TUV Rheinland officially certifies IPS Black technology. Dell is the first to launch monitors with this technology.
Some of the key advantages of this technology are:
The key advantage is a wider viewing angle of 178 degrees, revealing accurate colors even when viewed from the side. Improved color contrast ratio at all ranges of viewing angles enables content on the screen is the same from any angle. This feature is especially essential for users that have a dual or multi monitor setup. It is helpful while viewing detailed graphs or charts such as stock-related content. In addition, it supports your collaboration with others, as all people around the monitor can see the same screen while standing next to you around.

IPS Black technology is well suited for designers for its representation of deep blacks and color accuracy. As it expresses deeper black and vivid colors in 4K clarity, professionals can work with wide range of colors that are true-to-life. In addition, they can experience the same level of color accuracy in low gray colors even at the side of the monitors. It helps with professional design applications that are designed in low gray content, with support for 98 percent of DCI-P3 color gamut.
IPS Black technology is used to achieve a 2,000:1 contrast ratio, enabling detailed low gray expression. This feature helps to work with detailed digital images or graphic arts for games.
IPS Black technology provides 35% deeper black than conventional IPS, so that it enables sharper expression. At the same white luminance of 400nit, the black luminance of conventional IPS and IPS black (> 2,000:1) varies by approximately 0.1 nit. IPS black can express deeper black by minimizing light leakage changing liquid crystal and improving liquid crystal array.
IPS Black technology is officially certified as a premium IPS panel by TUV Rheinland. This includes a wide viewing angle, higher contrast ratio, rich color volume, and low blue light technology applied.
|Required Spec.||Testing Criteria||Spec (Test Result)|
|CR||Checkerboard Contrast||>= 2000:1|
|Color||Color Gamut||>=DCI 98%|
|Low blue light||Low blue light||Pass|
|Viewing Angle||CR Consistency||>= 50%|
|Color Accuracy||<= 0.02|
|Gamma Shift Ratio||<= 5%|
It has over 2000:1 CR, DCI 98%, and low blue light. The Gamma Shift Ratio (GSR) of viewing angle spec is under 5%, whereas GSR of VA is around 10%.
