Your GPU's got one DisplayPort. Your workflow needs two screens. You're either squinting at a single monitor or hunting for a docking station that costs triple what it should.
The Simplecom CM214 splits that one DP 1.4 output into two. Extended mode (MST) gives you dual 4K@120Hz. Mirrored mode pushes up to 4K@144Hz. No extra GPU slot. No driver install. Plug it in, set your display layout in Windows, done.
Aluminium body keeps it cool at just 35g. Built-in 3.5mm audio out means your speakers don't need a second cable. USB-C powered – pop the included 5V2A adapter into any wall socket for 120Hz+ refresh rates.
Heads up before you buy: MST extended mode needs a native DP output from a discrete GPU or Intel 6th Gen Skylake (or later). A docking-station DP port won't do extended. macOS runs mirrored only. If you're on Windows 10 or later with the right GPU, this is your two-screen fix without buying new hardware.
In stock and ready to ship. Add it to cart and sort that second screen today
