34-inch ultrawide USB-C docking monitor

The ViewSonic VG3456CA is a 34-inch curved display with a 21:9 aspect ratio and 3440x1440 resolution. An integrated USB-C dock delivers up to 100W power, Ethernet and extra USB ports for a single-cable laptop setup. It targets professionals who want expansive workspace without a dual-monitor bezel gap.

IPS panel 100Hz refresh low-blue-light comfort

The IPS panel runs at 100Hz with a 5ms response time for fluid motion in everyday tasks. Brightness reaches 350 cd/m² and the 3000:1 static contrast ratio produces deep blacks. Wide 178° viewing angles and a 1500R curvature reduce eye strain during long sessions. Flicker-free backlight and blue-light filter add further comfort.

Ergonomic stand extensive connectivity

Height, tilt and swivel adjustments let you position the screen for posture-friendly work. Two HDMI 2.0 inputs, DisplayPort and the USB-C dock with RJ45 cover most modern laptops and desktops. The anti-glare coating cuts reflections in bright offices. Buyers who need higher refresh rates for competitive gaming or colour-critical calibration hardware support should look elsewhere.

Questions about this item

How do I connect the VG3456CA to a laptop so the single cable carries video, data and 100W charging?

Plug a USB-C cable that supports 100W power delivery into the monitor's upstream USB-C port; the same link drives the 3440x1440 100Hz signal, the integrated USB hub and the RJ45 Ethernet port.

Which parts of the VG3456CA are most likely to need replacement after years of daily use?

The LED backlight and the USB-C docking electronics are the components that typically age first; the VA panel itself is rated for long-term static contrast of 3000:1.

What limit appears first when the VG3456CA runs at 100Hz for extended periods?

The 5ms response time and 350 cd/m² brightness ceiling are the first constraints you hit during sustained high-refresh workloads.
