That's all you need, or you can use 1 HDMI and 1 DP. I lprefer the 2 DP and vegafixup.
@kgp have you tried putting the native screen resolution in clover.

Sure.. does not have any effect.. I think it is not a problem related to clover.

The entire boot process is affected. Splash screen, Apple logo + progress bar and boot message in verbose boot. Everything with strongly reduced VGA like screen resolution.

As soon I reach login screen of Windows 10 and MacOS everything gets properly set.

No issues with Nvidia GPU with identical clover boot menu settings.

I did not need to do anything before the 10.13.4 update.

I don't use HDMI, so 2 DP and vegafixup kext.

Vega FE is "officially" supported by Apple in 10.13.4 from the documentations.

It seems to be an AMD issue. I would highly advise emailing AMD tech support and submit a ticket. Maybe they can release a vBIOS update in the future to fix this.

For me, it's always been the opposite. Even on my 1440p monitor, nVidia always stretched the splash screen/apple screen unless I enabled CSM.

Now with CSM disabled and Vega FE, no stretches.

But of course I'm not on a 4k monitor, I'll probably pull my hair out once I get a 4k monitor too :lol:

Can you update to F4c then reset the bios (it usually does when you update) and set up your settings along with the guide?

Sure, it's worth a shot. I'm in my "summer home" at the moment. I'll try again when I get back to Phoenix.

I just installed a iMac Pro system with a Vega Frontier for a client. I am not slagging off posters and hardware. This is not at all my intention. If you know a solution for the boot resolution issue, please go ahead and let me know about solutions.

The rest of your comments I simply try to ignore... in any case you are no one to tell me to stay away from my own thread...

Others are apparently allowed to permanently slag Nvidia GPUs.. But when I blame the Vegas, you blame on me, perfect.

Cheers,

KGP

LOL dudes! They're just video cars, not a religion. I like variety. It really sucked when no one made mac video cards.

For some people brands are a religion :D

I was hesitant to go with AMD, but I just went with what works best in my situation.

Have you tried both, HDMI and DP? Any difference? When I use DP, I get reduced graphics during boot up, when I use HDMI, everything is fine. It annoyed me so much that I ended up with using HDMI only.
