My monitor displays normally. But it can’t keep the input source I selected last time or always shows “No Cable Connected” or “No Signal Detected” after I power off and on my monitor/PC. What should I do?

Please check the following:

  1. Power on your monitor, switch to the input source which you want to keep.
  2. Go to 'Menu' in the OSD, select "Save" > "Save Settings" > "Yes".
  3. Power off and on your monitor to see if the input source keeps.
