Dell has added a new display to its UltraSharp range and this time around we're looking at a 38-inch ultra-wide display with a resolution of 3840 x 1600 pixels. The display uses an IPS Black panel with a 2000:1 contrast ratio and it covers 100 percent of the sRGB and REC.709 colour gamuts, as well as 98 percent of the DCI-P3 and Display P3 colour gamuts. Sadly it only has a brightness of 300 cd/m² and it's unclear if this is an 8-bit + FRC or a true 10-bit panel, as Dell only mentions support for 1.07 billion colours. It uses a standard WLED backlight, so no fancy miniLED backlight here and as this display is intended for work use, it also only appears to support 60 Hz refresh rate with a response time of 8 ms in normal mode.

Other features include a built-in KVM switch courtesy of a pair of USB-C ports, with the primary supporting USB PD up to 90 W, as well as DP Alt mode, with the second port only supporting USB 3.2 Gen 2 data at up to 10 Gbps. Other inputs include two HDMI 2.1 ports and one DP 1.4, while the outputs consist of five USB 3.2 Gen 2 10 Gbps Type-A ports, two USB-C 3.2 Gen 2 10 Gbps ports, a 2.5 Gbps Ethernet jack and a 3.5 mm audio line out jack. One interesting feature is that the built in Ethernet supports network boot, something that isn't a common feature on monitors and it also has the ability to lock the wired port to one of the two connected computers in KVM mode. The stand supports height,swivel and tilt adjustment. The asking price for the U3824DW is US$1,529.99 and it's available from Dell now.
 
In my opinion far too expensive versus OLED monitors.
