Hi All, This query is specific to Display Panel types for LCD interface
*CSM+Legacy VBIOS* LCD display panel with HDMI interface - No Display in BIOS but in Windows Display is seen *Non-CSM+GOP Driver* Both Display in BIOS and in Windows shows up EDID which is complaint for 1.3 is enabled, VBIOS does not support HDMI for Legacy Oprom's ? GOP driver constructs VBT based on Timing descriptors and supports HDMI interface for LFP/EFP panel types? Please enlighten me with the knowledge that is required for this specific issue There was a similar discussion in Open formus ( https://forums.geforce.com/default/topic/1003241/no-signal-from-hdmi-on-post-bios-only-when-windows-loads-/ Best Regards Galla _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
