I never saw this before. Brand new M900 out of the box connected to a Dell monitor, Windows 10. Boots up and does not make a connection to the monitor. Monitor says no input source. Changed monitors, cables, different connections (HDMI, etc). Multiple reboots of each of the different setups. Monitor(s) remain black. Connected to the internet, reboot with Dell monitor and monitor displays comes to life. I thought it just needed to find it's drivers. Registered the machine and powered down. Later, booted up the M900 – monitor black again. Retried changing everything out again - no monitor. So I purchased a new Lenovo monitor. No luck, still a black monitor. I would appreciate any ideas.

Can you give further details about how the monitor came to life this time? What type of monitor cables have you tried? If you are using a DP adapter, please give the brand and model.
You don't give the form factor, is it a larger system, with the ability to plug in cards? Is there a card in the slot closest to the power cord?

Lenovo sent a tech out. After replacing the motherboard, testing memory, adjusting the Bios, and updating the drives, it came down to a bad video card. The decision was to return the machine and start over. I will say their customer service was outstanding. I'll continue to purchase Lenovo products in the future. Thanks again.
