Older versions of the software worked. Now, DDM tells me that no supported monitors are connected.

I followed the first 3 steps of the procedure given in the sticky note for this group. I also uninstalled and reinstalled the software, and also did a hard reset of the monitor. Still the same problem.

System: PC (self-built with Asus Prime B360-D motherboard) DVI-D out port -- DVI to HDMI cable - U2415 HDMI-1 in port
