Choosing a gaming monitor: how to compare specifications without overspending

Buying a gaming monitor seems straightforward until you find yourself comparing dozens of screens with terms such as 144Hz, HDR, Adaptive Sync and 1 ms response time. Many models sound similar, but can differ significantly in resolution, connections, panel technology and ergonomics.

Most disappointing purchases come down to three common pitfalls:

  • Looking only at the refresh rate: 144Hz sounds appealing, but your PC or console also needs to deliver enough frames per second.
  • Assuming HDR guarantees a better picture: HDR support alone tells you little about brightness, contrast or the quality of local dimming.
  • Choosing the wrong resolution for the screen size: Full HD on a large screen can look less sharp than QHD from the same viewing distance.

The right monitor depends on the games you play, your hardware, desk, viewing distance and other tasks. Read on to find out which specifications to check and which models suit different types of user.

Which specifications matter?

1. Resolution and screen size

Resolution determines how many pixels the screen displays:

  • Full HD, 1920 × 1080: often a practical choice for 24-inch screens and systems that need to reach high frame rates.
  • QHD, 2560 × 1440: a useful middle ground for 27-inch screens. A QHD gaming monitor displays more detail than Full HD without putting the same strain on your graphics card as 4K.
  • 4K, 3840 × 2160: ideal for sharp images, productivity and consoles that support 4K output. Your graphics card will need enough power to handle it.

Also consider your viewing distance. A 32-inch 4K monitor can be comfortable for work and entertainment, while a 24-inch Full HD model is often easier to take in at a glance during competitive games.

2. Refresh rate and response time

Refresh rate is measured in hertz. A 144Hz gaming monitor can display up to 144 frames per second. This can make movement look smoother than at 60Hz, but only if your computer or console can produce enough frames.

A monitor with a high refresh rate isn’t automatically faster in every situation. Check the stated response time and how it was measured, too. Manufacturers may use GTG, MPRT or their own testing conditions. So don’t compare a 0.03 ms figure directly with 1 ms without checking the method used.

For laid-back single-player games, 120Hz or 144Hz may be enough. For fast-paced PC games, 180Hz, 240Hz or 480Hz could be worth considering, but you’ll need suitable hardware to make the most of them.

3. Panel, synchronisation and connections

An IPS monitor typically offers wide viewing angles and is a popular choice for gaming, everyday work and colour-critical tasks. VA panels can offer higher static contrast. According to the stated product specifications, OLED and QD-OLED screens deliver very deep blacks and fast pixel response, but check the warranty and guidance on displaying static images for long periods.

FreeSync, Adaptive Sync and G-Sync Compatible are synchronisation technologies that match the screen’s refresh rate to the graphics card’s output. Check that your PC, graphics card and connection support the feature you want to use. An HDR monitor can display more dynamic images, but the result also depends on brightness, contrast and the game or video itself.

Finally, look out for:

  • DisplayPort and HDMI version: important for QHD or 4K at high refresh rates.
  • USB-C with Power Delivery: handy for connecting a laptop and keeping your desk tidy.
  • VESA mounting: useful if you want to use a monitor arm.
  • Height-adjustable stand: check whether it only tilts or can also swivel and adjust in height.
  • KVM, Picture by Picture or Picture in Picture: useful if you use multiple computers.

Frequently asked questions about gaming monitors

Is 144Hz a good choice for a gaming monitor?

For many PC gamers, 144Hz is a practical choice. You’ll benefit most when your system can deliver around 144 frames per second in the game you’re playing. Also check that your DisplayPort or HDMI connection supports your chosen resolution and refresh rate.

Is an OLED gaming monitor suitable for long-term use?

According to the stated product specifications, OLED models offer deep blacks and fast pixel response. If you display static elements, such as a desktop or game interface, for long periods, manufacturers often recommend using the screen care features and following the maintenance guidance provided. Also check the warranty terms for information about possible image retention.

Does a 4K monitor use more power?

Power consumption varies by panel, screen size, brightness and HDR setting. Check the energy label and the stated consumption per 1,000 hours. HDR at high brightness can increase power use. For a fair comparison, use the same picture mode and check the model’s official energy label.
