Choosing a gaming monitor: how to compare size, speed and picture quality without making the wrong choice

Buying a gaming monitor seems straightforward until you have to choose between terms such as 240Hz, HDR10, Adaptive Sync and 1ms. A high refresh rate sounds appealing, but it isn’t automatically the right choice for your computer, desk or games. A large screen can also be impractical if its resolution isn’t suited to its size.

The most common pitfalls are:

• Looking only at the highest Hz rating: a 240Hz monitor is most useful if your computer can also achieve very high frame rates in the games you play.
• Misunderstanding response times: 1ms MPRT and 1ms GtG are different measurement methods, so always check which figure is being quoted.
• Assuming HDR10 guarantees a noticeably better picture: HDR10 indicates compatibility with HDR content, but brightness, contrast and local dimming also affect what you see.
• Forgetting about connections: check whether HDMI or DisplayPort supports the resolution and refresh rate you want. You’ll also need a suitable cable and graphics card.

The key specifications of a gaming monitor

1. Size and resolution need to work together

A 24-inch gaming monitor with Full HD is practical for a compact desk and puts relatively little strain on your graphics card. A 27-inch gaming monitor can look sharper with QHD, or 2560 × 1440 pixels, than with Full HD. QHD is also an option at 32 inches, but viewing distance and pixel density become more important.

A 34-inch ultrawide monitor usually has a 21:9 aspect ratio. This gives you extra horizontal screen space and can work well for simulation games, multitasking and wide timelines. Check the width of your desk first: an ultrawide screen takes up considerably more space than a standard 16:9 monitor.

Common combinations include:

• Full HD monitor: 1920 × 1080 pixels, suitable for 24 inches and for high frame rates with a less powerful graphics card.
• QHD monitor: 2560 × 1440 pixels, a practical middle ground for 27 or 32 inches.
• 3440 × 1440: suitable for a 34-inch ultrawide monitor, but requires more graphics processing power.

2. Refresh rate and response time

Refresh rate is measured in hertz. A 144Hz, 180Hz, 200Hz or 240Hz monitor can display more frames per second than a 60Hz screen. The difference matters most in fast-paced shooters, racing games and competitive titles.

Consider how your hardware matches the monitor:

• 100Hz to 120Hz works well for everyday use, video and casual gaming.
• 144Hz to 180Hz is a good option for smooth PC gaming without stepping straight into the highest price bracket.
• 200Hz or 240Hz is most relevant when your PC can actually deliver those frame rates.

A quoted response time of, for example, 0.5ms MPRT or 1ms MPRT is not the same as GtG. MPRT is often linked to motion clarity settings, while GtG measures the transition between shades of grey. So don’t compare figures without checking the measurement method.

3. Panel type, synchronisation and connections

An IPS monitor usually offers wide viewing angles and consistent colour reproduction in its product specifications. A VA monitor is often chosen for its quoted contrast ratio. The overall picture also depends on brightness, factory settings and your surroundings.

A FreeSync monitor can match its refresh rate to the frame rate of a compatible AMD graphics card. Check whether FreeSync, Adaptive Sync or G-SYNC Compatible is officially listed for the model and the connection you’re using. Some screens may support a feature technically without official certification; this is not the same as certified compatibility.

Also check:

• HDMI and DisplayPort versions;
• number of video inputs;
• USB hub, USB-C or network port;
• VESA mounting;
• height adjustment, tilt, swivel and pivot;
• built-in speakers, if you need them.

Frequently asked questions about gaming monitors

Is 144Hz enough for gaming?

For many PC gamers, a 144Hz monitor is a practical choice. The screen can display up to 144 frames per second, but the benefit you actually get depends on your computer’s frame rate and whether the connection you’re using supports it. For highly competitive games, 180Hz, 200Hz or 240Hz may be worth considering.

How long does a gaming monitor last?

Its lifespan depends on how it’s used, heat, transport and the quality of the power supply. Place the screen securely, keep the ventilation openings clear and use a soft, dry cloth to clean the surface. Check the warranty and your statutory rights relating to conformity when you buy. The product specifications often include power consumption too, so you can estimate how much electricity it will use day to day.

Is a gaming monitor suitable for working from home?

Yes, depending on its size and connections. A 24-inch Full HD monitor fits on a small desk. A 27-inch QHD monitor gives you more room for documents and windows. USB-C with Power Delivery can be useful for laptops, while a 34-inch ultrawide monitor can make it easier to have several windows open side by side. As well as gaming features, look for height adjustment, tilt, a matt finish and the connections you need.
