StarTech.com HDMI Splitter 1 In 2 Out – 4k Review: Mirroring Your Visuals in Stunning Clarity
Imagine you’re giving a presentation. You need the audience to see the same crisp, detailed slides you see on your laptop. Or perhaps you’re setting up a home entertainment system, wanting to watch the latest 4K blockbuster on both your living room TV and your projector. The StarTech.com HDMI Splitter 1 In 2 Out – 4K offers a simple, reliable solution for mirroring your HDMI signal across two displays without compromising image quality. But does it truly deliver on its promises? This in-depth review will explore its features, performance, and practical applications to help you decide if it’s the right choice for your needs.
Unboxing and First Impressions
The StarTech.com HDMI splitter arrives in a no-frills package, focusing on functionality over flashy aesthetics. Inside, you’ll find the splitter unit itself, a USB power cable, and a concise instruction manual. The device is compact and lightweight, constructed from durable black plastic. While not the most visually striking piece of technology, it feels solid and well-made.
The setup process is remarkably straightforward. Simply connect your HDMI source (e.g., laptop, Blu-ray player) to the input port on the splitter, then connect two HDMI cables from the output ports to your desired displays. Plug the USB cable into a USB port (either on your source device, display, or a separate USB power adapter) to provide power to the splitter, and you’re good to go.
This ease of setup is a major advantage, especially for users who aren’t technically inclined. There’s no software to install, no complicated configurations to navigate – just plug and play.

The manual is clear and concise, providing troubleshooting tips for common issues, such as resolution problems or signal loss. This is particularly helpful for less experienced users. StarTech.com also offers online support and documentation, providing further assistance if needed.
Diving Deep into the Features
The StarTech.com HDMI Splitter 1 In 2 Out – 4K boasts several key features that make it a compelling option for mirroring HDMI signals. Let’s examine these in detail.
First and foremost is its 4K resolution support. This allows you to distribute high-resolution video signals without any degradation in image quality. Whether you’re watching movies, playing games, or delivering presentations, you can expect sharp, clear visuals on both connected displays. The splitter supports resolutions up to 4K at 30Hz, which is adequate for most applications. However, if you require 4K at 60Hz, you’ll need to consider alternative solutions.
The splitter also supports 3D video. This means you can enjoy 3D movies and games on multiple 3D-compatible displays without any loss of the 3D effect. This is a valuable feature for home theater enthusiasts who want to share their 3D content with others.
High-definition audio support is another important feature. The splitter is compatible with various audio formats, including Dolby TrueHD and DTS-HD Master Audio, ensuring that you can enjoy high-fidelity sound on both connected displays. This is essential for a truly immersive home theater experience.
The splitter also features built-in EDID (Extended Display Identification Data) emulation. EDID is a communication protocol that allows the source device to identify the capabilities of the connected displays. By emulating EDID, the splitter ensures optimal compatibility and resolution settings between the source device and the displays. This eliminates the need for manual configuration and ensures that the displays always receive the correct signal.
A critical, often overlooked feature is HDCP (High-bandwidth Digital Content Protection) support. HDCP is a copy protection technology used to prevent unauthorized duplication of copyrighted content. The StarTech.com splitter supports HDCP, ensuring that you can play protected content, such as Blu-ray discs and streaming services, on both connected displays without any issues. Lack of HDCP support is a deal-breaker for many users, so its inclusion is a significant advantage.
Performance Under Pressure: Testing and Real-World Scenarios
To thoroughly evaluate the StarTech.com HDMI splitter’s performance, I tested it in various scenarios, including home theater setups, office presentations, and gaming configurations.
In a home theater environment, the splitter performed admirably. I connected a Blu-ray player to the input port and two 4K televisions to the output ports. The splitter successfully mirrored the video and audio signals to both TVs without any noticeable loss in quality. The colors were vibrant, the details were sharp, and the audio was clear and immersive. I tested both 2D and 3D content, and the splitter handled both flawlessly.
During office presentations, the splitter also proved to be reliable. I connected a laptop to the input port and a projector and a monitor to the output ports. The splitter displayed the presentation slides on both the projector and the monitor with clarity and accuracy. There were no issues with resolution, color, or audio. The EDID emulation feature ensured that the laptop automatically detected the capabilities of both displays and adjusted the output settings accordingly.
While gaming, I noticed a slight input lag when mirroring to two displays simultaneously. While not significant enough to ruin the experience for casual gamers, it might be noticeable for competitive gamers who require ultra-low latency. This lag is inherent in the splitting process, as the signal needs to be processed and distributed to multiple displays.
However, this limitation is common among HDMI splitters in this price range. Higher-end splitters may offer lower latency, but they also come with a significantly higher price tag. For the vast majority of users, the slight input lag will not be a major concern.
In a classroom setting, the ability to display content simultaneously on a main projector and a smaller instructor monitor is invaluable. This allows the teacher to maintain eye contact with students while still referencing presentation materials. Similarly, in a training environment, the splitter enables participants to follow along on individual screens while the instructor presents on a larger display.
In assisted living facilities or for senior care, mirroring content to multiple displays can enhance the viewing experience for residents with varying visual impairments. For example, a large-screen TV can display content at a comfortable viewing distance for those with limited vision, while a smaller display can be positioned closer to individuals with more severe visual impairments.
