Although Vizio TVs tend to be configured to work fully out of the box, users often find it necessary to change specific Vizio TV settings to their liking, such as the brightness of the TV. Changing the brightness of the Vizio TV makes a big difference in the image quality and can make watching TV easier on the eyes. By going to the correct section of your Vizio TV's settings, you can make the TV brighter.
Press "Menu" on your Vizio TV's remote control.
Press the "down arrow" key to select "Brightness."
Press the "right arrow" key to increase brightness. Keep pressing the key to increase brightness more.
Press the "left arrow" if you increase the brightness too much and would like to decrease it.
Press "Menu" to exit after changing the brightness to your liking.
