ASUS PA32UC UHD HDR model with 384 dimming zones
We’ve covered a broad range of ‘4K’ UHD monitors. All things considered, we feel ~32” is something of an optimal size for the resolution, combining strong pixel density with good scaling-free readability. The ASUS PA32UC of the ProArt series employs a screen of this size and resolution. It is put together in quite an elegant-looking package, with a fairly similar aesthetic to the 27” PA27AC. The stand appears to use brushed metal lower down and a different texture higher up, separated by a golden ring. The screen itself appears quite angular, with fairly thin bezels. These appear to be single-stage with a hard bezel covering the panel border. This contrasts with the ‘seamless’ dual-bezel design of the 27” variant, likely due to the advanced backlight solution housed within.
The monitor uses a 32” IPS-type (In-Plane Switching type) panel with 3840 x 2160 (‘4K’ UHD) resolution, 60Hz refresh rate and 178° horizontal and vertical viewing angles. Adaptive-Sync is also supported for AMD FreeSync compatability with certain AMD GPUs and systems, with a variable refresh rate range of 40 – 60Hz (and possibly 29 – 65Hz via HDMI, TBC). The screen surface is matte anti-glare (likely a light matte solution). A static contrast ratio of 1000:1 is specified, although that is likely just during normal SDR operation. The monitor supports HDR (High Dynamic Range), with a flicker-free backlight that is split into 384 independently controlled dimming zones. The rated peak luminance of 1000 cd/m² reflects the ability of these zones to pulse to extreme brightness levels, a useful part of the bigger HDR picture. 10-bit colour is supported (possibly 8-bit + FRC dithering) which is also an important consideration for HDR, whilst a colour gamut of ‘over 95% DCI-P3’, 85% Rec. 2020 and 99.5% Adobe RGB is specified. This will work well for HDR-10 that will target DCI-P3 as the colour gamut of choice currently. The monitor comes factory calibrated with an average DeltaE <2. Hardware calibration is also supported with compatible colorimeters (‘ASUS ProArt Calibration Technology’). A 5ms grey to grey response time is specified, whilst 6-axis colour adjustment (RGB + CMY) and 5 gamma settings are included alongside Low Blue Light settings.
The included stand offers full ergonomic flexibility and can be detached using a quick-release button, to make way for an alternative 100 x 100mm VESA solution if preferred. Ports include; 2 Thunderbolt 3 compatible USB-C ports (input + output), HDMI 2.0b, DP 1.2, 2 USB 3.0 ports (Type A) and a 3.5mm headphone jack. Two 3W speakers are also included for basic sound output. PiP and PbP is supported, with up to 4 independent sources for Picture by Picture. Further information can be found on the manufacturer’s website. Information on pricing and availability is still forthcoming. We’ll consider reviewing this model if there is good demand for it.
