Use these steps to check the display.
● Visually examine the display for cracked screen, liquid crystal leak, dirty spots on glass, and other
issues.
● Reset and update BIOS and docking firmware.
● Update operating system (OS), graphics or video drivers (Intel, AMD, NVIDIA, and others).

error, graphics or video issues) in the BIOS Legacy setting.
● Configure Windows settings (Power options, Screen brightness, Personalization, Screen resolution,
and so on).
● Test with a verified working external display.
● Boot to Windows in safe mode.
