Glossary - Ghosting

Ghosting occurs when an image continues to stay on a screen even when the visuals have changed. They are the multiple impressions of an image on a screen. It occurs when the pixels get blurred because of several reasons; it can either happen due to the monitor speed or the inability of the monitor to function correctly due to the high resolution the player uses. 

Another reason can be when the response time of the monitor is slow. When the monitor keeps restarting, it can delay in speed to keep pace with the transmissions. So the two major causes of ghosting are the rate of refreshing and the response time. 

Let’s get into it! 

2 Major Causes Of Ghosting

The rate of refreshing refers to the frequency of how a screen refreshes. When a screen refreshes each time, a new image replaces the previous image. The measurement used is in Hertz (Hz), and 60Hz, which means 60 frames per second is the lowest standard refresh rate. Most devices use 60Hz, but others range from 75Hz to 144Hz. 

The response time refers to the time it takes for a Central Processing Unit (CPU) to display a new image over the previous image. It entails the pixels of the image, and the speed it takes for the colors on the screen to change. So, if the response time is high, it means it’ll take a long time for the next image to appear. The ideal response time is three milliseconds. 

Other factors that can cause ghost images include: 

  • Screen tearing

  • Flickering 

  • Stuttering 

  • Input lag

These factors don’t happen alongside ghosting; however, it occurs when the monitor doesn’t have enough speed to function correctly. Ghost images can ruin the gaming experience, and the overall adventure and excitement of the video game. Ghost imaging doesn’t happen only in video games. It can occur particularly on any screen. 

Ghosting can cause havoc when playing video games, but it’s simple to correct the problem by updating the drivers, checking the cables, or getting a new monitor.
