Dell UltraSharp 40" 2160p HDR 120 Hz Curved Thunderbolt Hub Monitor

Dell UltraSharp 40″ 2160p HDR 120 Hz Curved Thunderbolt Hub Monitor is engineered for creators and power users who demand uncompromised clarity, speed, and connectivity. Its expansive 39.7″ 5K2K (5120 × 2160) panel runs at a silky 120 Hz with VRR for smoother motion and reduced blur, while IPS Black technology elevates contrast to a class-leading 2000:1 for deeper blacks and richer detail. With TÜV Rheinland 5-Star Eye Comfort, an Ambient Light Sensor, and ComfortView Plus (<35% blue-light emission), you can work longer with less fatigue. Dual Thunderbolt™ 4 ports, integrated 2.5GbE, built-in KVM, and iMST (Internal Multi-Stream Transport) make this a full desktop hub that streamlines multi-device workflows—no external splitters or software required.
