Start with how you work and the space you have. Look for a comfortable size, an IPS panel for wide viewing angles, and solid connectivity such as HDMI, DisplayPort, and VGA for legacy devices. A built‑in USB hub and USB‑C charging help keep cables tidy and your laptop powered, reducing desk clutter. For example, a Dell 27‑inch office monitor offers USB-C (charging up to 15W) plus a USB hub, while a larger Dell variant ups the game with upstream USB‑C PD around higher power and multiple USB ports. A ThinkVision ultrawide option adds docking and Ethernet for richer multitasking.
