What to do if my BenQ ST4301K has no picture?

If your BenQ Monitor displays no picture, please check the following: Ensure the display and the signal source device are turned on. Verify all cable connections are secure. Confirm that the computer, DVD, or Blu-ray disc player's output resolution is supported (refer to Supported input signal resolution on page 62).
