ViewSonic VG3456CA – 34-Inch Ultrawide WQHD USB-C Monitor

Product Overview

The ViewSonic VG3456CA is a 34-inch UWQHD curved USB-C docking monitor designed for enterprise workstations where a single-cable connection replaces a separate dock. Its 21:9 ultrawide 3440x1440 VA panel with 1500R curvature provides expanded screen real estate equivalent to two 27-inch monitors side-by-side without a bezel gap, making it well-suited for financial analysis, development, and multi-application workflows. With 100W USB-C power delivery, built-in RJ45 Ethernet, and an integrated USB hub, it consolidates display, network, and peripheral connectivity through one cable to a connected laptop.

Product Description

The VG3456CA uses a 34-inch VA panel at UWQHD 3440x1440 resolution with a 1500R curvature, 100Hz refresh rate, and 350 cd/m² brightness. The 21:9 aspect ratio provides 33% more horizontal screen space compared to a standard 16:9 display of similar height, allowing users to view multiple application windows, spreadsheets, or code editors side-by-side without virtual desktops or constant window switching. The built-in docking station delivers 100W USB-C power delivery, RJ45 Ethernet connectivity, and a four-port USB-A hub, eliminating the cost and cable complexity of a standalone dock in laptop-centric deployments. A secondary USB-C port provides 15W charging for phones or tablets. Two HDMI 2.1 inputs and one DisplayPort input maintain compatibility with desktop PCs, conference room systems, and other video sources without USB-C. ViewSonic's vDisplayManager software provides on-screen OSD control and split-screen window layout management, useful for multi-tasking across the wide panel. The ergonomic stand supports 110mm height adjustment, 120° swivel, and 5°/40° tilt, accommodating a wide range of user positions. Integrated 5W stereo speakers, a Kensington lock slot, and VESA 100x100mm mounting complete the feature set. An ENERGY STAR 8.0 and EPEAT Silver rating supports sustainability procurement goals in enterprise and government environments.
