Hardware.Info checked out the Asus ProArt PA32UC-K
A quote from the article:
The new Asus PA32UC-K has an average price of 2013 pounds / 2300 euros. This 32 inch 4K monitor has this hefty price tag for a reason; it is one of the first monitors on the market with finely meshed local dimming. By being able to independently control the brightness of different zones in the backlight, the monitor promises to deliver one of the best HDR experiences to date.Asus ProArt PA32UC-K Review
A big promise for PC monitors is still high dynamic range, hdr. A wider range of colours, more colour nuances, greater maximum brightness and higher contrast should take the display to a higher level when it is combined with suitable source material. Although we have already seen a number of hdr-capable monitors this year, the colour quality of those models does not equal that of a good hdr television. A wide colour range or more shades of colour are not the problem, the required maximum peak brightness and contrast are.
