A black screen on a secondary monitor is typically caused by one of two issues: the graphics card or the display. If the graphics card is the problem, then you’ll need to troubleshoot and fix it.

Second Monitor is Black: Troubleshooting Methods
The graphic card and display is the only problem to consider which cause the secondary monitor to go black below we’ll discuss the best way to troubleshoot steps of these problems:
1. Graphic Card
Fix 1. Disconnect and Connect the Cables
If the black screen is caused by a graphics card, first try to disconnect and reconnect actual hardware cables. Sometimes when there’s an issue with the graphics card, it can cause a black screen on the monitor as well. If that doesn’t work, you’ll need to take your computer to a repair shop or tech for further diagnosis and repair.
Fix 2. Check the Power
Make sure the power button is turned on to the monitor. Sometimes when there’s an issue with the graphics card, it can cause the screen to go black.
Fix 3. Check the Monitor Cable
If you’re experiencing a black screen on the 2nd monitor, make sure the video port cable is not loose. Check that all cables are secure and connect power options properly to both monitors. If there’s an issue with your graphics card or secondary or primary display, it can cause a black screen on the second dual monitor
Fix 4. Update the Computer’s Display Drivers
Update the drivers from the manufacturer if you have a third-party discrete graphics card. Visit the motherboard or computer manufacturer’s website to see if there are any updated drivers for those capabilities if you plug the monitor into the motherboard’s display adapter connectors.
2. Display
Fix 1. Check Display Source and Resolution
Increasing the screen’s resolution may cause it to go black in certain circumstances. If the black screen is caused by a resolution issue, you may be able to fix it by changing the monitor source. You can also try using a different power cable or video adapter.
Fix 2. Check Display Settings
If the black screen is only appearing on one monitor display and not both, check your secondary display settings to make sure they’re correct input. Make sure there’s nothing blocking graphics from displaying properly on the screen and that your monitors are connected to the graphics driver card.
Fix 3. Check Display Cable Connection and Adapter or Monitor Input
If the black screen on the second original monitor is only appearing when you plug a cable into the second monitor ports video cable input, try connecting your monitors with different cables instead of using adapters; this can help resolve some issues with displays that are not connected properly to the graphics card and allow them to work correctly.
Fix 4. Adjust the Monitor’s Refresh Rate
If you’re experiencing black screens on both monitors, it may be necessary to adjust the monitor setting refresh rate. This can be done by going into your display settings and changing the resolution or refresh rate.
