Buying a computer monitor: how to choose a screen that suits the way you use it

Buying a computer monitor seems straightforward until you start comparing specifications. A low price, high refresh rate or large screen may sound appealing, but it does not always tell you enough about practical usability. Three common pitfalls are:

  • A high refresh rate without a suitable connection: a monitor with 144 Hz or more needs a computer and cable that can actually deliver this signal.
  • A large screen with too low a resolution: on a 27-inch monitor, Full HD may look less sharp than on a 24-inch model. With ultrawide screens, the combination of size and resolution is even more important.
  • Lots of features, but limited ergonomics: a built-in hub or HDR support is no substitute for a stand that can only tilt if you spend several hours in front of the screen every day.

The right choice therefore depends on your workspace, computer, viewing distance and intended use. Below are the main points to consider before buying a monitor.

The most important specifications when buying a monitor

1. Screen size and resolution

A Full HD monitor with 1920 × 1080 pixels is suitable for basic use, administration, browsing and streaming. A 24-inch computer screen is a practical combination: text generally remains easy to read without taking up too much desk space.

A 27-inch monitor offers more workspace. For this size, QHD at 2560 × 1440 pixels is often a sensible middle ground. You get more room for windows and text than with Full HD, without immediately taking on the higher demands of 4K.

A 4K monitor displays 3840 × 2160 pixels. This can be useful for photo editing, detailed spreadsheets and entertainment. However, check that your computer can output the desired resolution and refresh rate via HDMI or DisplayPort.

With an ultrawide monitor, the aspect ratio and desk depth also matter. A 34-inch screen with a 21:9 aspect ratio is suitable for placing two windows side by side. A 49-inch model with a 32:9 aspect ratio takes up considerably more space and requires a sturdy, deep desk.

2. Refresh rate and response time

Refresh rate is expressed in hertz. 60 or 75 Hz is sufficient for word processing and general office work. 100 or 120 Hz makes scrolling and movement smoother. For a gaming monitor, refresh rates of 144 Hz, 175 Hz, 180 Hz or 240 Hz are relevant, particularly for fast-paced games.

Bear in mind that a stated maximum is not automatically available in every situation. The port, cable, resolution and graphics card used together determine what is achievable. Also check the difference between GtG and MPRT when looking at response times: these are different measurement methods, so the figures are not directly comparable.

Variable sync technology, such as FreeSync, can help reduce screen tearing when the refresh rates of the screen and graphics card fall out of sync. Check compatibility with your system. Do not assume a monitor is “G-Sync Compatible” unless this is officially stated in the product specifications.

3. Connections and ergonomics

Do not just look at the number of ports; consider what they are used for too:

  • HDMI: suitable for PCs, laptops, consoles and media players.
  • DisplayPort: often practical for high refresh rates and PC gaming.
  • USB-C: on suitable models, this can combine video, data and power.
  • USB hub: useful for a mouse, keyboard or other accessories.
  • VESA mounting: allows you to mount the monitor on a monitor arm or wall bracket.

A USB-C monitor is particularly useful with laptops. Check whether the port only transmits video or also supports Power Delivery. For example, the Dell Pro Plus P2725DE specifies USB-C with up to 90 W Power Delivery and an RJ45 connection. This can make your desk tidier with a single cable, but only if your laptop supports the relevant USB-C functions.

For a monitor for working from home or in the office, height adjustment, swivelling, tilting and pivot are often more important than HDR. Position the top edge of the screen roughly at eye level and place the computer screen at a suitable viewing distance. A monitor arm can be useful if the supplied stand offers too few adjustment options.

Frequently asked questions about buying a computer screen

Is 27 inches with Full HD sufficient?

That depends on your viewing distance and preference for text sharpness. For a 27-inch monitor, QHD can provide more workspace and a finer pixel structure. Full HD remains suitable for general use, but compare the pixel density if you read a lot of text.

How much does a monitor typically cost to run?

Power consumption varies according to size, brightness, resolution and panel type. Check the stated power consumption and the information on the European energy label. A 20 W model uses less energy than a 60 W model over the same period of use, but the actual cost depends on your electricity tariff and number of hours of use.

How long does a PC monitor last?

Lifespan varies according to the brand, model and conditions of use. Position the screen securely, keep the ventilation openings clear and use a soft, dry cloth to clean the display. Check the warranty terms when buying and keep your purchase information. In the EU, consumers are covered by statutory conformity rights; any additional manufacturer’s warranty may vary by product.
