Our Verdict

The KYY X90D is a laptop screen extender rather than a standalone monitor. It attaches to the back of a 12 to 17-inch laptop lid and adds two 15.6-inch 1080p IPS screens, turning a single laptop into a three-screen workstation, and the screens rotate and fold for presentations. It connects over a single USB-C cable but needs a display driver installed, supplied on a USB drive in the box. It is far heavier than a single portable monitor and depends on your laptop's performance to drive three screens smoothly. For traders, analysts and remote workers who need maximum screen space wherever they work, it is a strong option. If one extra screen is enough, a standalone portable monitor is lighter and simpler.
