Changing a VM's Screen Resolution

  1. Boot up a VM in ggRock.
  2. Put the VM in Admin Mode
  3. When in Admin mode, hold Shift and Press Windows - it will reboot.
  4. Click Troubleshoot>Advanced>UEFI Settings
  5. Go to Device Manager> OVMF Platform Configuration > Change Preferred Resolution



BIOS will still be 800x600 but once the VM is booting up, it'll kick in the new resolution.
