What is ghosting on a monitor?

Ghosting on a monitor refers to a phenomenon where moving objects on the screen leave a trail or shadow behind them. This can happen when the pixels on the display are unable to switch fast enough to keep up with the motion of the object, resulting in a blur or ghostly image.

Ghosting can be caused by a variety of factors, including slow response times of the monitor, high input lag, low refresh rates, or poor quality cables. It is most commonly seen in fast-paced video games or movies, where quick movements are more likely to cause ghosting effects.

To reduce or eliminate ghosting on a monitor, it is important to choose a display with a fast response time (usually measured in milliseconds), a high refresh rate (such as 120Hz or higher), and connect using high-quality cables. Adjusting the settings on the monitor and graphics card may also help improve the overall picture quality and reduce ghosting effects.
