In this video, I break down how to get a true triple monitor setup on a MacBook—because a lot of people buy the wrong thing and end up with three screens showing the exact same image. I explain the real difference between “mirror” mode (what most basic HDMI splitters do) and “extend” mode (what you actually want for a productivity-focused desk setup). If your goal is to have three independent displays so you can edit, research, and keep tools open at the same time, you need a solution that supports extended desktops—not just duplicated output. I also walk through why OREI’s SplitXtend USB-C docking approach is different: it takes one USB-C connection and turns it into multiple HDMI outputs that behave like separate monitors. I share practical use cases for home offices, creator setups, and streaming/gaming rigs, plus general compatibility notes for Mac, Windows, and USB-C laptops. The big takeaway: if you’re building a smarter workflow, don’t waste money on an HDMI splitter expecting “more screens.” Pick the right tool for true multi-monitor extension and your desk setup instantly becomes more efficient.
