I just bought an HDMI to DVI cable to plug in a second old monitor which worked yesterday before I updated the driver. Updated drivers this morning and now it won't even be recognized in Windows or the AMD software. I tried rolling back the drivers and it still did not work. I confirmed that the HDMI ports work with a regular HDMI cable but the converter cable no longer works. I am using a Vega 64 card with the main monitor going through the Display Port.
