Buying a gaming monitor: how to choose the right monitor for PC gaming

Buying a gaming monitor seems straightforward until you start comparing the specifications. A high refresh rate, low response time and HDR all sound appealing, but they only matter if they suit your games, graphics card and desk. A screen that looks impressive on paper might be too large, too dim or difficult to connect in practice.

Here are some common pitfalls to watch out for:

  • Looking only at the highest Hz figure: a 240Hz gaming monitor offers little benefit if your PC can’t achieve a high frame rate in your favourite game.
  • Comparing response times without checking the measurement method: 1 ms MPRT and 1 ms GtG are not the same. Always check which figure the manufacturer quotes.
  • Treating HDR as a guarantee of quality: HDR10 or DisplayHDR doesn’t automatically mean a screen has high brightness or strong contrast.
  • Underestimating the size of an ultrawide: a 34-inch gaming monitor or 49-inch SuperWide screen needs plenty of desk space and a suitable viewing distance.

Which specifications matter?

1. Resolution and screen size

Resolution determines how many pixels the screen displays. Full HD (1920 x 1080) is a practical choice for an affordable gaming monitor, especially at 24 or 27 inches. At 27 inches, however, Full HD may look less sharp than WQHD (2560 x 1440).

A WQHD monitor gives you more space and detail without the high graphics demands of 4K. For a 27-inch screen, WQHD is a sensible choice for PC gaming, streaming and everyday use. A 4K monitor with 3840 x 2160 pixels shows more detail, but also puts greater demands on your graphics card.

An ultrawide gaming monitor with 3440 x 1440 pixels, such as a 34-inch model, gives you extra horizontal space for racing games, simulations, open-world games and multitasking. Before you buy, check that your desk can accommodate the width of the screen, with room left for speakers and cables.

2. Refresh rate and synchronisation

Refresh rate is measured in hertz. A 60Hz monitor refreshes the image 60 times per second; a 175Hz gaming monitor or 240Hz gaming monitor can display motion more smoothly, provided your PC can deliver enough frames.

A high refresh rate monitor can be useful for competitive shooters. For story-driven games or work, 144Hz to 180Hz is often a practical choice. Also look out for variable synchronisation:

  • FreeSync is designed for compatible AMD systems and can reduce screen tearing.
  • G-Sync Compatible works with certain NVIDIA configurations, but check whether the specific model is officially certified.
  • Check the maximum refresh rate for each connection. HDMI and DisplayPort may have different limits on the same screen.

3. Panel type, HDR and connections

IPS panels are generally known for their wide viewing angles and consistent colours. VA panels often offer higher static contrast. An OLED monitor uses pixels that can switch off individually, allowing dark areas to appear very deep according to the product specifications. If you display static images for long periods, it’s a good idea to use the brand’s OLED protection features.

A QD-OLED gaming monitor combines OLED technology with quantum dots. For example, the MSI MAG 272QP QD-OLED X24 lists a WQHD resolution, 240Hz, 0,03 ms GtG, HDR True Black 400, FreeSync Premium and G-Sync Compatible. When checking HDR, look at both the certification and the stated brightness. Certification alone doesn’t describe the full viewing experience.

Connections are particularly important for laptops and home working. USB-C with Power Delivery can combine a video signal and charging, but check the maximum wattage. HDMI 2.1 is relevant for modern consoles and higher resolutions or refresh rates. An adjustable stand, VESA support and a USB hub can make more of a difference day to day than built-in lighting.

Frequently asked questions about gaming monitors

Is a 240Hz gaming monitor always a good choice?

Not necessarily. A 240Hz gaming monitor is most relevant for esports and fast-paced shooters if your PC can also deliver frame rates of around 240fps. For single-player games, work and general use, 144Hz to 180Hz can offer a practical balance between smooth visuals and system demands.

Is OLED suitable for extended PC use?

An OLED monitor can be suitable for gaming and creative work, but it’s worth taking care with static elements such as taskbars and programme windows. Use the built-in pixel protection, avoid leaving the screen on the same still image for too long, and follow the manufacturer’s care instructions.

Does a large gaming monitor use a lot of power?

Power consumption varies depending on the panel type, brightness, resolution and HDR mode. Check the energy label and the stated figures for SDR and HDR. A large ultrawide screen may use more energy than a compact Full HD model. Switch the screen off when you’re not using your PC for an extended period.
