Buying a gaming monitor: how to choose a screen that’s right for you

Buying a gaming monitor seems straightforward until you start comparing the specifications. 144Hz, 240Hz, HDR, OLED, Adaptive Sync and all sorts of response times are prominently displayed on the packaging. But one impressive number doesn’t tell you everything. A screen may be fast, but still not suit your PC, console, desk or favourite games.

The most common pitfalls:

• A high refresh rate without a sufficiently powerful graphics setup. A 240Hz monitor offers little benefit if your PC only manages 100 frames per second in your games. The HDMI or DisplayPort connection you use must also support your chosen resolution and refresh rate.
• Comparing response times measured in different ways. GtG, MPRT and overdrive aren’t directly comparable. Check the full product specification rather than focusing only on the lowest figure.
• Assuming HDR guarantees impressive contrast. “HDR Ready” and certified HDR formats are different designations. Brightness, panel type and local dimming all help determine how HDR content looks.
• Overlooking size and ergonomics. A 34-inch ultrawide gaming monitor takes up considerably more desk space than a 24-inch screen. Also check whether the stand is height-adjustable and whether VESA mounting is supported.

The key specifications explained

1. Resolution, size and viewing distance

A 24- or 27-inch Full HD gaming monitor is generally easy to fit on your desk and requires less graphics processing power. A QHD gaming monitor with 2560 × 1440 pixels offers more detail, especially at 27 inches. For 4K gaming, you’ll need a screen with 3840 × 2160 pixels, as well as a graphics card capable of running that resolution at your chosen refresh rate.

A 4K gaming monitor is a good option for single-player games, creative work and consoles that support 4K. For competitive shooters, QHD or Full HD may be more practical, as higher frame rates are easier to achieve.

An ultrawide gaming monitor usually has a 21:9 aspect ratio. This gives you extra horizontal screen space and works well for racing games, simulators and multitasking. Check in advance that your favourite games support this aspect ratio properly.

2. Refresh rate and synchronisation

A 144Hz gaming monitor is a natural step up from 60Hz. Movement and cursor motion look smoother when your computer can deliver enough frames. A 240Hz gaming monitor is aimed mainly at players of competitive games with a powerful PC.

Adaptive Sync matches the screen’s refresh rate to the graphics card’s frame output. This can help reduce tearing and stuttering. Check the official compatibility carefully:

• FreeSync or FreeSync Premium is primarily designed for compatible AMD hardware.
• G-SYNC Compatible refers to tested compatibility with certain NVIDIA systems.
• A monitor with Adaptive Sync alone may work with multiple systems, but performance depends on the combination of monitor, graphics card, cable and driver.

3. Panel type, HDR and connections

An IPS gaming monitor is known for its wide viewing angles and consistent colour reproduction. According to product specifications, VA panels often offer higher static contrast. An OLED gaming monitor uses self-lit pixels and can display very deep blacks. If you’re considering OLED, it’s worth reading the information about pixel protection, usage modes and the warranty against image retention.

For HDR, check specific figures such as brightness and certification. A label such as HDR Ready doesn’t automatically mean the same viewing experience as DisplayHDR True Black 400 or another certified standard.

Also check:

• HDMI version for PC and console;
• DisplayPort version for high resolution and refresh rates;
• USB-C, with or without power delivery;
• headphone output and built-in speakers;
• VESA size, for example 100 × 100 mm;
• height adjustment, tilt, swivel and pivot.

Frequently asked questions about buying a gaming monitor

Is 144Hz enough for PC gaming?

For many players, 144Hz strikes a practical balance between smooth motion and the graphics performance required. The difference compared with 60Hz is most noticeable in fast-paced games and when scrolling smoothly. 240Hz is only worthwhile if your computer can also achieve a high frame rate in the game you’re playing.

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

According to the product specifications, OLED offers deep blacks and a very low stated response time. If you use the screen for long periods with static elements, such as a taskbar or interface, it’s worth using the built-in OLED protection features and checking the warranty and image-retention information. Practical lifespan depends on brightness, usage time and content.

Does a gaming monitor use a lot of electricity?

Power consumption varies depending on the panel, size, brightness and HDR setting. Check the energy label and the stated figures for SDR and HDR. A large 4K or ultrawide screen may use more power than a compact Full HD model. Switch the screen off completely if you won’t be using it for a while, and check that sleep mode is working correctly.
