How to Choose the Right Monitor for Gaming

As a gamer, you want to get the most out of the sports, racing, and any action game. The first step to achieve this is by having a gaming PC and a gaming monitor that displays all the action you need without subjecting you to blurred images or flickering. Gaming factors are available in the market at varied sizes, flairs, and even different priced tags. Selecting the right monitor is a pretty subjective matter as it draws down to balancing many aspects to get the right monitor that delivers a smooth gaming experience. The following are tips you can follow on how to choose the right monitor for gaming.

Resolution and Screen Size

computer monitorThe two go hand in hand. The bigger the screen size, the better the gaming experience. The screen size you choose entirely depends on you, so if you are going for a 1080p monitor, then consider a screen size of 24 inches. The best sizes for gaming monitors is between 21 inches and 27 inches. For instance, a 27-inch screen will serve you right and will even allow you to go beyond the full high-definition, which offers a resolution of 1920 by 1080. A higher resolution means a higher pixel count which translates to higher image clarity and better visual detail.

Refresh Rate and Pixel Response

The monitor you choose should have a high refresh rate as well as a fast pixel response. The refresh rate is typically the time the monitor takes to redraw the entire screen measured in Hertz. A higher refresh rate, for instance, a refresh rate of 120Hz or more will help to reduce the image blur and eliminate tearing, therefore, improving the gaming experience.

Connectors and Video Inputs

The gaming monitor you choose should come with a variety of connectors and video inputs that help to keep you connected to multiple PCs. Some of the inputs and outputs (connectors) the gaming monitor should have included a 5mm audio out for connecting the speakers or headphones directly to the monitor, an HDMI 1.4/2.0 for transferring both video and audio and a display port 1.4 also for transferring video and audio on the PC.
