly swapping cords, you can keep all your devices connected at once and switch between them instantly with a remote.
For families with kids or roommates, this can save a lot of time (and arguments) about who gets to use the TV next.
Blu Sky 4K HDMI Splitter vs. Monoprice 4×2 Splitter
Let’s compare the two models featured in the video:
Monoprice 4×2 Splitter
This older model is a 4-input, 2-output splitter. It’s reliable but lacks modern 4K capabilities.
- Inputs: 4
- Outputs: 2
- Resolution: Up to 1080p
- Extras: Basic remote, power cable
Blu Sky 4K HDMI Splitter (2025 Model)
The Blu Sky model is the upgraded version with 4K Ultra HD support and improved compatibility for modern TVs, monitors, and projectors.
- Inputs: 4
- Outputs: 2
- Resolution: Up to 4K at 60Hz
- Extras: Compact remote, power adapter, auto-switching feature
💡 Key Upgrade:
4K support means the Blu Sky delivers sharper, crisper images, making it ideal for next-gen gaming or streaming 4K content from platforms like Netflix, Disney+, and YouTube.
Why the Blu Sky 4K HDMI Splitter Is a Great Upgrade
1. True 4K Compatibility
This splitter supports 4K resolution without downgrading picture quality. Whether you’re gaming on a PS5 or watching movies on a 4K TV, you’ll get full resolution and color depth across multiple screens.
2. Simplified Device Management
Instead of juggling cords, the Blu Sky splitter’s remote lets you instantly switch between connected devices. You can control which input goes to which screen in seconds.
3. Perfect for Multi-TV Homes
If you have two TVs in the same room — or one in your living room and one in your kitchen — this device lets you show the same content on both without lag or signal loss.
4. Family-Friendly and Hassle-Free
Parents love this feature: you can set one screen for kids’ shows while keeping your own content on another. No more negotiating TV time.
5. Reliable Build Quality
Blu Sky’s device is sturdy and reliable, with an aluminum casing and heat-resistant design to prevent overheating during long gaming sessions.

How to Set Up the Blu Sky 4K HDMI Splitter
Setting up this device takes less than 5 minutes. Here’s how:
Step 1: Connect Your Devices
Plug your input devices (gaming consoles, streaming boxes, or Blu-ray players) into the HDMI IN ports.
Step 2: Connect Your Displays
Connect your TVs, monitors, or projectors to the HDMI OUT ports.
Step 3: Add Power
Plug in the power adapter — this splitter requires an external power source to function properly.
Step 4: Test and Switch Inputs
Use the included remote to toggle between devices and assign which screen shows which input.
That’s it! Your entertainment hub is now ready.
What Makes the Blu Sky HDMI Splitter Stand Out
1. Plug-and-Play Setup
No software or drivers needed. Simply connect your devices, plug it in, and it’s ready to go.
2. Compact and Discreet
Despite its power, the device has a small footprint and fits neatly behind your TV or on your media shelf.
3. Multiple Model Options
Depending on your setup, you can choose from:
- 1×2 (1 input, 2 outputs)
- 1×4 (1 input, 4 outputs)
- 4×2 (4 inputs, 2 outputs)
4. Future-Proof Design
The Blu Sky splitter is compatible with HDCP 2.2 — meaning it works with newer devices like PS5, Xbox Series X, and 4K streaming sticks.

- Family rooms: Share one cable box across multiple TVs.
