1080p only for me on an unmodded BIOS. I'm also waiting for the programmer to arrive to flash.I know this is the high Sierra thread. but.
Has anyone got a 4k monitor working from the Mini DisplayPort in Mojave? With default settings 2560x1440 is the highest resolution possible. 4k output works perfect under linux.
I've managed to get it somewhat working by changing the framebuffer-fbmem/stolenmem/unifiedmem/flags (+enable-hdmi20) in WhateverGreen. But if I change the stolenmem/fbmem values from default, some apps no longer work properly. e.g. Firefox just displays a white box (but you can still click around as if it was working), Google Chrome/Clover configurator have similar issues. (interestingly safari works OK).
So it looks like I need to increase the stolenmem/fbmem values but I don't know what values will get me 4K output and normal working apps.
FYI: I haven't modded my BIOS yet, I'm hoping it will unlock the DVMT options (?) so I can give those a try.
Does anyone have the cardreader working?
