IPS monitors usually ship with a 1,000:1 contrast ratio, but Dell is launching the first monitors in the world to use IPS Black technology to double that to 2000:1.
As Tom's Hardware reports, both the Dell UltraSharp U2723QE and the UltraSharp U3223QE incorporate LG's IPS Black technology, which was announced last year. However, not even LG has shipped a monitor using it yet (they are expected later this year). Dell beats it to market this month with these new 27-inch and 31.5-inch UltraSharp models.
The main advantage of IPS Black, as the name suggests, is greatly improved, deeper blacks combined with wide viewing angles of 178 degrees. Dell says both these 4K monitors achieve 98% of the DCI-P3 RGB color space, offer 1.07 billion colors, 400 nits of brightness, low blue light output, and support VESA DisplayHDR 400. For connectivity, you get HDMI, DisplayPort, and USB-C. The one thing that's missing is a high refresh rate required for gaming, with both monitors limited to 60Hz.
World's first tech usually carries with it a premium price, and these UltraSharp monitors are no exception. The 27-inch U2723QE costs $779.99, while the 31.5-inch U3223QE costs $1,149.99. It's possible to daisy-chain two of these displays together using USB-C, which is sure to be a popular, albeit expensive, temptation to order a couple.
