P2419H, error running DDM
I recently purchased a Dell P2419H. When I try to install DDM (Version 1997) I get an error (Dell Display Manager error - This program requires a Dell supported monitor and connection, and compatible display driver.). The P2419H is connected via HDMI to an HP Pavilion 14 Laptop, running Windows 10 Home 1904.

The issue is likely the lack of a "compatible display driver", and if so you are probably using one of the recent Intel gfx drivers that have broken DDC/CI support. Try reverting to an older driver or updating to the latest available.
