This afternoon, I installed Windows Update: March 22, 2018—KB4089848 (OS Build 16299.334). As well as Radeon update 18.3.3. I first ran all windows updates, restarted, then updated the GPU driver with the help of Guru3d Display Driver Uninstaller. Now only one monitor will work.Just before this process, everything was working as it should.
Troubleshooting steps taken: Switched DVI cables, GPU outputs, and an HDMI cable. All cables and monitors are definitely working. After connecting the HDMI cable however, I can not get a signal back to either monitor through DVI. Used device manager to rollback drivers and update to new drivers. Used several old versions of AMD drivers. Reseated Graphics card. Nothing has worked. Windows will still not detect another monitor.
