The screen contrast is too high or low

Explanation: The viewed image appears to have too little or too much contrast. Images with too little contrast appear dull and gray. Those with too much contrast (which is less common) can be too bright in some areas and too dark in others.

Diagnosis: The monitor probably needs to be adjusted.


  • Check the contrast control on the monitor and adjust it. You may need to adjust the brightness control as well, since they are related.
  • The monitor may need adjustment. In some cases a repair shop can adjust the controls to improve the contrast level, especially on older monitors where the internal settings may have drifted.
  • If possible, try changing the lighting in the room. A darker room can compensate somewhat for insufficient contrast.
