Product Identity

The ViewSonic VG3420C is a 34-inch curved IPS monitor with a 21:9 UWQHD resolution of 3440×1440 and a 120 Hz refresh rate. It is built for professionals who need a wide, colour-accurate workspace for multitasking across spreadsheets, dashboards and creative applications. The 1900R curvature keeps the screen edges within a natural field of view. A 96 W USB-C connection supplies video, data and power through one cable.

Sustained Operation

The IPS panel maintains a static contrast ratio of 2000:1 and a brightness of 300 cd/m² during extended sessions. With 98% DCI-P3 coverage and HDR10 support, colour accuracy remains stable for long creative or analytical workloads. A 5 ms response time and 178° viewing angles ensure consistent image quality across the ultra-wide canvas without noticeable degradation over time.

Installation Notes

The monitor includes HDMI 2.0, DisplayPort 1.4, USB-C, USB 3.2 Type-A and Type-B ports plus a 3.5 mm audio output, all cables supplied in the box. The stand provides height, swivel and tilt adjustment for ergonomic positioning. Ensure the graphics source can drive 3440×1440 at 120 Hz over the chosen interface; older HDMI ports may limit the refresh rate.
