I believe I may have solved the issue myself.
First, I have to download and install the Dell U2312HM driver. Upon successful installation and a reboot, Device Manager will report that the monitor is Dell U2312HM (Digital - DVI).
Second, download the latest driver (filename: win64_153318.exe, version 188.8.131.52.3496) from Intel and install it. A reboot is necessary. Device Manager will report that the display adapter is Intel HD Graphics 4600.
Up till this point in time, my display is working fine.
