How to Get the Brightness Back on a TI-84 Plus

Save

The TI-84 Plus graphing calculator displays its output on a small black and white screen. Under certain lighting conditions, you may find that the screen is too bright and needs to be dimmed for improved visibility. If you ever want to increase the brightness for a more vibrant image, you can do so using several buttons on the front of the calculator.

  • Press "ON" to turn on the TI-84 Plus calculator.

  • Press the button labeled "2ND."

  • Press the up-arrow button on the front of the calculator. This will increase the brightness on the screen. To further increase the brightness, press "2ND" and then press the up-arrow button again. Repeat to continue increasing the brightness incrementally until the desired level is achieved.
