EXPLAINED: Dell debuts first 120 hz ips black monitors | Rare Historical Photos

Dell UltraSharp U2724D and U2724DE.

Dell has announced a pair of new 27-inch monitors coming to its businesslike UltraSharp family. But these new cleanly styled monitors, the UltraSharp U2724D and U2724DE, also have a gamer-pleasing trick up their sleeves: they're the first monitors we know of featuring IPS Black display panels that run at 120 Hz refresh rates.

IPS Black display panels are actually made by Korea’s LG and were originally announced during CES 2022. As the name implies, the refined IPS technology offers deeper black reproduction, touted to be “a 35% deeper black than existing IPS products, doubling the contrast ratio.” Putting some numbers to that assertion, a typical IPS monitor contrast ratio would be approximately 1000:1, but IPS Black panels can do 2000:1. Moreover, LG says that IPS Black also offers improved viewing angles and bolsters color volume in low-gradation areas.
