Further information on supporting our work.The pixel density, workspace and detail potential offered by ~32″ ‘4K’ UHD screens is very enticing. The ViewSonic VX3220-4K-PRO combines this with a high refresh rate support for HDMI 2.1. Allowing this high refresh rate experience to be enjoyed by not just PC users, but with 120Hz support for the PS5 and Xbox Series X as well. The monitor offers the usual simple styling of the VX series, with a ‘penguin foot’ stand base and extensive use of matte black plastic. The top and side bezels are dual-stage, with a slender panel border flush with the rest of the screen and a slim hard plastic outer part. The OSD (On Screen Display) is controlled by buttons at the rear of the screen, running down the right side as viewed from the front.

A 31.5″ 3840 x 2160 (‘4K’ UHD) IPS-type panel is employed, believed to be an Innolux AAS (Azimuthal Anchoring Switch) panel. This is coupled with a maximum 150Hz refresh rate (144Hz + mild factory overclock). Adaptive-Sync is also supported, including AMD FreeSync with a 48 – 150Hz VRR range plus LFC. Other aspects of note include a light to very light matte anti-glare screen surface, 1000:1 static contrast ratio, 178°/178° viewing angles and 10-bit (8-bit + FRC) colour support. The monitor is factory calibrated with a specified DeltaE <2, whilst a flicker-free WLED backlight delivers a colour gamut of 83% Adobe RGB and a 350 cd/m² typical maximum luminance. 90% DCI-P3 should usually specified for similar models and we'd expect this to be achieved here. VESA DisplayHDR 400 support is included, allowing the monitor to respond to HDR10 content. Putting its colour gamut and 10-bit colour support to good use, whilst allowing a 400 cd/m²+ peak luminance to be delivered. This HDR tier does not require local dimming and this isn't specifically mentioned for this model, although based on the panel we believe is used, 16 dimming zones may be included for a situational boost in contrast.
Low Blue Light (LBL) settings are included to promote more relaxing viewing. A 1ms response time is specified, which should be approached with caution as usual. The stand attaches centrally via a quick-release mechanism and can be removed to make way for an alternative 100 x 100mm VESA compatible solution if preferred. The included stand offers full ergonomic flexibility, including 140mm (5.12 inches) height adjustment and pivot into portrait. The ports face downwards and include; DC power input (external ‘power brick’), 2 DP 1.4 ports, 2 HDMI 2.1 ports, USB-C (DP Alt Mode, 65W PD, upstream data), a 3.5mm headphone jack and 2 USB 3.0 ports plus upstream. 2 x 2W speakers are also included, for basic sound output. PiP and PbP functionality is supported, too.
Further details can be found on some regional product pages from the manufacturer, including their Chinese page (requires English translation). Details on price and availability in markets such as the US and UK still to come.
