This issue has occurred with me multiple times, that my second monitor just up and goes away. For the first couple of times, support forums said to either reinstall drivers or disable crossifire which fixed the issue, but still it was super annoying. Now with the latest update of v24.4.1, there's simply no crossfire setting at all. I have no display on my second monitor and I have reinstalled drivers twice.
AMD boils my blood! pls help.
