The screen image is blurry, particularly lines and other features that should be displayed as sharp

Explanation: Images on the screen appear blurry or poorly defined.

Diagnosis: This is usually a problem with the monitor itself. It can be the cable as well. It is sometimes adjustable with a control on the outside of the monitor.


  • If there is a control called "focus" or "sharpness", try to adjust the focus level. The control for this may be at the back of the monitor.
  • Check the cable to ensure it is straight and making good contact. Try replacing the cable if possible.
  • Take the monitor in for repair. There is a chance that a repair shop can restore sharp focus on the screen.
