Choosing a gaming monitor: size, resolution and connections

A good gaming monitor suits both your desk and your computer or console. The highest refresh rate in an advert does not by itself tell you whether your devices can use it.

The connection between monitor, computer and interface — The monitor, connection and your device must work together.

Start with desk space and viewing distance

Measure the space for the monitor, including stand depth and any monitor arm. If you sit close, a larger screen is not automatically more comfortable: your eyes also travel further from edge to edge. Check height adjustment and tilt if your desk position is awkward.

Resolution needs enough performance

Higher resolution shows more detail, but your graphics card also has to render it in games. Decide whether sharper images or higher frame rates matter more in the games you play. The monitor's advertised resolution is different from the game's actual frame rate on your computer.

Refresh rate and adaptive sync

Refresh rate describes how often a monitor can update its image per second. Adaptive refresh can match updates to frames from the graphics card. Check compatibility among the monitor, graphics card or console, connection and cable. A feature name on a product page does not tell you how it works in your exact setup.

Connections, panel and returns

Check the manual for which HDMI or DisplayPort connection supports your chosen resolution and refresh rate together. Also confirm the number of inputs you need, headphone output and any USB hub. If you cannot see the monitor in use, read the returns policy: colour, reflections and motion are best judged by trying it yourself.

Buyer's checklist

Before visiting a retailer, note the available space, your device's connections, the games you play and your requirements for the stand. Compare two or three suitable models using those points. Check the current price and exact model number with the retailer.
