Quick answer: For most office work a 24"–27" Full HD or QHD monitor is ideal — and a dual-monitor setup can boost productivity noticeably.
Size and resolution
- 24" Full HD: the affordable office standard
- 27" QHD: more screen space for multitasking
- Ultrawide: great for finance, design and trading desks
Why dual monitors?
Two screens reduce window-switching and speed up workflows for admin, finance and support roles — often the cheapest productivity upgrade you can make.
Don't forget ergonomics
- Height-adjustable stands or monitor arms
- Eye-care features (flicker-free, low blue light)
- The right connectors (HDMI, DisplayPort, USB-C)
