Comprehensive Review of the Duex Float Portable Stacked Monitor Extender
For those who thrive in a productive work environment, a large monitor is often an essential tool. Personally, I have a spacious 34-inch ultrawide display connected to my desktop, complemented by a 27-inch external monitor when stationed at my office workstation. However, this blissful setup detours whenever I have to travel with my laptop. Enter the Duex Float portable monitor extender! This innovative solution offers a means to boost productivity while on the move. Let’s dive into how the Duex Float performs and whether it’s a worthy investment.
Setting Up the Stacked Monitor
The Duex Float is optimized for a vertically stacked monitor configuration that utilizes a kickstand plate attached to your laptop’s screen. While some users may prefer to extend their workspaces horizontally, the vertical design proves advantageous for smaller desks, maximizing space without compromising productivity. Adapting to this setup may require a shift in your usual workflow, but it can ultimately lead to a more organized workspace.

Unboxing Experience
Upon receiving the Duex Float, my initial reaction was its substantial heft. Weighing in at 4 lbs (1.8 kg), it surpasses both my 15-inch laptop and my Chromebook, making it feel akin to carrying a small brick. This added weight can be a downside for frequent travelers, as it demands careful consideration when packing for mobility.

Weight aside, the design necessitated this bulk—sturdy hinges and a robust kickstand plate are paramount for upright stability. The unboxing reveals a minimalist collection of accessories: one HDMI cable, a USB-C cable, a magnet pack, and the instruction manual.

Modes of Usage
Applying the monitor extender begins with adhering the supplied magnets to your laptop cover using the provided alignment template. However, this permanent adhesion may limit usage across multiple devices.
Once successfully attached, you can firmly secure the kickstand and adjust the hinge to position the monitor directly above your laptop screen. Next, connect the corresponding cable, and you’re ready to go!
Sadly, I encountered challenges with this magnetic attachment. Variations in magnetic parity across my laptop’s surface prevented proper attachment. So, opting to use the monitor without the magnets became a necessity, and luckily, it stands independently well. The Duex Float showcases three distinct modes:
- Stacked Extended Monitor Mode: This mode extends your display vertically, which is the default setting.
- Stacked Presentation Mode: Rotate it 180° for a back-facing monitor—ideal for presentations to clients or colleagues across the table.

- Desktop Mode: Prefer a horizontal extension? In this mode, the monitor can lie next to your laptop, functioning independently. This mode also seamlessly connects to consoles for gaming on the go!

Exploration of Ports
One notable characteristic of the Duex Float is the placement of its ports. Unlike traditional monitors, the Duex Float houses all connections on the kickstand, which complicates matters as you cannot utilize the monitor independently from it. The unit is fitted with one mini HDMI port and two USB-C ports, allowing various connection options.
Understanding port functionalities is crucial. Connecting via HDMI necessitates an external power source through the USB-C port, as HDMI alone does not allow pass-through power. Conversely, utilizing USB-C allows for power to draw directly from your laptop, streamlining the process to a single cable when using compatible laptops. Importantly, touchscreen features function only through USB-C connections. This limitation isn’t adequately highlighted in the manual, potentially confusing users without USB-C ports.
The touchscreen supports both Windows and macOS natively, though I discovered it seamlessly works even on my Arch Linux setup, marking it as versatile across platforms.

Performance Evaluation
The general responsiveness of the Duex Float matched expectations during its use with my Dell laptop. However, when connecting to my Chromebook, I experienced occasional lag while typing. This leads me to deduce that performance fluctuations can often stem from the connected device rather than the monitor itself, underscoring the importance of device compatibility.
Final Thoughts
The standout feature of the Duex Float is its unique kickstand design, facilitating a stacked monitor setup. Furthermore, its transformation into presentation mode is particularly beneficial for professional environments. While the weight may dissuade some users, if you are committed to a stacked monitor configuration and can adapt, the Duex Float could be a valuable addition to your toolkit.
