Hey,
So I read about similar issues, but my kinda weird.
I have ASRock deskmini a300 with Ryzen 5 2400g.
I use 3 Dell monitors with Daisy chaininng (one dp cable).
So I decided to downloaded amd adrenaline software, let the program update everything necessary. After that it asked for a restart. After the restart, at the beginning I see the windows loading icon, but after that the monitor display "no dp input", and that's it. Tried restarting couple of times and nothing. I thought that's there an issue with the drivers, which make sense. So, now the weird part, I connected the monitors to another PC, and I have the same problem. Tried different cable, same. Than I disconnected the main monitor, and connected directly to the second monitor, and it works. So the main monitor not working at all, only shows the logo of the PC and the booting and than "no dp input".
I never this issue before, and it happened immediately after the update.
Does it even possible? I mean, can an update somehow break the monitor?
