The Mobile Pixels Duex Float is specially designed for laptops with a screen size of around 15 to 16 inches. It is therefore not optimally designed for a Surface with only 14 inches. The brackets and the magnetic mounting system are designed for this size category, which is why the fit and stability are not guaranteed with a 14-inch device. It is also recommended to use the built-in stand if the magnetic attachment does not fit perfectly.

The device should generally fit a Lenovo ThinkPad X1 Yoga Gen 6, as it has USB-C and Mini HDMI, which is typically compatible with modern laptops. However, you should make sure that your ThinkPad X1 Yoga Gen 6 has the necessary ports and supports the display extension.
