Buyers Guide for the Best 21 Inch Computer Monitors

Before you take the leap and buy your monitor, there are a number of factors that you should take into consideration. Here are the important factors to consider when buying a 21-inch monitor.

Type of Panel (TN, VA, or IPS)

There are three major LCD panels used in modern monitors:

  • TN – Twisted Nematic panels deliver the fastest response rates but have a reduced viewing angle of 160°.
  • VA – Vertical Alignment panels offer the best contrast and produce vivid color. However, these panels typically have the longest response times.
  • IPS – In-Plane Switching panels are modern and produce impressive color while offering up to 180° wide viewing angles.

Screen Refresh Rate

Measured in Hertz (Hz), a monitor’s screen refresh rate is the number of times it refreshes the display in a single second. Screens producing above 30 Hertz will appear natural to the human eye during action scenes in movies or games. Modern monitors match the graphics cards refresh rate to ensure a flicker-less image is displayed.

Response Time

A monitor’s response time is how long it takes for a pixel to change from one color to another. This is typically done by recording the time it takes for a black pixel to turn white and then black again. A monitor with a lower response time is less likely to have blurring or ‘ghosting’ issues. A low response time is crucial for fast-paced or shooter games.

Resolution & Pixel Density

Looking for a retina display monitor for your pc? Retina display is typically a screen with 144ppi and is mostly found in larger, 4k monitors.

All of the recommended monitors we have recommended are 1920 x 1080 screen resolution and have a pixel density of 102ppi.
