Buying a computer monitor: how to choose a screen without regretting your purchase

Buying a computer monitor might seem straightforward, until you find that your screen doesn’t have enough ports, text looks grainy or your laptop can’t charge while connected. Marketing terms such as “gaming”, “HDR” and “4K” don’t always tell you how well a monitor will suit your workspace, either.

So look out for these common pitfalls:

  • High resolution without a suitable screen size: on a small screen, 4K menus and text can look too small. On a large Full HD screen, pixels may be clearly visible.
  • High refresh rate without a suitable connection: 120 or 144 Hz will only work if your computer, cable and selected input support that speed.
  • Assuming USB-C is a universal cable: not every USB-C port carries a video signal or charges a laptop. Check specifically for DisplayPort Alt Mode and the power output of the Power Delivery feature.
  • Underestimating the importance of the stand: a monitor that isn’t height-adjustable may be less comfortable during a long working day. A VESA mount gives you extra flexibility with a monitor arm.

The most important specifications for a PC monitor

1. Size and resolution

For everyday office work, a 24-inch Full HD monitor is often a practical choice. The 1920 × 1080 resolution works well for documents, browser windows and video calls. An IPS monitor also offers wide viewing angles and generally consistent colours.

A 27-inch monitor gives you more workspace. At this size, Quad HD, such as 2560 × 1440, is often a good middle ground. The ASUS ProArt PA278CV, for example, has a 27-inch IPS screen with 2560 × 1440 pixels and 109 ppi. For photos, illustrations and other creative work, the product information also lists 100% sRGB and factory calibration with Delta E <2.

If you want to use several windows side by side, consider an ultrawide monitor. 34-inch screens with 3440 × 1440 pixels have a 21:9 aspect ratio. Just make sure your desk is wide enough and that your laptop or graphics card supports the resolution.

2. Refresh rate and response time

A refresh rate of 60 Hz is sufficient for word processing and most office tasks. 100, 120 or 144 Hz makes scrolling and movement look smoother. For a gaming monitor, support for Adaptive-Sync or FreeSync is also worth considering.

Be aware of the difference between refresh rate and response time. 144 Hz indicates how many frames can be displayed per second; a response time of, for example, 4 or 5 ms indicates how quickly pixels can change colour according to the manufacturer’s testing method. These figures aren’t directly comparable between brands.

3. Connections, ergonomics and energy use

Before buying, check:

  • HDMI and DisplayPort: check the version and the supported resolution and refresh rate.
  • USB-C: check whether the port supports video and Power Delivery.
  • Power output: a USB-C monitor with 90 or 100 W can charge compatible laptops; lower figures may not be enough for every model.
  • Ergonomics: height adjustment, tilt, swivel and pivot help you position the screen to suit your posture.
  • VESA: useful for a monitor arm or wall mount. Check the mounting pattern, for example 100 × 100 mm or 75 × 75 mm.
  • Power consumption: compare the stated typical consumption and energy rating. A higher refresh rate or HDR mode can affect power use.

Frequently asked questions about buying a computer monitor

Which monitor is suitable for working from home?

For working from home, an IPS panel, at least Full HD resolution, an adjustable stand and enough connections are good practical starting points. If you often work with two windows open, consider a 27-inch Quad HD monitor or an ultrawide monitor. USB-C with Power Delivery is handy if you want to connect a laptop with a single cable.

Is 4K worth the extra cost?

It depends on the screen size, what you do and the computer you use. A 4K monitor is especially useful for fine detail, photo and video editing, and having plenty of workspace. For simple documents, Full HD may be enough. Also check the scaling settings in Windows or macOS so that text remains easy to read.

How long does a monitor typically last?

A monitor’s lifespan depends on how it’s used, heat, transport and the quality of its power supply. Place the screen on a stable surface, keep the ventilation openings clear and use suitable cables.
