They receive no signal. The Dell monitors keep working fine. Setting `nomodeset` in grub returns the signal to the Asus monitor. Proof that monitor and cable is working fine, but nomodeset is not an acceptable work around. The monitor is also showing a picture during the BIOS boot phase. lsb_release -rd Description: Ubuntu 16.04 LTS uname -r 4.4.0-21-generic xrandr --listproviders Providers: number : 1 Provider 0: id: 0x59 cap: 0x9, Source Output, Sink Offload crtcs: 6 outputs: 4 associated providers: 0 name:ATI FirePro (FireGL) Graphics Adapter @ pci:0000:85:00.0 sudo lshw -c video [sudo] password for fhanik: *-display description: VGA compatible controller product: Cypress XT [FirePro V8800] vendor: Advanced Micro Devices, Inc.
