Choosing a gaming monitor: how to compare size, speed and picture quality

Buying a gaming monitor might seem straightforward: pick a large screen, a high refresh rate and a low response time. In reality, marketing claims and incomplete specifications can lead to a purchase that doesn’t suit your PC, console or workspace. Use these checkpoints to compare models on the features that actually make a difference.

Common pitfalls when buying a gaming monitor

1. Only looking at the highest hertz number

A 240Hz monitor or 320Hz monitor sounds appealing, but your computer also needs to deliver enough frames per second. If your graphics card hovers around 100 fps in your favourite game, you won’t be using a large part of that high refresh rate. For many players, a 144Hz monitor, 165Hz monitor or 180Hz monitor offers a practical balance between smooth visuals and system load.

Also pay attention to the connection. Check whether the combination of resolution and refresh rate is supported via HDMI or DisplayPort. The Alienware AW2525HM, for example, lists HDMI 2.1 and DisplayPort 1.4, while other models use HDMI 2.0.

2. Misinterpreting a low response time

A stated response time of 0.5 or 1 millisecond can depend on the measurement method, such as MPRT or GtG, according to the product specification. These values are therefore not always directly comparable. Alongside the response time, look at the panel type, the refresh rate and any overdrive settings.

3. Not matching resolution and screen size

A 27 inch gaming monitor with Full HD offers a lower pixel density than a 24 inch gaming monitor with the same resolution. Text and fine details can therefore look less sharp up close. A QHD gaming monitor with 2560 × 1440 pixels typically gives you more workspace and detail on a 27 inch screen, but also demands more graphics performance.

The key specifications explained

Size, resolution and viewing distance

  • 24 to 25 inches: suitable for compact desks and competitive games where you want to see the entire screen at a glance.
  • 27 inches: a versatile size for gaming, working from home and streaming.
  • 31.5 to 32 inches: more screen for single-player games and productivity; a QHD resolution is often more logical here than Full HD.
  • 34 inches ultrawide: offers a 21:9 aspect ratio. An ultrawide monitor can be handy for two windows side by side or a wide field of view in supported games.
  • 49 inches: models with 32:9 are wide and require a sturdy, deep desk. Check the available space and VESA support beforehand.

A Full HD gaming monitor with 1920 × 1080 pixels is often sufficient for a mid-range computer or console. QHD is more interesting when you want more detail and your hardware can handle it. For creative applications and compatible consoles, 4K models also exist, but a higher resolution demands more from your graphics card.

Refresh rate and synchronisation

The refresh rate is expressed in hertz. A 180Hz screen can display up to 180 image refreshes per second. This helps especially in fast games when your computer also produces a similar frame rate.

FreeSync monitors adjust the refresh rate to the frame output of a compatible AMD graphics card, according to the product specification. With a G-SYNC monitor, this happens with compatible NVIDIA hardware. Always check whether the desired combination is officially supported. The LG 34WR50QK lists FreeSync; the product information also states that G-SYNC may work, but is not officially marked as compatible.

Panel type and image quality

  • IPS monitor: often chosen for wide viewing angles and consistent colours. This suits gaming, office work and photo editing.
  • VA monitor: in the product specifications, this often means higher static contrast. That can be pleasant for dark scenes, although response time and motion handling can vary between models.
  • OLED: can deliver deep black levels and high contrast. For long periods of static images, check the manufacturer’s information on usage and maintenance.

Features such as HDR10 are no guarantee of the same picture quality on every screen. Check brightness, contrast, panel type and any certification together. According to the product information, the LG 27U411A-B supports HDR10 and has a brightness of 250 cd/m². That is relevant, verifiable information alongside the feature name.

Frequently asked questions about a gaming monitor

Is 144Hz enough for gaming?

For many PC games, a 144Hz monitor is a practical choice. You benefit from smoother motion than at 60Hz, as long as your computer produces enough fps. For competitive games, 180Hz, 240Hz or 320Hz can be interesting, but the difference depends on your hardware, game and personal preference.

Is a curved gaming monitor suitable for console use?

It can be, but check the resolution, HDMI version and console support. A curved screen like the MSI MAG 275CQDF X24 uses 16:9 and has HDMI connections. An ultrawide monitor can be less practical with consoles when games don’t support a 21:9 aspect ratio.

How much power does a gaming monitor consume?

Consumption varies per model, brightness, HDR setting and usage time. Check the energy label and the stated power rating. A higher refresh rate or brightness can affect consumption. Turn the screen off when not in use and use automatic sleep mode for longer work or gaming sessions.
