The Dell P2421DC is a 23.8-inch monitor featuring a Quad HD 2560 x 1440 resolution on an IPS panel. It operates at a 60 Hz refresh rate with an 8 ms response time, suitable for standard office applications. The screen maintains a 16:9 aspect ratio, a typical contrast ratio of 1000:1, and a pixel density of 123 ppi for sharp text reproduction.
This display is configured for professional work, covering 99% of the sRGB colour space and rendering 16.78 million colours. Its IPS technology offers wide 178-degree horizontal and vertical viewing angles, maintaining image consistency from different perspectives. The flat screen has a matte, anti-glare surface that minimizes reflections from ambient light, which is practical for use in well-lit office environments.
Connectivity is streamlined via a USB-C port that supports video, data, and power delivery from a single cable. Additional inputs include one HDMI 1.4 port and two DisplayPort 1.2 ports. A built-in hub provides four USB-A downstream ports for peripherals. The stand allows for full ergonomic adjustment, including height, tilt, swivel, and a 90-degree pivot. It is also compatible with a 100 x 100 mm VESA mount for alternative setups.
