ViewSonic XG3220 4K UHD VA model with HDR10 support
~32” is something we consider to be a good size for a ‘4K’ UHD screen. A high enough pixel density to bring a good ‘4K’ feel to the experience, but not so high that scaling is a must for all users. There are a number of models now on the market which make use of 31.5” VA panels with this resolution, such as the AOC U3277PWQU and Samsung U32H850. The ViewSonic XG3220 adopts such a panel and applies a style quite familiar amongst their ‘XG’ series of gaming monitors. The monitor is mainly matte black plastic, with a few dark red elements such as the cable-tidy loop in the centre of the stand neck and the menu labels running down the right bezel. The bezels are fairly slender and are a single-stage design, with matte black plastic covering pretty much the entire panel border. The OSD (On Screen Display) is controlled by pressable buttons at the rear of the monitor, along the right side as viewed from the front.
A 31.5” VA (Vertical Alignment) panel is used, specifically an AAS (Azimuthal Anchoring Switch) panel from InnoLux. This has a 3840 x 2160 (‘4K’ UHD) resolution, with a specified 3000:1 static contrast ratio and 178°/178° viewing angles. The monitor has a 60Hz refresh rate and supports AMD FreeSync via HDMI 2.0 and DP 1.2a, with a variable refresh rate range of 40 – 60Hz. A light matte anti-glare screen surface is employed and 10-bit colour is supported (8-bit + FRC dithering). The monitor features a flicker-free WLED backlight with 300 cd/m² typical maximum luminance. We know these panels tend to offer a wide colour gamut and for this model a 95% NTSC gamut is mentioned. Provide it is properly controlled, this can prove useful for HDR10 content, which this monitor supports. There is no mention of local dimming, so we expect this to be more of an HDR emulation than anything. But at least the colour gamut should come pretty close to the near-term HDR target of DCI-P3.
ViewSonic specifies a typical grey to grey response time of 5ms, although users should be aware of the significant variation for VA panels like this depending on the transitions involved. It will also depend on the level of pixel overdrive used. This model offers good flexibility in that respect, with ‘Rampage Response Time’ settings offering 5 levels of acceleration. The monitor also includes a ‘Low Input Lag’ through mode which bypasses extraneous processing to minimise latency. The rear of the monitor has a few red ‘XG’ branding elements, but is mainly black matte or ‘vinyl effect’ plastic. The included stand attaches centrally and can be removed to make way for 100 x 100mm VESA mounting. The stand offers a full range of ergonomic adjustment; tilt, height, swivel and pivot (90° clockwise rotation into portrait). The ports are down-firing and include; 2 HDMI 2.0 ports, DP 1.2a, 3.5mm headphone jack, 2 USB 3.0 ports (plus upstream) and a DC power input (external ‘power brick’). 2 x 5W speakers and a retractable headphone hook are included alongside a K-Slot, for good measure.
Further information can be found on the manufacturer’s website. Information on price and release date still forthcoming, we’ll look to review this model if there’s enough interest from users.
