Regardless how well or badly the manufacturers of tablets and convertibles design their screens, most of them keep the glass surface, which is very reflective and not always suitable in everyday usage.

Fujitsu takes a different path here, and it is not the first time that it delivers a display that wipes the floor with other touchscreens. The matte yet smooth surface is very well suited for inputs including drag-and-drop movements. The good maximum brightness value of 325 cd/m² is also sufficient to be able to still read the display easily outdoors even in direct sunlight.

The rest of the values are also not bad at all. The color space coverage in the Fujitsu Lifebook U939X reaches 96.6% in the sRGB and 62.9% in the AdobeRGB color space. At 1121:1, the contrast ratio is more than sufficient for most users, and a black value of 0.29 cd/m² ensures that dark content is reproduced with saturated depth. Since an input stylus is included, users can enjoy the full range of input options at no extra cost.

A Multitude of Connections

Another positive characteristic of the Lifebook U939X is the multitude of connections. Since the device is mainly targeted towards business users, a smart card reader is also present. But the real highlight are the two Thunderbolt 3 ports. Those offer the full range of performance, allowing you to expand the capabilities of the Fujitsu convertible in multiple ways. In addition, there is also an LTE option.

However, with all the positive impressions that remained after our test, there are also two things that spoiled our fun with the device. The keyboard and the classic touchpad urgently need some improvements. While the layout of the key positions can stay like that, Fujitsu should improve the feedback when pressing the keys. The mouse replacement was also clattering in its frame, and the surface of the touchpad is not particularly well suited for drag-and-drop movements.

Our review of the Fujitsu Lifebook U939X shows what the rest of the hardware of the Windows convertible can do.

I made my first IT walking attempts on a 386 with 4 MB of RAM. After that followed various PCs and notebooks, which I looked after and repaired in my circle of friends and acquaintances. After an apprenticeship as a telecommunications systems engineer and several years of professional experience, I graduated with a bachelor's degree in industrial engineering. Today I live out my fascination for IT, technology and mobile devices by writing test reports. In my free time I like to devote myself to vegan cooking and spend time with my family, which includes a whole range of animal roommates.
