Shenzhen E-Tech Launches Industry-First 18.5 Inch 1080P FHD Portable Quad Monitor with 360° Rotatable Screens

Industry-First 18.5 Inch Portable Quad Monitor S999 Launched by Shenzhen E-Tech

Shenzhen, China — Shenzhen E-Tech Digital Technology Co., Ltd., a professional portable display manufacturer established in 2006, has officially launched the S999 18.5-inch portable quad monitor — the industry's first portable quad-display monitor featuring a super-large 18.5-inch main screen. This breakthrough product is designed to redefine mobile productivity for traders, business professionals, content creators and on-the-go office workers.

A Breakthrough in Screen Size

Portable quad monitors on the market have long been limited to compact panels that compromise visual comfort. The S999 changes the game with an 18.5-inch IPS display delivering crisp 1920*1080 Full HD resolution in a 16:9 widescreen format. Whether you are monitoring real-time stock charts, editing videos, comparing documents or enjoying entertainment, the S999 presents every detail with stunning clarity and color accuracy.

One Cable, Three Displays

Setting up the S999 is effortless. A single USB-C to USB-C cable connects the monitor to your laptop for both video and power, instantly extending your workspace into four screens. For laptops without a USB-C port, a USB-A to USB-C cable is supported, with the monitor powered by the included PD 45W power supply.

360° Rotatable Screens for Any Scenario

The S999 features an innovative rotation system: the top screen flips 0–300° while the left and right screens rotate a full 0–360°. Multiple alternative display modes adapt to different working scenarios — from multi-chart trading desks to collaborative presentations and immersive entertainment.
