When using 18.4 drivers, all three of the monitors detected 3840x2160 max resolution (but I was running them at 2560x1440).


I was forced to update the drivers to 19.3 to run an application.  Since that time, 2 of the monitors detect properly as 3840x2160 max resolution (but I am running them at 2560x1440), but the third monitor detects a maximum resolution of 1920x1080.  The monitor with the issue is attached via the DVI to HDMI cable.


I have powered off the offending monitor, disconnected it from the PC, Rebooted the PC, Reattached the Monitor and powered it on.  It still detects at 1920x1080 resolution.


I tried to install the older drivers, but it brought up the new driver install.  How do I get Windows to detect the third monitor correctly?
