ViewSonic VX4381-4K 43" 4K 75Hz MVA monitor

43-inch 4K MVA monitor for productivity

The ViewSonic VX4381-4K is a 43-inch Ultra HD display built around a 3840 x 2160 MVA panel with a 75Hz refresh rate and 3 ms response time. It targets professionals who need a single large screen for document editing, graphic design and multitasking without a multi-monitor setup. MultiPicture support lets you view up to four 1080p sources simultaneously. HDR10 compatibility adds a wider colour range for supported content.

Thermals noise and power

The monitor uses an energy-saving Eco-mode to reduce power draw during typical office workloads. Flicker-Free technology and a built-in Blue Light Filter keep the backlight stable and lower eye strain over long sessions. With a peak brightness of 450 cd/m2 and a static contrast of 4000:1, the panel delivers consistent luminance without audible fan noise in normal use. The flat cabinet stays cool under sustained desktop operation.

Connectivity decides fit

Video inputs comprise two HDMI 2.0 ports, one DisplayPort 1.4 and one Mini DisplayPort 1.4, so the monitor works with laptops, desktops and Macs that drive 4K at 75Hz over those standards. Three USB ports are included for peripheral pass-through. If your workflow requires a different port mix or a higher refresh rate, this model will not match that requirement.
