How to resolve wrong or abnormal colors on my HIS Industrial Monitor?
- H
  hstephensonSep 2, 2025
  If you're seeing wrong or abnormal colors (where white isn't white), it could be due to: * Incorrectly adjusted monitor color settings. Try resetting the monitor to the factory default settings by activating the "Memory Recall" function in the OSD. * A video cable that is not securely connected. If any colors (red, green, or blue) are missing, check the video cable to ensure it is securely connected. * A bad video cable. Check for loose or broken pins in the cable connector, as shorts in the cable could cause an improper image to display.
