Dell P2421 is a 24.10-inch business monitor for desktop work, with a TFT LCD panel, IPS technology and a 16:10 aspect ratio. Its maximum resolution of 1920 × 1200 at 60 Hz provides a taller workspace for documents, spreadsheets and multiple open windows.
The display has typical brightness of 300 cd/m², a 1000:1 contrast ratio and 99% sRGB color gamut. Typical horizontal and vertical viewing angles are 178°. An anti-glare faceplate with 3H hard coating helps reduce reflections during everyday use.
Connect a computer or other equipment through DisplayPort 1.2, HDMI 1.4, DVI or VGA. The integrated USB hub has one USB 3.0 upstream port, two USB 3.0 downstream ports and two USB 2.0 downstream ports. The stand adjusts in height up to 130 mm, tilts, swivels and pivots to help position the screen. A 100 × 100 mm VESA interface supports compatible mounting arrangements.
