ASUS Reveals ProART PA32UCX 4K Monitor with 1,000-zone FALD Backlight

High-quality HDR gaming is rare on PC, with OLED PC displays being almost non-existent while Full-Array Local-Dimming (FALD) backlights remained rare, especially models with large numbers of local dimming zones.  

ASUS plans to change that with their MicroLED ProART PA32UCX, a 32-inch 4K monitor which uses “Mini LEDs” to offer a premium HDR experience with 1,200 nits of peak brightness, a backlight with 1,000 separate lighting zones and support for multiple HDR standards.   

When compared to Nvidia’s G-Sync HDR/G-Sync Ultimate Monitors, which boast 384-zone FALD backlights, ASUS’ ProART PA32UCX supports more accurate image reproduction with greater contrast ratios, with ASUS also boasting superior colour uniformity to an OLED panel. 

As a Pro-Grade monitor, the ProART PC32UCX supports more than HDR, reproducing 97% of the DCI-P3 colour space, 89% of the Rec. 2020 colour space and exceeds VESA’s DisplayHDR 1000 specifications. This monitor also supports Thunderbolt 3, HDMI 2.0 and DisplayPort inputs.   


     The very best LED-backlit LCDs employ a technology called full-array local dimming to improve their contrast ratios. The LEDs are arranged in zones, with each zone corresponding to part of the screen, and dimming individual LEDs makes it possible to display an image with bright and dark areas while preserving detail in both.

Our ProArt PA32UCX expounds on this technology with Mini LEDs. These physically smaller LEDs are packed in more densely, which increases the granularity of our brightness control. Less space between the LEDs means small details, like a white cursor on a black background, can be illuminated more precisely. The halo effect that’s common with coarser LED arrays normally manifests as light bleed around bright points, but that’s minimized when there’s a higher number of smaller LEDs.

The ProArt PA32UCX packs 1,000 zones into its 32” form factor, compared to other monitors that use 384 local dimming zones. This is no small achievement, and we had to work closely with the panel and scaler manufacturers on a custom design for controlling all those lighting zones. This technology didn’t exist before, and it took months of testing different proposed solutions before it could be perfected. As a result, the PA32UCX is one-of-a-kind. It offers 1,200 nits of luminance and offers improved whiteness and color uniformity compared to larger OLED panels.

ASUS has not revealed the pricing or release date of their new ProART PC32UCX 4K HDR monitor, though it is expected to release in the first half of 2019.
