Yea I fully understand that. I was just confused by his comment on saying sometimes the boot screen does not show, and other times it does show. To me that is just plain conflicting, it does not make sense, it cannot happen. Either the card has the EFI on it to display the boot screens or it does not. Though like I mentioned, if using 4K or higher settings or wrong protocols it is possible to not get the actual display of the boot screen because these are incompatible user settings

This is further funny sounding after he also stated he can always access the boot volume selection screen, which is an EFI screen. That would indicate he should always see the boot screen (as in the grey screen with apple logo and progress bar). Honestly I was just pointing out something that sounded strange because if it displays the boot screen randomly that is a sign something is wrong whether it is the hardware starting to fail or user settings.
