EDID on UEFI

[nexos]

Hello,
I am currently making a UEFI loader and have enumerated the GOP to find video modes. I know on VESA use use BIOS ints to access EDID to get monitor info. What is the equivalent on UEFI?
Thanks,

Code: Select all

EFI_EDID_ACTIVE_PROTOCOL

You can get it from a EFI_GRAPHICS_OUTPUT_PROTOCOL handle:

Code: Select all

        EFI_EDID_ACTIVE_PROTOCOL* edid = nullptr;
        m_bootServices->HandleProtocol(handleGraphicsOutputProtocol, &g_efiEdidActiveProtocolGuid, (void**)&edid));
