Looking back, I think the safest option would be to only change the selected GOP instance in case there are only two instances, where the default is virtual and the other is physical. It's worth noting that EDK2's ConSplitter implementation seems to distinguish between cases where there's a single physical GOP instance vs more, but I've only quickly skimmed the code so far, so I could be going completely off-base here. https://github.com/tianocore/edk2/blob/master/MdeModulePkg/Universal/Console/ConSplitterDxe/ConSplitterGraphics.c There are some interesting commits to the file. These presumably didn't make it into my laptop's firmware since the UEFI Shell's `ver` command reports that the "EFI Specification Revision" is "2.0" and the "EFI Build Version" is "20100426". https://github.com/tianocore/edk2/commit/8d4e1bd933f22a5e9223dc9923367f6f49b03b00 https://github.com/tianocore/edk2/commit/2fa996f9b769d6febb8a0d2e44e05f5ab10a1a0c Thanks.
