A monitor is the one accessory you stare at all day, and it is the one most people choose badly — too small, too dim, or the wrong panel for the work they do. Here is how to choose, and three picks that cover most home offices.
Size and resolution: the two decisions that matter most
For a desk, 27 inches is the sweet spot for most people: big enough for two windows side by side, small enough to fit. At 27 inches, get a 1440p (QHD) panel at minimum — 1080p at that size looks soft. A 27-inch 4K monitor is sharper still and worth it if you read small text all day, but the price jumps. A 24-inch 1080p screen is fine for a second monitor or a tight desk, but as your only screen it will feel cramped within a year.
Panel type and ergonomics
IPS panels have the best colours and viewing angles for office work; avoid cheap TN panels, which wash out the moment you move your head. Brightness of 250–350 nits is enough indoors. More important than any spec is the stand: height adjustment and tilt are essential — a monitor stuck at the wrong height causes neck pain within weeks. If the stand is fixed, budget for a monitor arm or a riser.
Three picks for 2026
Best all-rounder — Dell S2721QS 27″ 4K. A sharp IPS panel, good colours out of the box, and a stand that adjusts for height and tilt. The right choice if you want one monitor that does everything and lasts years.
Best budget — a 24″ 1080p IPS monitor from a major brand. For a second screen, a child’s desk, or a tight budget, a basic 24-inch IPS display from Dell, HP or Lenovo does the job well. Spend the savings on a monitor arm so the height is right.
Best for side-by-side work — a 34″ ultrawide (3440×1440). One wide screen replaces two monitors with no bezel in the middle, which suits spreadsheets, timelines and research. Make sure your desk is deep enough — an ultrawide at arm’s length is too close.
Before you buy
Check the ports: your laptop or PC needs an HDMI or DisplayPort output to match, and older laptops may need a USB-C to DisplayPort adapter. Check the return policy too — a monitor is the one purchase where dead pixels and backlight bleed are real risks, and a good return window is worth more than a small discount. Prices change often, so compare the current price on the day you buy.
