Choosing a gaming monitor: check these specifications to avoid a bad buy

Buying a gaming monitor seems straightforward, until you realise that a high refresh rate, HDR and a low response time don’t always mean the same thing. A screen might, for example, advertise 240Hz, while your PC can barely deliver enough frames per second in your favourite games. And a larger screen isn’t automatically sharper or more practical.

For PC gamers, students, home workers and content creators, there are three main pitfalls to watch out for: marketing terms without context, a poor match between resolution and screen size, and ports that aren’t compatible with your computer. Read on to find out how to compare gaming monitors in practical terms.

Three common pitfalls when choosing a gaming monitor

1. Looking only at the highest refresh rate

A 144Hz gaming monitor, 240Hz gaming monitor or even a 320Hz model can display smooth motion, but the effect also depends on your graphics card, game settings and connection. A 240Hz monitor is most useful when your PC can also achieve a high frame rate in competitive games.

So check:

  • Whether HDMI or DisplayPort supports your desired resolution and refresh rate.
  • Whether your graphics card can deliver enough frames.
  • Whether Adaptive Sync is available for your graphics card.
  • Whether the stated response time uses GTG, MPRT or another measurement method.

A response time of 1ms MPRT isn’t directly comparable with 1ms GTG. So don’t just look at the smallest number in the product title.

2. Pairing a large screen with too low a resolution

A 32-inch monitor with Full HD can be attractively priced for gaming, but pixels are more noticeable across a larger screen than on a 24-inch display. For a 27-inch monitor, QHD is often a practical middle ground: more detail than Full HD without the graphics demands of ultra-high resolutions.

As a rule of thumb:

  • 24-inch Full HD: suitable for a compact gaming or work setup.
  • 27-inch QHD: a versatile choice for gaming, studying and office work.
  • 32-inch QHD: more screen space, but check that your desk is deep enough.
  • 34-inch ultrawide: handy for multitasking and expansive game worlds.
  • 49-inch super ultrawide: needs plenty of desk space and a powerful PC.

3. Assuming HDR10 guarantees a certain picture quality

HDR10 means that a screen can process this HDR signal. However, the final picture also depends on brightness, contrast, panel technology and the HDR support offered by the game or video. So, according to the manufacturer’s product specifications, HDR10 doesn’t automatically mean that every source will show visibly greater contrast or detail.

Also consider the panel type:

  • IPS monitor: wide viewing angles and generally consistent colours.
  • VA monitor: often has a higher stated contrast ratio, making it suitable for dark scenes.
  • OLED gaming monitor: self-lit pixels and a very high stated contrast ratio, but always check the guidance on static images in the user manual.
  • Curved gaming monitor: can feel more immersive on ultrawide or large screens, but takes up more space.

Which specifications really matter?

Resolution and screen size

A Full HD monitor with 1920 × 1080 pixels puts less demand on your PC and works well with a 24-inch screen. A QHD monitor with 2560 × 1440 pixels gives you more workspace and sharper detail at 27 or 32 inches. Ultrawide screens, for example, come in resolutions such as 3440 × 1440 or 5120 × 1440. Check in advance that your graphics card can handle the resolution at your desired refresh rate.

Refresh rate and Adaptive Sync

Refresh rate is measured in hertz. 100Hz, 144Hz, 180Hz and 240Hz can display smoother motion than 60Hz, provided the source delivers enough frames. Adaptive Sync, such as FreeSync, matches the screen’s refresh rate to the graphics card’s frame output. This can help reduce tearing and stuttering, but check compatibility and the supported range.

Connections, ergonomics and mounting

Don’t just look at the number of ports; check their version and bandwidth too. HDMI 2.0, HDMI 2.1 and DisplayPort versions can support different combinations of resolution and refresh rate.

These features are also useful for extended use:

  • Height adjustment, tilt and swivel.
  • VESA support for a monitor arm.
  • A built-in headphone jack or speakers.
  • USB-C with power delivery if you use a laptop.
  • A stable stand that suits the depth of your desk.

Frequently asked questions about gaming monitors

Is 144Hz enough for PC gaming?

For many players, 144Hz is a practical choice. The difference compared with 60Hz can be noticeable during fast movement, as long as your PC delivers enough frames. 240Hz or higher may be worth considering for competitive games, but the benefit depends on your frame rate, game and budget.

Is Full HD or QHD better for a 27-inch monitor?

At 27 inches, QHD generally offers more pixels per inch than Full HD. This can be useful for text, detailed games and multitasking. Full HD puts less demand on your graphics card and may be a better fit if your main aim is to achieve high frame rates.

How much power does a gaming monitor use?

Power consumption varies depending on the panel, brightness, size and refresh rate. Check the stated typical power consumption and energy rating. A large ultrawide or OLED screen may use a different amount of power from a compact Full HD monitor. Turn on energy-saving features and switch the screen off when you’re not using it.
