Common (generic) solutions for any kind of screen #

  • Eye patching . Fully blocking out one eye with an opaque eyepatch has helped a surprising number of forum members.
  • Go to a Binocular Vision Disorder (BVD) specialist to get checked for BVD. If you get a BVD diagnostic, ask for “prism lenses” (a special type of eyeglasses meant for BVD sufferers).
  • PWM (Pulse Width Modulation) means that the display is flickering in a particular way (in order to regulate brightness). Set your display’s hardware brightness to 100% and instead regulate brightness in a software way with apps like f.lux or Iris. Software dimming doesn’t produce PWM.
  • Temporal Dithering (TD) means a device (display, videocard…) cannot display some of the necessary shades, so it chooses the two nearest shades, and flickers between them very fast instead. On Windows (Intel GPUs), this can be disabled via ditherig.exe .
  • Minimal brightness is too high: There are many apps that can apply a black filter to the screen and thus reduce the screen brightness below the minimal system brightness. For Android , some such apps are Screen Dimmer, Screen Filter, Darker, Twilight. For Windows , one such app is Dimmer.
