OLED is an exciting technology, which has made its way onto various pieces of technology. Including TVs, smartphones and laptops. Aside from extremely high-priced and specialised displays or now discontinued low-production products, it hasn’t made its way into monitors. The ASUS PQ22UC of the ProArt series is a monitor with some head-turning specs but a compact (and portable) design. The screen can be latched onto an included stand, for desktop usage, or folded back with a ‘photo-frame’ style design. So the bottom sits fairly flush with the desk. The bezels are moderately thick, with a brushed textured matte black (or dark grey) plastic used. The OSD (On Screen Display) is controlled by pressable buttons running down the left side of the screen, giving accessibility with the monitor setup either with its photo-frame design or using the desktop stand.
The panel used is a 21.6” OLED (Organic Light Emitting Diode) part, manufactured by JOLED (Japan OLED) – a joint venture between Panasonic and Sony’s OLED display divisions. The monitor has a 3840 x 2160 (‘4K’ UHD) resolution, which on a screen of this size yields a very impressive pixel density of 204 PPI (Pixels Per Inch). With each pixel being its own light source, contrast is significantly stronger than any LCD panel – with a static contrast specified at 1m:1. So 1000x that of your average LCD. Multiple HDR formats are supported (HDR10 and HLG – Hybrid Log Gamma), with the monitor offering 99% DCI-P3 coverage and needless to say exceptional contrast. The peak luminance is 330 cd/m², so not particularly high for HDR but as expected for current OLED technology. The monitor is factory calibrated with a promised average DeltaE of <2, whilst 10-bit colour is supported with a 14-bit internal LUT. A guaranteed uniformity spec of 95% also applies, with hardware calibration supported via ASUS ProArt Calibration software and a compatible colorimeter (i1Display Pro and Spyder5 included). Colour space presets include sRGB, Adobe RGB, DCI-P3 and Rec. 2020. A 60Hz refresh rate is supported and a 0.1ms grey to grey response time is specified.
The inputs include 2 USB-C ports and Micro HDMI – in keeping with the compact design. Note that Micro HDMI can be connected to a standard HDMI port using a simple cable. The only ergonomic flexibility of the included stand is tilt and VESA mounting does not appear to be supported. With the desktop stand the monitor weighs 2.1kg (1.5kg screen only). The monitor saw a limited release in April 2019, with an RRP of £4,799. This is clearly not designed as a mass-produced product designed for mass appeal. It’s still a nice taste of the technology; note that JOLED plans to expand their OLED monitor panel production significantly from 2020.
