Diagonal blue lines on CinemonitorIII monitor with RED camera and AJA downconverter

What the thread found

  • Diagonal blue lines appearing on a CinemonitorIII can indicate that the wrong video format standard has been selected on the monitor.
  • The CinemonitorIII contains a STANDARD menu setting where users must manually select between PAL and NTSC formats rather than relying on auto-detection.
  • The STANDARD menu setting on the CinemonitorIII is located alongside options for screen color choices, which can make it easy to overlook or confuse with other settings.

Depends on

  • The solution was specific to one operator's particular setup and mistake.
  • The original cause of the issue in this case was user error rather than a defect or incompatibility.
