Troubleshooting system startup failure
If you boot the system to the BIOS boot mode after installing an operating system from the UEFI Boot Manager, the system stops 
responding. To avoid this issue, you must boot to the same boot mode in which you installed the operating system.
For all other startup issues, note the system messages that appear on the screen.
Troubleshooting external connections
Before troubleshooting any external devices, ensure that all external cables are securely attached to the external connectors on your  system before troubleshooting any external devices.
Troubleshooting the video subsystem
Prerequisites
NOTE: Ensure the Local Server Video Enabled option is selected in the iDRAC Graphical User Interface (GUI), under

Steps
1.Check the cable connections (power and display) to the monitor.
2.Check the video interface cabling from the system to the monitor.
3.Run the appropriate diagnostic test.
If the tests run successfully, the problem is not related to video hardware.
