The first thing to look for is resolution, which basically refers to the visual ability of a game - how many pixels a display can show you. If a resolution consists of more pixels, you'll enjoy a clearer picture.
The refresh rate measures how many times per second a display draws a new image. For example, if the refresh rate is 60 Hz, the display refreshes the image 60 times per second.
Screen size is also important because it can impact your gaming experience. Do you want the largest screen possible? Do you prefer a curved screen? These are prime considerations.
The ports that a monitor has, whether HDMI, headphone jack, USB, or all three, have an impact on what you can use with your monitor.
Gaming monitors come in one of three panel types: TN, or Twisted Nematic panels, which support refresh rates of up to 240 Hz; IPS, or In-Plane Switching panels, with refresh rates of 200 to 240 Hz; and VA, or Vertical Alignment panels, which also go up to 240 Hz.
TN panels offer the fastest response time at 3 to 4 ms, IPS panels are a bit slower at 4 to 6 ms, and VA panels average 8-12 ms.
