Multi-PC workflow with integrated KVM
This monitor includes a built-in KVM switch that lets you control two PCs with one keyboard and mouse. Switching between systems is instant, so you keep momentum during complex tasks. Because the USB-C upstream also carries video, data and power, you can connect a laptop with a single cable. In practice, this reduces cable clutter and speeds up your daily routine.
Crisp 4K IPS panel for detailed work
The 43-inch IPS panel delivers 3840 x 2160 resolution with wide 178° viewing angles and 1.07 billion colours. Colour coverage hits 95% of the sRGB gamut for consistent results across design and admin work. An anti-glare coating cuts reflections, and the 350 cd/m² brightness handles bright offices. You get sharp text and clear visuals for spreadsheets, CAD and video review.
USB-C hub with 90 W power delivery
We like the integrated USB 3.2 Gen 2 hub for day-to-day efficiency. The USB-C upstream port provides up to 90 W charging, so a compatible laptop stays powered without a separate PSU. Four USB-A ports and one USB-C downstream port handle peripherals, plus there is a headphone jack for quick audio access. A wired Ethernet RJ-45 port is included for stable network connectivity.
Smart ergonomics and cable management
Adjust the height by up to 6 cm, and tilt the screen from -5° to 10° to suit your posture. The swivel range of -20° to 20° lets you share the display with a colleague when needed. Cable routing through the stand keeps the desk tidy, and the VESA mount supports 100 x 100 mm or 200 x 200 mm brackets. A cable lock slot helps secure the display in shared spaces.
Practical connectivity and display options
You get two HDMI 2.1 ports and two DisplayPort 1.4 inputs for flexible hook-ups. USB-C with DisplayPort Alt Mode handles video and data over one cable, while USB Power Delivery charges your laptop. The monitor supports a range of resolutions, including 1920 x 1080 and 3840 x 2160, for broad compatibility. OnScreen Display controls and Dell Display Manager simplify setup and screen layout.
