One more monitor will be released by Dell on the short term. The U2415 will feature similar styling to the existing U2414H model, but will revert to a 16:10 aspect ratio with 1920 x 1200 resolution. Some people still prefer this aspect ratio for work, given it has a little more vertical room than the wide range of 1920 x 1080 models out there.
The panel is a 24" AH-IPS panel with 1920 x 1200 resolution, 6 - 8ms G2G response time (there are two overdrive modes on this model), 1000:1 contrast ratio, 50 - 300 cd/m2 brightness and 178/178 viewing angles. Unlike the previous 16:10 aspect 24" model, the U2413, the new U2415 will feature a standard sRGB colour space from its W-LED backlight and 16.7m colour depth. The screen does come factory calibrated with a dE of <3 specified. Where the U2413 was an update to the U2410 (both wide gamut, colour professional models) this model looks more like an update to the U2412M (standard gamut, more main-stream).
Dell have gone for an ultra-slim bezel design as well, measuring apparently only 6.9mm including the panel border. The stand offers a full range of tilt, height, swivel and rotate adjustments. Connectivity wise there are 2x HDMI (with MHL), DisplayPort, Mini DisplayPort, DisplayPort Out (for Daisy Chaining), audio in, audio out and a 5 port USB 3.0 hub. One USB port features fast charging capability also. The user guide for the screen lists an "analogue backlight dimming control for flicker free display" as well, so seems like Dell have now adopted the flicker free approach officially as well.
At the moment the U2415 is listed on dell's China website for 3299 Chinese Yuan, which is around £323.50 or $537 USD. No word on release date yet or official UK/US pricing.
