Choosing a gaming monitor: how to find the right speed, resolution and picture quality

Buying a gaming monitor seems straightforward until you start comparing specifications. A 240Hz screen sounds appealing, but it isn’t automatically right for your PC. Terms such as HDR10, 1ms and Adaptive Sync only tell you so much unless the rest of your setup is a good match.

The most common buying mistakes come down to three pitfalls:

  • A high refresh rate without enough frames: a 240Hz gaming monitor is most useful when your PC can deliver high frame rates at the resolution you’ve chosen.
  • A response time without a clear measurement method: 1ms MPRT, 0.5ms MPRT and 1ms GTG aren’t directly comparable. Always check which measurement the manufacturer uses.
  • A resolution that doesn’t suit the screen size: Full HD on a 27- or 32-inch screen can look less sharp than QHD on a 27-inch screen. Consider both the screen size and pixel density.

Which specifications should you check?

1. Resolution and screen size

A Full HD gaming monitor with 1920 × 1080 pixels puts relatively little strain on your graphics card. That makes Full HD a practical choice for esports, older systems and players who want a high refresh rate without placing too much demand on their system.

A QHD gaming monitor with 2560 × 1440 pixels displays more detail. At 27 inches, QHD is a popular choice for PC gaming and productivity. At 32 inches, QHD gives you a large viewing area, but the pixel density is lower than at 27 inches.

An ultrawide monitor, such as a 21:9 or 32:9 model, is a great option for simulation games, multitasking and video editing. Check in advance that your graphics card and games support the wider resolution.

2. Refresh rate and response time

The refresh rate determines how many times per second the screen can display a new image:

  • 144Hz gaming monitor: a sensible step up from 60Hz for smoother motion.
  • 165Hz gaming monitor: a little more headroom for fast-paced gameplay, especially with consistently high frame rates.
  • 180Hz gaming monitor: suitable for modern PCs that can run QHD games at high frame rates.
  • 240Hz gaming monitor: most relevant for competitive shooters and esports.
  • 320Hz: aimed at players looking for the fastest possible motion at Full HD.

A higher refresh rate only makes a difference if your computer can generate enough frames per second. You’ll also need a cable and connection that support your chosen resolution and refresh rate. The stated response time can depend on the overdrive or motion mode selected, so don’t compare products based only on the lowest figure in the product title.

3. Panel type, synchronisation and HDR

An IPS gaming monitor generally offers wide viewing angles. This is useful if you don’t sit directly in front of the screen, or if you also use the monitor for photo editing and office work.

A VA gaming monitor often offers higher contrast and deeper blacks, according to the product specifications. This makes it a good fit for films, dark games and curved screens. The experience with moving images can vary between models and settings.

An OLED gaming monitor uses self-illuminating pixels. According to the specifications of the models in question, this delivers deep blacks and a very low stated response time. If you’re considering OLED, it’s worth checking the maintenance features, user guide and warranty terms.

Adaptive Sync matches the refresh rate to your graphics card’s frame rate. A monitor with FreeSync is primarily aimed at AMD systems, while one with G-SYNC or G-SYNC Compatible is designed for NVIDIA setups. Always check the compatibility list for your graphics card and the connection you want to use.

HDR10 can expand the range of colours and brightness on screen, but the final HDR experience also depends on brightness, contrast, local dimming and the game or video itself. So an HDR10 label alone won’t tell you how noticeable the effect will be in practice.

Practical checks before you order

  1. Check that your PC or console supports your chosen resolution and refresh rate.
  2. See which cables are included. A DisplayPort cable isn’t supplied as standard with every model.
  3. Measure your desk, especially if you’re considering a 32-inch, ultrawide or curved monitor.
  4. Check how adjustable the stand is. Some models only tilt, while others also offer height and swivel adjustment.
  5. Compare the connections: HDMI, DisplayPort, USB-C, audio output and any USB hub.
  6. Check the energy rating and stated power consumption if the monitor will be on for long periods each day.

Frequently asked questions about gaming monitors

Is 144Hz enough for gaming?

For many PC gamers, 144Hz is a practical choice. Motion looks noticeably smoother than at 60Hz, while the demands on your graphics card are usually lower than with 240Hz. A higher refresh rate may be appealing for esports, provided your system can produce enough frames per second.

How long does a gaming monitor last?

Lifespan depends on usage, heat, settings and panel type. Keep the ventilation openings clear, use the correct power supply and follow the maintenance instructions. If you’re considering an OLED gaming monitor, it’s worth checking its built-in panel maintenance features and warranty terms in advance.

Does a gaming monitor use a lot of electricity?

Power consumption varies by size, brightness, resolution and panel type. Large ultrawide and OLED models can use more power than a compact Full HD monitor. So, if you’ll use the monitor every day, compare its stated typical power consumption and energy rating.
