Optiplex 9020: display does not wake after sleep

I managed to get a pretty functional install using a USB-audio adapter for speaker sound. My main issue is that the monitors do not wake up after sleep. I tried the darkwake=0 fix using clover configurator, but that did not solve the problem. Any ideas?

Update: Booting with the flag "darkwake=no" solved my problem.
Furthermore, I had this problem only since I started using dual monitors. During the initial installation/testing I used a single DP monitor. I attached a second HDMI monitor using a DP/HDMI cable (to test HDMI sound, which surprisingly works just fine) and my sleep/wake problems started.
