34-Inch Curved Ultrawide for Colour Work
The ViewSonic VP3456a is a 34-inch curved ultrawide monitor built for colour-critical tasks. Its VA panel delivers UWQHD 3440 x 1440 resolution at 75 Hz with 16.7 million colours and a 4000:1 static contrast ratio. The 21:9 aspect ratio and 178-degree viewing angles suit multi-window creative workflows. Anti-glare coating reduces reflections in bright studios.
100 W USB-C with RJ45 for Single-Cable Docks
The monitor provides 100 W power delivery over USB-C alongside DisplayPort and HDMI inputs. An integrated RJ45 port carries wired networking through the same cable. This single-connection dock capability decides whether the VP3456a fits a laptop-centric desk that needs charging, video and Ethernet simultaneously. FreeSync support adds variable refresh for smooth motion.
400 Nits Brightness and Low-Glare Comfort
Typical brightness reaches 400 cd/m2 with a 5 ms grey-to-grey response time. The VA panel’s high static contrast keeps blacks deep without local-dimming artefacts. Anti-glare surface and wide viewing angles maintain colour consistency during long sessions. Power draw and acoustic output remain low in normal office use.
