Monitor Resolution

Monitor resolution depicts how clearly a monitor can show visual content.
  • Monitor resolution shows how many pixels a monitor has in width x height format.
  • For example, a 1920x1080 resolution means the width has 1,920 pixels and the height has 1,080 pixels.
  • The higher the monitor resolution, the more pixels, the clearer the picture will be displayed.

Refresh Rate

The number of times per second that your monitor screen refreshes the image being displayed on your screen.

Refresh rate is measured in hertz (Hz) and ranges from 60Hz up to 240Hz. The higher the refresh rate, the smoother your image will be.

If a monitor has a 60Hz refresh rate, this means that the picture on a screen would refresh 60 times per second.

Here are a few examples of how different refresh rates can be used:

  • 60 Hz - Creating spreadsheets, streaming movies or music
  • 144 Hz - PC gaming, photo sharing, video editing
  • 240 Hz - Competitive, eSports, and FPS gaming
Response Time

This refers to how much time it takes for monitor pixels to change from one color to another.

Response time is measured in milliseconds and is as fast as 0.5ms.

Unlike refresh rate, you want a lower response time – the lower the millisecond, the faster the screen can change an image.

Faster response times are key for gamers:

  • Reduce image ghosting
  • Minimize distortion and blurring
  • Sharp pictures for fast-moving gameplay

  • Your monitor port can be found on the back and/or sides of your monitor.
