We are looking into this issue, and have updated the Release Notes to reflect the same.
In the meantime, please revert to your last working driver.
After updating the drivers to the latest version, the operating system (windows 10) no longer shows the device connected to the hdmi output, it just works properly with the previous driver
I realized that if you reinstall the driver it will temporarily work again and stop in 2 conditions, when you restart the computer, or when you remove the hdmi cable and then connect (with the system running, obviously)
I'm using the previous version and everything works perfectly
Edit: RX 580
Yes, that's exactly what happens to me. And it keeps happening...
I hope they fix it as soon as possible :(
I was searching online and found this (it worked tho):
Let's get this sorted out. Follow these workaround to see if it will resolve the issue,
