UHD 630 - Can't boot with a 4K monitor, but 1080 monitors are fine

@jamesst20,

The base64 value depends upon the device type, if you are unsure then regenerate the 32MB Stolen Mem patch using Hackintool, make sure you select the correct PlatformID first :-

Thank you !

I tried with no results and then I updated my BIOS from F6 to F9g. Now it can boot with "OsxAptioFix3Drv" and DVMT Pre-Alloc of 64 MB just fine ! I no longer have to use "OsxAptioFix2Drv-free2000.efi".

However, the IGPU behavior with 4k monitors hasn't changed

@jamesst20,

That is good news ... at least we can eliminate "OsxAptioFix2Drv-free2000.efi" as the cause of the issue.

It's a strange issue for sure and not one i've come across before, so not really sure what to suggest ...

If it where me, i would try :-

• Using a different high-quality cable
• Use DP instead of HDMI (or vice-versa)
• Inject 4K monitor EDID (you'll have to dump it using linux or Windows)

Thats about all i can think of for now.
