HP revealed a 31.5-inch monitor geared for professionals with high-resolution and image-quality requirements at its Amplify partner conference on Thursday,

The HP Z32k G3 with 4K resolution promises to be the first display to feature IPS Black technology and a Thunderbolt 4 USB-C connector.

Dell was the first company to deploy IPS Black, incorporating LG’s technology into 27-inch and 31.5-inch USB-C UltraSharp displays. IPS Black is a type of IPS panel designed to produce deeper black levels and thereby twice the standard IPS contrast ratio.

LG claims that the black levels in IPS Black are 35 percent deeper than other IPS devices.

IPS Black versus Mini LED and OLED

HP’s Z32k G3 boasts a 2000:1 contrast ratio, higher than the ordinary IPS monitor’s 1.000:1 and premium IPS ratio of roughly 1300:1. Assuming HP’s claims are true, it’s worth mentioning that the ratio doesn’t equal the contrast provided by displays with more costly backlighting technologies, including Mini LED or OLED.

ArsTechnica reviewers tested the IPS Black on the Dell UltraSharp U2723QE. They noticed contrast ratios up to 1977:1 with contrast settings maxed out, making tiny black writing on white backgrounds harder to see, although dark hues and brighter details shone through more powerfully.

How the monitor is expected to perform

Even with the default contrast settings, the panel achieved a contrast ratio of 1873:1 and displayed a visual quality that was notably more vivid than a standard IPS monitor. HP’s Z32k G3 is anticipated to feature the same 31.5-inch IPS Black screen as Dell’s UltraSharp U3223QE.

HP’s display boasts up to 400 nits of brightness and is VESA DisplayHDR 400 certified. It should also cover 98 percent of DCI-P3 with a Delta E of less than 2, making color errors invisible to the human eye. HP also said its IPS Black display will provide more realistic colors at lower light levels than standard IPS panels.
