You need a device specific GOP driver for graphics in UEFI.
Thanks … br

Subject: [edk2] How to use a VGA adapter
Hello,
I'm using the UDK2015 release and I want to enable the Graphic Output on a PCI
VGA adapter (PCI class code: 3, 0, 0). My VGA device doesn't provide any ROM.
In my FDF I've included the VgaMiniPortDxe and the VgaClassDxe. I haven't
enabled the CSM layer.
When my board boots the screen doesn't display anything. The PCI device is
enumerated (device found with pci command on the EFI shell).
Must I include another EFI driver to activate and/or initialize the VGA adapter
or are these 2 drivers sufficient to enable the VGA display?
Can I use the VGA without the CSM layer?
Note: the display had already worked with a GOP driver on an AMD GPU. Is it
possible to enable the GOP layer with the VGA layer?
Regards.
Cédric
