Choosing a computer monitor: a practical buying guide for every workspace

A computer monitor may seem easy to choose at first. However, marketing terms, limited connectivity and the wrong dimensions can mean your screen no longer suits the way you use it after just a few months. A gaming monitor has different requirements from a screen for working from home, design or interactive use.

So don’t focus only on the price or the number of features. Consider the combination of screen size, resolution, panel type, refresh rate and connections.

Common pitfalls when choosing a computer monitor

1. A high refresh rate without a suitable connection

A monitor with a 180 Hz, 200 Hz or 240 Hz refresh rate can display smooth movement, but only if your computer, graphics card and cable support the rate you want. Check the version and capabilities of HDMI and DisplayPort. Some models need DisplayPort to reach their maximum refresh rate.

A high-refresh-rate monitor is especially relevant for fast-paced games. For word processing, admin and standard office work, 60 to 100 Hz is often sufficient.

2. A large screen with too low a resolution

A 27-inch monitor with Full HD offers plenty of screen space, but has fewer pixels per inch than a 24-inch monitor with the same resolution. Text and fine lines may therefore look less sharp when you sit close to the screen.

You could also consider a Quad HD or 4K monitor for a 27-inch screen. However, check that your computer can run the higher resolution smoothly. A 4K monitor isn’t automatically suitable for everyone: gaming may require a powerful graphics card.

3. Features you can’t actually use

As well as HDMI or DisplayPort, a touchscreen monitor usually needs a USB cable for its touch function. Without this connection, the picture will work, but touch controls may not. With a USB-C monitor, you should also check whether USB-C supports video, data and Power Delivery. Not every USB-C port can charge a laptop.

A VESA mount gives you more flexibility when positioning your monitor, but check the pattern, such as 75 × 75 mm or 100 × 100 mm, and the monitor’s weight before buying an arm or wall bracket.

Which specifications should you compare?

Screen size and resolution

  • 24-inch monitor: suitable for compact desks, office work and Full HD.
  • 27-inch monitor: offers more workspace and is popular for gaming and working from home.
  • 31.5 inches or larger: worth considering for multitasking, design and large spreadsheets.
  • Ultrawide monitor: a 21:9 screen can display several windows side by side without the need for a second monitor.

Full HD typically means 1920 × 1080 pixels. Quad HD uses, for example, 2560 × 1440 pixels, while 4K UHD uses 3840 × 2160 pixels. Don’t look at pixel count alone: consider your viewing distance and your operating system’s scaling settings too.

Panel type: IPS, VA or TN

An IPS monitor is known for its wide viewing angles and generally consistent colour reproduction. This makes it a good fit for office work, image editing and general use. VA panels often offer higher static contrast, which can enhance dark scenes in films and games. TN panels often have fast response times, but may have more limited viewing angles.

Specifications such as 1 ms or 5 ms aren’t always directly comparable. Manufacturers may use different measurement methods, such as GTG or MPRT. Treat response time as a guide, rather than the only factor in your decision.

Refresh rate, synchronisation and ergonomics

Refresh rate is measured in hertz. 60 Hz is common for productivity; 100 Hz, 144 Hz, 180 Hz, 200 Hz and 240 Hz are designed to deliver smoother movement. Adaptive Sync technology can help reduce screen tearing when your computer’s frame rate changes. Always check that your graphics card and connection are compatible.

For everyday use, an adjustable height, tilt function and, where available, swivel are more important than an extra picture mode. A monitor with a VESA mount gives you more choice of monitor arms and wall brackets. Also check the energy class and energy consumption per 1,000 hours, as your screen may be on for several hours each day.

Frequently asked questions about computer monitors

Is a 24-inch monitor suitable for working from home?

Yes. A 24-inch monitor takes up relatively little desk space and, with Full HD, provides enough room for text, email and spreadsheets. If you want to view several windows side by side, a 27-inch or ultrawide monitor may be more practical.

How long does a computer monitor last?

Its lifespan depends on how intensively it’s used, heat, transport and the quality of the power supply. Check the warranty terms when you buy and keep your receipt. In the EU, consumers are entitled to at least the statutory protection for goods to conform to their contract; the products mentioned typically come with a statutory warranty of at least two years. This is separate from any additional manufacturer terms.

Does a larger or faster monitor use more power?

It can, but power consumption varies by model. Check the energy class and stated consumption per 1,000 hours. A larger screen, higher brightness, HDR and a higher refresh rate can all affect energy use. Turn off your monitor or use sleep mode if you won’t be using your computer for a while.
