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.

Questions about this item

How do I attach the VX4381-4K to a monitor arm, and what step is often missed?

Remove the stand base and neck first, then fasten the arm bracket to the four threaded holes on the rear housing; the step often missed is detaching the neck before the base.

What maintenance or replacement will the VX4381-4K need over time?

The backlight and colour accuracy will drift slowly; run the built-in calibration routine periodically and clean the anti-glare coating with a microfibre cloth and water only.

Which limit appears first during long sessions on the VX4381-4K?

Sustained full-screen brightness at 450 cd/m² can trigger thermal throttling that dims the panel after several hours of continuous HDR10 content.
