What is Moire? Why does my monitor have this wavy phenomenon?

Published on 2017-01-09

Moire is a natural effect or phenomenon of CRT that has the appearance of a wavy pattern, which is repetitive and superimposed on the screen as ripple images. These are a few suggestions to help reduce or minimize the effects:

  • Some monitors have a Moire cancellation feature, activate it to the on position or adjust the Moire cancellation function via the OSD on the monitor.
  • Change resolution to the recommended standard for the specific monitor size.
  • Change Window viewing pattern/scheme to a pattern where the Moire is less visible.
  • Change horizontal and vertical size to optimize the reduction of the Moire effect.
