I currently connect 4 monitors to my Radeon RX 570. All are functioning great on driver version: 22.19.162.4 (4/24/2017).
If i update the drivers to anything recent, 3 of the monitors continue to work. The 4th, my BenQ (connected via HDMI or Displayport) will be connected (seen in windows display settings), however, the monitor will display nothing and flashes "No Signal," resets and continues to fail.
If I roll the drivers back, all 4 are ok.
I have tried disconnecting all but my main monitor and the BenQ the symptom persists.
I have tried using all 4 of the last AMD drivers.
I have tried a 2019 driver from the Windows update.
I have tried using HDMI to the BenQ monitor
I have tried using display port to the BenQ monitor
I can provide much more information (resolutions, models of other monitors, etc.) if needed.
