How to choose a gaming monitor: Find the perfect screen for your setup

Buying a gaming monitor seems simple until you start comparing refresh rates, response times, HDR standards and sync technologies. A high number on the box doesn't automatically mean the screen is the right fit for your PC, games or workspace.

The most common purchasing mistakes are caused by three pitfalls:

  • A high refresh rate without the right hardware: a 240Hz monitor offers little practical benefit if your PC can't achieve a high frame rate in your favourite games.
  • A response time without a clear measurement method: 0.5 ms MPRT and 0.5 ms GtG are not the same. Always check which standard the manufacturer is using.
  • HDR as a marketing label: HDR10 or HDR Ready on its own doesn't tell you how much brightness, contrast and local dimming a screen actually offers.

Size is also often underestimated. A 34-inch gaming monitor takes up a lot of desk space and requires a good viewing distance. Therefore, you should measure not only the width of the screen but also the depth of the stand and the space needed for cables.

The most important specifications for a gaming monitor

1. Resolution and screen size

A QHD monitor with a resolution of 2560 × 1440 pixels offers significantly more detail than Full HD, without the same graphical demands as 4K. For a 27-inch monitor, 1440p is often a practical balance of sharpness and performance. A 1440p monitor pairs well with modern mid-range and high-end graphics cards.

An ultrawide monitor typically uses a 21:9 aspect ratio. For a 34-inch screen, 3440 × 1440 is a common resolution. This gives you extra horizontal space for games, video editing and side-by-side windows. Check beforehand whether your games support ultrawide resolutions; some titles may display black bars or stretched aspect ratios.

For work and multitasking, a 32:9 screen can offer even more space. On the other hand, a monitor like this is wider and often needs to drive a higher resolution.

2. Refresh rate and synchronisation

The refresh rate is expressed in hertz (Hz). A 100Hz monitor can display up to 100 frames per second, while a 180Hz monitor or 240Hz monitor is suitable for very smooth motion when your computer can deliver enough frames.

Pay attention to these points:

  • Check if the desired refresh rate is available via DisplayPort or HDMI.
  • Look at the maximum resolution in combination with the refresh rate.
  • Check if your graphics card supports FreeSync, G-SYNC or a compatible variant.
  • Consider the included cable and the version of the port.

A monitor with FreeSync can help reduce screen tearing and stuttering when the frame rate fluctuates. For G-SYNC Compatible, you should check if the specific model is officially certified. A product listing might state that a screen may work with G-SYNC without official compatibility status. In that case, its performance isn't guaranteed.

3. Panel, response time and HDR

According to product specifications, a VA panel typically offers high static contrast and deep dark tones. IPS panels are known for their wide viewing angles and consistent colours. OLED and QD-OLED screens work with self-illuminating pixels. According to the product information, they can provide extremely deep blacks and fast pixel response times.

With an OLED gaming monitor, it's wise to read the warranty terms regarding image retention and burn-in. A static desktop, interface element or scoreboard that remains visible for a long time is something to be aware of. Also, look for built-in pixel protection features and the recommended usage settings.

HDR depends on more than just the label. Look at the specified brightness, contrast, colour space and HDR standard. Claims about colour coverage or image enhancement come from the brand's product information, so check whether the figures are based on factory measurements and which settings were used to obtain them.

Choose based on how you'll use it

A monitor for PC gaming doesn't need the same features as a screen for competitive esports. You should also consider your desk, viewing distance, available ports and the ergonomics of the stand.

Practical checks before you order

  • Desk and viewing distance: measure the available space for a 34-inch gaming monitor or a larger model.
  • Connections: check the DisplayPort and HDMI versions, especially for QHD, ultrawide and high refresh rates.
  • Ergonomics: a height-adjustable, tilting or swivelling stand helps you to position the screen correctly.
  • VESA compatibility: check the size, such as 75 × 75 or 100 × 100 mm, if you plan to use a monitor arm.
  • Warranty: read the statutory warranty and any additional manufacturer's warranty. For OLED models, you should specifically look at the terms regarding image retention.

Frequently asked questions about gaming monitors

Is 1440p suitable for PC gaming?

Yes, 1440p offers more detail than Full HD and typically requires less graphical power than 4K. The right choice depends on your graphics card, games and desired refresh rate.

How long does a gaming monitor last?

The lifespan depends on usage, heat, brightness and the panel type. Ensure proper ventilation, use appropriate settings and follow the manufacturer's maintenance instructions. With OLED, it's wise to factor pixel protection features and warranty conditions into your decision.

Does a high-refresh-rate monitor use more power?

It can, depending on the panel, brightness, resolution and settings. Check the specified typical power consumption and the energy label. A high refresh rate doesn't always use maximum power, but the screen and the connected PC can draw more energy during intensive use.
