18.5″ IPS Panels — Maximum Screen Area for Professionals

Unlike portable monitors with smaller 14″ or 16″ panels, each of the three extended screens in the S999 measures a full 18.5 inches diagonal — the same size as a compact desktop monitor. The IPS panel delivers 178° wide viewing angles and sRGB 100% color accuracy, making the S999 the right choice for video editing, graphic design, color-critical work, and data-heavy trading setups that demand the most visible screen area possible.

Quad-Screen Extension with Foldable Design

The S999 instantly expands your laptop into a four-screen workstation using three fold-out panels — left, top, and right. With a compact and foldable frame, it is engineered for portability and sets up in seconds on any flat surface, whether at a coffee shop, client site, or hotel desk.

Single Cable for 3 Extended Displays

One cable powers all three extended screens and transmits the video signal simultaneously. The S999 supports USB-C to USB-C for laptops with a USB-C or Thunderbolt port. For older laptops without USB-C, the included USB-A to USB-C cable works when a PD power adapter is connected to the monitor. Plug-and-play with Windows 10/11; macOS requires the included driver disk for first-time setup.

Flexible Viewing Angles — 360° Rotation + Auto-Sensing Top Screen

Independent Rotation on All Screens

The S999 features full 360° rotation on both left and right 18.5″ displays, and up to 300° on the top screen. The top screen includes auto-sensing technology that automatically flips the display orientation when the panel is physically rotated — no manual setting adjustment needed. This enables flexible multi-angle setups for portrait coding, mirrored collaboration, or vertical data stacking. A built-in adjustable back stand keeps the system stable on any flat surface.

sRGB 100% — Professional-Grade Color Accuracy

The S999 covers 100% of the sRGB color space straight out of the box. Unlike monitors with 72% NTSC coverage, sRGB 100% ensures that the colors you see on screen match your source files and final output — essential for photo editors, video colorists, UI/UX designers, and anyone working with branded materials. No calibration required for standard sRGB content workflows.

Compatible with 12″–18.5″ Laptops — Windows & Mac

The S999 is designed to attach to laptops between 12 and 18.5 inches. It supports Windows 10 and Windows 11 natively, with automatic driver installation when connected to the internet. For MacBooks from 2019 onward — including all M1, M2, M3, and M4 chip models — install the included driver using the USB disk before first use.
