INGNOK
A 15.6-inch foldable dual-screen extender with FHD 1080P resolution, 100% sRGB colour, 1200:1 contrast and 320 nits brightness for portable multi-tasking
The Ingnok YNF2B adds two 15.6-inch Full HD panels to a laptop through a single USB-C connection on Windows or macOS. Each screen delivers 1080p resolution, 100 percent sRGB coverage, 1200:1 contrast and 320 nits brightness on a matte surface. The foldable design measures 15.0 by 8.5 by 0.78 inches and weighs 2.631 kilograms for transport.
Coders, editors and analysts who want two extra displays for multitasking, presentations or cross-screen collaboration on Windows will benefit. Buyers who only need one additional screen or who require higher resolutions, touch input or built-in battery power should consider other form factors.
Verify the host device supplies video and power over one USB-C port with DisplayPort Alt Mode or offers separate HDMI and USB-C connections for both panels. Confirm the operating system supports the required display count; triple-screen cross-screen mode is supported on Windows only.

The YNF2B connects through one Type-C port that carries both video and power, or through an HDMI port plus a separate USB-C power port if your laptop cannot supply enough current over a single cable.
Yes, the extender adds two 15.6-inch 1080P screens alongside your existing display; Windows treats all three as independent monitors, while macOS mirrors the two extender screens together.
Open a colour-gamut test pattern or run a calibration tool; the screen should cover the full sRGB triangle at the factory 320-nit brightness and 1200:1 contrast without further adjustment.
