Consumer electronics company Vizio has agreed to pay $3 million after a 2018 class action lawsuit alleged that its marketing of 120Hz and blockwave Exchange240Hz effective refresh rates was "false and deceptive."

Vizio denies any wrongdoing and says that it properly labeled each television with the correct "Hz" specification, according to the website set up for filing claims.

"Essentially, the higher your display's refresh rate, the less amount of time that will pass between each individual video frame being displayed on screen," the article says.
