Second external monitor goes in standby

Currently using MacBook Pro for remote work, it would be model A2338. And second monitor was working when initially plugged in. I’m not sure what I did but out of nowhere the second monitor went black and when turning off and back on it goes into standby mode or says no signal… help!

Hey Krista310,

If you haven't already, we recommend working through this support article from Apple: If your external display is dark or low resolution - Apple Support

"Disconnect the display from your Mac, then reconnect it. It might help to turn off the display first.
Put your Mac to sleep, then wake it. On Mac laptop computers, you can close the lid for a few seconds, then open the lid again.
Choose Apple menu  > System Settings (or System Preferences), then click Displays. Press and hold the Option key to show the Detect Displays button, then click the button.
Restart your Mac. If you can't restart your Mac, press and hold its power button for about 10 seconds to turn it off. Then press and release the power button to turn it back on."

Let us know how it goes! Take care.
