    Rocketfish 2-Output Ultra HD HDMI Splitter

    Introduction If you need a simple, reliable way to send one HDMI source to two screens, the Rocketfish 2-Output Ultra HD HDMI Splitter is worth a look. It’s compact, understated in black, and built for people who want clean, no-fuss connectivity whether at home or in a meeting room. I will walk through what it does well and where it might trip up so you can decide if it fits your setup (which it did for me). Design and Build The splitter looks and feels thoughtfully made. Its compact black chassis blends into most entertainment centers, and the included double-sided tape makes it easy to tuck the unit out of sight. There’s also a wall-mount option that adds flexibility for permanent installs or tidy cable runs. Overall, the design favors practicality over flash, which is exactly what you want from a utility device. Performance and Image Quality Where this unit really stands out is performance. It supports resolutions up to 8K, and in everyday use it delivers crisp, consistent images across both displays. I didn’t notice any lag or stuttering, and both outputs tended to match each other closely, avoiding the uneven brightness or color shifts that sometimes plague splitters. For streaming, presentations, or gaming, the picture quality is solid and dependable. Compatibility, Setup, and Value Setup is straightforward. The package includes a USB cable and power brick, so you have everything needed to get started right away. Most modern TVs and monitors worked without issue, but older or very old devices may struggle to recognize the signal. That’s the main caveat to keep in mind. Pros - Reliable 8K-capable output - Consistent image quality across both displays - Compact design with mounting options and double-sided tape - Includes power cable and brick for easy setup - Affordable for the performance offered Cons - May have trouble with legacy devices that don’t properly recognize the signal (mostly much older devices) This splitter strikes a good balance between price and performance. It doesn’t try to be fancy; it just does the job well. Conclusion If you want a straightforward HDMI splitter that looks neat, installs easily, and delivers high-resolution output without fuss, the Rocketfish 2-Output Ultra HD HDMI Splitter is a solid choice. It’s especially appealing for anyone who needs dependable, budget-friendly video distribution for home theaters, small offices, or classrooms. Recommended!

    Nice compact splitter

    My testing consisted of a computer with 2 monitors. You will need 3 HDMI cables that are not included. One from the splitter to your computer and one each to the monitors. Measure the length you will need and choose the smallest length that will work. Setup will take about 5 minutes or less (I had to feed cables through my desk). Very simple plug and play. The Splitter, setup guide, AC adapter and 6’ USB-A to USB-C are included in the box. It will fit easily on your desk as it is similar in size to a deck of playing cards. Specs include 8K@60Hz, HDR10 and Dolby Vision HDR compatible. I appreciate the rubber fit as it helps keep the splitter in place and not scratch my desk. Such an easy setup and it works seamlessly. Very easy to view my monitors and great for when we are watching funny videos or trying to read a document together. Just remember to do your research as splitters and switches are very different. There are several videos to help understand the concept. This will split your same image to 2 displays.

    Simple sleek HDMI splitter.

    Rocket fish is known for AVR component products. So this HDMI splitter is inline with the products and services that they offer. Setup is super simple. Comes with charger sticky tape and power cord. Looks like it runs on USB c so it is a low voltage power supply. I plugged the USB power supply adapter into the wall and then in to the HDMI splitter and the power was on. After that I picked my source and then my 2 output devices. Boom I was all setup and running. For this application I used it to split my security camera system audio and video 4K setting. My complexity is that I ran my second feed over Cat 5e to a remote Screen. It worked just fine. No complaints. No lag or noise. If I was able to do that with this complex setup it should work for a more simplistic setup that is right next to the source. Anyway if you are looking to split your HDMI output, look no further as this item will achieve what you need. Simple, compact, easy to install. Nice sleek black look. Can't go wrong.

    Does everything but EDID copy

    This is a compact splitter that passes everything correctly. However, it does not support EDID copy which is a pain, especially for Apple TV users. If Rocketfish adds support for EDID copy, this splitter is as good as anything on the market.

    Put It In Your Cart

    Definitely serves the purpose. If you're a gamer like myself. You have encountered the need for extra HDMI ports. Ever been playing COD online with your friends, then your girlfriend/ wife/ husband/ boyfriend, heck roommate comes in wanting to run a fade on you in Mario Kart. Now you've gotta reach behind the TV/ monitor to change "Switch" out your HDMI cables because you've got your cable box/ steam box connected to your only other available port. With the "Rocketfish", you can now add an extra port with this splitter. Inhave to say this almost ever time write a review. Y'all know how I love easy to install tech. If you don't know. Now you know. Technology is supposed to make our lives easier. And the first step should be simple installation. This is as simple as they come. The package hoses the small and sleek splitter box with key wholes slots, for wall mounting, a 6ft power cord, sticky strips, just in case don't want to put pin while I'm your wall. And it also comes with ISB-A power brick. I always love when companies give me a power brick. With the brick being separate, it allows you use the brick or plug it directly into USB-A on your monitor or TV. After that connect you HDMI cables and (Bob's your uncle.) Too simple. This is always good to have on hand It's small enough to take it with you on away missions, as well. Easy purchase. Even easier to use. Cart this up. And happy steaming.
