Setting up unraid for the first time. Had a 1080ti GPU installed and kept getting the blank screen after it going through the boot process. Finally found this thread and can confirm it has something to do with the display drivers. After removing the GPU and using the onboard HDMI it booted perfectly into the GUI. Once I get it all configured, I'll try reinstalling the GPU and see if it continues. But cheer for mentioning this! ❤️
