Second monitor broke after kernel update

My GPU, AMD R9 380, is no longer outputing to my second monitor after one of the last kernel updates. I have tried a fresh reinstall of the KDE spin and after updating the packages the same problem came up. I have tried changing xrandr output modes from terminal. This seems to be a kernel issue since reverting to an older version fixed the issue.

Edit: I believe the issue might be due to the fact that I'm using DVI-I to output to a VGA

xrand output:
