Some users seek an engaging HDR experience – something few monitors truly deliver. The ViewSonic XG321UG follows in the footsteps of the ASUS PG32UQX, with a focus on ‘4K’ immersion and the HDR experience. The monitor offers the usual ELITE series styling, with a low-profile coated metal and matte black plastic stand base and broad matte black plastic neck. 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 component. The bottom bezel includes downwards-facing ‘ELITE RGB’ LEDs, customisable in the OSD or using software. The OSD (On Screen Display) controls take the form of a downwards-facing joystick in the centre of the bottom bezel.

A stealthy appearance

The monitor employs a 32″ IPS-type panel – an AUO AHVA panel, more specifically. This has a 3840 x 2160 (‘4K’ UHD) resolution and supports a 150Hz refresh rate (144Hz + mild factory overclock). Alongside Nvidia G-SYNC Ultimate VRR support, with a G-SYNC module offering benefits such as variable overdrive and seamless operation over a broad VRR range. Other aspects to note include a light to very light matte anti-glare screen surface, 1000:1 static contrast ratio and 178°/178° viewing angles. True 10-bit colour is supported, whilst a flicker-free Quantum Dot Mini LED backlight is used. This provides a typical maximum luminance of 400 cd/m² and 98% DCI-P3 (99% Adobe RGB) colour gamut coverage. The backlight really shines (quite literally) for HDR10 content, with VESA DisplayHDR 1400 support offered. The Mini LED backlight solution used offers 1024 dimming zones 1152 dimming zones with a specified 1400 cd/m² peak luminance, for a very dynamic experience. The generous colour gamut and 10-bit colour processing can also be put to good use.

A 3ms grey to grey response time is specified, but don’t put too much weight on this. The stand offers tilt, swivel and height (120mm or 4.72 inches) adjustment. The screen attaches using a quick-release mechanism – removing it reveals 100 x 100mm VESA holes of alternative mounting. Additional ‘ELITE RGB’ LEDs form a hexagon around the stand attachment point. The ports face downwards and include; DC power input (external ‘power brick’), 3 HDMI 2.0 ports, DP 1.4, 3 USB 3.0 ports (plus upstream and a 3.5mm headphone jack. 2 x 5W speakers are included for potentially reasonably powerful sound output.
