If you are in country that uses a 50 Hertz (Hz) power frequency (a country other than the USA,
Canada or Mexico) and there is a noticeable flicker on the screen, click the Enable radio button
in this field. If you enable the flicker reduction feature, the flicker is reduced or eliminated, but

To eliminate the flicker at its source, you can use an electronic ballast instead of a magnet ballast
for the fluorescent lights at your installation. After you change the ballast for the fluorescent
lights, you can click the Disable radio button in the 50 Hz Flicker Reduction field.
