"Thank you for dealing with this! > A. Single-Out this Screen: > B. Single-Out this User: I didn't get both error so found out that this's a hardware issue and a misconfiguration within my macOS. If possible, could you tell me how to solve its misconfiguration?"

You are welcome.
Change the Resolution:
Perhaps you intermittently changed the screen's resolution? So, try other resolutions, seeing if you get this issue. If that does not work, then it is time to get this serviced: Change your Mac Display’s Resolution - Apple Support
Getting this Serviced:
A. Your Screen is Failing:
I have come across this on my 2017 Mac. The connector between the LogicBoard and the screen was loose, and I had to send it in for service 11 times. Being during COVID, I had to send this in. Today, the option to take this in for service is an option. So take this in for service, ASAP.
B. So, Get this Mac Serviced...
Contact Apple, and setup a Genius Bar Appointment or see an AASP (Apple Authorized Service Provider) in your local area.
A. Contact Apple:
- Contact Us - Choose Locations
- Proceed from there as Necessary
- NOTE: Due to the Coronavirus Pandemic, calls are taking a bit linger to get through. And, that makes sense, because many are at home working out-of-the-house or are taking classes over-the-web, this they have more time on their hands to contact Apple Support. So, it might take a bit to get through to Apple Support. But, just stay on the line, and someone will be with you.
Or...
B. Contact an AASP:
- Go Here: Find Locations - Apple Authorized Reseller
- Click: Service & Support
- Enter: your location information
- See: if there is an AASP nearby
- Contact: an AASP that shows up, and find out more about the services that they offer to fix the Mac
