The ViewSonic Elite XG320U, with its 32-inch Ultra HD 144 Hz panel and HDMI 2.1 input, is the perfect companion for the new Xbox Series S/X and PS5 game consoles. But is HDR rendering really up to scratch?

An interesting brightness peak, but perfectible colorimetry
The ViewSonic Elite XG320U on the HDR test bench.
The HDR testing protocol used for this monitor is identical to the one we apply to televisions. We use a SpectralCal C6-2000 probe, a 4K Ultra HDR pattern generator and CalMAN Ultimate software to evaluate HDR image quality.

In HDR, the ViewSonic monitor performs very well. Apart from a small excess of brightness between 30 and 50%, the reference curve (in yellow) is perfectly respected up to 50% luminance, before the signal is smoothed to the maximum capabilities of the monitor. This behavior is healthy and helps retain all image detail in very bright areas. The peak brightness measured at 596 cd/m² is correct for a PC monitor, nothing more. If this makes it possible to display a good dynamic image, in absolute terms, it remains less good than what an Oled TV can offer with around 750 cd / m² (LG 48C1), and far from the best LCD televisions which exceed 1,500 cd/m² (Samsung Neo Qled QE65QN95A and Sony XR-75Z9J).
With a delta E greater than 3, the colors displayed cannot be considered faithful to those sent by the source. The delta E nevertheless remains below 5 and the colorimetric drift remains contained and generally acceptable.
A never-before-seen Rec.2020 cover

Rec.2020 color space coverage
The good surprise comes from the colorimetric coverage, since the ViewSonic monitor offers the luxury of covering 86% of the Rec.2020 colorimetric space. It thus surpasses the TCL 65C815 television, which displayed the widest Rec.2020 coverage ever measured in the laboratory. The Rec.2020 remains very little used, but the prowess is to be underlined. Regarding the DCI-P3 used by the cinema, the coverage exceeds 90% and allows the majority of the colors in this space to be displayed.
See you Monday, January 31 to discover the complete test of the ViewSonic Elite XG320U monitor.
All brightness and colorimetry measurements mentioned in this article were performed with a SpectraCal C6-HDR probe and CalMAN Ultimate software.
