Think about the work you do most often. Spreadsheets and side-by-side documents benefit from usable screen area, while photo work makes color consistency and viewing angles more important. Screen size and resolution should be considered together: a sharper display can show more detail, but text may appear small until you adjust scaling to suit your eyesight and software.
Ergonomics can matter as much as image quality. A stand with height, tilt, and swivel adjustment makes it easier to position the screen comfortably. Check whether the display supports a mounting standard if you plan to use an arm. Place the monitor so the top of the screen is near eye level and avoid reflections from windows or lamps.
Review the ports before choosing. USB-C may carry video, data, and power over one cable when both the monitor and computer support those functions, while HDMI and DisplayPort are common alternatives. Confirm the maximum resolution and refresh rate supported by your computer. A built-in USB hub can tidy a desk, but consider how it connects to the computer. Set brightness for the room and use a text size that remains comfortable through a full workday.
