Asus is consistently further developing the concept of local dimming, i.e. backlighting with many small LEDs, with the new Asus ProArt PA32UCX 4K Profi Monitor. The use of mini LEDs enables the first local dimming of 1,000 zones, which can have different background brightness and thus greatly increase the overall contrast of the screen. This is a significant improvement over monitors such as Asus ROG SWIFT PG27UQ or Acer ProDesigner Monitor BM270, which were launched half a year ago and only have 384 local dimming zones - more zones allow more accurate illumination and minimize the halo effect or "light bleeding" in bright areas.

At the same time, the use of mini LEDs enables the very high brightness of 1,200 nits, which far exceeds the requirements of the DisplayHDR 1,000 HDR standard. The 32" (around 81 cm) 10-bit display has an Ultra HD 4K resolution (3,840 x 2,160), supports several HDR formats such as HDR10 and HLG (Hybrid Log Gamma) and covers 97% of the PCI-D3 color space and 89% of the Rec.2020 color space. The Asus ProArt PA32UCX has two USB-C Thunderbolt 3 ports which can be used to connect several monitors in series or to power a notebook computer. Alternatively a computer can be connected via HDMI 2.0 or DisplayPort.
The development of mini LEDs as backlights acts like an intermediate step on the way from LCD to Micro LED Displays, as already presented by Samsung at the CES 2019: when, so to speak, out of the 1,000 zones of different backlighting by mini LEDs each pixel becomes its own (or three) light source (aka Micro LED) and the use of light-absorbing color filters (as with LCD) can be completely dispensed with. It is only a matter of time before this step is also taken in the area of monitors and becomes attractive in terms of price.
The qualities of the Asus ProArt PA32UCX display - the brightness as well as the colour gamut - also predestine it for use in video editing. Asus has not yet commented on the price of the ProArt PA32UCX - but it is expected to be launched in spring.
