Professional 4K monitor

The Dell UP3221Q is a 31.5 inch IPS display with a 3840 x 2160 resolution and 1.07 billion colour support. It targets creative professionals who need accurate colour reproduction and high pixel density for detailed imaging work. The 16:9 aspect ratio and 60 Hz refresh rate suit standard desktop and content-creation workflows.

Connectivity and ergonomics

Two HDMI 2.0 ports, one DisplayPort 1.4 connection and dual Thunderbolt 3 ports with DP 1.4 alternate mode provide flexible video and data routing. Two SuperSpeed USB 10 Gbps downstream ports simplify peripheral attachment. The stand delivers height, pivot, swivel and tilt adjustments so the screen can be positioned for long editing sessions.

HDR brightness upgrade

Typical SDR brightness reaches 350 cd/m2 while HDR peaks at 1000 cd/m2 with a 1,000,000:1 contrast ratio when HDR is active. This jump from standard 350 cd/m2 panels is worthwhile for colour-critical HDR grading and bright-room viewing. Buyers who need higher refresh rates for competitive gaming or larger screen diagonals for multi-monitor walls should look elsewhere.
